Portable knee joint postoperative rehabilitation training monitoring and evaluating device and method

According to the portable knee joint postoperative rehabilitation training monitoring and evaluating device and method, a 3D model is constructed through multiple IMU devices for real-time dynamic tracking, the characteristics of IMU and sEMG are analyzed from the time-frequency domain, a quantitative analysis report is generated, and the rehabilitation condition of a patient is investigated from multiple angles. Besides, in consideration of the communication problem among a plurality of wireless devices, the invention provides a synchronous acquisition control method for an acquisition time sequence, so that the data acquired by the two legs have high synchronism in the acquisition time sequence. The device is easy to carry, convenient to use and not affected by the environment, and the problem that most wearable devices are inconvenient to carry is solved. 本发明提出一种便携式膝关节术后康复训练监测评估装置及方法，通过多个IMU设备构建3D模型实时动态跟踪，并从时频域分析IMU和sEMG的特征，生成量化分析报告，从多个角度考察患者的康复情况。此外，考虑到多个无线设备之间的通信问题，本发明提出了一种采集时序同步采集控制方法，使双腿采集到的数据在采集时序上具有高
