一种人体步态轨迹测量方法

A Kind of Measurement Method for Human Gait

为研究人体的步态运动规律,采用基于拉线传感器检测系统和人体关节角度测量装置,对人在不同路况下行走时踝关节运动轨迹和下肢关节角度进行了测量,根据人体下肢刚体模型和数据融合方法对测量结果进行了分析和处理,得到了人在上楼梯、平地行走和下楼梯时的步态轨迹和3种路况下的支撑相;上楼梯时的支撑相最大,平地行走次之,下楼梯最小。测量结果为了解人体运动规律和康复治疗提供了依据。

To study the regular human gaits, the test system based on string displacement sensor and human joint angle measurement instrument are used to measure the motion trajectory of anklebone and the joint angles of lower limb under walking in different road conditions, and the measurement data is analyzed and treated based on human rigid-body model and with data fusion method. Then the gait-trajectories and stand-phases are gotten under the condition of upstairs, normal walking and downstairs. The result shows that the longest stand- phase is in upstairs condition, the middle is normal walking and the shortest is downstairs. The result provides further understanding of the bio-mechanical principles for human movements and supplies foundation for rehabilitation treatment.
