The four-bar linkage mechanism used by many designers for the knee joint of an above-knee prosthesis can provide knee rotation suitable for walking only. In Afro-Asian countries people are habituated to the squatting posture in their daily activities. A six-bar linkage knee-ankle mechanism above-knee prosthesis with a pneumatic swing phase control is developed and its analysis shows its suitability for producing a motion closely resembling that of a normal subject during walking and squatting.
许多设计师用于大腿假肢膝关节的四杆连杆机构仅能提供适合行走的膝关节旋转。在亚非国家，人们在日常活动中习惯蹲姿。一种带有气动摆动阶段控制的六杆连杆膝-踝机构大腿假肢被研发出来，其分析表明它适合在行走和蹲姿时产生与正常受试者极为相似的运动。
