Purpose: The effects of Hip muscle fatigue on lower extremity joint coupling in females with and without Patellofemoral pain syndrome study. Design: Not blinded, control without placebo, parallel. Inclusion criteria for experimental group: complain of 1-anterior knee pain during squatting, prolonged sitting, stair descent, running 2-pain during compression of the patella into the femoral condyles. Inclusion criteria for control group: no history of hip, knee, ankle pathology or surgery. Exclusion criteria for both groups: history of hip, knee, ankle pathology or surgery. Intervention: Fatigue of Hip abductor muscles & fatigue of hip extensor muscle. Time of intervention: Less than 15 minutes. Primary outcome measure: joint coupling angle between knee and ankle joints during walking.

Intervention groups
1
Description
The protocol of muscle fatigue is the same for both groups. Fatigue protocol for hip-abductor muscles: position of participants is supine with the knee in extension. Participants perform isometric hip abduction contraction with resistance. A digital myometer measures maximal voluntary isometric contraction (MVIC) before and after fatigue protocol. The fatigue protocol continues until participants MVIC drops below 70% of the pre-fatigue value. Fatigue protocol for hip- extensor muscles: position of participants is side lying with the knee in flexion. Participants perform isometric hip extension contraction with resistance. A digital myometer measures maximal voluntary isometric contraction (MVIC) before and after fatigue protocol. The fatigue protocol continues until participants MVIC drops below 70% of the pre-fatigue value.
