摘要:

脑卒中后偏瘫的康复干预对于恢复其运动功能十分重要。基于健侧肢体信号,应用于患侧肢体的功能性电刺激是改善偏瘫有潜力的干预手段。我们基于表面肌电图和支持向量机模型,研究了一种用于促进脑卒中偏瘫肢体功能恢复的自我管理、多运动、力调制功能性电刺激原型系统。文章讨论了该系统硬件设计和算法。我们认为该原型系统有望在临床用于促进脑卒中偏瘫肢体功能恢复的康复训练。

Abstract:

Hemiparesis is one of the most common consequences of stroke. Advanced rehabilitation techniques are essential for restoring motor function in hemiplegic patients. Functional electrical stimulation applied to the affected limb based on myoelectric signal from the unaffected limb is a promising therapy for hemiplegia. In this study, we developed a prototype system for evaluating this novel functional electrical stimulation-control strategy. Based on surface electromyography and a vector machine model, a self-administered, multi-movement, force-modulation functional electrical stimulation-prototype system for hemiplegia was implemented. This paper discusses the hardware design, the algorithm of the system, and key points of the self-oscillation-prone system. The experimental results demonstrate the feasibility of the prototype system for further clinical trials, which is being conducted to evaluate the efficacy of the proposed rehabilitation technique.
