INFLUENCE OF SELECTED POSITIONS ON HIP ABDUCTORS STRENGTH AND ACTIVATION IN PATELLOFEMORAL PAIN SYNDROME IN MALES

INFLUENCE OF SELECTED POSITIONS ON HIP ABDUCTORS STRENGTH AND ACTIVATION IN PATELLOFEMORAL PAIN SYNDROME IN MALES

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.

Inclusion Criteria:

• Age 18-35 years; Normal BMI; Subjects in the PFPS group diagnosed with unilateral PFPS by an orthopedist; Healthy individuals without knee pain (for the control group)

Exclusion Criteria:

• History of lower limb surgery; Any neurological disorders; Musculoskeletal disorders affecting the lower limb; Additional sources of anterior knee pain (tendonitis, Osgood-Schlatter, bursitis, etc.); Any inflammatory diseases
