摘要： 目的 基于 Matlab建立一套可用于脊髓损伤非人灵长类恒河猴的三维步态数据处理的软件包，实现原始数据读入、步态周期自动划分、多种步态参数计算和绘图等功能。方法 使用Vicon系统对健康及脊髓损伤后6周的恒河猴后肢三维步态数据进行采集，获取双后肢连续步进的运动学数据。基于 Matlab开发三维步态数据处理软件，进行步态周期划分及 140种步态参数计算。结果 该软件包成功读取恒河猴的原始三维步态数据，完成对正常与异常(脊髓损伤后)后肢步态周期的自动划分，报告并生成相应的曲线图。结论 本研究建立的软件包扩展了Vicon数据的通用性，实现步态周期的自动划分及良好的人机交互，计算多种步态参数并实现结果的可视化。

Abstract: Objective To establish a three- dimensional hindlimb gait data toolkit (THGT) for healthy and spinal cord injured (SCI) non-human primate (rhesus monkey) based on Matlab to realize upload of original data, automatic gait division, calculation and drawing of multiple gait parameters, etc. Methods Vicon system was used to collect three-dimensional hindlimb gait data of healthy and SCI (after 6 weeks) rhesus monkey to obtain the kinematics data of both hindlimbs in continuous strides. It was analyzed with THGT to process the gait division, calculation and drawing of multiple gait parameters. Results THGT read the data, distinguished cycles of gait, calculated 140 kinds of gait parameters and drew graphs of the results. Conclusion THGT extends the universality of the Vicon data, realizes automatically gait division and friendly interactive interface, and puts out the visible results.
