Outline of Final Research Achievements

Focusing on the important role of motor relearning in the recovery of motor function from brain injury, we will construct a new noninvasive brain stimulation method to promote recovery in stroke hemiplegia. Currently, the regions that promote motor relearning in stroke hemiplegics have not been fully identified. Identification of the stimulation areas that promote motor learning may lead to the development of more effective methods to promote functional recovery. Therefore, this study will develop a model of impaired motor learning function in healthy adults and use this model to identify the stimulus areas that promote motor relearning. This research will establish a foundation for systematizing both theoretical and experimental methods of stimulating hemiplegic symptoms in stroke patients to recover more rapidly and to a greater extent.

Academic Significance and Societal Importance of the Research Achievements

脳血管疾患はその療養が長期に及ぶことが多く、介護費用は2兆円を超え、総介護費用の29％もの割合を占めるため、脳血管疾患を持つ多くの患者の機能回復を促進し、自立して日常生活を送るための新たな治療法の構築が必要である。そこで本研究は、運動機能回復には運動の再学習が重要な役割を担っている点に着目し、脳卒中片麻痺の回復を促進する新たな刺激法の開発へと展開するための基盤研究を行う。運動の再学習を促進する刺激法を確立することは、効果的な治療法の開発に貢献できると考えている。
