A difficulty due to the central nerve paralysis caused by spinal cord injury due to the traffic accident, cerebral hemorrhage, cerebral apoplexy by brain infarction, is recently on the increase. There are many cases that peripheral nerves and muscles are normal with these difficulties.An electric stimulation was given to peripheral nerves and muscles for such patients, and the trial of gait restoration was made. However, a large-scale device so for and professional operators were needed. Moreover, it could not cope with a long time due to muscle fatigue. Because only the stimulus programmed in advance could be done, the electric stimulation of the same intensity, even when the muscular contraction power was changing.We manufactured an electric stimulation device that was small in size and its use was easy. The device gave an electric stimulation while monitoring muscle fatigue with on-line. (2000)Furthermore, a device was miniaturized to the size of mounting in a knee supporter for spo … More rt. Then, it tried so that it could hide a device in patient's trousers and skirts. Commercial electric power should not be necessary, and a device made that it was necessary so far that it could do enough electric stimulation in 1 dry cell of 9V. (2001)In 2002, we manufactured a device for patients whose EMG from their tibialis anterior muscle (TA) but who could not dorsiflex their ankle joints. The device gave electric stimulation when it detects the patients small EMG. The size of the device was 10 x 6 x 2cm. and it worked with three unit-3 dry cells. It was made to don and doff the patients themselves easily by interwoven the electrodes in the knee supporter. The electrodes were attached to the common peroneal nerve and the muscle belly of TA automatically. When small EMG was observed from TA, a stimulation was given to TA, to made to dorsiflex a foot join. The patient whom this device will be more useful for from now on will be extracted, and a clinical experiment will be continued to proceed with the improvement of the device. Less

近年来，交通事故引起的脊髓损伤、脑出血、脑梗塞引起的脑中风等引起的中枢神经麻痹的病症日益增多。很多情况下，周围神经和肌肉正常，但出现这些困难。对此类患者进行周围神经和肌肉电刺激，尝试恢复步态。然而，需要大型设备和专业操作人员。而且，由于肌肉疲劳，它无法应对长时间的工作。因为只有预先编程的刺激才能完成，即使肌肉收缩力发生变化，也能产生相同强度的电刺激。我们制造了一种体积小、使用方便的电刺激装置。该设备提供电刺激，同时在线监测肌肉疲劳程度。 (2000) 此外，一种装置被小型化至安装在膝盖支撑器中的尺寸，以用于 spo … 更多 rt。然后，它尝试将设备隐藏在患者的裤子和裙子中。应该不需要商业电源，并且迄今为止需要用1个9V的干电池进行足够的电刺激的装置。 (2001) 2002 年，我们为那些通过胫骨前肌 (TA) 进行肌电图检查但无法背屈踝关节的患者制造了一种设备。当该设备检测到患者的微小肌电图时，就会发出电刺激。该装置的尺寸为10 x 6 x 2cm。它可与三块 3 号干电池配合使用。通过将电极交织在护膝中，患者可以轻松地自行穿脱。电极自动连接到腓总神经和TA的肌腹。当从 TA 观察到小肌电图时，对 TA 进行刺激，使足背屈。今后将抽取该装置更有用的患者，并随着该装置的改进继续进行临床实验。较少的
