| Outline of Final Research Achievements |
In hemiplegic stroke patients, the strength of activity of the anterior deltoid fibers, which are the leading muscles of shoulder flexion, and the strength of activity of the biceps brachii, pectoralis major, and other muscles associated with abnormal muscle synergy in stroke patients were found to be independent factors.
It was also proved that optimal assistance during exercise in stroke patients did not reduce the muscle activity of the deltoid muscle.
Next, we conducted an intervention to verify the effect of robotic rehabilitation on shoulder dysfunction. For shoulder elevation dysfunction in chronic stroke patients, we performed gravity-assisted shoulder elevation training with a robot and showed improvement in motor function.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、１，「筋力」ではなく「筋協調（筋シナジー）」に着目しており、２．１に基づく「適切な量の介助」を行うことで運動学習を促進を行っている、さらに３．難易度が高い肩関節屈曲運動をターゲットにしている、ということで革新的でありながら、理論的に汎用性が高い。また、脳卒中による運動麻痺患者の対象者の多さからも、それらの方々の運動機能改善、社会復帰に寄与することが期待される。
