A multichannel functional electrical stimulation (FES) system for the restoration of quadriplegic upper extremity function is described. The system is composed of a personal computer NEC PC-8801mkII, peripheral electronic circuits, CRT display and respiratory sensors for volitional control by the patient, and percutaneous electrodes. A C4 quadriplegic patient could drink canned tea by herself by using this FES system. Distinct features of the system are as follows: 1) Versatile volitional control was realized by controlling the memory allocation of the stored stimulation data by voluntary respiratory signals. 2) Sophisticated fine control of the fingers, wrists, and elbow was realized by creating the multichannel stimulation data from recorded myoelectric activities of normal subjects during movements of the upper limb.
描述了一种用于恢复四肢瘫痪患者上肢功能的多通道功能性电刺激（FES）系统。该系统由一台NEC PC - 8801mkII个人计算机、外围电子电路、阴极射线管显示器、用于患者自主控制的呼吸传感器以及经皮电极组成。一名C4四肢瘫痪患者通过使用该FES系统能够自己喝罐装茶。该系统的显著特点如下：1）通过自主呼吸信号控制存储刺激数据的内存分配，实现了通用的自主控制。2）通过根据正常受试者上肢运动期间记录的肌电活动创建多通道刺激数据，实现了对手指、手腕和肘部的精细控制。
