Summary: | •EMG activity of the vastus lateralis, biceps femoris, gluteus maximus and medius.•EMG and kinematic analysis in patients with patellofemoral pain syndrome.•EMG analysis of the hip and knee muscles on eccentric and concentric phases.
This study aimed to compare the concentric and eccentric activity and the temporal order of peak activity of the hip and knee muscles between women with patellofemoral pain (PFP) and healthy women during the single leg triple hop test (SLTHT). Electromyographic (EMG) and Kinematic data were collected from 14 healthy women (CG) and 14 women diagnosed with PFP (PFG) during a single session of the single leg triple hop test. Integral surface electromyography (iEMG) data of the hip and knee muscles in eccentric and concentric phases and the length of time that each muscle needed to reach the maximal peak of muscle activity were calculated. The iEMG in the eccentric phase was significantly higher (p |
