Outline of Final Research Achievements

In this project, we examined the relationship between the misperception of the directions of gravity or body longitudinal axis and postural disorder in stroke patients and explored the brain regions involved in the misperception of these directions. We found that the stability in the estimates of the directions of gravity and body axis in the upright position correlated with the static balance ability. The brain imaging analysis revealed that the lesion in the temporal region may be involved in the misperception of the directions of gravity and body axis. These findings suggest that misperception of the directions of gravity or body axis would be a factor in postural disorders in stroke patients, and can contribute to our understanding of the neural basis of spatial orientation.

Academic Significance and Societal Importance of the Research Achievements

脳卒中患者における方向認知障害と姿勢障害の関連性や方向認知障害に関わる神経基盤について実験的に検討した研究は少なく、その詳細は未だ不明であった。本課題によって得られた知見は、脳卒中患者の方向認知障害の基礎理解を促進するとともに、姿勢障害の改善を目的とした新たなリハビリテーション介入の開発に繋がる可能性がある。
