STIMULATION FOR CONTROL OF THE PARALYZED HAND IN THE C5/C6 SPINAL CORD INJURY

本研究旨在评价植入式刺激器系统的性能，该系统旨在为高位脊髓损伤四肢瘫痪患者的瘫痪上肢提供激活和控制。 第一代八通道植入式接收器刺激器已植入100多人，并已获得FDA的上市前批准。 我们已经开始评估一种更先进的第二代十通道植入式刺激遥测仪（IST）和植入式关节角度传感器（IJAT）。 这十通道刺激器的意义，使更多的功能提供。 IJAT和IST的设计和体内评价已经完成。 人体试验正在进行中。

This study is to evaluate the performance of an implantable stimulator system designed to provide activation and control of the paralyzed upper extremity in high level spinal cord injury tetraplegic patients. First generation eight-channel implant receiver stimulators have been implanted in over 100 persons and has received premarket approval from the FDA. We have begun the evaluation of a more advanced, second generation, ten-channel implantable stimulator-telemeter (IST) with an implanted joint angle transducer (IJAT). The significance of this ten-channel stimulator enables more functions to be provided. The design and in-vivo evaluation of the IJAT and IST have been completed. Human trials are proceeding.
