An observational study in Patellofemoral Pain (PFPS), sponsored by Ahram Canadian University. Not yet recruiting at 1 site in Egypt. Open to male participants aged 18 Years to 35 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-12-26.
Sponsored by Ahram Canadian University · Observational
The study aims to explore the effect of body position (side-lying versus standing) on hip abductors muscle strength and activation in individuals with and without PFPS and then to compare these measures between the two groups in each position
A cross-sectional comparative study involving 44 subjects (22 subjects with PFPS and 22 healthy controls), aged 18-35 years. The study will measure hip abductor muscle strength (Peak torque, Maximal total work) using the Biodex Isokinetic System 4 PRO and muscle activity (%MVC) of the gluteus medius, gluteus maximus, and tensor fascia lata using Surface EMG (Noraxon Ultium EMG). Measurements will be taken in both standing and side-lying positions.
297 studies on the registry are indexed under Patellofemoral Pain Syndrome; 74 are open to participants now.
This study's planned enrollment of 44 is close to the median of 43 across 48 observational studies indexed under Patellofemoral Pain Syndrome.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
