摘要

Objective:Patellofemoral pain syndrome is a patellar tracking dysfunction usually associated with vastus medialis oblique (VMO) weakness, and subsequently, a small VMO: vastus lateralis (VL) ratio. Several early electromyographic (EMG) studies have defined specific limb positions (such as external rotation of the hip) that preferentially activate the VMO. However, whether preferential activation of the VMO successfully translates into increased VMO:VL ratios with training has not been investigated. The purpose of our study was to investigate the effects of hip rotation on the mean VMO:VL EMG ratio using EMG biofeedback training over a 5-day period.
