A versatile two channel stimulator with cutaneous electrodes was designed and built to test the feasibility of multi-channel upper extremity functional electrical stimulation in hemiplegic patients. Preliminary experiments led to the choice of stimulation for hand opening (extensor carpi radialis and ulnaris, extensor digitorum communis) and elbow extension (triceps). Three channel stimulation including the deltoideus muscle was attempted successfully in one patient. Five of eight patients showed substantial improvement with the orthosis and three of these five showed some therapeutic effect over a period of two months. The stimulation was proportionally controlled by the patient by means of movement of the nonaffected shoulder. Functional tasks such as the shifting of an object between two specified areas on a desk were used for evaluation of performance. Tasks that were impossible without stimulation were easily performed with stimulation and after minimal training. The results obtained were significant for the functional rehabilitation of hemiplegic subjects. It is concluded that a more extensive clinical evaluation program including regular long term training of the subjects is justified.
设计并制造了一种带有皮肤电极的多功能双通道刺激器，以测试在偏瘫患者中进行多通道上肢功能性电刺激的可行性。初步实验确定了用于手部张开（桡侧腕伸肌和尺侧腕伸肌、指总伸肌）和肘部伸展（肱三头肌）的刺激。在一名患者中成功尝试了包括三角肌在内的三通道刺激。八名患者中有五名在使用矫形器后有显著改善，这五名患者中的三名在两个月的时间里显示出一定的治疗效果。刺激由患者通过未受影响肩部的运动进行比例控制。诸如在桌子上两个指定区域之间移动物体之类的功能任务被用于评估表现。没有刺激时无法完成的任务在有刺激且经过最少训练后很容易完成。所获得的结果对于偏瘫患者的功能康复具有重要意义。得出的结论是，包括对受试者进行定期长期训练在内的更广泛的临床评估计划是合理的。
