利用两个大的测力板,研究了人体步态起始、停止和转弯三个阶段的地板反力特性,得到了人体步态起始和停止时地板反力作用点和人体质心的时间历程。在步态起始阶段,不仅在施力点上,而且在地板反力上也出现了反向波动现象。实验表明,当一个人开始走路时,会发生反向波动。结果表明:步态停止与步态起始的时间反转运动大致相似;步态转向是步态停止和步态起始的连续运动。
The characteristics of floor reaction forces are investigated using two large force plates in the three phases of human gait, that is, initiation, stopping and turning, The time histories of the point of application and the center of the body mass in gait initiation and stopping are obtained. In gait initiation, the phenomena of inverse fluctuation are noticed not only in the point of application, but in the floor reaction forces as well. It becomes clear experimentally that inverse fluctuations occur when a person initiates walking. The following results are also described: gait stopping is roughly similar to the time-reverse motion of the gait initiation; gait turning is the continuous motion of gait stopping and gait initiation.
