项目摘要

The method of pulsed magnetic stimulation has become of major interest lately in the field of therapy for Parkinson's disease or rehabilitation. In the territory of clinical science, however, magnitude or method of magnetic stimulation is not well known. A strong magnetic stimulation is devotedly used in current therapy. Moreover, the target of the mechanism of stimulation effect is forcality of stimulation, but it is not yet cleared.In this study, we aimed at the development of new magnetic stimulation for recovery of muscle fatigue, noticing the distribution of eddy current in the human body. In 2006, a quantitative measurement method of fatigue is established on basis of the experimental data in 2004 or 2005.According to the recovery effect for muscle fatigue, weak magnetic stimulation inhibits the decrement of maximum voluntary contraction (MVC) at the rate of 90% in every subjects. These results suggest that weak magnetic stimulation has promoted the recovery for muscle fatigue. We also developed the flexible magnetic coil and the instrument for restoration of fatigued muscle. However we could not yet estimate the developed instrument. As a future subject, we quantitatively investigate the recovery effect for muscle fatigue.

脉冲磁刺激的方法已成为最近在治疗帕金森病或康复领域的主要兴趣。然而，在临床科学领域，磁刺激的强度和方法尚不清楚。在电流治疗中专门使用强磁刺激。此外，刺激效应机制的目标是刺激的强迫性，但尚未明确。在这项研究中，我们着眼于开发新的磁刺激来恢复肌肉疲劳，注意到涡流在人体中的分布。2006年，在2004、2005年试验数据的基础上，建立了疲劳定量测量方法。从肌肉疲劳的恢复效果来看，弱磁刺激对最大随意收缩（MVC）的抑制率为90%。提示弱磁刺激能促进肌肉疲劳的恢复。我们还开发了柔性磁线圈和修复疲劳肌肉的仪器。然而，我们还不能估计已开发的仪器。作为一个未来的课题，我们定量地研究肌肉疲劳的恢复效果。
