| Outline of Final Research Achievements |
Peripheral magnetic stimulation (PMS) is a novel neurorehabilitation technique for sensorimotor dysfunction after stroke. In the present study, we found following three new insights in healthy participants. (1) Short term session of repetitive PMS (rPMS) combined with motor imagery enhances the corticospinal excitability, (2) Corticospinal excitability of antagonist muscle is increased immediately after rPMS combined with motor imagery, and (3) Click sounds facilitates somatosensory stimulus detection during rPMS.

| Academic Significance and Societal Importance of the Research Achievements |
rPMSと運動イメージの併用については，随意運動中のrPMSについて検討する上での基礎的なデータとなるだけでなく，随意運動が困難である重度運動麻痺を呈する脳卒中患者のリハビリテーションへの応用が期待できる研究内容である．また，rPMSのクリック音については，磁気刺激に特有な刺激時に発生する音（クリック音）に着目している．rPMSのクリック音の影響を明らかにすることで，PMSの臨床応用を検討する上での基礎的なデータとなりうる知見である．
