Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
1. The conversion to consent (%) is the percentage of those people who are eligible who agree to consent to the trial up to the end of recruitment <br>2. Eligibility rate (%) is measured as the percentage of people with PFP who are eligible for the study ( e.g.hip weakness) up to the end of recruitment<br>3. Adherence rate to treatment (%) is measured as the percentage of treatment session completed up to the end of the treatment period (6 weeks)<br>4. Adherence rate to appointments (%) is measured as the percentage of appointments attended up to the end of the treatment period (6 weeks)<br>5. Attrition rate (%) is measured as the percentage of participants who remain in the study until the end of follow up at 8 weeks.<br>6. Missing data (%) is measured as percentage of data missed in the outcome measure at 8 weeks follow up<br>7. Treatment efficacy is measured using a numerical rating scale, the Anterior Knee Pain Scale (AKPS) and the global rating of change scale (GROC) at 8 weeks follow up

Secondary Outcome Measures

Name	Time	Method
1. Peak hip internal rotation angle (peak IR) of the thigh with respect to the pelvis is measured using VICON motion capture stystme at baseline and 8 weeks follow up<br>2. Peak hip adduction angle (peak ADD) of the thigh with respect to the pelvis is measured using VICON motion capture system at baseline and 8 weeks follow up<br>3. Total coronal hip range of movement (coronal ROM) is measured using VICON motion capture system at baseline and 8 weeks follow up<br>4. Total transverse hip (ROM) (transverse ROM) is measured using VICON motion capture system at baseline and 8 weeks follow up<br>5. Peak isokinetic hip abduction strength is measured using Biodex isokinetic dynamometer at baseline and 8 weeks follow up<br>6. Peak isokinetic knee extension strength is measured using Biodex isokinetic dynamometer at baseline and 8 weeks follow up
