| Outline of Final Research Achievements |
The sensory disturbance caused by finger ischemia was aggravated over time, but was alleviated by tDCS. It was shown that video observation using VR was effective for artificial hand operation training.
A motor synergy analysis of the thumb rotation movement revealed a decrease in CM joint movement and compensatory movement of MP joints in patients with carpal tunnel syndrome compared to normal subjects, and there was no significant difference in synergy in patients with CM arthropathy. However, it was found that the range of motion decreased in all directions. When the reach movement task was analyzed using motion synergy, there was no difference between the left and right hand motion patterns, but there was a difference between the left and right for the pattern involving the shoulder and elbow. It was found that the training extracted from the synergy analysis significantly improved the hand performance.

| Academic Significance and Societal Importance of the Research Achievements |
母指を中心とした運動シナジー解析により，手指の運動パターンの特徴を明らかとし，シナジー解析に基づく訓練が手の機能向上に有効である可能性を示した．また，脳の電気刺激という新たな手法が手指障害の治療に応用可能性があることを示した．VRを用いた上肢リハビリテーションが有効である可能性も示した．
以上の結果は従来あるいは新たなリハビリテーション法に科学的根拠を与え，リハビリテーションの新たな方向を示すことができた．
