【摘要】：人体运动是一个复杂的过程，研究人体运动对于很多领域有着非常深远的意义。步态分析就是人体运动研究的一个重要的方面，可以多方面的评估人体运动功能的好坏。步态分析系统则是近年来随着人们对步态分析的关注和研究而出现的科技产品，可以对人体的步态情况提供全方位的分析并得出分析结果，为医生提供临床诊断依据，为患者更好的了解自己的病情提供参考。本文采用低成本、低功耗的传感器和MCU搭建的硬件节点电路，开发了无线数据采集节点和无线数据接收板，实现对运动数据的实时采集。配合相应的步态分析算法，对采集到的六轴运动数据在LabVIEW平台上进行相应的处理，得出步长、髋膝关节角度等重要步态参数，实现对步态的分析。最后通过实验室的系统测试，，验证了该系统的稳定性，可以满足临床实验的要求。最终选择了嘉兴二院康复中心进行临床实验，得出了该系统可以初步满足临床步态分析需要的结论。
[Abstract]:Human motion is a complicated process, and it is of great significance to study human motion in many fields. Gait analysis is an important aspect of human motion research. Gait analysis system is a scientific and technological product which appears with the attention and research of gait analysis in recent years. It can provide a comprehensive analysis of the gait situation of human body and obtain the analysis result, and provide the clinical diagnosis basis for the doctor. For patients to better understand their own disease to provide reference. In this paper, the hardware node circuit of low cost and low power consumption sensor and MCU is used to develop wireless data acquisition node and wireless data receiving board to realize real-time acquisition of moving data. With the corresponding gait analysis algorithm, the collected six-axis motion data are processed on the LabVIEW platform, and the important gait parameters such as step size, hip and knee joint angle are obtained, and the gait analysis is realized. Finally, the stability of the system is verified by the system test in laboratory, which can meet the requirement of clinical experiment. Finally, the rehabilitation center of Jiaxing second Hospital is selected for clinical experiment, and the conclusion is drawn that the system can meet the needs of clinical gait analysis.
