| Outline of Final Research Achievements |
We constructed a system to modify neural activity using functional near infrared spectroscopy (fNIRS). As a result of performing the search task of visual condition and vibration condition for healthy people and stroke patients, individual difference was recognized only in vibration condition. We also measured the prefrontal activity during the task using fNIRS, and showed that the brain base reflected by the individual differences is the dorsolateral prefrontal cortex. We constructed a neurofeedback system using fNIRS as a new method to intervene in the function of this dorsolateral prefrontal area, and implemented it in individuals with acute stroke patients with hemiplegia. As a result, individuals with higher brain function have dorsolateral prefrontal activity A tendency to rise is obtained (n = 20, difference between groups p = 0.072).

| Academic Significance and Societal Importance of the Research Achievements |
脳卒中患者に伴う運動機能障害に対するリハビリテーション効果を促進する手法の確立は、解決が求められている問題の一つである。ニューロフィードバックはリハビリテーションの一手法であるが、その訓練効果に個人差が大きいことも指摘されている。本研究では、ニューロフィードバック訓練に伴う運動機能改善効果の関係性とその個人差が明らかとなれば、患者個々人の神経系特性を考慮した新しいリハビリプロトコルの確立につながることが期待される。最終的には、患者の早期社会復帰に貢献することが期待される。
