This paper describes a clinical randomized single-blinded study of the effects of Functional Electrical Therapy (FET) on the paretic arms of subjects with acute hemiplegia caused by strokes. FET is an exercise program that comprises voluntary arm movements and opening, closing, holding, and releasing of objects that are assisted by a neural prosthesis (electrical stimulation). FET consisted of a 30 min everyday exercise for 3 consecutive weeks in addition to conventional therapy. Twenty-eight acute hemiplegic subjects participated in a 6 mo study. The subjects were divided into lower functioning groups (LFGs) and higher functioning groups (HFGs) based on their capacity to voluntarily extend the wrist and fingers against the gravity, and were randomly assigned to controls or FET groups. The outcomes included the Upper Extremity Function Test, the coordination of elbow and shoulder movements, spasticity of key muscles of the paretic arm, and Reduced Upper Extremity Motor Activity Log. FET and control groups showed a recovery trend in all outcome measures. The gains in FET groups were much larger compared with the gains in control groups. The speed of recovery in FET groups was substantially faster compared with the recovery rate in control groups during the first 3 weeks (treatment). The LFG subjects showed less improvement than the HFG in both the FET and control groups.
本文描述了一项关于功能性电疗法（FET）对中风所致急性偏瘫患者患侧上肢影响的临床随机单盲研究。FET是一种运动方案，包括在神经假体（电刺激）辅助下的患侧上肢自主运动以及物体的开合、握持和松开动作。FET除了常规治疗外，还包括连续3周每天30分钟的锻炼。28名急性偏瘫患者参与了一项为期6个月的研究。根据患者对抗重力自主伸展手腕和手指的能力，将患者分为功能较低组（LFGs）和功能较高组（HFGs），并随机分配至对照组或FET组。观察指标包括上肢功能测试、肘和肩部运动协调性、患侧上肢关键肌肉的痉挛情况以及上肢运动活动减少日志。FET组和对照组在所有观察指标上均呈现恢复趋势。与对照组相比，FET组的改善幅度更大。在最初3周（治疗期），FET组的恢复速度明显快于对照组。在FET组和对照组中，LFGs患者的改善均不如HFGs患者。
