Restoration of hand function through functional electrical stimulation allows tetraplegic patients to use existing abilities to control paralyzed muscles. In patients with C5 or C6 spinal cord injuries, implanted upper extremity neuroprostheses use functional electrical stimulation technology to power hand and arm muscles. A variety of devices, often using contralateral shoulder motion, sends signals via a small external controller and transmitting coil to an implanted stimulator. The stimulator powers designated upper extremity muscles via implanted electrodes. The surgical procedure is minimally invasive and easily reversed. Palmar and lateral grasp, among other functions, can be reliably restored, leading to significant improvements in functional capacity. High user satisfaction, low complication rates, and recent advances in technology and control systems contribute to the success of this technology in the treatment of devastating spinal cord injuries.
通过功能性电刺激恢复手部功能,使四肢瘫痪患者能够利用现有能力控制瘫痪肌肉。对于C5或C6脊髓损伤患者,植入式上肢神经假体利用功能性电刺激技术为手部和手臂肌肉提供动力。多种设备通常利用对侧肩部运动,通过一个小型外部控制器和发射线圈将信号发送到植入式刺激器。刺激器通过植入电极驱动指定的上肢肌肉。该手术过程微创且易于逆转。除其他功能外,掌侧和外侧抓握功能可得到可靠恢复,从而显著提高功能能力。高用户满意度、低并发症发生率以及技术和控制系统的最新进展促成了这项技术在治疗严重脊髓损伤方面的成功。
