Outline of Final Research Achievements

The purpose of this study was to develop a new quantitative evaluation method for tactile sensory function using the circulatory regulation function as an index. Therefore, we investigated the responses in cerebral cortex activity and finger blood flow during concentrated finger perception, and examined the learning effect to tactile sensory training on finger circulatory regulation. As a result, it was found that the finger blood flow response to concentrated finger perception was modulated by tactile sensory training. In addition, a similar tendency was observed in cortical activity in the prefrontal cortex. These results show the possibility of developing a new quantitative evaluation method for tactile sensory function using the blood flow response.

Academic Significance and Societal Importance of the Research Achievements

リハビリテーションの臨床現場実施されている感覚機能検査は定性的評価が一般的であり,定量的に示すことが困難である.そのため治療介入の効果判定を詳細に検討することも難しいのが現状である.本研究で示された感覚トレーニングにともなう手指感覚識別機能の変化と血流応答の特性変化の関連性は,感覚機能評価における血流調節機能を指標としたこれまでにない新しい客観的・定量的な評価法の開発の可能性を示すと考える.
