Cardiopulmonary and Respiratory Physiotherapy Research Topics: 20 Evidence-Based Ideas for 2026

Last updated: August 2026

Choosing a good cardiopulmonary physiotherapy research topic starts with identifying an important unanswered clinical question, not simply choosing a disease or treatment and asking whether physiotherapy works.

Cardiopulmonary physiotherapy—also called cardiorespiratory physiotherapy or respiratory physiotherapy—includes rehabilitation for people with respiratory and cardiovascular conditions, as well as critically ill patients whose mobility, respiratory function or exercise capacity has been affected by illness.

The research ideas below were selected from gaps and uncertainties identified in recent systematic reviews, meta-analyses, network meta-analyses, randomized controlled trials and other high-quality contemporary evidence.

Many broad questions have already been answered. For example, there is little value in another small study simply asking whether pulmonary rehabilitation helps people with COPD or whether exercise benefits people with heart failure.

The more useful questions increasingly concern:

the optimal exercise dose;
which patients respond best;
which rehabilitation components are actually necessary;
how treatment should be personalised;
which patients need supervision;
home, hybrid and telerehabilitation models;
long-term adherence and maintenance;
airway-clearance treatment selection;
exercise in complex or frail patients;
activity and participation rather than impairment alone;
cost-effectiveness and implementation in real clinical services.

These topics can be adapted for a physiotherapy thesis, dissertation, research proposal or clinical research project.

COPD and Pulmonary Rehabilitation Research Topics

1. Which People With COPD Need a Personalised Pulmonary Rehabilitation Programme?

Research topic idea:
Personalised Versus Standardised Pulmonary Rehabilitation in COPD: Can Comorbidities, Baseline Function and Symptom Burden Be Used to Improve Treatment Response?

Why this is still a research gap:
Pulmonary rehabilitation is clearly beneficial at a population level, but individual response varies considerably.

A large 2026 real-world study involving 922 people with COPD found that only around half achieved clinically meaningful improvement following pulmonary rehabilitation, and fewer maintained those improvements at one year. Age, baseline symptoms, lung function and functional capacity appeared to influence response.

At the same time, contemporary expert recommendations increasingly emphasise modifying exercise prescription when COPD coexists with cardiovascular disease, heart failure, diabetes, hypertension or sarcopenia.

Instead of asking whether pulmonary rehabilitation works, a more useful trial would ask whether selecting and progressing exercise according to a patient’s comorbidities and baseline phenotype produces better outcomes than a largely standardised programme.

Suggested design: Multicentre pragmatic stratified RCT comparing standard pulmonary rehabilitation with phenotype/comorbidity-tailored rehabilitation.

Evidence basis:
Van Raemdonck et al. Short- and Long-Term Responses to Pulmonary Rehabilitation in 922 Patients with COPD: A Real-World Database Study (2002-2019). Journal of Clinical Medicine. 2026. PMID: 41598731.

Machado et al. Tailored Exercise Prescription for People with COPD and Clinically Relevant Comorbidities: A Consensus Statement of the EXPERT Working Group and Experts in Pulmonary Rehabilitation. Sports Medicine. 2025. PMID: 41343041.

2. What Is the Optimal HIIT Protocol for COPD?

Research topic idea:
Optimising High-Intensity Interval Training in COPD: Interval Duration, Recovery Time, Intensity and Patient Selection

Why this is still a research gap:
High-intensity interval training (HIIT) may allow some people with COPD to accumulate substantial training at high workloads without requiring prolonged continuous effort.

A 2026 systematic review and meta-analysis comparing HIIT with moderate-intensity continuous training found different advantages across outcomes. HIIT showed benefits for six-minute walking performance and several muscle-function outcomes, while continuous training performed better for peak oxygen uptake.

However, the review concluded that further research is needed to identify optimal HIIT protocols.

The next question should therefore not be another simple HIIT-versus-continuous-training comparison. Researchers should determine the best combination of work interval, recovery interval, intensity and progression—and identify which patients are most likely to tolerate and benefit from it.

Suggested design: Multi-arm RCT comparing different HIIT prescriptions, stratified by COPD severity and exercise limitation.

Evidence basis:

3. Which Telerehabilitation Model Works Best for COPD?

Research topic idea:
Synchronous, Hybrid and Low-Technology Home Pulmonary Rehabilitation in COPD: Which Model Produces the Best Long-Term Outcomes and Adherence?

Why this is still a research gap:
The important question is increasingly not whether pulmonary telerehabilitation works, but how it should be delivered.

A 2026 systematic review and meta-analysis of 17 RCTs involving 1,658 participants found that telerehabilitation could achieve exercise-capacity outcomes broadly comparable with centre-based rehabilitation.

However, remote programmes varied substantially. Digitally supported programmes with synchronous professional supervision appeared more consistent than low-technology home programmes.

Long-term evidence was also less convincing: improvements in exercise capacity did not consistently translate into sustained increases in everyday physical activity.

Future research should compare specific delivery models rather than treating every form of “telerehabilitation” as the same intervention.

Suggested design: Pragmatic three-arm RCT comparing synchronous telerehabilitation, hybrid rehabilitation and minimally supervised home rehabilitation, with 12-month follow-up.

Evidence basis:
Li et al. Comparing Pulmonary Telerehabilitation and Center-Based Pulmonary Rehabilitation for Effectiveness and Adherence in Chronic Obstructive Pulmonary Disease: Systematic Review and Meta-Analysis of Randomized Controlled Trials. Journal of Medical Internet Research. 2026. PMID: 41996654.

4. Which Patients With COPD Benefit Most From Home Inspiratory Muscle Training?

Research topic idea:
Personalised Home-Based Inspiratory Muscle Training in COPD: Dose, Device Type and Baseline Inspiratory Muscle Weakness

Why this is still a research gap:
Inspiratory muscle training is relatively easy to deliver at home, but the optimal method and patient population remain uncertain.

A 2025 randomized trial compared a test-of-incremental-respiratory-endurance approach, conventional threshold IMT and sham training over an extended programme.

The novel training approach produced greater gains in inspiratory muscle performance, but the study was modest in size and adherence fell during the unsupervised period.

A larger study could answer several clinically useful questions simultaneously: Do people with objectively measured inspiratory muscle weakness benefit more? What is the minimum effective dose? How much supervision is necessary? And do gains in respiratory-muscle performance translate into less dyspnoea and better activity?

Suggested design: Multicentre RCT stratified by baseline inspiratory muscle strength, with objective adherence monitoring.

Evidence basis:

Bronchiectasis Physiotherapy Research Topics

5. Which Airway Clearance Technique Works Best During a Bronchiectasis Exacerbation?

Research topic idea:
Personalised Airway Clearance During Bronchiectasis Exacerbations: ACBT, Oscillating PEP or Exercise With Huffing

Why this is still a research gap:
Airway clearance is a core component of bronchiectasis physiotherapy, but there is surprisingly little high-quality evidence telling clinicians which technique should be used for a particular patient.

A 2026 RCT compared active cycle of breathing techniques (ACBT), oscillating positive expiratory pressure and walking with huffing during hospitalisation for a bronchiectasis exacerbation.

ACBT and exercise with huffing produced broadly similar short-term improvements in sputum clearance and health-related quality of life. Longer-term exacerbation results were exploratory and affected by loss to follow-up.

Instead of looking for one universal “best” technique, future studies could investigate whether treatment selection according to sputum volume, breathlessness, fatigue, patient preference and ability to self-manage produces better adherence and outcomes.

Suggested design: Multicentre pragmatic RCT with preference/responder analysis and 6–12 month exacerbation follow-up.

Evidence basis:
Phillips et al. Active Cycle of Breathing Technique Versus Oscillating Positive Expiratory Pressure Therapy Versus Exercise With Huffing During an Exacerbation of Bronchiectasis: A Randomised, Controlled Trial. Respirology. 2026. PMID: 42155584.

6. Can Home Pulmonary Rehabilitation Reduce Exacerbations in Bronchiectasis?

Research topic idea:
Long-Term Home-Based Pulmonary Rehabilitation in Bronchiectasis: Effects on Exercise Capacity, Physical Activity and Exacerbations

Why this is still a research gap:
Pulmonary rehabilitation is recommended for people with bronchiectasis who have impaired exercise capacity or breathlessness, but the evidence base remains much smaller than in COPD.

A 2025 single-centre RCT reported improvements in quality of life and other clinical outcomes after a home-based bronchiectasis rehabilitation programme.

That is encouraging, but a single-centre study is not enough to define an optimal rehabilitation pathway for a heterogeneous disease.

A larger study should determine whether benefits persist, whether rehabilitation meaningfully changes daily physical activity and exacerbation frequency, and whether treatment response differs in patients with coexisting COPD or different bronchiectasis phenotypes.

Suggested design: Multicentre pragmatic RCT with 12-month exacerbation and objectively measured physical-activity outcomes.

Evidence basis:
Min et al. Role of home-based pulmonary rehabilitation programs for disease progression and quality of life in patients with stable bronchiectasis: a single-center RCT. Frontiers in Medicine. 2025. PMID: 40740957.

Interstitial Lung Disease and Pulmonary Fibrosis Research Topics

7. Does CPET-Guided Exercise Prescription Improve Pulmonary Rehabilitation in ILD?

Research topic idea:
Cardiopulmonary Exercise Test-Guided Versus Standard Exercise Prescription in Interstitial Lung Disease

Why this is still a research gap:
Interstitial lung disease creates a particularly difficult exercise-prescription problem because exertional dyspnoea and oxygen desaturation can substantially limit training.

A 2025 systematic review identified 11 studies involving only 321 participants examining CPET-derived, tailored pulmonary rehabilitation. Only three were randomized trials.

Improvements were reported in peak oxygen uptake and work rate, but interventions were heterogeneous and follow-up was often short.

The authors specifically identified the need for standardised methods, consistent reporting and longer-term follow-up.

A direct trial could determine whether the added complexity and cost of CPET-guided prescription actually produces better clinical outcomes than careful prescription based on standard field tests and symptoms.

Suggested design: Multicentre RCT comparing CPET-guided rehabilitation with guideline-based standard prescription.

Evidence basis:
Bowhay et al. Utilisation of cardiopulmonary exercise testing for tailored pulmonary rehabilitation in people with interstitial lung diseases: A systematic review. Clinical Rehabilitation. 2025. PMID: 41168676.

8. Can Remote Monitoring Make Home Pulmonary Rehabilitation Sustainable in IPF?

Research topic idea:
Long-Term Remotely Monitored Home Pulmonary Rehabilitation in Idiopathic Pulmonary Fibrosis

Why this is still a research gap:
Home-based rehabilitation is attractive in idiopathic pulmonary fibrosis because travelling repeatedly to a centre can become increasingly difficult as the disease progresses.

A 2026 RCT tested a remotely monitored home programme using activity/heart-rate monitoring and pulse oximetry.

The study showed excellent completion and adherence and meaningful improvement in moderate-to-vigorous physical activity, but only 29 participants were randomised and the intervention lasted 12 weeks.

The next question is whether this model remains effective and safe across larger and more diverse IPF populations, longer periods and different stages of disease, particularly when oxygen desaturation or functional decline progresses.

Suggested design: Multicentre RCT with 12-month follow-up, safety monitoring and health-economic analysis.

Evidence basis:
Child et al. Remotely Monitored Home-based Pulmonary Rehabilitation in Idiopathic Pulmonary Fibrosis: Results of a Randomized Controlled Trial. Archives of Physical Medicine and Rehabilitation. 2026. PMID: 42532213.

Pulmonary Hypertension Research Topics

9. What Is the Optimal Exercise Programme for Pulmonary Arterial Hypertension?

Research topic idea:
Aerobic, Resistance and Breathing Training in Pulmonary Arterial Hypertension: A Head-to-Head Trial of Exercise Components and Dose

Why this is still a research gap:
Supervised exercise is increasingly accepted for clinically stable pulmonary arterial hypertension, but clinicians still have limited evidence for choosing between exercise components.

A 2026 network meta-analysis included 16 trials and 644 participants. Different combinations of aerobic, resistance and breathing training produced promising signals for different outcomes.

However, evidence certainty was generally low or very low, active-versus-active comparisons were limited, and the authors cautioned against interpreting treatment rankings as proof of superiority.

They specifically called for larger, subtype-stratified trials with standardised exercise prescriptions, harmonised safety reporting and longer follow-up.

Suggested design: Multicentre active-comparator RCT stratified by pulmonary-hypertension subtype and functional class.

Evidence basis:
Hua et al. Effects of different exercise-based rehabilitation programs in adults with pulmonary arterial hypertension and related pulmonary hypertension populations: a systematic review and network meta-analysis. BMC Sports Science, Medicine and Rehabilitation. 2026. PMID: 42421065.

Asthma Physiotherapy Research Topics

10. Which Patients With Asthma Actually Benefit From Rehabilitation?

Research topic idea:
Phenotype-Specific Pulmonary Rehabilitation in Adults With Asthma: Exercise, Breathing Retraining and Combined Rehabilitation

Why this is still a research gap:
Rehabilitation interventions for asthma include exercise, breathing retraining and combined programmes, but the evidence remains difficult to translate into practice.

A 2025 systematic review evaluated 36 randomized trials and found substantial heterogeneity between interventions and outcomes. Overall certainty was low or very low, preventing firm conclusions about several rehabilitation approaches.

This creates a strong opportunity to move away from studies combining all adults with asthma into one group.

Future research could identify whether rehabilitation works differently in people with severe asthma, dysfunctional breathing, obesity, low fitness, high anxiety related to breathlessness or exercise avoidance.

Suggested design: Phenotype-stratified RCT comparing tailored rehabilitation with usual asthma management.

Evidence basis:
Zampogna et al. Effectiveness of Rehabilitation Interventions in Adults With Asthma: A Systematic Review and Meta-analysis. American Journal of Physical Medicine and Rehabilitation. 2025. PMID: 38958276.

Cystic Fibrosis Physiotherapy Research Topics

11. Can Exercise Replace Some Traditional Airway Clearance Sessions in Cystic Fibrosis?

Research topic idea:
Exercise as an Airway Clearance Technique in Cystic Fibrosis: A Long-Term Multicentre Trial of Safety, Efficacy, Treatment Burden and Cost

Why this is still a research gap:
This is particularly relevant as modern cystic fibrosis treatment changes disease burden and raises questions about how traditional physiotherapy routines should evolve.

A 2026 randomized pilot trial tested daily exercise as an airway clearance technique (ExACT) in people with CF receiving elexacaftor/tezacaftor/ivacaftor.

Participants allocated to ExACT stopped their other airway-clearance techniques during the 28-day intervention. The approach appeared feasible and safe in the pilot study.

Crucially, the authors recommended progression to a definitive longer-term multicentre trial evaluating safety, efficacy and cost-effectiveness.

That makes this unusually direct as a research recommendation.

Suggested design: Multicentre non-inferiority RCT with pulmonary exacerbations, lung function, treatment burden, adherence and cost-effectiveness outcomes.

Evidence basis:
Urquhart et al. Safety, feasibility and efficacy of exercise as an airway clearance technique in cystic fibrosis: a randomised pilot feasibility trial. Thorax. 2026. PMID: 41033804.

Long COVID Physiotherapy Research Topics

12. Should Long COVID Rehabilitation Be Prescribed According to Symptom Phenotype?

Research topic idea:
Phenotype-Stratified Physiotherapy for Long COVID: Exercise-Based Rehabilitation Versus Pacing and Energy-Conservation Pathways

Why this is still a research gap:
Long COVID is too heterogeneous for a single rehabilitation prescription.

A 2026 systematic review and meta-analysis of 10 randomized trials found that exercise programmes could improve several cardiopulmonary and functional outcomes in people with post-COVID condition.

However, this should not be interpreted to mean that progressive exercise is appropriate for every person with Long COVID.

Contemporary physiotherapy guidance recommends specific assessment for fatigue, post-exertional malaise/post-exertional symptom exacerbation, orthostatic intolerance, respiratory symptoms and other red flags before selecting rehabilitation.

This creates an important next research question: do outcomes improve when patients are stratified before treatment, with exercise-based rehabilitation offered to appropriate patients and pacing/energy-management strategies prioritised when post-exertional symptom exacerbation is present?

Suggested design: Pragmatic stratified trial comparing phenotype-guided rehabilitation with non-stratified usual rehabilitation. Patients with post-exertional symptom exacerbation should not simply be randomised to forced progressive exercise.

Evidence basis:
Khuna et al. Effects of exercise programs on cardiopulmonary function and signs and symptoms in patients with post-COVID-19 condition: a systematic review and meta-analysis. Frontiers in Medicine. 2026. PMID: 41924744.

Reeves et al. Physiotherapy management of Long-COVID: an evidence-based approach. Brazilian Journal of Physical Therapy. 2026. PMID: 42320154.

ICU and Critical Care Physiotherapy Research Topics

13. Should ICU Mobilisation Dose Be Different for Frail and Non-Frail Patients?

Research topic idea:
Age- and Frailty-Specific Mobility Dose in Mechanically Ventilated ICU Patients

Why this is still a research gap:
“Early mobilisation” is often discussed as though it were one intervention, but mobilisation includes several variables: when it starts, how often it occurs, how intense it is and how much total activity the patient completes.

A 2025 multicentre prospective study included 422 mechanically ventilated patients across 22 ICUs.

The rehabilitation variables associated with later independence differed according to age and frailty. For example, intensity and earlier mobilisation appeared particularly relevant in some groups, while frequency and duration appeared more important among frail older adults.

These observational results cannot establish causality, but they strongly support testing individualised mobility prescriptions instead of one standard ICU dose.

Suggested design: Multicentre adaptive or stratified RCT according to age and Clinical Frailty Scale.

Evidence basis:
Watanabe et al. Impact of mobility dose levels on functional outcomes in individualised patients with critical illness: A multicentre prospective observational cohort study in Japan. Clinical Rehabilitation. 2025. PMID: 41252336.

14. Who Benefits From Exercise Rehabilitation After ICU Discharge?

Research topic idea:
Personalised Post-ICU Exercise Rehabilitation: Identifying Responders and the Optimal Delivery Model After Critical Illness

Why this is still a research gap:
Recovery does not end when somebody leaves the ICU.

A systematic review and meta-analysis of 14 randomized trials involving 1,259 critical-illness survivors found that post-discharge exercise rehabilitation could improve aerobic capacity and the physical component of health-related quality of life, with some evidence for improvement in depression.

However, ICU survivors are extremely heterogeneous. Some leave hospital almost independent, while others have profound weakness, respiratory limitations, cognitive problems and post-intensive-care syndrome.

Rather than another broad exercise-versus-usual-care trial, research should determine who requires structured rehabilitation, what intensity is appropriate, and whether supervised, home or hybrid programmes work best for different recovery profiles.

Suggested design: Stratified pragmatic RCT using discharge mobility/function to assign rehabilitation pathways.

Evidence basis:
Cazeta et al. Effects of exercise interventions on functioning and health-related quality of life following hospital discharge for recovery from critical illness: A systematic review and meta-analysis of randomized trials. Clinical Rehabilitation. 2024. PMID: 38556253.

Heart Failure and Cardiac Rehabilitation Research Topics

15. What Is the Best Exercise Modality for HFpEF?

Research topic idea:
Head-to-Head Exercise Training in Heart Failure With Preserved Ejection Fraction: Aerobic, Resistance, Interval and Inspiratory Muscle Training

Why this is still a research gap:
Heart failure with preserved ejection fraction (HFpEF) is an important rehabilitation population, but exercise prescription remains much less certain than clinicians would ideally like.

A 2026 systematic review and network meta-analysis included 12 RCTs and 602 participants.

Several exercise modalities showed potential benefits for exercise-capacity outcomes, including continuous aerobic exercise, moderate-intensity aerobic training and inspiratory muscle training.

However, the certainty of evidence was rated very low for every outcome.

The network therefore cannot confidently tell clinicians which programme to prescribe.

Direct active-versus-active trials with standardised training doses are needed.

Suggested design: Multicentre head-to-head RCT comparing two or more clearly defined exercise prescriptions, ideally with CPET-based outcomes and long-term clinical follow-up.

Evidence basis:
Henríquez-Jurado et al. Effectiveness of different exercise modalities in Heart Failure with preserved Ejection Fraction. A systematic review with network meta-analysis. Brazilian Journal of Physical Therapy. 2026. PMID: 41997085.

Explore related research: Search PhysioKeys for exercise rehabilitation in HFpEF →

16. How Much Resistance Training Should Be Added to Aerobic Training in Heart Failure?

Research topic idea:
Optimising Combined Resistance and Aerobic Training in Heart Failure: Dose, Sex and Ejection-Fraction Phenotype

Why this is still a research gap:
A 2026 systematic review and meta-analysis found that combining muscle-strengthening exercise with aerobic training produced greater improvements in cardiorespiratory fitness, six-minute walk distance and upper-body strength than aerobic training alone in HFrEF.

However, the evidence base had a major representation problem: 89% of included participants had reduced ejection fraction and only 17% were women.

The authors specifically concluded that further evidence is needed in HFpEF.

A useful next study would therefore determine the optimal amount of resistance training while intentionally recruiting women and people across heart-failure phenotypes.

Suggested design: Dose-matched RCT comparing aerobic training alone with different aerobic/resistance combinations, stratified by sex and ejection fraction.

Evidence basis:
Terada et al. Combined strength and aerobic training vs. aerobic training alone in patients with heart failure: A systematic review and meta-analysis. Journal of Sport and Health Science. 2026. PMID: 41881310.

17. What Is the Optimal Cardiac Rehabilitation Programme for Frail Older Adults With Heart Failure?

Research topic idea:
Frailty-Adapted Exercise Rehabilitation in Older Adults With Heart Failure

Why this is still a research gap:
Traditional cardiac rehabilitation programmes may not be designed around frailty.

A 2026 systematic review found only six intervention studies specifically evaluating exercise in frail older adults with heart failure.

Results were encouraging: exercise was associated with improvements across frailty, physical function, activity and quality-of-life outcomes.

However, interventions varied considerably in modality and duration, and the evidence base remains small.

This population may require slower progression, greater resistance/functional training, balance work, symptom-guided intensity and different delivery models than younger, non-frail cardiac rehabilitation populations.

Suggested design: Multicentre RCT comparing frailty-adapted multicomponent rehabilitation with conventional cardiac rehabilitation.

Evidence basis:
Sáez-Nieto et al. Effects of exercise training on frail older adults with heart failure: a systematic-review. Frontiers in Aging. 2026. PMID: 41969362.

18. How Can Cardiac Rehabilitation Participation Be Increased After Myocardial Infarction?

Research topic idea:
Patient-Centred Rehabilitation Choice After Myocardial Infarction: Can Tailored Counselling Plus Centre-Based and Telehealth Options Increase Participation?

Why this is still a research gap:
An intervention cannot benefit patients who never participate.

A 2026 prospective analysis of people following acute myocardial infarction found that approximately one in five did not participate in either centre-based or telehealth cardiac rehabilitation.

Non-participants tended to be older, and the most common reason was lack of interest or failure to recognise the need for rehabilitation.

Simply making telerehabilitation available therefore does not solve every participation barrier.

A useful study would test whether patient-centred counselling, shared decision-making and an explicit choice between centre, hybrid and remote pathways increases actual enrolment and completion—particularly among older adults.

Suggested design: Pragmatic randomized implementation trial using cardiac-rehabilitation participation and completion as primary outcomes.

Evidence basis:
van Mierlo et al. Patient characteristics of non-participants and reasons for non-participation in cardiac (tele)rehabilitation—a prospective analysis. Frontiers in Rehabilitation Sciences. 2026. PMID: 42254476.

Cardiac Surgery Physiotherapy Research Topics

19. What Is the Optimal Inspiratory Muscle Training Protocol After CABG?

Research topic idea:
Dose and Timing of Inspiratory Muscle Training During Phase I and II Rehabilitation After Coronary Artery Bypass Grafting

Why this is still a research gap:
Inspiratory muscle training after CABG has enough evidence that another simple IMT-versus-no-IMT trial would be less informative.

A systematic review and meta-analysis of 15 studies found that IMT could improve exercise capacity and inspiratory-muscle strength and may reduce hospital length of stay during early rehabilitation.

However, evidence quality ranged from very low to moderate and several outcomes were affected by substantial risk of bias.

An important next step is to determine the best training intensity, timing, progression and patient-selection criteria, including whether patients with pre-existing inspiratory muscle weakness gain the most.

Suggested design: Multicentre dose-response RCT stratified according to preoperative inspiratory muscle strength.

Evidence basis:
Araújo et al. Inspiratory Muscle Training in Phase 1 and 2 Postoperative Cardiac Rehabilitation Following Coronary Artery Bypass Graft Surgery: Systematic Review With Meta-Analysis. Physical Therapy and Rehabilitation Journal. 2024. PMID: 38624192.

20. How Early Should Patients Be Mobilised After Cardiac Surgery?

Research topic idea:
Mobilisation Within 24 Hours After Cardiac Surgery: Effects on Delirium, Functional Recovery and Length of Stay

Why this is still a research gap:
Early mobilisation following cardiac surgery is logical and commonly encouraged, but the optimal timing has not been established.

A 2026 randomized pilot study examined mobilisation within 24 hours following cardiac surgery.

Early mobilisation appeared safe and was associated with shorter delirium duration, although the study was small and did not demonstrate a clear statistically significant reduction in overall delirium incidence.

The authors specifically recommended testing these preliminary findings in larger multicentre trials.

Future studies should also determine whether earlier mobilisation improves walking independence, ICU length of stay, discharge destination and long-term physical function—not delirium alone.

Suggested design: Multicentre RCT comparing protocolised mobilisation within 24 hours with current usual-care timing.

Evidence basis:
Xu et al. The effect of early mobilization of post-cardiac surgery patients on delirium: a pilot study. European Journal of Physical and Rehabilitation Medicine. 2026. PMID: 41706053.

What Types of Research Work Well in Cardiopulmonary Physiotherapy?

The best study design depends on the question.

Dose-Response Trials

Useful when treatment already works but the optimal amount is uncertain.

Example: Comparing different HIIT interval prescriptions in COPD.

Active-Comparator RCTs

Particularly valuable when multiple accepted treatments already exist.

Example: Comparing ACBT with oscillating PEP for bronchiectasis rather than comparing airway clearance with no treatment.

Stratified and Personalised Rehabilitation Trials

Useful in heterogeneous conditions where the same programme is unlikely to suit everybody.

Example: Stratifying Long COVID rehabilitation according to post-exertional symptom exacerbation.

Non-Inferiority Trials

Useful when a simpler, cheaper or less burdensome intervention may achieve similar outcomes.

Example: Determining whether exercise can replace selected conventional airway-clearance sessions in cystic fibrosis.

Pragmatic and Implementation Trials

Useful when an intervention has efficacy evidence but participation or real-world delivery remains poor.

Example: Testing whether offering patients a choice of centre-based, hybrid and tele-cardiac rehabilitation improves participation.

Prognostic and Responder Studies

Useful for determining who benefits from an established treatment.

Example: Identifying which patients with COPD maintain clinically meaningful gains one year after pulmonary rehabilitation.

Qualitative and Mixed-Methods Research

Important when treatment burden, adherence, patient preferences or service delivery influence outcomes.

Example: Understanding why people decline cardiac rehabilitation after myocardial infarction.

Health-Economic Research

Increasingly important as rehabilitation moves into home and digital environments.

Example: Comparing the cost-effectiveness of remotely monitored pulmonary rehabilitation with centre-based rehabilitation.

How to Turn One of These Ideas Into a Cardiopulmonary Physiotherapy Thesis

A research topic is only the starting point.

Before finalising your question:

Define the population precisely.
“Respiratory patients” is usually far too broad. COPD severity, bronchiectasis phenotype, ILD subtype, heart-failure phenotype, frailty and ICU status can all materially change the research question.
Define the intervention properly.
Exercise research should report frequency, intensity, time, type, volume and progression.
Measure the treatment actually completed.
Prescribing three sessions per week does not mean three sessions were performed.
Choose a clinically meaningful comparator.
When effective rehabilitation already exists, an active comparator is often more valuable than no treatment.
Prioritise patient-important outcomes.
Improvements in inspiratory pressure or VO₂ peak can be useful, but patients may care more about breathlessness, walking, exacerbations, independence and participation.
Consider longer-term outcomes.
A programme that improves a six-minute walk test at eight weeks but produces no lasting change in physical activity may have limited long-term impact.
Consider disease heterogeneity.
Cardiopulmonary populations frequently have multiple comorbidities, and the same exercise prescription may not be suitable for everyone.
Include safety outcomes where appropriate.
This is particularly important in pulmonary hypertension, ILD with exertional desaturation, critical illness, Long COVID and early cardiac rehabilitation.
Measure adherence and treatment burden.
A theoretically effective intervention is less useful if patients cannot sustain it.
Check feasibility.
A high-quality student project that can realistically recruit and retain enough participants is usually more valuable than an ambitious but underpowered study.

Before You Finalise Your Research Topic

Research gaps change as new trials and systematic reviews are published.

Before committing to a thesis or project, search the latest evidence to confirm that the question is still genuinely unanswered.

Look particularly at:

recent systematic reviews and meta-analyses;
randomized controlled trials published after those reviews;
limitations identified by review authors;
recommendations for future research;
ongoing trials that may answer your question before your project is completed.

You can use PhysioKeys to search current physiotherapy and rehabilitation research across respiratory, pulmonary, cardiac and critical-care conditions.

A useful research project should not simply confirm that rehabilitation works. It should help us understand what to prescribe, how much to prescribe, who needs it, how to deliver it, and whether the benefits actually matter in everyday life.

Pediatric Physiotherapy Research Topics Ideas for Your Thesis or Project

Al-Jallad — Sun, 16 Aug 2026 21:08:09 +0000

Choosing a research topic for a pediatric physiotherapy thesis or project can be difficult. Pediatric physiotherapy covers a very wide range of conditions, ages, interventions, and outcomes—from early intervention in premature infants to rehabilitation for cerebral palsy, developmental coordination disorder, scoliosis, juvenile arthritis, autism, and other childhood conditions.

The pediatric physiotherapy research topics below are not just random ideas. They are based on gaps and uncertainties identified in systematic reviews, meta-analyses, and clinical trials. These gaps include questions about the best type of intervention, optimal exercise dose, long-term effectiveness, adherence, home-based rehabilitation, and which children are most likely to respond to treatment.

The exact research question can, of course, be adapted depending on the population, equipment, clinical setting, and time available for your thesis or project.

20 Pediatric Physiotherapy Research Topic Ideas

1. Comparing Different Types of Balance Training in Children With Cerebral Palsy

Research topic idea:
The Effectiveness of Task-Specific Balance Training Versus Strength and Balance Training on Postural Control and Gross Motor Function in Children With Cerebral Palsy

Exercise appears to improve balance and gross motor function in children with cerebral palsy. However, a systematic review and meta-analysis found that there are not enough studies examining individual exercise types to make definitive recommendations about which form of training is most effective.

This makes direct comparisons between balance interventions a useful area for future research.

Research basis: Xiao et al. found beneficial effects of exercise but specifically highlighted the lack of evidence comparing individual exercise types. [1]

2. Progressive Resistance Training in Non-Ambulatory Children With Cerebral Palsy

Research topic idea:
The Safety and Effectiveness of Progressive Resistance Exercise in Non-Ambulatory Children and Adolescents With Cerebral Palsy

Progressive resistance exercise can increase muscle strength in young people with cerebral palsy, but most available research involves ambulatory participants.

A systematic review and meta-regression specifically identified a lack of evidence for progressive resistance exercise in non-ambulatory people with cerebral palsy.

Possible outcomes could include strength, transfers, wheelchair mobility, functional independence, fatigue, and participation.

Research basis: Bania et al. identified insufficient evidence in non-ambulatory people with cerebral palsy. [2]

3. Home-Based Virtual Reality Rehabilitation for Cerebral Palsy

Research topic idea:
Home-Based Virtual Reality Rehabilitation Versus Conventional Home Exercise for Improving Motor Function and Participation in Children With Cerebral Palsy

Virtual reality may allow children to perform larger amounts of rehabilitation at home while making repetitive practice more engaging.

A systematic review and meta-analysis found promising improvements in hand function, gross motor function, and walking capacity with home-based virtual reality. However, the authors called for adequately powered, well-designed randomized controlled trials using reliable outcome measures.

Future studies could also examine adherence and whether children actually continue using these programs outside supervised therapy.

Research basis: Hao et al. systematic review and meta-analysis. [3]

4. Long-Term Physical Activity Participation in Children With Cerebral Palsy

Research topic idea:
Do Physiotherapy-Led Physical Activity Programs Produce Long-Term Improvements in Sports and Physical Activity Participation in Children With Cerebral Palsy?

Improving a child’s performance during a rehabilitation program does not necessarily mean that the child becomes more physically active afterwards.

A systematic review found that improvements in attendance and involvement in physical activity following interventions may only be short term. Longer follow-up and better measurement of participation are needed.

A thesis could therefore follow children for 6 or 12 months after an intervention rather than measuring outcomes immediately after treatment.

Research basis: Kilgour et al. concluded that sustained participation remains uncertain and longer follow-up is required. [4]

5. Task-Oriented Versus Integrated Training for Developmental Coordination Disorder

Research topic idea:
Task-Oriented Training Versus Integrated Motor Training for Children With Developmental Coordination Disorder

Different motor interventions may affect different aspects of developmental coordination disorder (DCD).

A recent network meta-analysis found that task-oriented training ranked highly for overall motor function, while integrated training ranked highly for balance and manual dexterity. However, the evidence included limited direct head-to-head comparisons between interventions.

A direct randomized comparison could therefore provide clinically useful information.

Research basis: Dong et al. network meta-analysis of randomized controlled trials. [5]

6. Optimal Duration of Exercise Intervention for Developmental Coordination Disorder

Research topic idea:
Does a 12-Week Motor Training Program Produce Better Outcomes Than an 8-Week Program in Children With Developmental Coordination Disorder?

How long should children with DCD receive motor training?

The available evidence suggests that interventions lasting longer than eight weeks may produce larger effects, but this finding does not establish the optimal treatment duration.

A trial directly comparing different intervention durations could examine motor function, balance, participation, and whether improvements remain after treatment finishes.

Research basis: Dong et al. reported greater effects with interventions lasting longer than eight weeks but also highlighted substantial uncertainty and heterogeneity. [5]

7. Treadmill Versus Neuromuscular Exercise in Young Children With Down Syndrome

Research topic idea:
Treadmill Training Versus Neuromuscular Exercise for Improving Early Motor Development in Children With Down Syndrome

Therapeutic exercise can improve aspects of motor development in young children with Down syndrome, but the optimal exercise prescription remains uncertain.

A systematic review identified both aerobic and neuromuscular exercise approaches and highlighted heterogeneity and small sample sizes within the available evidence.

Future studies could compare treadmill training, neuromuscular exercise, or a combination of both on walking onset, gait speed, balance, and gross motor development.

Research basis: Rodríguez-Grande et al. systematic review and meta-analysis. [6]

8. Which Exercise Is Best for Balance in Children With Down Syndrome?

Research topic idea:
Comparative Effects of Different Exercise Programs on Postural Control in Children With Down Syndrome

Exercise appears to improve postural control in people with Down syndrome, but certainty in the evidence remains low.

A 2025 systematic review and meta-analysis specifically recommended larger randomized trials comparing different types of exercise or exercise with other strategies.

Potential interventions could include balance training, strengthening, sensorimotor exercise, treadmill training, or interactive exercise programs.

Research basis: Zolghadr et al. recommended stronger trials comparing exercise approaches. [7]

9. Early Family-Centered Intervention for Very Preterm Infants

Research topic idea:
The Effect of Early Family-Centered Motor Intervention on Motor Development in Very Preterm Infants

For very preterm infants, the family is an important part of early rehabilitation.

Recent evidence suggests that early family-centered interventions may improve later motor, cognitive, and behavioral development. Future studies could examine when these interventions should begin and which components provide the greatest benefit.

For example, researchers could compare an intervention beginning during NICU admission with a similar intervention beginning after discharge.

Research basis: Raghupathy et al. systematic review and meta-analysis of family-centered care in very preterm infants. [8]

10. What Is the Optimal Dose of Parent-Administered Exercise for Preterm Infants?

Research topic idea:
Dose-Response Relationship Between Parent-Administered Motor Exercise and Development in Preterm Infants

More physiotherapy is not automatically better—but in premature infants, dose may be particularly important.

A randomized controlled trial found no overall difference between intervention and control groups at three months corrected age, but infants receiving a larger total intervention dose demonstrated better motor outcomes.

This creates an interesting question about the minimum effective dose of parent-delivered motor intervention.

Research basis: Øberg et al. randomized controlled trial investigating intervention dose in the NICU. [9]

11. Physiotherapy for Positional Plagiocephaly

Research topic idea:
Parent Positioning Education Versus Multimodal Physiotherapy for Infants With Positional Plagiocephaly

Physiotherapists may use parent education, positioning strategies, manual therapy, and motor stimulation when managing infants with nonsynostotic positional head deformities.

A systematic review found potentially positive effects on cranial asymmetry and motor development, but the available studies had small samples and substantial risk of bias.

A larger study could compare education and positioning alone with a multimodal physiotherapy program.

Research basis: Cabrera-Martos et al. systematic review of physical therapist interventions for positional head deformities. [10]

12. Which Infants Benefit Most From START-Play?

Research topic idea:
Does the Effectiveness of START-Play Differ According to the Severity of Motor Delay in Infants?

Not every child responds to an intervention in the same way.

A multicenter randomized clinical trial found that START-Play produced several positive cognitive, fine motor, reaching, and problem-solving effects in infants with significant motor delay, whereas benefits were less evident in infants with milder delays.

Further research could investigate how severity, age, diagnosis, or baseline motor ability influences response to this type of intervention.

Research basis: Harbourne et al. multisite randomized clinical trial. [11]

13. Scoliosis-Specific Exercise Versus General Exercise

Research topic idea:
Physiotherapeutic Scoliosis-Specific Exercise Versus General Therapeutic Exercise for Adolescent Idiopathic Scoliosis

Physiotherapeutic scoliosis-specific exercises such as the Schroth approach are widely used in adolescent idiopathic scoliosis, but uncertainty remains about how much better they are than general exercise.

A Cochrane review found very low-certainty evidence for several comparisons and considerable heterogeneity between studies.

Future research could directly compare standardized PSSE and general exercise programs using Cobb angle, angle of trunk rotation, quality of life, self-image, and treatment adherence.

Research basis: Romano et al. Cochrane systematic review. [12]

14. Adding Scoliosis-Specific Exercise to Bracing

Research topic idea:
Long-Term Effects of Physiotherapeutic Scoliosis-Specific Exercise Combined With Bracing Versus Bracing Alone in Adolescents With Idiopathic Scoliosis

Some evidence suggests that combining PSSE with bracing may improve Cobb angle compared with bracing alone, but confidence in this evidence remains limited.

A particularly useful future study would follow patients for longer periods and examine outcomes beyond immediate Cobb-angle changes.

Potential outcomes include curve progression, brace adherence, quality of life, progression beyond clinically important thresholds, and eventual requirement for surgery.

Research basis: The Cochrane review by Romano et al. described the available evidence as sparse and generally low or very low certainty. [12]

15. Long-Term Effects of Exercise Therapy in Juvenile Idiopathic Arthritis

Research topic idea:
Long-Term Effects of Physiotherapy-Led Exercise on Pain and Function in Children With Juvenile Idiopathic Arthritis

Physiotherapy interventions including exercise, Pilates, and aquatic exercise may reduce lower-limb pain in juvenile idiopathic arthritis (JIA).

However, much of the available evidence evaluates outcomes over relatively short periods.

A recent systematic review specifically called for research investigating whether the benefits of physical therapies continue beyond three months.

Research basis: Fellas et al. systematic review and meta-analysis. [13]

16. Improving Home Exercise Adherence in Juvenile Idiopathic Arthritis

Research topic idea:
Can a Behavioural and Digital Support Program Improve Exercise Adherence in Children With Juvenile Idiopathic Arthritis?

Having an effective exercise program is not enough if children do not perform it.

A review of exercise adherence in JIA found large variations in adherence and identified barriers including time pressure, symptoms, lack of enjoyment, and insufficient motivation. Motivation, symptom management, and social support were identified as facilitators.

A thesis could evaluate reminders, gamification, parent support, physiotherapist feedback, or symptom-adaptive exercise prescription.

Research basis: Hu et al. concluded that strategies specifically designed to improve exercise adherence in children and adolescents with JIA are needed. [14]

17. Risk-Stratified Physiotherapy for Pediatric Chronic Pain

Research topic idea:
Risk-Stratified Multimodal Physiotherapy Versus Standard Physiotherapy for Children With Chronic Musculoskeletal Pain

Children with chronic pain can differ substantially in their psychological, social, and physical risk factors.

An exploratory study used the Pediatric Pain Screening Tool (PPST) to guide different levels of multimodal physiotherapy and reported promising improvements in pain and psychological outcomes.

The next important step would be a larger controlled trial comparing risk-stratified physiotherapy with usual physiotherapy.

Research basis: Ceniza-Bordallo et al. feasibility study of PPST-guided multimodal physiotherapy. [15]

18. Aquatic Versus Land-Based Exercise for Children With Autism Spectrum Disorder

Research topic idea:
Long-Term Effects of Aquatic Versus Land-Based Exercise on Motor Skills and Participation in Children With Autism Spectrum Disorder

A randomized controlled trial published in 2026 compared aquatic and land-based exercise in young children with autism spectrum disorder and reported greater improvements in several motor and quality-of-life outcomes following aquatic training.

Further research could investigate whether these improvements persist after treatment finishes and whether aquatic programs improve real-world participation and physical activity.

Adherence, parental preference, accessibility, and cost could also be investigated.

Research basis: Albadry et al. randomized controlled trial. [16]

19. Exercise Prescription for Children With Muscular Dystrophy

Research topic idea:
Comparing Aerobic and Resistance Exercise Prescription in Children With Muscular Dystrophy

Exercise prescription in muscular dystrophy remains challenging because clinicians must balance the potential benefits of physical activity against concerns about excessive muscular loading.

A systematic review and meta-analysis found modest improvements in walking endurance but uncertainty regarding strength and insufficient information for several types of muscular dystrophy.

The authors specifically recommended investigating which types of muscular exercise produce the greatest benefits.

A pediatric study could focus on exercise type, intensity, fatigue, safety, functional mobility, and recovery.

Research basis: Gianola et al. systematic review and meta-analysis. [17]

20. Physiotherapy After Cardiac Surgery in Children With Congenital Heart Disease

Research topic idea:
What Is the Optimal Physiotherapy Rehabilitation Program for Children After Congenital Heart Surgery?

Children with congenital heart disease who undergo cardiac surgery may be at risk of delayed motor development, but there is relatively little evidence defining the best physiotherapy rehabilitation pathway.

A scoping review found major variation in the interventions and rehabilitation formats used and specifically called for research identifying the optimal format of physiotherapy provision.

Possible comparisons include inpatient rehabilitation versus inpatient plus home rehabilitation, supervised exercise versus parent-led exercise, or standard follow-up versus physiotherapist-supported telerehabilitation.

Research basis: Clarke et al. scoping review of physiotherapy-delivered rehabilitation following congenital heart surgery. [18]

Choosing the Right Pediatric Physiotherapy Research Topic

A good thesis topic does not necessarily need to investigate a completely new treatment. Some of the most clinically useful research questions come from areas where we already know an intervention probably works but do not yet know how to use it optimally.

For example:

Which type of exercise is best?
What is the optimal intensity or dose?
Which children are most likely to respond?
Are the improvements maintained after six or twelve months?
Does a home-based program work as well as supervised treatment?
How can adherence to physiotherapy be improved?
Do improvements in impairments such as strength and balance translate into better activity and participation?

These questions can often be adapted into randomized controlled trials, observational studies, pilot studies, qualitative projects, or systematic reviews depending on the resources available to you.

Most importantly, choose a topic that is specific enough to answer. Instead of researching “the effect of physiotherapy on cerebral palsy,” a question such as “the effect of task-specific balance training compared with progressive resistance training on postural control in ambulatory children with cerebral palsy” gives you a clearly defined population, intervention, comparison, and outcome.

Musculoskeletal and Orthopedic Physiotherapy Research Topics Ideas

Al-Jallad — Fri, 26 Jul 2024 13:01:00 +0000

Last updated: August 2026

Choosing a physiotherapy research topic is easier when you start with a research gap, rather than simply choosing a condition or treatment that interests you.

The 20 musculoskeletal and orthopedic physiotherapy research topics below were selected from gaps and uncertainties identified in recent systematic reviews, meta-analyses and randomized controlled trials (RCTs). Priority was given to questions where the existing evidence remains limited, inconsistent, short-term, poorly standardised, or unable to tell clinicians which intervention works best for which patient.

These are intended as starting points for a physiotherapy thesis, dissertation, research proposal or clinical project. The exact research question should be adapted to your population, available equipment, setting and study design.

Importantly, a recommendation for “more research” does not automatically mean that another small trial of the same intervention is useful. Many areas of musculoskeletal physiotherapy already have substantial evidence that exercise works. Increasingly, the important questions are:

What is the optimal dose?
Which patients respond best?
How should treatment be progressed?
What improves adherence?
Are benefits maintained in the long term?
Which outcomes actually matter to patients?
Can rehabilitation be delivered effectively outside highly controlled research settings?

20 Musculoskeletal and Orthopedic Physiotherapy Research Topic Ideas

Tendinopathy and Shoulder Rehabilitation

1. Which Progressive Loading Strategy Works Best for Patellar Tendinopathy?

Research topic idea:
Comparing Standardised Heavy Slow Resistance With an Individualised Progressive Tendon-Loading Programme for Patellar Tendinopathy: Effects on Pain, Function, Return to Sport and Long-Term Recurrence

Why this is still a research gap:
Exercise is already central to patellar tendinopathy rehabilitation, so another study simply asking whether exercise is effective would add relatively little. A 2026 systematic review and network meta-analysis found no clear clinically meaningful superiority between several progressive loading approaches. The evidence network was sparse, and the authors specifically called for clearer intervention definitions, more comparable populations and consistent follow-up schedules.

A useful study could therefore compare well-defined loading strategies, measure adherence and actual load progression, and include outcomes beyond short-term VISA-P scores, such as return to sport and recurrence at 6–12 months.

Suggested design: RCT with standardised intervention reporting and long-term follow-up.

Evidence basis: Liu et al. Comparative effectiveness of exercise interventions for patellar tendinopathy: a systematic review and network meta-analysis of randomized controlled trials. BMC Sports Science, Medicine and Rehabilitation. 2026. PMID: 42192475. DOI: 10.1186/s13102-026-01743-4.

2. Which Components of Low-Compression Rehabilitation Matter Most in Insertional Achilles Tendinopathy?

Research topic idea:
Determining the Active Components of Low Tendon Compression Rehabilitation for Insertional Achilles Tendinopathy: Heel Lifts, Dorsiflexion Restriction and Stretching Modification

Why this is still a research gap:
A 2025 RCT found that a rehabilitation programme designed to reduce Achilles tendon compression produced greater improvements than a high-compression rehabilitation programme in sport-active people with insertional Achilles tendinopathy.

However, the low-compression programme changed several things simultaneously: ankle dorsiflexion during exercise was limited, calf stretching was removed and heel lifts were used.

The authors specifically recommended research that isolates these components to determine which parts of the programme are responsible for the improvement.

Suggested design: Factorial RCT or multi-arm RCT with at least 6–12 months of follow-up.

Evidence basis: Pringels et al. Effectiveness of reducing tendon compression in the rehabilitation of insertional Achilles tendinopathy: a randomised clinical trial. British Journal of Sports Medicine. 2025. PMID: 40011018. DOI: 10.1136/bjsports-2024-109138.

Rotator Cuff-Related Shoulder Pain

3. What Is the Optimal Frequency and Duration of Exercise for Rotator Cuff-Related Shoulder Pain?

Research topic idea:
Dose-Response Effects of Exercise Frequency and Session Duration in Rotator Cuff-Related Shoulder Pain

Why this is still a research gap:
This is one of the clearest current research gaps.

A systematic review examining exercise according to the FITT principle included 22 RCTs and found some evidence favouring motor-control exercise for disability. However, the review identified no trials directly comparing different exercise frequencies or exercise durations.

Rather than comparing another named shoulder exercise with another named exercise, a carefully designed dose-response RCT could answer a clinically useful question: how much exercise should we actually prescribe?

Suggested design: Multi-arm dose-response RCT comparing different frequencies and/or session durations while keeping exercise type and progression consistent.

4. Can Rotator Cuff Rehabilitation Be Personalised According to Clinical and Psychosocial Characteristics?

Research topic idea:
Individualised Versus Standardised Exercise for Rotator Cuff-Related Shoulder Pain: Can Baseline Physical and Psychosocial Characteristics Predict Treatment Response?

Why this is still a research gap:
The same systematic review found that motor-control programmes may provide slightly better disability outcomes than nonspecific exercise, but it remains unclear whether this occurs because of the exercise itself or because these programmes are more carefully progressed and tailored.

Recent prospective work also suggests that changes in pain-related fear and catastrophising are associated with disability and differ between treatment responders and nonresponders.

A strong next step would be to determine whether incorporating these characteristics into exercise prescription actually improves treatment outcomes.

Suggested design: Stratified RCT or prospective responder study with prespecified treatment-effect moderators.

Evidence basis: Lafrance et al. The Efficacy of Exercise Therapy for Rotator Cuff-Related Shoulder Pain According to the FITT Principle: A Systematic Review With Meta-analyses. Journal of Orthopaedic & Sports Physical Therapy. 2024. PMID: 38848304; and Mears et al. Changes in Pain-Related Fear Predict Shoulder Disability in Rotator Cuff Tendinopathy With Resistance Exercise. Journal of Orthopaedic & Sports Physical Therapy. 2026. PMID: 42538792. DOI: 10.2519/jospt.2026.13563.

5. Exercise Rehabilitation for Adhesive Capsulitis in People With Diabetes

Research topic idea:
Long-Term Effectiveness of Progressive Resistance Exercise for Adhesive Capsulitis in People With Diabetes: A Large Randomized Controlled Trial

Why this is still a research gap:
Diabetes is an important clinical subgroup in adhesive capsulitis, yet intervention evidence specific to this population remains limited.

A 2026 pilot RCT found encouraging improvements in range of motion, pain and disability following an eight-week resistance-band programme, but the study included only 28 participants.

The authors specifically recommended larger randomized trials with longer follow-up.

Suggested design: Adequately powered RCT with 6- and 12-month follow-up, ideally including treatment adherence and diabetes-related variables.

Evidence basis: Moghadasi & Jafari. Effects of resistance-band shoulder exercise on pain, range of motion, and functional disability in diabetic adults with adhesive capsulitis: a pilot randomized controlled trial. BMC Musculoskeletal Disorders. 2026. PMID: 42477667. DOI: 10.1186/s12891-026-10211-6.

Low Back Pain, Sciatica and Neck Pain

6. What Is the Optimal Exercise Dose for Chronic Non-Specific Low Back Pain?

Research topic idea:
A Prospective Dose-Response Trial of Exercise for Chronic Non-Specific Low Back Pain: Frequency, Intensity and Weekly Training Volume

Why this is still a research gap:
A 2024 systematic review with Bayesian network meta-analysis identified a nonlinear relationship between exercise dose and pain across 82 trials involving 5,033 participants.

That is important, but meta-analytic dose-response relationships are generated from differences between existing studies. They are not the same as deliberately randomising similar patients to different doses of the same intervention under controlled conditions.

A prospective dose-response RCT could test whether increasing weekly training volume actually causes better outcomes and where diminishing returns begin.

Suggested design: Multi-arm RCT comparing low-, moderate- and higher-dose versions of the same exercise programme.

Evidence basis: Liang et al. The Best Exercise Modality and Dose for Reducing Pain in Adults With Low Back Pain: A Systematic Review With Model-Based Bayesian Network Meta-analysis. Journal of Orthopaedic & Sports Physical Therapy. 2024. PMID: 38457134. DOI: 10.2519/jospt.2024.12153.

7. Which Active Physiotherapy Programme Works Best for Acute and Subacute Sciatica?

Research topic idea:
Standardised Exercise-Based Physiotherapy Versus Best-Practice Advice for Acute and Subacute Sciatica: Effects on Leg Pain, Function and Progression to Persistent Symptoms

Why this is still a research gap:
Sciatica is common, yet confidence in the comparative effectiveness of nonsurgical treatments remains surprisingly low.

A 2025 systematic review and network meta-analysis concluded that the evidence supporting nonsurgical interventions for acute and subacute sciatica was very low confidence, largely because of bias and imprecision.

A well-powered physiotherapy trial with clearly defined diagnostic criteria, a reproducible intervention and meaningful long-term outcomes could therefore make a substantial contribution.

Suggested design: Pragmatic multicentre RCT with 6–12 month follow-up.

Evidence basis: Zhu et al. Effectiveness of Nonsurgical Interventions for Patients With Acute and Subacute Sciatica: A Systematic Review With Network Meta-Analysis. Journal of Orthopaedic & Sports Physical Therapy. 2025. PMID: 40434940. DOI: 10.2519/jospt.2025.13068.

8. What Is the Optimal Exercise Dose for Chronic Neck Pain?

Research topic idea:
Comparing Different Doses of Strengthening and Motor-Control Exercise for Chronic Non-Specific Neck Pain

Why this is still a research gap:
A 2026 umbrella review synthesising 52 systematic reviews concluded that exercise is beneficial for neck pain, but no single exercise approach was clearly superior.

More importantly, optimal exercise dosage remains unclear, particularly for strengthening programmes.

The next useful question is therefore no longer simply “does strengthening work?”, but how much strengthening is required, how it should progress and whether different patients require different doses.

Suggested design: Dose-response RCT with objectively monitored adherence.

Evidence basis: Amin et al. Overview of reviews for effectiveness of exercise-based interventions for neck pain. Journal of Manual and Manipulative Therapy. 2026. PMID: 42319264. DOI: 10.1080/10669817.2026.2687807.

Rehabilitation Before and After Spine Surgery

9. When Should Active Rehabilitation Begin After Lumbar Disc Surgery?

Research topic idea:
Early Versus Delayed Criterion-Based Active Rehabilitation Following Lumbar Disc Herniation Surgery

Why this is still a research gap:
Physical therapy after lumbar disc surgery appears to improve pain and function, but a 2025 evidence synthesis of 55 RCTs involving 4,311 patients concluded that the optimal timing of rehabilitation remains unresolved.

Important uncertainties also remain around complications and the cost-effectiveness of supervised exercise.

A contemporary trial should therefore compare clearly defined rehabilitation start points rather than simply comparing rehabilitation with no rehabilitation.

Suggested design: Multicentre RCT comparing early criterion-based rehabilitation with later initiation, including complications, return to work and health-economic outcomes.

Evidence basis: Brotis et al. Physical therapies after surgery for lumbar disc herniation—evidence synthesis from 55 randomized controlled trials (RCTs) and a total of 4,311 patients. Brain & Spine. 2025. PMID: 40165991. DOI: 10.1016/j.bas.2025.104238.

10. Which Patients Actually Benefit From Prehabilitation Before Lumbar Spine Surgery?

Research topic idea:
Targeted Prehabilitation Versus Usual Care Before Lumbar Spine Surgery: Identifying Responding Patient Subgroups

Why this is still a research gap:
A 2026 systematic review found minimal overall benefits of preoperative physiotherapy for degenerative lumbar spine disease, but the evidence was very low certainty, interventions were heterogeneous and included studies had high risk of bias.

Importantly, the authors recommended better trials designed to determine which patient subgroups may benefit most.

This makes patient selection a better research question than simply repeating “prehabilitation versus usual care” in an unselected population.

Suggested design: Stratified multicentre RCT examining moderators such as baseline physical capacity, frailty, psychosocial factors or functional limitation.

Evidence basis: The Added Value and the Efficacy of Preoperative Physiotherapy on Degenerative Diseases of the Lumbar Spine: A Systematic Review. Physiotherapy Research International. 2026. PMID: 41995044. DOI: 10.1002/pri.70214.

Knee Osteoarthritis and Joint Replacement

11. Does the Exercise Dose Patients Actually Complete Matter More Than the Dose We Prescribe in Knee Osteoarthritis?

Research topic idea:
Achieved Versus Prescribed Resistance-Exercise Dose in Knee Osteoarthritis and Its Association With Pain, Function and Strength

Why this is still a research gap:
A 2025 systematic review with meta-regression could not identify a relationship between the prescribed total resistance-exercise dose and improvements in pain or function.

However, the review highlighted an important methodological problem: the amount of exercise participants actually complete is often not measured or reported. Studies therefore frequently analyse the prescription rather than the true exposure.

A prospective study using exercise logs, wearable sensors or resistance-training devices could answer whether achieved dose predicts outcomes better than prescribed dose.

Suggested design: Prospective cohort nested within an RCT, or dose-response RCT with objective adherence monitoring.

Evidence basis: de Wit et al. Association Between Prescribed Dosage of Resistance Exercise and Change in Pain and Physical Function in Knee Osteoarthritis: A Systematic Review With Meta-Regression. Musculoskeletal Care. 2025. PMID: 40320557. DOI: 10.1002/msc.70110.

12. How Can Better Exercise Adherence Be Converted Into Better Clinical Outcomes in Knee Osteoarthritis?

Research topic idea:
From Exercise Adherence to Clinical Benefit in Knee Osteoarthritis: Does Individualised Progression Improve Outcomes When Added to a Digital Adherence Intervention?

Why this is still a research gap:
Increasing adherence alone may not be enough.

A recent randomized clinical trial found that adding a mobile app to physiotherapist-prescribed home strengthening approximately doubled the likelihood of complete adherence at 26 weeks, yet better adherence did not translate into superior function.

That raises a more interesting question: does adherence only improve outcomes when the exercise itself is sufficiently progressed, dosed and individualised?

Suggested design: Factorial RCT comparing standard home exercise, adherence support, individually progressed exercise, and the combination.

Evidence basis: Hinman et al. Mobile app to support home exercise adherence in knee osteoarthritis: A randomized clinical trial. Osteoarthritis and Cartilage. 2025. PMID: 41418994. DOI: 10.1016/j.joca.2025.12.012.

13. Can Rehabilitation Be Personalised for Patients at Risk of Poor Recovery After Total Knee Arthroplasty?

Research topic idea:
Targeted Postoperative Rehabilitation for Patients at High Risk of Poor Functional Recovery Following Total Knee Arthroplasty

Why this is still a research gap:
Generic postoperative rehabilitation protocols may not be the most useful area for another trial.

A 2025 systematic review specifically examining patients at risk of poorer outcomes after TKA found insufficient evidence for most rehabilitation approaches, substantial heterogeneity and inconsistent outcome measurement.

The authors called for robust studies of tailored interventions targeting factors associated with poor recovery and better standardisation of outcomes.

Suggested design: Risk-stratified RCT comparing targeted rehabilitation with standard postoperative care.

Evidence basis: Karimijashni et al. Postoperative Rehabilitation Interventions in Patients at Risk of Poorer Outcomes Following Total Knee Arthroplasty: A Systematic Review. Musculoskeletal Care. 2025. PMID: 39853665. DOI: 10.1002/msc.70054.

14. What Are the Long-Term Outcomes of Telerehabilitation After Total Hip Arthroplasty in Older Adults?

Research topic idea:
Hybrid Telerehabilitation Versus Face-to-Face Rehabilitation After Total Hip Arthroplasty in Older Adults: A 12-Month Trial

Why this is still a research gap:
Telerehabilitation after total hip arthroplasty appears capable of producing functional and quality-of-life outcomes comparable to traditional rehabilitation.

However, a 2026 systematic review identified substantial methodological variation and a lack of long-term evidence, and specifically recommended future studies including older patients.

A trial could also determine whether a hybrid model provides the accessibility of telerehabilitation without losing the benefits of periodic face-to-face assessment.

Suggested design: Non-inferiority or superiority RCT with 12-month follow-up and adherence, falls, satisfaction and cost-effectiveness outcomes.

Evidence basis: Farì et al. The potential expected effects of telerehabilitation after total hip arthroplasty: A systematic review. Journal of Back and Musculoskeletal Rehabilitation. 2026. PMID: 42307257. DOI: 10.1177/10538127261457661.

ACL and Sports Knee Rehabilitation

15. Does a Multidimensional Return-to-Sport Assessment Improve Outcomes After ACL Reconstruction?

Research topic idea:
Multidimensional Versus Conventional Return-to-Sport Clearance After ACL Reconstruction: Effects on Return to Performance and Second ACL Injury

Why this is still a research gap:
Return-to-sport decisions remain inconsistent.

Recent evidence suggests that psychological readiness contributes important information that cannot be captured by strength or hop testing alone. At the same time, a 2025 review of return-to-sport testing found substantial variation between protocols, with change-of-direction, agility and biomechanical assessments used much less consistently.

A clinically valuable trial could determine whether a predefined combination of strength, hop performance, movement quality, sport-specific capacity and psychological readiness leads to safer or more successful return to sport than conventional clearance.

Suggested design: Cluster RCT or prospective multicentre trial with second-injury and sustained-return-to-sport outcomes.

Evidence basis: Integrating psychological and physical assessments to obtain optimal return-to-sport outcomes after ACL reconstruction: A systematic review and network meta-analysis. Journal of Sports Sciences. 2025. DOI: 10.1080/02640414.2025.2534224.

16. Do Female Athletes Need Sex-Specific Rehabilitation After ACL Reconstruction?

Research topic idea:
Sex-Specific Rehabilitation and Psychological Support Following ACL Reconstruction: Effects on Return to Sport in Female Athletes

Why this is still a research gap:
A 2026 systematic review and exploratory meta-analysis involving 7,183 athletes found that female athletes had lower odds of returning to sport during the first 12–24 months after ACL reconstruction.

The authors specifically highlighted the need for sex-specific rehabilitation and psychological-support strategies.

Rather than conducting another observational comparison, a future trial could test whether a rehabilitation programme designed around the barriers experienced by female athletes actually changes return-to-sport outcomes.

Suggested design: Multicentre RCT or prospective implementation trial in female athletes.

Evidence basis: Elliott et al. Are There Sex Disparities in Return to Sport After Anterior Cruciate Ligament Reconstruction? A Systematic Review and Exploratory Meta-analysis. American Journal of Sports Medicine. 2026. PMID: 42252835. DOI: 10.1177/03635465261448489.

Ankle Instability and Hamstring Rehabilitation

17. Can Chronic Ankle Instability Rehabilitation Be Matched to the Patient’s Specific Deficit?

Research topic idea:
Deficit-Matched Versus Standard Balance Rehabilitation for Chronic Ankle Instability

Why this is still a research gap:
Chronic ankle instability is not one uniform problem.

A 2026 systematic review and meta-analysis of 58 studies involving 2,097 participants found that different exercise modalities affect different sensorimotor outcomes. Balance training produced broad benefits, whereas other approaches appeared to target more specific deficits. No intervention significantly improved some outcomes, including force sense and eccentric strength.

The logical next question is whether assessing the patient’s dominant deficit first and then matching rehabilitation to that deficit produces better outcomes than giving everyone the same balance programme.

Suggested design: Stratified RCT comparing deficit-matched rehabilitation with standardised balance training.

Evidence basis: Xu et al. Exercise Therapy for Chronic Ankle Instability: Which Modality for Which Deficit? A Systematic Review and Meta-Analysis. Journal of Foot and Ankle Research. 2026. PMID: 41771785. DOI: 10.1002/jfa2.70142.

18. Does Adding Coordination Training Improve Hamstring Rehabilitation?

Research topic idea:
Eccentric Lengthening Exercise With Versus Without Intermuscular Coordination Training Following Hamstring Strain

Why this is still a research gap:
Eccentric lengthening programmes already have meaningful evidence behind them, making another basic eccentric-versus-control study less valuable.

A 2025 systematic review and meta-analysis found benefits from eccentric rehabilitation but identified small samples, substantial protocol heterogeneity and male-dominated study populations. The authors specifically highlighted sex differences and the role of coordination in rehabilitation as priorities for future research.

Suggested design: RCT adding sprint-specific or intermuscular coordination training to an evidence-based eccentric programme, with reinjury and return-to-performance outcomes.

Evidence basis: Abdulridha et al. Comparative effectiveness of rehabilitation protocols for hamstring injuries: A systematic review and meta-analysis. Journal of Bodywork and Movement Therapies. 2025. PMID: 40954668. DOI: 10.1016/j.jbmt.2025.06.030.

Scoliosis Rehabilitation

19. What Is the Optimal Dose of Physiotherapeutic Scoliosis-Specific Exercise?

Research topic idea:
Dose-Response and Long-Term Effects of Physiotherapeutic Scoliosis-Specific Exercise in Adolescent Idiopathic Scoliosis

Why this is still a research gap:
The important question is no longer simply whether PSSE can produce benefits.

A 2025 systematic review and meta-analysis of 18 RCTs involving 1,014 adolescents found improvements in Cobb angle, angle of trunk rotation and quality of life. Higher-frequency programmes appeared more effective.

However, the authors specifically called for further RCTs to establish the optimal exercise dose and identify factors that influence treatment response.

Future trials should therefore examine frequency, session duration, adherence, curve characteristics and longer-term outcomes rather than comparing PSSE with no exercise alone.

Suggested design: Multicentre dose-response RCT stratified by curve pattern and severity, with follow-up extending beyond treatment completion.

Evidence basis: Jia et al. Effectiveness of physical therapeutic scoliosis exercise (PSSE) intervention for adolescent idiopathic scoliosis: a systematic review and meta-analysis. BMC Musculoskeletal Disorders. 2025. PMID: 41073947. DOI: 10.1186/s12891-025-09218-2.

Foot Rehabilitation

20. Should Flexible Flatfoot Rehabilitation Target the Entire Lower-Limb Kinetic Chain?

Research topic idea:
Comprehensive Lower-Limb Strengthening Versus Short-Foot Exercise Alone in Adults With Symptomatic Flexible Flatfoot

Why this is still a research gap:
Short-foot exercise has already been studied repeatedly, so simply comparing it with no exercise is becoming less informative.

A 2024 network meta-analysis of RCTs suggested potential advantages from interventions incorporating hip, lower-limb and posterior tibial strengthening. However, only 11 studies with 335 participants were available, some networks contained very few trials, intervention durations varied substantially and the authors highlighted small samples and imprecise estimates.

They recommended further high-quality RCTs to refine comprehensive strengthening approaches. Important details such as the optimal loading angle, speed, repetitions and treatment duration for posterior tibial strengthening also remain unresolved.

A future study should prioritise symptomatic patients and patient-important outcomes such as pain, walking ability and function, rather than relying mainly on arch measurements.

Suggested design: RCT comparing short-foot exercise with a comprehensive hip-knee-foot strengthening programme, with at least 6–12 months of follow-up.

Evidence basis: Jia et al. Comparing the efficacy of exercise therapy on adult flexible flatfoot individuals through a network meta-analysis of randomized controlled trials. Scientific Reports. 2024. PMID: 39261538. DOI: 10.1038/s41598-024-72149-w.

Types of Research in Musculoskeletal and Orthopedic Physiotherapy

The best research design depends on the question being asked. A randomized controlled trial is powerful for evaluating the causal effect of an intervention, but it is not automatically the best design for questions about prognosis, diagnosis, patient experiences or natural history.

Interventional Research

Interventional studies test whether changing treatment changes an outcome. These include randomized controlled trials, pragmatic trials, feasibility studies and pilot trials.

Example: Comparing two different exercise doses for chronic low back pain.

Observational and Prognostic Research

These studies investigate associations or follow patients over time without assigning the exposure or treatment.

They are useful for identifying predictors of recovery, recurrence or treatment response.

Example: Determining whether baseline quadriceps strength, psychological readiness and movement quality predict return to sport following ACL reconstruction.

Diagnostic and Measurement Research

These studies investigate the accuracy, validity, reliability or responsiveness of clinical tests and outcome measures.

Example: Evaluating the diagnostic accuracy of a clinical test for gluteal tendinopathy or the responsiveness of a patient-reported outcome measure during rehabilitation.

Biomechanical Research

Biomechanical studies investigate movement, joint loading, muscle activity, force production and other mechanical characteristics.

Biomechanics can be incorporated into experimental, cross-sectional or longitudinal study designs.

Example: Examining whether different rehabilitation strategies alter landing biomechanics after ACL reconstruction.

Qualitative Research

Qualitative research explores experiences, beliefs, barriers, expectations and decision-making.

It can be particularly useful when an intervention is known to work but implementation or adherence remains poor.

Example: Exploring why people with knee osteoarthritis discontinue long-term exercise despite receiving physiotherapy.

Systematic Reviews and Meta-Analyses

Evidence syntheses bring together existing studies to answer a focused research question and identify remaining uncertainties.

A new systematic review is most useful when the literature has changed enough to justify an update or when an important question has not previously been synthesised.

Example: Comparing different methods of exercise progression following rotator cuff-related shoulder pain.

How to Turn One of These Ideas Into a Thesis Question

A good research topic is only the starting point. Before committing to it:

Search the most recent evidence. A research gap identified two years ago may already have been addressed.
Define the population precisely. “Shoulder pain” is much less useful than “adults with rotator cuff-related shoulder pain.”
Define the intervention in enough detail that it can be reproduced.
Choose a meaningful comparator. Another active treatment may be more useful than a no-treatment control.
Prioritise patient-important outcomes. Pain, function, participation, recurrence and quality of life are often more meaningful than isolated biomechanical changes.
Include adequate follow-up. Many musculoskeletal interventions have already demonstrated short-term effects while long-term outcomes remain uncertain.
Measure adherence and actual treatment exposure whenever possible.
Check feasibility. The best student project is not necessarily the most complicated question; it is the strongest question that can realistically be answered with the available time, population and equipment.

Before You Finalise Your Research Topic

A research question should be considered provisional until you have checked whether newer studies have already answered it.

Search recent systematic reviews, randomized controlled trials and physiotherapy research in PhysioKeys before finalising your protocol. This can also help you identify appropriate outcome measures, intervention parameters and references for your literature review.

Research gaps change as new evidence is published, so this list will continue to be updated as the musculoskeletal and orthopedic physiotherapy literature evolves.

20 Sports Physiotherapy Research Topic Ideas

Al-Jallad — Tue, 14 Feb 2023 11:24:23 +0000

Sports physiotherapy is an area of physical therapy that focuses on the prevention and treatment of injuries related to sports and exercise. It is a specialized field of physiotherapy that requires a comprehensive understanding of the physical demands of sport and exercise.

Research in the field of sports physiotherapy is important to identify the most effective ways to prevent and treat sports injuries as well as injury mechanism.

This article provides some research topics related to sports physiotherapy that can be used as a starting point for exploring this area of research further.

We can divide sports research into 4 areas:

Injury prevention
Rehabilitation after Injury
Return to play.
Injury mechanism

Injury Prevention

Preventing sports injuries from occurring in the first place is one of the most important goals of sports physiotherapy. By proactively addressing risk factors and addressing underlying problems before they lead to injury, physiotherapists can help their patients stay healthy, active, and performing at their best.

There are a number of strategies that can be used to prevent sports injuries, including:

Strength and conditioning programs to improve overall fitness, reduce the risk of injury, and enhance performance.
Biomechanical assessments to identify and address any underlying mechanical problems that may be contributing to injury.
Correction of training errors, such as overtraining or inadequate recovery, to reduce the risk of overuse injuries.
Proper warm-up and cool-down techniques to prepare the body for physical activity and reduce the risk of injury.
Use of appropriate equipment, such as well-fitting shoes and properly sized athletic gear, to reduce the risk of injury.

By incorporating these and other injury prevention strategies into their treatment plans, physiotherapists can help their patients stay healthy and active, and reduce the risk of injury. Additionally, by conducting research in the area of injury prevention, physiotherapists can contribute to the advancement of the field and help to identify new and innovative strategies for injury prevention.

Examples of injury prevention research topics include:

The impact of strength and conditioning programs on injury risk in athletes.
The effectiveness of warm-up and cool-down routines in reducing the risk of injury in athletes.
The impact of proper equipment use on injury risk in athletes.
The role of biomechanical assessments in reducing the risk of injury in athletes.

Rehabilitation after Injury

One of the most important aspects of sports physiotherapy is the rehabilitation of athletes after injury. The goal of rehabilitation is to help athletes recover from their injuries, regain their physical function, and return to their sport as safely and quickly as possible.

To achieve these goals, physiotherapists use a range of techniques and interventions, including exercise therapy, manual therapy, and the use of assistive devices such as braces and crutches. The specific rehabilitation plan will depend on the nature and severity of the injury, as well as the individual needs and goals of the athlete.

In addition to helping athletes recover from injury, rehabilitation also plays a critical role in reducing the risk of reinjury. By addressing any underlying problems and improving physical function, physiotherapists can help to reduce the risk of future injury and improve the long-term health and performance of their patients.

Examples of rehabilitation research topics include:

The effectiveness of different exercise interventions for the rehabilitation of specific types of sports injuries.
The role of manual therapy in the rehabilitation of sports injuries.
The impact of rehabilitation programs on the risk of reinjury in athletes.
The use of assistive devices in the rehabilitation of sports injuries.

Return to Play

Returning to play after an injury is a key goal for many athletes, and a critical aspect of sports physiotherapy. The process of returning to play involves a gradual progression from rest and rehabilitation to a return to full competition, and is guided by a number of principles and considerations, including:

The nature and severity of the injury.
The athlete’s physical function and readiness to return to play.
The athlete’s goals and expectations for their return to play.
The potential risks and benefits of returning to play.

The return to play process is typically managed by a multidisciplinary team, including physiotherapists, physicians, and other healthcare professionals. The team works together to develop a safe and effective plan for the athlete’s return to play, and to monitor their progress and adjust the plan as needed.

Examples of return to play research topics include:

The impact of different rehabilitation interventions on the return to play process.
The role of medical clearance in the return to play process.
The impact of injury on the psychological readiness of athletes to return to play.
The impact of previous injury on the risk of future injury in athletes.

Injury Mechanism

In addition to exploring the various topics related to sports injury prevention, rehabilitation, and return to play, it is also important to have a thorough understanding of injury mechanisms. This refers to the underlying causes of sports injuries, such as biomechanical factors, training errors, and external factors such as playing surface and equipment.

By understanding the mechanisms of injury, physiotherapists can better identify and address the root cause of an injury, leading to more effective treatment and injury prevention strategies. For example, if a specific type of injury is found to be caused by poor biomechanics during running, a physiotherapist could focus on correcting these mechanics through targeted exercises and training.

In order to fully understand injury mechanisms, it is important to consider multiple factors, including an athlete’s age, level of play, and sport-specific demands. By conducting research in this area, physiotherapists can contribute to a growing body of knowledge that can be used to improve injury prevention and treatment practices in sports.

Some examples of injury mechanism research topics include:

The impact of foot mechanics on the risk of lower limb injury in athletes.
The role of fatigue in the development of musculoskeletal injuries in athletes.
The impact of playing surface and equipment on the risk of injury in athletes.
The impact of training volume and intensity on the risk of overuse injuries in athletes.

Neuro Physiotherapy Research Topics: 20 Evidence-Based Thesis Ideas for 2026

Last updated: August 2026

Choosing a good neuro physiotherapy research topic should begin with an unanswered clinical question, not simply a neurological condition or treatment that sounds interesting.

Neuro physiotherapy—also called neurological physical therapy or neurorehabilitation—covers rehabilitation of movement, mobility, balance, physical capacity, participation and function in people with neurological conditions.

The research ideas below were selected from gaps and uncertainties identified in recent systematic reviews, meta-analyses and randomized controlled trials (RCTs). Priority was given to questions that could meaningfully improve physiotherapy practice.

Many broad questions such as “does exercise help after stroke?” or “is physical activity beneficial in Parkinson’s disease?” already have substantial evidence behind them. More useful research questions now often concern:

the optimal rehabilitation dose;
which patients respond best;
when treatment should begin;
how rehabilitation should progress;
whether gains transfer to everyday life;
whether benefits persist after treatment stops;
adherence and actual treatment exposure;
rehabilitation in under-represented patient groups;
home and telerehabilitation models;
participation, falls and quality of life rather than impairment alone.

The following topics can be adapted for a physiotherapy thesis, dissertation, research proposal or clinical project.

Stroke Rehabilitation Research Topics

1. Who Benefits Most From High-Dose Upper-Limb Rehabilitation After Stroke?

Research topic idea:
High-Dose Task-Oriented Upper-Limb Rehabilitation After Stroke: Identifying the Dose and Patient Characteristics Associated With Clinically Important Recovery

Why this is still a research gap:
The general principle that repetitive, task-oriented rehabilitation can improve upper-limb recovery is well established. The unresolved question is how much additional practice is necessary and which patients are most likely to respond.

A 2026 systematic review found only four eligible trials directly comparing meaningfully different durations of otherwise similar upper-limb rehabilitation. Improvements became more apparent when rehabilitation duration was increased substantially, but the certainty of evidence remained low.

Another systematic review found that only about 6% of the included rehabilitation studies investigated factors that might predict treatment response. Corticospinal tract integrity, preserved arm motor function and other patient characteristics may influence recovery, but responder research remains limited.

Rather than another small trial showing that upper-limb exercise works, a better study would investigate dose × patient characteristics × real-world arm use.

Suggested design: Stratified dose-response RCT with prespecified responder analysis and accelerometer-measured real-world arm use.

Evidence basis:
Patel et al. Does more rehabilitation lead to better upper limb outcomes after stroke? A systematic review. Frontiers in Rehabilitation Sciences. 2026. PMID: 41847569.

Salvalaggio et al. Predictive factors and dose-response effect of rehabilitation for upper limb induced recovery after stroke: systematic review with proportional meta-analyses. Physiotherapy Journal. 2024. PMID: 39395360.

2. What Is the Optimal Exercise Dose for Improving Balance After Stroke?

Research topic idea:
Prospective Validation of a Dose-Response Exercise Prescription for Balance Recovery After Stroke

Why this is still a research gap:
Exercise improves post-stroke balance, but that does not mean that progressively increasing the exercise dose will always produce greater improvement.

A 2026 Bayesian dose-response network meta-analysis of 42 RCTs suggested a non-linear relationship between exercise dose and balance. The modelling identified a minimum dose associated with improvement and suggested that gains may eventually plateau or decline at higher doses.

These findings are clinically interesting, but they are derived from differences between existing trials rather than a trial deliberately randomising similar participants to different doses of the same programme.

The next step is therefore to prospectively test the dose-response relationship while measuring fatigue, adherence, falls and baseline impairment.

Suggested design: Multi-arm dose-response RCT comparing low-, moderate- and higher-dose programmes with identical exercise content.

Evidence basis:
Optimal exercise prescription for balance after stroke: a Bayesian dose-response network meta-analysis. Frontiers in Neurology. 2026. PMID: 42051770.

3. Which Dual-Task Training Strategy Best Transfers to Real-World Walking After Stroke?

Research topic idea:
Motor-Walking Versus Cognitive-Balance Dual-Task Training After Stroke: Effects on Community Mobility, Falls and Retained Dual-Task Performance

Why this is still a research gap:
Dual-task rehabilitation has become increasingly common after stroke.

Recent network meta-analysis suggests that different forms of dual-task training may affect different outcomes: motor-walking combinations appear particularly promising for several gait outcomes, while cognitive-balance combinations may perform well for functional mobility.

However, earlier trial-sequential analysis found the certainty of evidence to be very low to low for several outcomes and indicated that larger trials were required.

Most importantly, improvements in a Berg Balance Scale or 10-Metre Walk Test do not necessarily demonstrate that somebody can safely walk through a busy community environment while talking, navigating obstacles or making decisions.

A stronger trial should therefore prioritise ecological dual-task performance, falls and retention of improvement.

Suggested design: Multicentre RCT with instrumented community walking assessment and 6–12 month falls follow-up.

Evidence basis:
Zhao et al. Effects of dual-task training on walking and balance in stroke patients: A systematic review and network meta-analysis. Clinical Rehabilitation. 2025. PMID: 41269895.

Zhang et al. Cognitive-motor dual-task training on gait and balance in stroke patients: meta-analytic report and trial sequential analysis of randomized clinical trials. Journal of NeuroEngineering and Rehabilitation. 2024. PMID: 39716165.

4. Which Stroke Survivors Benefit Most From High-Intensity Exercise?

Research topic idea:
Personalising High-Intensity Exercise After Stroke According to Recovery Stage, Walking Ability and Cardiovascular Capacity

Why this is still a research gap:
High-intensity exercise is increasingly used in stroke rehabilitation, but its effects are not uniform across outcomes.

A 2025 systematic review of relatively large, higher-quality RCTs found benefits for six-minute walking distance and balance, while effects on gait speed, Timed Up and Go, cognition and measured cardiorespiratory fitness were less clear.

This suggests that “high intensity” should not be treated as one universally effective prescription.

A clinically useful next question is who should receive high-intensity training, at what stage after stroke, and what physiological target should actually define intensity?

Suggested design: Stratified pragmatic RCT comparing personalised high-intensity training with conventional moderate-intensity rehabilitation.

Evidence basis:
Li et al. Effects of high-intensity exercise on rehabilitation of patients after stroke: a systematic review and meta-analysis of randomized controlled trials with high quality. Frontiers in Neurology. 2025. PMID: 40843265.

5. Can Therapist-Led Group Telerehabilitation Improve Long-Term Participation After Stroke?

Research topic idea:
Therapist-Led Group Telerehabilitation Versus Independent Home Exercise in Chronic Stroke: Effects on Mobility, Participation, Falls, Adherence and Cost

Why this is still a research gap:
Telerehabilitation is no longer a completely experimental concept, but how it should be delivered remains important.

A small 2026 RCT analysis found that real-time group telerehabilitation led by physiotherapists produced modestly greater improvements in balance and mobility than self-directed exercise in chronic stroke.

Only 35 participants were included, however.

A larger pragmatic study could determine whether therapist-led groups improve more meaningful outcomes such as community participation, exercise adherence, falls and healthcare utilisation, and whether the additional therapist time is cost-effective.

Suggested design: Multicentre pragmatic RCT with economic evaluation.

Evidence basis:
Ro et al. Predictors of Functional Improvement in Patients with Chronic Stroke Participating in Group-Based Telerehabilitation: A Post-hoc Analysis of a Randomized Controlled Trial. NeuroRehabilitation. 2026. PMID: 42228382.

Parkinson’s Disease Physiotherapy Research Topics

6. Should Exercise for Parkinson’s Disease Be Matched to Disease Stage and Predominant Motor Deficit?

Research topic idea:
Personalised Versus Standardised Exercise Rehabilitation in Parkinson’s Disease Based on Disease Stage and Predominant Motor Impairment

Why this is still a research gap:
Exercise clearly has an important role in Parkinson’s disease. The more interesting question is no longer simply whether exercise works.

A major Cochrane network meta-analysis included 154 RCTs involving 7,837 participants and found benefits from many different exercise types, with relatively little evidence that one type is universally superior.

However, participants were predominantly people with mild-to-moderate Parkinson’s disease without major cognitive impairment.

That leaves an important clinical question: instead of selecting one “best” form of exercise for everybody, would outcomes improve if exercise were matched to the individual’s dominant problem—such as freezing, balance impairment, reduced aerobic capacity or weakness—and disease stage?

Suggested design: Stratified RCT comparing impairment-matched rehabilitation with a standard multimodal programme.

Evidence basis:
Ernst et al. Physical exercise for people with Parkinson’s disease: a systematic review and network meta-analysis. Cochrane Database of Systematic Reviews. 2024. PMID: 38588457.

7. Which Cueing Strategy Produces Lasting Improvements in Freezing and Community Walking in Parkinson’s Disease?

Research topic idea:
Personalised Auditory, Visual and Somatosensory Cueing for Parkinsonian Gait: Effects on Freezing, Community Mobility and Long-Term Carryover

Why this is still a research gap:
Auditory cueing combined with walking training appears capable of improving walking speed.

A systematic review found an average improvement in walking speed compared with walking training alone, but evidence was low quality. Effects on mobility, balance, fear of falling, freezing and maintenance after the intervention remained uncertain.

This is particularly important because successful cueing in a supervised corridor does not guarantee successful cue use when someone freezes while turning, crossing a doorway or walking through a crowded environment.

Research should therefore move toward patient-specific cue selection and real-world carryover.

Suggested design: Crossover or parallel-group RCT stratified by freezing phenotype, followed by home/community monitoring.

Evidence basis:

8. What Is the Best Telerehabilitation Model for Parkinson’s Disease?

Research topic idea:
Hybrid, Videoconference and Digital Exercise Rehabilitation for Parkinson’s Disease: Which Delivery Model Works Best and for Whom?

Why this is still a research gap:
A 2025 systematic review and meta-analysis of 18 studies involving 731 people found that telerehabilitation generally produced outcomes comparable with control conditions for gait, balance and functional mobility and showed an advantage for quality of life.

But “telerehabilitation” included very different interventions, including video-based treatment and remote exergaming.

Rather than continuing to ask whether remote rehabilitation works at all, the more clinically useful question is which remote-delivery model provides the best balance between effectiveness, adherence, accessibility, safety and therapist input.

Long-term outcomes in people with more advanced disease are also important.

Suggested design: Pragmatic three-arm trial comparing hybrid, synchronous remote and predominantly self-directed digital rehabilitation.

Evidence basis:

Multiple Sclerosis Physiotherapy Research Topics

9. What Is the Optimal Exercise Dose for Managing Multiple Sclerosis-Related Fatigue?

Research topic idea:
Dose-Response Effects of Aerobic and Resistance Exercise on Fatigue in Multiple Sclerosis

Why this is still a research gap:
Exercise can reduce fatigue in multiple sclerosis, but precise prescription remains difficult.

A 2026 umbrella review synthesised 35 systematic reviews and meta-analyses. Cardiorespiratory exercise had the most consistent evidence, while resistance exercise also showed benefit but greater heterogeneity.

Importantly, reporting of frequency, intensity, time, type, volume and progression was incomplete across the literature, preventing confident modality-specific prescriptions.

Another study asking “does exercise improve MS fatigue?” is therefore unlikely to add much. A better question is what dose produces useful fatigue improvement without causing poor adherence or excessive symptom burden?

Suggested design: Dose-response RCT with objectively monitored achieved exercise dose.

Evidence basis:
Rubio-Arias et al. Structured exercise training for fatigue management in multiple sclerosis: an umbrella review of systematic reviews and meta-analyses. Archives of Physical Medicine and Rehabilitation. 2026. PMID: 42532214.

10. Which Exercise Prescription Best Reduces Spasticity in Multiple Sclerosis?

Research topic idea:
Exercise Dose, Modality and Clinically Meaningful Spasticity Outcomes in Ambulatory People With Multiple Sclerosis

Why this is still a research gap:
This is a much stronger version of the older generic topic “physiotherapy for spasticity.”

A 2026 systematic review identified 13 RCTs evaluating exercise and spasticity in ambulatory people with MS. Exercise was generally associated with reductions in spasticity, with flexibility and range-of-motion components showing relatively consistent findings.

However, exercise protocols differed substantially, treatment dose was incompletely reported, and some commonly used spasticity measures may not be sensitive enough to capture clinically meaningful change.

The research gap therefore involves both what to prescribe and how treatment success should be measured.

Suggested design: RCT comparing clearly defined exercise programmes using both impairment measures and patient-important functional outcomes.

Evidence basis:
González-Mingorance et al. Effects of physical exercise on spasticity in people with multiple sclerosis: A systematic review. Physiotherapy Journal. 2026. PMID: 42424757.

11. How Should Tele-Exercise Be Optimised for Long-Term Multiple Sclerosis Rehabilitation?

Research topic idea:
Hybrid Versus Fully Remote Exercise Rehabilitation in Multiple Sclerosis: Long-Term Effects on Fatigue, Mobility, Participation and Adherence

Why this is still a research gap:
A systematic review and meta-analysis found beneficial effects of tele-exercise on fatigue, depression, physical health and quality of life.

The authors nevertheless identified the need to optimise tele-exercise protocols, investigate longer-term effects and explore integration with other telemedicine approaches.

This is an important distinction: showing that an eight- or twelve-week remote programme can work is not the same as determining whether people can maintain meaningful exercise participation for a year.

Suggested design: Pragmatic RCT with at least 12 months of follow-up and economic/adherence analysis.

Evidence basis:
Najafi et al. Tele-exercise in multiple sclerosis: Systematic review and meta-analysis of effects on fatigue, depression, and overall health. Multiple Sclerosis and Related Disorders. 2025. PMID: 39709696.

Spinal Cord Injury Rehabilitation Research Topics

12. Does Functional Electrical Stimulation Add Meaningful Benefit to Locomotor Training After Incomplete SCI?

Research topic idea:
Dose-Matched Functional Electrical Stimulation-Assisted Versus Conventional Locomotor Training After Motor-Incomplete Spinal Cord Injury

Why this is still a research gap:
Functional electrical stimulation is theoretically attractive because it can increase muscle activation during locomotor training.

However, a recent systematic review and meta-analysis did not find clear additional improvements in walking speed or endurance from FES-assisted locomotor training compared with other locomotor approaches.

The literature included relatively few RCTs and considerable variation in both training dose and electrical-stimulation parameters.

The authors specifically recommended better standardisation and reporting.

This makes a tightly controlled dose-matched comparison considerably more useful than another uncontrolled FES study.

Suggested design: Multicentre RCT with matched locomotor-training dose and standardised FES parameters.

Evidence basis:
Unger et al. Effectiveness of Functional Electrical Stimulation Assisted Locomotor Training on walking Outcomes Following Incomplete Spinal Cord Injury: Systematic Review and Meta-Analysis. Neurorehabilitation and Neural Repair. 2025. PMID: 41362083.

13. What Is the Optimal Dose of Exoskeleton Gait Training After Spinal Cord Injury?

Research topic idea:
Goal-Specific Exoskeleton Gait-Training Dose After Spinal Cord Injury: Functional Walking Versus Cardiovascular Rehabilitation

Why this is still a research gap:
Exoskeleton research has expanded rapidly, but training protocols remain highly heterogeneous.

A systematic review examining dose and dosage identified substantial variation in session duration, frequency, total treatment duration and clinical indications.

The review proposed practical dose ranges but also concluded that structured clinical translation studies using standardised methods and common therapeutic outcomes are needed.

Another important issue is that the optimal programme may differ depending on whether the goal is walking recovery, balance, cardiovascular conditioning or participation.

Suggested design: Goal-stratified pragmatic RCT comparing exoskeleton training with dose-matched conventional gait rehabilitation.

Evidence basis:
Nepomuceno et al. Exoskeleton-based exercises for overground gait and balance rehabilitation in spinal cord injury: a systematic review of dose and dosage parameters. Journal of NeuroEngineering and Rehabilitation. 2024. PMID: 38705999.

14. Can Long-Term FES Cycling or Rowing Improve Cardiometabolic Health After Spinal Cord Injury?

Research topic idea:
Long-Term Functional Electrical Stimulation-Assisted Exercise After Spinal Cord Injury: Effects on Aerobic Capacity, Respiratory Function and Cardiometabolic Health

Why this is still a research gap:
FES-assisted cycling and rowing may have benefits beyond neurological motor recovery.

A 2025 systematic review and meta-analysis found improvements in some respiratory outcomes from FES and increased aerobic capacity when FES was combined with cycling or rowing.

However, included studies were heterogeneous and sample sizes for several outcomes were small.

A clinically important next step would be to determine whether these short-term physiological changes result in sustained cardiometabolic benefit, greater physical activity and improved participation.

Suggested design: Long-term RCT or prospective comparative trial lasting 6–12 months.

Evidence basis:
Xiangli et al. Efficacy of functional electrical stimulation alone and as an adjunct to exercise for improving respiratory function and aerobic capacity in spinal cord injury: a systematic review and meta-analysis. Frontiers in Rehabilitation Sciences. 2025. PMID: 40820989.

Traumatic Brain Injury and Concussion Research Topics

15. When and How Intensively Should Active Rehabilitation Begin After Mild Traumatic Brain Injury?

Research topic idea:
Early Active Rehabilitation After Mild Traumatic Brain Injury: Determining the Optimal Start Time and Exercise Intensity

Why this is still a research gap:
Extended complete rest after concussion is increasingly being replaced by an active-rehabilitation approach.

A systematic review found that individualised active rehabilitation initiated within the first month after mild TBI appeared safe and frequently shortened symptom recovery.

However, the included studies used very different exercise modalities, durations and intensities.

The authors concluded that there is still no consensus on the specific intervention protocol required for routine clinical implementation.

That makes timing, intensity and progression far more useful research questions than another simple active-versus-rest comparison.

Suggested design: Factorial or multi-arm RCT varying start time and symptom-limited aerobic intensity.

Evidence basis:
Coman et al. Active Rehabilitation Following Acute Mild Traumatic Brain Injury: A Systematic Review. Physiotherapy Canada. 2024. PMID: 40959158.

16. Should Vestibular Rehabilitation After Concussion Be Progressed According to Symptoms Rather Than a Fixed Dose?

Research topic idea:
Symptom-Guided Versus Fixed-Dose Vestibular Rehabilitation After Mild Traumatic Brain Injury

Why this is still a research gap:
Vestibular rehabilitation can improve dizziness and post-concussion symptoms, but the optimal prescription remains uncertain.

A 2026 randomized clinical trial compared different exercise intensities and frequencies and found no clear advantage for one fixed dose over another. The authors concluded that treatment dose could reasonably be individualised around goals and symptom burden.

Earlier systematic review evidence also found improvements in perceived dizziness, but benefits were less clear at longer follow-up and evidence for return to sport or function remained uncertain.

The logical next question is therefore whether a structured symptom-guided progression algorithm performs better than giving everyone the same vestibular-exercise dose.

Suggested design: RCT comparing symptom-guided progression with a standardised fixed protocol.

Evidence basis:
Sparto et al. Effect of Dose of Targeted Rehabilitation Exercises for Vestibular (T-REV) Impairments following mTBI on Dizziness Handicap: A Randomized Clinical Trial. Journal of Neurologic Physical Therapy. 2026. PMID: 41576285.

Functional Neurological Disorder Research Topics

17. What Is the Optimal Outpatient Physiotherapy Programme for Motor Functional Neurological Disorder?

Research topic idea:
Dose, Content and Outcome Measurement of Specialist Physiotherapy for Motor Functional Neurological Disorder

Why this is still a research gap:
Physiotherapy for motor FND commonly includes education, retraining movement with redirected attention and strategies for symptom management.

A 2026 scoping review found that many reported interventions broadly aligned with consensus recommendations, but the way treatment was delivered varied enormously—from intensive daily programmes to sessions only twice per month.

Outcome measurement was also heavily weighted toward body function rather than broader activity and participation.

The review specifically identified the need to compare intervention modes and determine optimal treatment parameters.

Suggested design: Multicentre pragmatic RCT or adaptive trial comparing different treatment intensities, accompanied by mixed-methods evaluation.

Evidence basis:
Gann et al. Outpatient Occupational Therapy, Physiotherapy, and Speech Language Pathology Interventions for People with Functional Neurologic Disorder: A Scoping Review. NeuroRehabilitation. 2026. PMID: 42089740.

Cerebral Palsy Neurorehabilitation Research Topics

18. Does the Scheduling of Intensive Therapy Matter in Bilateral Cerebral Palsy?

Research topic idea:
Massed Versus Distributed HABIT-ILE in Bilateral Cerebral Palsy: Effects on Motor Function, Participation, Family Burden and Long-Term Retention

Why this is still a research gap:
Intensive motor-learning programmes can require dozens of hours of rehabilitation over relatively short periods, creating substantial practical challenges for families.

A 2026 randomized study compared 90 hours of HABIT-ILE delivered either intensively over three weeks or distributed across 15 weeks.

Both schedules produced improvements and neither schedule was clearly superior.

That is clinically useful, but only 21 children participated. A larger study should go beyond motor outcomes and investigate family burden, participation, school attendance, cost and retention of gains.

Suggested design: Multicentre non-inferiority RCT with family-centred and participation outcomes.

Evidence basis:
Sienko et al. The Impact of Dosing Schedule on the Efficacy of Hand-Arm Bimanual Intensive Therapy Including the Lower Extremities (HABIT-ILE) in Children With Bilateral Cerebral Palsy. Neurorehabilitation and Neural Repair. 2026. PMID: 42057736.

19. Does Intensive Goal-Oriented Strengthening Produce Lasting Benefits in Adults With Cerebral Palsy?

Research topic idea:
Intensive Goal-Oriented Strengthening in Adults With Cerebral Palsy: Long-Term Effects on Mobility, Fatigue, Participation and Healthy Ageing

Why this is still a research gap:
Cerebral palsy rehabilitation research is heavily weighted toward childhood, even though the condition is lifelong.

A 2026 retrospective study of 66 ambulatory adults found encouraging short-term improvements following a four-week intensive goal-oriented strengthening programme, including improvements in walking, goal performance, strength and fatigue.

Because the study was uncontrolled and only examined short-term outcomes, it cannot establish treatment efficacy.

This creates a clear opportunity for a higher-quality trial examining whether intensive rehabilitation has durable benefits in adult CP, particularly as mobility demands and secondary musculoskeletal problems change with age.

Suggested design: RCT with 6–12 month follow-up and participation-focused outcomes.

Evidence basis:
Mathevon et al. Intensive Therapy in Adults with Cerebral Palsy? Yes, They Can! A Retrospective Study on Short-Term Functional Outcomes of an Intensive Goal-Oriented Strengthening Program. NeuroRehabilitation. 2026. PMID: 42530921.

Cerebellar Ataxia Physiotherapy Research Topics

20. What Is the Optimal Multicomponent Physiotherapy Programme for Degenerative Cerebellar Ataxia?

Research topic idea:
Dose and Long-Term Effectiveness of Multicomponent Physiotherapy for Degenerative Cerebellar Ataxia

Why this is still a research gap:
A systematic review and meta-analysis found potentially beneficial effects from multicomponent physiotherapy, balance training and aerobic exercise in degenerative cerebellar ataxia.

However, the certainty of evidence was low, studies had substantial risk of bias and heterogeneity, participant numbers were generally small, and treatment periods were often short.

Different forms of hereditary and degenerative ataxia were also frequently grouped together.

A high-quality study should therefore investigate a well-defined multicomponent programme, optimal dose, disease subtype and long-term functional outcomes, rather than relying only on short-term changes in ataxia severity scales.

Suggested design: Multicentre RCT stratified by ataxia subtype with 6–12 month follow-up.

Evidence basis:
Effects of physiotherapy on degenerative cerebellar ataxia: a systematic review and meta-analysis. Frontiers in Neurology. 2024. PMID: 39866519.

What Types of Research Work Well in Neuro Physiotherapy?

The strongest design depends on the research question.

Dose-Response Trials

Useful when an intervention is already known to help but the appropriate frequency, intensity or total amount is uncertain.

Example: Comparing different doses of upper-limb task practice after stroke.

Stratified or Personalised Rehabilitation Trials

Useful when people with the same diagnosis respond differently to rehabilitation.

Example: Determining whether people with Parkinson’s disease should receive different exercise programmes according to their predominant gait, balance or strength impairment.

Pragmatic Randomized Controlled Trials

Useful for determining whether an intervention works under real clinical conditions rather than only under tightly controlled laboratory conditions.

Example: Comparing group telerehabilitation with conventional community stroke rehabilitation.

Prognostic and Responder Studies

Useful for identifying who is likely to recover or benefit from a particular intervention.

Example: Identifying clinical predictors of upper-limb response to intensive stroke rehabilitation.

Implementation and Health-Service Research

Useful when an intervention appears effective but is difficult to deliver in routine practice.

Example: Evaluating the cost, adherence and accessibility of hybrid rehabilitation in Parkinson’s disease.

Qualitative and Mixed-Methods Research

Useful for understanding experiences, barriers, treatment acceptability and participation.

Example: Exploring why people with neurological conditions stop exercising after completing formal rehabilitation.

Systematic Reviews and Meta-Analyses

Useful when evidence exists but has not been adequately synthesised.

Before beginning another systematic review, check whether a recent high-quality review already answers the question.

How to Turn One of These Ideas Into a Neuro Physiotherapy Thesis

Before choosing your final question:

Define the neurological population precisely.
“Stroke” may be too broad. Consider recovery stage, severity, walking status or upper-limb impairment.
Specify the rehabilitation intervention.
Describe frequency, intensity, session duration, total treatment duration and progression.
Choose a meaningful comparator.
Another active rehabilitation programme may provide more clinically useful information than no treatment.
Measure the treatment participants actually receive.
Prescribed exercise and completed exercise are not always the same.
Include activity and participation outcomes.
A statistically significant improvement in impairment does not necessarily mean that somebody walks more, uses their arm more or participates more in everyday life.
Consider long-term follow-up.
Many neurorehabilitation studies demonstrate short-term improvement but provide limited evidence about retention.
Consider patient heterogeneity.
Disease stage, impairment severity, cognition, fatigue, age and comorbidity may influence rehabilitation response.
Make sure the project is feasible.
A smaller but well-designed research question is usually more useful than an ambitious study that cannot recruit enough participants or deliver the intervention reliably.

Before You Finalise Your Research Topic

Research gaps change quickly as new trials and systematic reviews are published.

Before committing to a thesis or project, search the latest evidence to confirm that the question is still unanswered. Pay particular attention to recent systematic reviews, randomized controlled trials and the authors’ recommendations for future research.
