The purpose of this study was to investigate if, in three weeks, the vastus medialis muscle could be trained to contract independently of the vastus lateralis muscle. Ten subjects attended electromyographic biofeedback training sessions five days a week for three weeks for one half hour each day. During the first two weeks the subjects concentrated on decreasing the activity level of the vastus lateralis muscle, and during the final week they tried to increase the vastus medialis muscle activity level. Significant differences were found in the change in muscle activity level of the vastus lateralis muscle over the first two weeks, in the change of muscle activity level of the vastus medialis muscle over the third week, and in the difference between vastus medialis and vastus lateralis muscle activity levels from the first to the third weeks.
本研究的目的是调查在三周内，股内侧肌是否能够被训练得独立于股外侧肌进行收缩。10名受试者每周参加5天的肌电图生物反馈训练课程，为期三周，每天半小时。在前两周，受试者专注于降低股外侧肌的活动水平，而在最后一周，他们试图提高股内侧肌的活动水平。在前两周股外侧肌的肌肉活动水平变化、第三周股内侧肌的肌肉活动水平变化以及从第一周到第三周股内侧肌和股外侧肌的肌肉活动水平差异方面，均发现了显著差异。
