Quantification of abnormal gait by one direction frontal video

本研究的目的是检验单方向正面视频的步态分析方法。考虑到该方法的准确性，我们利用单向正面视频的步态分析来评估OA患者的下肢直线和异常步态。结果表明，基于单方向正面视频的步态分析可以对人体步态进行评价。结果表明，OA膝关节站立时垂直摆动减少，膝关节对膝关节的直线变化。结果表明，该方法可用于评价患者的行走异常。

The purpose of this study is to examine the gait analysis method by one direction frontal video. We evaluated lower limb alignment and the abnormal gait of OA patients by gait analysis using one direction frontal video, with considering the accuracy of this method. The result suggested that the gait analysis by the one direction frontal video could evaluate the human gait. Results were shown that decrease of vertical sway at OA knee stance and the change of the knee joint alignment with OA knee thrut. The result suggested that this method could evaluate theabnormality of patient walking.
