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 acupunc- ture needle for magnetic induction in order to penetrate vertically and deeply into tis- sues. 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.
