Overview
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
Detailed description
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.
Primary outcome measures
- Muscle activity (%MVC) of the gluteus medius, gluteus maximus, and tensor fascia lata [Time frame: During the assessment procedure (single time point)]
- Peak torque (Nm) of hip abductors muscles [Time frame: During the assessment procedure (single time point)]
Secondary outcome measures (2)
- Maximal total work (J) during concentric and eccentric contractions [Time frame: During the assessment procedure (single time point)]
- The Arabic Version of the Kujala Score (Anterior Knee Pain Scale) [Time frame: Baseline/Pre-assessment]
Eligibility criteria
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
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
