人类的直立行走,其过程十分复杂。正如 Bernstein 指出的,就象在管弦乐队中,各个乐器演奏各自的乐谱那样,在步行动作中,各个关节再现各自的运动曲线,各个质量中心依次获得加速,各肌腱做出稳定的按一定规律变化的旋律。然而种种原因(事故或疾病)造成下肢截肢、畸形或偏瘫使得协调的步态遭到破坏,如何在康复治疗过程中对安装假肢或矫形后的步态进行评价仍然是人们关注的研究课题。 Human upright walking, the process is very complicated. As Bernstein points out, just as in the orchestra, each instrument plays its own individual score, each joint reproduces its own motion curve during walking and accelerates each mass center in turn, with each tendon making a constant, constant change Melody. However, due to various reasons (accidents or diseases), lower extremities amputation, deformity or hemiplegia make the coordinated gait was destroyed. How to evaluate the gait after prosthetic or orthopedic rehabilitation during rehabilitation is still a research topic of concern.
