Mind over muscle: new study tests if focus cues boost knee rehab
NCT ID NCT07384858
First seen Jun 27, 2026 · Last updated Aug 19, 2026 · Updated 2 times
Summary
This study looks at whether telling people to focus on their muscles (internal focus) or on an external object (external focus) during knee exercises leads to better strength and less pain. Researchers will enroll 36 adults with patellofemoral pain syndrome and track their progress over 6 weeks. The goal is to find the best way to give exercise instructions for faster recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- attentional focus strategies (internal vs. external cues during exercise)
- What this could lead to
- If successful, this could show that simple changes in how you think during exercise can improve knee strength and reduce pain, leading to better rehab programs.
- What could go wrong
- This is a small, early-stage study with only 36 participants, so results may not apply to everyone. The intervention is just a different way of giving exercise instructions, so any benefit is likely modest.

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. * Pregnancy or postpartum period. * Participation in a similar exercise program within the last 3 months. * Radiographic evidence of osteoarthritis classified as Kellgren-Lawrence grade 2 or higher.
