【摘要】：目的通过研究压电式步态分析系统在足底压力监测中的实际应用,为人体步态分析及其在临床医学及康复治疗作用提供参考。方法设计压电式步态分析系统,采集鞋垫中6个采集点的压力信号,通过蓝牙模块传输足底压力信号,并采用所设计手机APP和MATLAB软件分析和处理压力信号。结果利用MATLAB软件插值、颜色映射等功能绘制足底压力云图、压力中心蝴蝶图,通过测量双脚摆动相计算步行周期,手机APP实时监测足底压力以实现意外摔倒报警。结论该系统可实现站立姿态、平衡状态、步行周期及意外摔倒的监测,所得实验结果与临床研究结论基本保持一致,同时可穿戴式结构更适合于真实步行场景。
[Abstract]:Objective to study the practical application of piezoelectric gait analysis system in the monitoring of plantar pressure, and to provide reference for human gait analysis and its effect in clinical medicine and rehabilitation therapy. Methods the piezoelectric gait analysis system was designed to collect the pressure signals from 6 acquisition points in the insole and transmit the plantar pressure signals through Bluetooth module. The designed mobile phone APP and MATLAB software were used to analyze and process the pressure signals. Results MATLAB software interpolation, color mapping and other functions were used to draw plantar pressure cloud map, pressure center butterfly map, foot swing phase to calculate the walking cycle, mobile phone APP real-time monitoring plantar pressure to achieve accidental fall alarm. Conclusion the system can monitor the standing posture, balance state, walking period and accidental fall. The experimental results are consistent with the clinical findings, and the wearable structure is more suitable for real walking scenes.
