The aim of tis report is to describe the effects of a dual-channel functional electrical stimulation (FES) system applied daily as an orthotic device to the dorsiflexors and hamstrings muscles in a subject with chronic hemiparesis. Prior to the application of FES, the patient's gait was characterized by a footdrop and knee hyperextension during stance. measurements of gait performance were collected before FES application, after a conditioning period of six weeks, and following ten months of daily use. Outcomes included lower limb kinematics and temporal gait measures. The kinematic assessments indicated significant benefits for gait with the dorsiflexors and hamstrings FES, as compared to no stimulation and peroneal FES alone. In addition ot improved ankle control, knee hyperextension was reduced during stance, and the self-selected comfortable gait velocity increased following ten months of daily use. The results of this report suggest that dual-channel FES for the dorsiflexors and hamstrings muscles may affect ankle and knee control beyond that witch can be attributed to peroneal stimulation alone. The positive effects observed in this case study point to the potential of dual-channel FES as a viable treatment options in the rehabilitation of patients with similar impairments.
本报告旨在描述一种双通道功能性电刺激（FES）系统的效果，该系统作为一种矫形装置，每天应用于一名慢性偏瘫患者的背屈肌和腘绳肌。在应用FES之前，患者的步态特征为站立期足下垂和膝关节过度伸展。在应用FES之前、经过六周的适应期后以及经过十个月的每日使用后，收集了步态性能测量数据。结果包括下肢运动学和步态时间测量。运动学评估表明，与无刺激和仅腓骨肌FES相比，背屈肌和腘绳肌FES对步态有显著益处。除了改善踝关节控制外，站立期膝关节过度伸展减少，经过十个月的每日使用后，自我选择的舒适步态速度增加。本报告的结果表明，用于背屈肌和腘绳肌的双通道FES可能对踝关节和膝关节控制产生的影响超出了仅由腓骨肌刺激所能产生的影响。在本案例研究中观察到的积极效果表明，双通道FES在康复治疗中对具有类似损伤的患者具有作为一种可行治疗选择的潜力。
