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

NCT07305610 | Not Yet Recruiting

• 1 other identifier: Cairo University
• Study Type: observational
• Target: 44
• Locations: 1 country
• Sites: 1

Brief Summary

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

Conditions

Patellofemoral Pain (PFPS)

Keywords

Hip Abductors; Muscle Strength; Muscle Activity; Side-lying; Standing

Outcome Measures

Primary Outcomes (2)

• Muscle activity (%MVC) of the gluteus medius, gluteus maximus, and tensor fascia lata

  using SEMG

  During the assessment procedure (single time point)

• Peak torque (Nm) of hip abductors muscles

  using isokinetic

  During the assessment procedure (single time point)

Secondary Outcomes (2)

• Maximal total work (J) during concentric and eccentric contractions

  During the assessment procedure (single time point)

• The Arabic Version of the Kujala Score (Anterior Knee Pain Scale)

  Baseline/Pre-assessment

Study Arms (2)

PFPS Group

Subjects with unilateral PFPS diagnosed by an orthopedist; age 18-35 years; normal BMI

Control Group
