This paper describes the development of an implanted neuroprosthesis for restoring hand and arm function to individuals with high level tetraplegia resulting from C1-C4 spinal cord injury. These individuals have complete paralysis below the level of the neck and are thus highly disabled. The neuroprosthesis under development will restore basic upper extremity movements needed for simple yet important daily activities such as eating and grooming. Simulations performed with a musculoskeletal model of the shoulder and elbow indicate that existing stimulation technology using a realistic number of stimulation channels should be sufficient for providing these functions. The neuroprosthesis will utilize 24 channels of stimulation, muscle-based electrodes for stimulation of hand muscles, and nerve cuff electrodes for stimulation of shoulder and elbow muscles. The two implanted stimulators also include a total of four implanted bipolar EMG recording channels that sample activity in neck and facial muscles. These signals, along with measurements of head orientation, will provide the user command interface for this system.
本文描述了一种植入式神经假体的研发，该假体旨在恢复因C1 - C4脊髓损伤导致高位截瘫的患者的手部和手臂功能。这些患者颈部以下完全瘫痪，因此严重残疾。正在研发的神经假体将恢复简单但重要的日常活动（如进食和梳洗）所需的基本上肢运动。使用肩部和肘部的肌肉骨骼模型进行的模拟表明，采用实际数量的刺激通道的现有刺激技术应足以提供这些功能。该神经假体将利用24个刺激通道、用于刺激手部肌肉的基于肌肉的电极以及用于刺激肩部和肘部肌肉的神经袖套电极。两个植入式刺激器还总共包括四个植入式双极肌电图记录通道，用于采集颈部和面部肌肉的活动。这些信号，连同头部方向的测量结果，将为该系统提供用户命令界面。
