本研究的目的是调查健康的非跌倒老年人行走的运动学和动力学特征，以制定跌倒的预测参数。在具有两个集成力平台和用于三维运动分析的光电系统的步行回路上完成了为期一年的前瞻性试验。对 54 名志愿者进行了步态调查，这些志愿者都是 60 岁以上、上一年没有跌倒过的健康人。在一年的时间里，每两个月与受试者进行一次联系。结果显示，接受检测的54人中有16人摔倒。跌倒者组和非跌倒者组之间没有显着的年龄差异。跌倒者走得更慢，并且倾向于使用双支撑更长的时间。坠落者的力量较小，但主要表现出较小的力量和力矩变化。脚踝和臀部的活动范围减少。我们注意到步行模式的变化，显示摆动阶段脚踝背屈的延迟。总之，亚临床步态参数发生在老年人中。行走时神经运动模式改变的出现与跌倒的倾向有关。尤其是踝关节背屈延迟似乎预示着跌倒。
The aim of this study was to investigate the kinematic and kinetic characteristics of walking in healthy non-faller elderly in order to develop predictive parameters for falls. A 1-year prospective trial was completed on a walking circuit with two integrated force platforms and an optoelectronic system for three-dimensional movement analysis. Gait was investigated in 54 volunteers who were healthy people over 60 who had not fallen in the previous year. The subjects were contacted 2-monthly over a period of 1 year. The results showed that 16 of the 54 people tested had fallen. There was no significant age difference between the group of fallers and the group of non-fallers. Fallers walked more slowly and tended to use a double support for a longer period of time. Fallers were less powerful but mainly showed fewer power and moment variations. The range of motion at the ankle and the hip was reduced. We noticed a change in the walking pattern, showing a delay in the dorsiflexion of the ankle at the swing phase. In conclusion, subclinical gait parameters occur in older people. The advent of neuromotor pattern alterations when walking is related to the tendency to fall. Ankle dorsiflexion delays, in particular, appear to be predictive of falls.
