Abstract

Objective: The aim of the study was to compare electromyography (EMG) activities among gluteus medius (GMed), vastus medialis oblique (VMO), and vastus lateralis (VL) muscles during eccentric and concentric phases of forward step up (FSU), and wall single leg squat (WSS) in individuals with patellofemoral pain syndrome (PFPS).

Materials and methods: Ten females with PFPS were recorded EMG activities of GMed, VMO, and VL muscles during performed the FSU, and WSS exercises. Research procedures were approved by the MU-IRB (Mahidol University Institutional Review Board). EMG activities among muscles were compared by using one way ANOVA with Bonferroni post-hoc test in each of the eccentric and concentric contraction phases.

Results: Findings demonstrated significant greater muscle activities of the VMO and VL than GMed during concentric phase of the FSU and during both concentric and eccentric phases of the WSS.

Conclusion: The FSU and the WSS were able to use for stimulating thigh muscle activations in the VMO, VL, and GMed, respectively in individuals with patellofemoral pain syndrome.
