A B design with subjects acting as their own control when the device is turned off.
Evaluation of the efficacy of the NeuroControl Freehand System.
A supra regional spinal unit in the UK.
The Freehand system is an implanted Functional Electrical Stimulation (FES) device for restoration of lateral and palmar grasps following C5 or C6 tetraplegia. Its use was assessed using the Grasp Relies Test (GRT), Activities of Daily Living (ADL), Grip strength and two-point discrimination.
Seven out of nine subjects are currently daily users of the device. There were statistically significant increases in the number of types of task achieved and the number of repetitions of those tasks in the Grasp Release Test. The system produced a functionally strong grasp where no grip strength at all was possible prior to implantation. Three of the four subjects who had sensory ability prior to implant showed improvements in two-point discrimination. Most of the selected tasks were achieved in the ADL assessment indicating a significant improvement in independence.
The Freehand system can significantly improve the functional ability of C5 and C6 lesion tetraplegics.

评估NeuroControl徒手系统的疗效。
英国一个区域以上的脊髓单位。
徒手系统是一种植入式功能性电刺激（FES）设备，用于恢复C5或C6四肢瘫痪后的侧握和掌握功能。使用抓握依赖测试（GRT）、日常生活活动（ADL）、握力和两点辨别力来评估其使用情况。
9名受试者中有7名目前每天使用该设备。在抓握释放测试中，完成的任务类型数量和这些任务的重复次数有统计学上的显著增加。该系统产生了功能强大的抓握力，而在植入前完全没有握力。4名植入前有感觉能力的受试者中有3名在两点辨别力方面有所改善。在ADL评估中完成了大多数选定的任务，表明独立性有显著提高。
徒手系统可显著提高C5和C6损伤四肢瘫痪者的功能能力。
