Effects of Attentional Focus Strategies During Isokinetic Quadriceps Training on Strength and Functional Performance in Individuals With Patellofemoral Pain Syndrome.
Turkey (Türkiye)36 participantsStarted 2026-02-02
Plain-language summary
Patellofemoral pain syndrome (PFPS) is a multifactorial musculoskeletal condition that is common particularly among young and physically active individuals, negatively affecting activities of daily living and physical performance. Although exercise therapy is considered the gold standard in the management of PFPS, there is limited evidence regarding the effectiveness of motor learning strategies applied during exercise. This study aims to shed light on how motor learning approaches can be optimized in clinical rehabilitation by comparing the effects of internal and external focus strategies used during exercise on muscle activation, functional performance, and pain.
This research will make a methodological contribution to the literature through the objective evaluation of muscle mechanical properties using isokinetic assessment and the MyotonPRO device. The findings are expected to clarify the effects of attentional focus strategies on therapeutic outcomes in PFPS rehabilitation and have the potential to provide an evidence-based guide for physiotherapy practice. In this way, the study may contribute to the development of new approaches aimed at improving both clinical effectiveness and patient adherence.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Aged between 18 and 45 years.
* Diagnosed with patellofemoral pain syndrome (PFPS).
* Anterior or retropatellar knee pain persisting for at least four weeks with a VAS score \> 3.
* Pain exacerbated by at least two functional activities (e.g., squatting, stair climbing, prolonged sitting).
* Willing to regularly participate in the 6-week program throughout the study period.
Exclusion Criteria:
* History of patellar subluxation or dislocation.
* Anterior or posterior cruciate ligament insufficiency.
* Lower extremity fractures.
* Neurological or systemic musculoskeletal disorders.
* Rheumatoid arthritis or other inflammatory joint diseases.
* History of knee surgery, meniscal injury, or any other underlying musculoskeletal condition that would prevent the participant from performing the exercises.

* Participation in a similar exercise program within the last 3 months.
* Radiographic evidence of osteoarthritis classified as Kellgren-Lawrence grade 2 or higher.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
