辅以功能电刺激的实时步态训练与反馈分析系统

摘要

To solve the problem that mostly gait analysis is independent from the treatment, this work proposes a system that integrates the functions of gait training and assessment for foot drop treatment. The system uses a set of sensors to col ect gait parameters and designes multi-mode functional electrical stimulators as actuator. Body area network technology is introduced to coordinate the data communication and execution of the sensors and stimulators, synchronize the gait analysis and foot drop treatment. Bluetooth 4.0 is applied to low the power consumption of the system. The system realizes the synchronization of treatment and gait analysis. It is able to acquire and analyze the dynamic parameters of ankle, knee and hip in real-time, and treat patients by guiding functional electrical stimulation delivery to the specific body locations of patients.%该文研究设计了同步实现足下垂患者步态训练和康复评估的综合系统，以解决目前存在的足下垂治疗与步态分析分离的不足。系统采用多传感器采集各运动部位的参数，并设计了多重模式的功能性电刺激装置，引入了体域网技术协调传感器和刺激器的数据通讯及控制，同步实现步态实时分析与足下垂治疗。体域网应用了蓝牙4.0技术以降低系统功耗。系统实现了治疗与评估的同步，能够实时采集并分析训练时踝、膝、髋等部位运动参数，并同时对患病部位进行功能性电刺激治疗。
