Outline of Research at the Start

視覚性運動錯覚(Visual-motor illusion: VMI)とは身体を安静にしたまま自己の身体運動の映像を観察することで、動いているような運動感覚を感じる運動錯覚法である。VMIは、運動感覚を感じるだけでなく、身体所有感と運動主体感を誘発する。本研究は、健常者を対象に球回し課題によってVMIが運動学習を促進するかを明らかにし、その神経基盤を機能的近赤外分光法(fNIRS)を用いた脳血流量の測定によって探る。

Outline of Final Research Achievements

This study investigated whether VMI changes the early stages of motor learning in healthy individuals. Thirty‐six participants were randomly assigned to two groups: the VMI or action observation condition. Each condition was performed with the left hand for 20 min. The ball‐rotation task and brain activity during the task were measured pre, post1 (immediately), and post2 (after 1 h) in both conditions, and brain activity was measured using functional near‐infrared spectroscopy. The rate of the ball‐rotation task improved significantly at post1 and post2 in the VMI condition than in the action observation condition. VMI condition lowers left dorsolateral prefrontal cortex and right premotor area activity from post1 to pre compared to
the action observation condition. In conclusion, VMI effectively aids early stages of motor learning in healthy individuals.

Academic Significance and Societal Importance of the Research Achievements

視覚性運動錯覚は運動を実施せずに、自己が運動しているような視点で運動を観察することにより錯覚を誘発する方法である。運動を実施せずとも運動機能や脳活動を変化させ運動学習を促進できるため、運動を実施することが困難な脳卒中片麻痺患者や疼痛を有する患者のリハビリテーションに応用できる。
