In the treatment of muscle imbalances around the knee, hip adduction and the contraction of adductor magnus have been used to facilitate vastus medialis obliquus (VMO) to a greater extent than vastus lateralis (VL). This study was conducted to investigate the effectiveness of this technique. Hip adduction was superimposed onto the contraction of quadriceps femoris in a weight bearing (WB) and a non-weight bearing (NWB) position at three levels of hip adduction force. The muscle activity of VMO and VL was recorded using electromyography with the ratio of the recordings of VMO to VL used for comparison. The activity of VMO compared with VL was greater in WB than NWB without hip adduction. VMO activity increased relatively more than VL with the addition of each level of hip adduction in WB and only with maximal hip adduction in NWB. The results provide support for the use of this technique.
在治疗膝关节周围的肌肉失衡时，与股外侧肌（VL）相比，髋内收及大收肌收缩被用于更大程度地促进股内侧斜肌（VMO）。本研究旨在调查该技术的有效性。在三个髋内收力水平下，将髋内收叠加到负重（WB）和非负重（NWB）位的股四头肌收缩上。使用肌电图记录VMO和VL的肌肉活动，并将VMO与VL的记录比值用于比较。在无髋内收时，负重位时VMO与VL相比的活动大于非负重位。在负重位时，随着每个髋内收水平的增加，VMO活动相对VL增加得更多，而在非负重位时仅在最大髋内收时VMO活动增加相对更多。这些结果为该技术的应用提供了支持。
