Outline of Final Research Achievements

Humans are thought to regulate a stable gait by integrating their own localization information and spatial information from the outside world. However, the relationship between visuospatial cognitive function and postural control have not been fully established. To clarify this relationship, this study attempted to focus on stereopsis from a neurophysiological and psychophysical perspective. The findings of the present study showed that a decrease in brain information processing of stereopsis in healthy adults affects body sway during walking.

Academic Significance and Societal Importance of the Research Achievements

歩行中の身体動揺が立体視の脳内情報処理の低下によって引き起こされる可能性があることから、将来、視空間認知を高めるための脳可塑性を誘導するニューロリハビリテーションの提案やトレーニング機器の開発へと役立つ。このことは、転倒発生率の低下ならびに転倒問題に派生する医療経済的負担の抑制につながる可能性がある。
