本研究旨在探讨无线惯性传感器系统应用于步态康复临床评估的可行性。一个偏瘫患者的步态运动与传感器系统进行了测量，在10米步行之前和之后的机器人辅助步态训练在一天。根据测量的角速度和加速度信号，基于卡尔曼滤波器计算出节段倾角和下肢关节角。步态事件的时间也检测脚的角速度和小腿加速度信号。测量数据显示训练后步态运动发生了变化，这被认为是治疗师指导下的改善。机器人系统可以有效地进行基于指令的训练。无线惯性传感器系统将有助于临床康复运动的测量和评估。
This study aimed to test a possibility of using wireless inertial sensor system in evaluation of gait rehabilitation clinically. Gait movements of a hemiplegic subject were measured with the sensor system during 10 m walking before and after robotic-assisted gait training in a day. Segment inclination angles and joint angles of the lower limbs were calculated from measured angular velocities and acceleration signals based on Kalman filter. Gait event timings were also detected by foot angular velocities and shank acceleration signals. The measured data showed that gait movement changed after the training, which were considered to be improvements by the instruction of the therapist. The robotic-system could be effective for the training based on the instruction. The wireless inertial sensor system would be useful for measurement and evaluation of movements in rehabilitation clinically.
