摘要

面向我国脑卒中和老龄化等原因导致的下肢运动功能障碍患者

开发了一种基于人体足底压力分布和重心轨迹的双腋支撑下肢康复减重系统。首先

分析研究了减重支撑训练对足底压力的影响;其次

基于人机工程学理论并结合人体重心轨迹研究

对总体结构进行了分析与设计

并确定了相关尺寸;然后

通过静力学分析

验证了结构的可靠性;最后

对减重模块进行了运动学分析和动力学仿真。该系统可帮助下肢运动功能障碍的患者实现模仿正常人行走的康复训练。

Abstract

For the patients with lower extremity motor dysfunction caused by stroke and aging

a new weight loss system for double axillary support lower limb rehabilitation based on barycentre trajectory of human body was developed.Firstly

the influence of weight loss support training on plantar pressure was analyzed and studied.Secondly

based on ergonomics theory and the study of barycentre trajectory of human body

the overall structure was analyzed and designed

and the relevant size was determined.Thirdly

the reliability of the structure was verified by statics analysis.Finally

the kinematics analysis and dynamic simulation of the weight reduction module were carried out.The system can help the patients with lower extremity motor dysfunction realize the rehabilitation training of imitating the normal walking.
