本研究旨在确定功能活动过程中臀中肌前段、中段和后段肌电活动的开始、持续时间和程度。将细线电极插入每个肌肉节段。应用三轴髋关节测角仪后，10名受试者均进行行走、爬行、上下楼梯、系鞋带、坐立、单肢站立等向前学习活动。根据开关活动评估的原始肌电图记录提供的结果表明，对于某些活动，三个节段的活动的开始、持续时间和程度是相似的。结果还证实，选定的功能活动会发生异步活动，从而证明臀中肌的三段概念模型是正确的。
This study was undertaken to determine the onset, duration, and degree of electromyographic activity in the anterior, middle, and posterior segments of the gluteus medius muscle during functional activities. Fine wire electrodes were inserted into each muscle segment. After a triaxial hip electrogoniometer was applied, each of the 10 subjects performed the activities of walking, crawling, stair ascending and descending, shoetying, sitting, and single limb-standing with forward learning. Raw electromyographic records evaluated on the basis of on-off activity provided results showing that the onset, duration, and degree of activity of the three segments was similar for some activities. Results also established that asynchronous activity occurred for selected functional activities, thereby justifying a three-segment conceptual model of the gluteus medius muscle.
