Abstract

Functional electrical stimulation (FES) of paralyzed muscles can facilitate walking after spinal cord injury (SCI). To test the orthotic effects of different FES walking protocols on lower joint kinematics in individuals with incomplete SCI. Three adults with motor incomplete SCI participated in this study. Their lower extremity motor scores [LEMS (left, right)] were as follows: subject A: 25/25, subject B:15/25, subject C:9/23. They were asked to randomly complete four conditions of overground walking in a 4-meter walkway (6-10 times/condition) including no FES, and three bilateral FES walking protocols as follows: drop-foot (tibialis anterior stimulation), flexor withdrawal (common peroneal nerve stimulation), and multi-muscle stimulation (stimulation of quadriceps and gastrocnemius in the stance phase, and hamstring and tibialis anterior in the swing phase). The FES system obtained gait phase information from the two footswitches located under the individuals’ feet. Three-dimensional kinematic analysis was undertaken to measure minimum toe clearance (MTC), ankle, and hip range of motion (ROM) using a 100 Hz eight infrared camera (Vicon Motion Systems, Oxford, UK). The three FES-walking conditions significantly increased MTC compared to the no-FES condition in all participants. A significant decrease in ankle ROM was seen in the drop-foot (all subjects), multi-muscle (subjects A and C), and flexor withdrawal (subject A) stimulations. Hip ROM increased in the drop-foot (subjects B and C), flexor withdrawal (subject B), and multi-muscle (subject C) stimulations. Three FES-walking protocols induced positive kinematic changes (increased hip flexion and toe clearance) during walking in subjects with incomplete SCI.

对瘫痪肌肉进行功能性电刺激(FES)可促进脊髓损伤(SCI)后的行走。 目的是测试不同的功能性电刺激行走方案对不完全脊髓损伤患者下关节运动学的矫形效果。 三名运动功能不全的成人脊髓损伤患者参与了这项研究。他们的下肢运动评分[LEMS(左、右)]如下:受试者A:25/25,受试者B:15/25,受试者C:9/23。他们被要求在 4 米长的人行道上随机完成四种条件下的地面行走(6-10 次/条件),包括不使用 FES,以及以下三种双侧 FES 步行方案:垂足(刺激胫骨前肌)、屈肌后撤(刺激腓总神经)和多肌刺激(在站立阶段刺激股四头肌和腓肠肌,在摆动阶段刺激腘绳肌和胫骨前肌)。FES 系统通过位于患者脚下的两个脚踏开关获取步态相位信息。通过三维运动学分析,使用 100 Hz 八红外摄像机(英国牛津 Vicon 运动系统公司)测量最小脚趾间隙(MTC)、踝关节和髋关节的运动范围(ROM)。 与无 FES 条件相比,所有参与者在三种 FES 步行条件下的 MTC 均明显增加。在落足(所有受试者)、多肌肉(受试者 A 和 C)和屈肌退缩(受试者 A)刺激下,踝关节活动度明显下降。在落足(受试者 B 和 C)、屈肌后撤(受试者 B)和多肌(受试者 C)刺激下,髋关节活动度有所增加。 在不完全性脊髓损伤受试者的行走过程中,三种FES行走方案都能诱发积极的运动学变化(髋关节屈曲和脚趾间隙增加)。
