| Outline of Final Research Achievements |
In this international collaboration project, we investigated effects of expertise and development of neurological disorders on fine motor control through a comparative study between pianists with different skill levels and pianists with task-specific focal dystonia. The results demonstrated malfunctions of feedforward control of movements in association with focal dystonia and improvement of somatosensory-motor integration functions in pianists compared with unskilled individuals. In addition, we developed and assessed a prototype of diagnosis system of focal dystonia based on camera images.

| Academic Significance and Societal Importance of the Research Achievements |
脳神経系は学習や過剰訓練に伴い機能を変化する可塑性を有する．しかし，可塑性が技能の獲得や洗練，失調に及ぼす影響は十分に明らかにされていない．本国際共同研究は，異なる生体状態にある群の技能や中枢神経機能を比較することで，脳神経可塑性と技能の関連についての新しい知見を創出した．これらの知見は，教育プログラムやリハビリテーションの開発といった社会的意義を生み出す潜在性を有する．
