当下肢肌肉力量退化时，人类（尤其是老年人）依靠上肢的帮助站立是很常见的。在这种情况下，由于大腿、躯干和上肢由膝关节以上的一个闭合连接组成，髋关节力矩不能仅从关节的位置信息作为一个逆问题来确定。因此，本研究试图通过测量手对下肢的作用力以及地板反作用力来分析下肢力矩的逆动力学。
Introduction When the muscular strength of the lower limbs deteriorates, it is common for humans (particularly the elderly) to stand up with assistance from their upper limbs. In such cases, because the thighs, the trunk and the upper limbs consist of a closed link from the knee joint upwards, the hip joint moment cannot be determined as an inverse problem from positional information concerning the joints alone. Accordingly, this study attempts to analyze the inverse dynamics of the lower limb moments by measuring the force acting of the lower limbs from the hands as well as the floor reaction force.
