The aim of this study was to investigate a new method of manual acupuncture that used a magnetic field to stimulate only one acupoint vertically. We developed an eight-channel electromagnetic acupuncture (EMA) system that uses a solenoid-type electrode to insert the manual acupuncture needle into a hole in an electrode. We used a manual acupuncture needle for magnetic induction in order to penetrate vertically and deeply into tissues. In order to confirm the usefulness of EMA, we investigated the effects of treatment on muscle fatigue after strenuous knee extension/flexion exercises that had been performed by three groups: the nonstimulation, the manual acupuncture, and the EMA groups. Electromyograms showed that the median frequency (MF) in the EMA group had rapidly recovered after 4 minutes (p = 0.608), but that the peak torque had not recovered to the normal state (p < 0.05). Thus, we confirmed that compared with manual acupuncture, EMA resulted in better recovery from muscle fatigue.
本研究的目的是探讨一种新的手动针刺方法，该方法利用磁场仅垂直刺激一个穴位。我们开发了一种八通道电磁针刺（EMA）系统，该系统使用螺线管型电极将手动针刺针插入电极上的孔中。为了垂直且深入地穿透组织，我们使用了用于磁感应的手动针刺针。为了确认EMA的有效性，我们研究了三组进行剧烈膝关节屈伸运动后治疗对肌肉疲劳的影响：非刺激组、手动针刺组和EMA组。肌电图显示，EMA组的中位频率（MF）在4分钟后迅速恢复（p = 0.608），但峰值扭矩未恢复到正常状态（p < 0.05）。因此，我们证实与手动针刺相比，EMA能使肌肉疲劳更好地恢复。
