Gait Restoration of Paraplegia using Functional Electrical Stimulation

最近，因交通事故造成的脊髓损伤导致中枢神经麻痹、脑出血、脑梗塞引起的脑中风等引起的困难正在增加。有许多病例周围神经和肌肉在这些困难下是正常的。对患者周围神经和肌肉进行电刺激，并进行步态恢复试验。然而，需要大型设备和专业操作人员。此外，由于肌肉疲劳，它不能应付长时间。因为只有事先设定好的刺激才能完成，同样强度的电刺激，即使是在肌肉收缩力发生变化的时候。我们制造了一种体积小、使用方便的电刺激装置。该装置在监测肌肉疲劳的同时进行电刺激。（2000）进一步，将一种装置缩小到可以安装在膝盖支架上的大小，以供病人使用……更多的研究。然后，它尝试将装置隐藏在病人的裤子和裙子里。商业电力不应该是必要的，到目前为止，一种装置使它成为必要的，它可以在一个9V的干电池中产生足够的电刺激。（2001） 2002年，我们为不能背屈踝关节的胫骨前肌（TA）肌电图患者制造了一种装置。当检测到患者的小肌电图时，该装置会给予电刺激。该装置的尺寸为10 x 6 x 2cm，使用3个unit-3干电池。通过将电极编织在膝盖支架上，病人可以很容易地自己穿脱。电极自动附着于腓总神经和TA肌腹。当观察到TA的小肌电图时，对TA进行刺激，使其背屈一个足关节。将取出今后对该装置更有用的患者，并继续进行临床实验，对装置进行改进。少

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
