The popliteus muscle was studied during both normal gait and a series of planned exercises. Its activity during the walking cycle was shown to begin shortly before heel-strike and to continue throughout three-quarters of the stance phase. During the exercises the muscle was active during internal rotation of the tibia on the femur, and during normal gait the phasic activity of the popliteus coincided with internal rotation of the tibia on the femur. It was concluded that the basic function of the popliteus is to help to bring about and maintain internal rotation of the tibia on the femur.
在正常步态和一系列有计划的运动过程中对腘肌进行了研究。结果显示，其在步行周期中的活动在足跟触地前不久开始，并在整个站立期的四分之三阶段持续。在运动过程中，该肌肉在胫骨相对于股骨的内旋过程中处于活跃状态，而在正常步态中，腘肌的阶段性活动与胫骨相对于股骨的内旋同时发生。得出的结论是，腘肌的基本功能是帮助实现并维持胫骨相对于股骨的内旋。
