Design of upper extremity motor function mirror rehabilitation system for post-stroke patients based on FES

摘要

An upper extremity motor function mirror rehabilitation method based on Functional Electrical Stimulation (FES) was proposed to provide subject-oriented rehabilitation training for hemiplegic patients with upper limb motor dysfunction. Firstly, recognize the motion pattern of the healthy side by Microsoft Kinect. The motion pattern consists of three kind of mode, i.e. slow speed mode, medium speed mode, fast speed mode. Secondly, the paralyzed upper joints were controlled to track the pattern of the healthy side by stimulating appropriate muscles. The stimulating intensity, i.e. the width of the current pulse, is controlled with iterative learning control method. Experiments on healthy subject indicated that this rehabilitation system could help post-stroke patients conduct customized subject-oriented training effectively.
