摘要

近年来,动力式膝关节矫形器(power Knee Orthosis, PKO)已成为治疗步态、神经性步态、中风步态等康复活动中必不可少的辅助设备。现有的PKO主要用于进行康复活动,大部分都是充分利用PKO来驱动膝关节运动。这可能导致自主健全体进行膝关节运动活动的障碍,并导致肌肉退化。本文介绍了在功能性电刺激(FES)的辅助下,膝关节摆动活动的PKO的发展。PKO设计具有高后驱能力,允许fes在膝关节伸展期间辅助运动。实验采用两名健康受试者在三种不同条件下进行摆膝运动;膝关节摆动伴PKO,伴FES,伴FES和PKO。测量并记录膝关节角度运动。结果表明,fes辅助下的膝关节摆动治疗PKO是成功的。因此,发达的PKO能够促进fes辅助的膝关节摆动活动。

Development of Powered Knee Orthosis for FES-Assisted Knee Swing
Recently, Powered Knee Orthosis (PKO) becomes an essential assisting device in serving rehabilitation activities such as gait, neuropathic gait and stroke gait. Existing PKOs are mainly designed to perform rehabilitation activities and most of them fully utilized PKO to drive knee movement. This may contributed to discouragement of the voluntary able-body to perform knee movement activities and led to muscle degradation. This paper presents the development of PKO for knee swing activities aided by functional electrical stimulation, FES. The PKO is designed with high back-drive ability to allows FES-assisted movement during knee extension. The experiments were implemented on two healthy subjects performing knee swing for three different conditions; Knee swing with PKO, with FES and with both FES and PKO. The knee angle movement were measured and recorded. The results demonstrate the successful of the proposed FES-assisted knee swing with PKO. Thus the developed PKO is able to contribute to the FES-assisted knee swing activities.
