目的：本报告描述了仿生手套的操作，这是一种新型功能性电刺激 (FES) 设备，旨在改善脊髓损伤 (SCI) 或中风后瘫痪手的功能。设计：来自检测自愿手腕运动的手套中的传感器的信号用于控制肌肉的 FES，以产生手抓握或张开手。戴上手套后，其内表面的导电区域会自动与皮肤上的自粘式电极接触。环境和患者：本报告涉及 9 名 SCI 患者，他们在日常生活中使用该设备长达一年或更长时间。作为多中心临床试验的一部分，在埃德蒙顿、迈阿密和芝加哥的诊所进行了测量。结果测量和结果：九名受试者的肌腱固定术抓握的平均峰值力从 2.6N（被动）增加到 11.3N（手套主动）。即使肌肉在重复的抓握-释放循环后疲劳，主动力也明显大于被动抓握力。根据一分钟内完成的任务数量或受试者对任务难度的定性评分来判断，大多数体力任务在使用手套后都有显着改善。结论：仿生手套可以显着改善 C6-C7 SCI 患者的手部功能。 (C) 1997 年由美国康复医学大会和美国物理医学与康复学会颁发。
Objective: This report describes the operation of the Bionic Glove, a new functional electrical stimulation (FES) device designed to improve the function of the paralyzed hand after spinal cord injury (SCI) or stroke.Design: Signals from a sensor in the glove detecting voluntary wrist movement are used to control FES of muscles either to produce hand-grasp or to open the hand. When the glove is donned, conductive areas on its inside surface automatically make contact with self-adhesive electrodes on the skin.Setting and Patients: This report concerns nine people with SCI who have used the device in their daily lives for up to a year or more. Measurements were made at clinics in Edmonton, Miami, and Chicago as part of a multicenter clinical trial.Outcome Measures and Results: The mean peak force of tenodesis grasp in the nine subjects increased from 2.6N (passive) to 11.3N (glove active). Active force was significantly greater than passive grasp force even when muscles were fatigued after repetitive grasp-release cycles. Most manual tasks improved significantly with the use of the glove, as judged by the number of tasks completed in a minute or the subjects' qualitative ratings of task difficulty.Conclusion: The Bionic Glove can provide significant improvement of hand function in people with C6-C7 SCI.
