Outline of Final Research Achievements |
First, magnetic stimulation compared pain caused by electrical stimulation with the exercise induced by each stimulus, and clarified the superiority of magnetic stimulation in pain. Next, the degree of real-time muscle contraction due to magnetic stimulation was observed using ultrasound imaging and confirmation that magnetic stimulation also induced contraction of muscles located in the deep layer. Although the effect of magnetic stimulation on stiff shoulders could not be verified, we verified shoulder joint movement by electrical stimulation and showed that there is a possibility that electrical stimulation can also cause induction of deep muscles involved in stiff shoulders.

Academic Significance and Societal Importance of the Research Achievements |
末梢に特化した磁気刺激装置は,近年開発された機器である。磁気刺激と比べて小さい痛みでより深層の筋を刺激することが期待できる。本研究成果より,磁気刺激は電気刺激よりも被験者にもたらされる疼痛が低いことを示した。また超音波画像診断装置を用いて磁気刺激中の筋収縮をリアルタイムに観察したことで,磁気刺激による刺激が深層の筋にも刺激効果をもたらすことを示した。
