Nine tetraplegic patients with C5 or C6 level spinal cord lesions had the Freehand System, an eight channel Functional Electrical Stimulation device, implanted to allow of hand opening and grasp. This paper describes the surgical implementation of the system and the challenges encountered. Seven of the subjects are currently daily users of the device. One subject is unable to use the system due to disruption of bowel function when the system is used. A second subject suffered a lesion of the posterior interosseous nerve, but this was not thought to be related to system use. Additionally, one subject exhibited symptoms of autonomic dysreflexia, which were alleviated by reduction of the strength of the stimulus. Despite such problems, the Freehand system can significantly improve the functional ability of C5 and C6 lesion tetraplegics.
9名患有C5或C6水平脊髓损伤的四肢瘫痪患者植入了“自由手系统”,这是一种八通道功能性电刺激装置,用于实现手部的张开和抓握。本文描述了该系统的手术实施过程以及遇到的挑战。目前,7名受试者每天使用该装置。一名受试者因使用该系统时出现肠功能紊乱而无法使用。另一名受试者发生了骨间后神经损伤,但认为这与系统使用无关。此外,一名受试者出现了自主神经反射异常症状,通过降低刺激强度症状得到缓解。尽管存在这些问题,“自由手系统”仍可显著提高C5和C6损伤四肢瘫痪患者的功能能力。
