Outline of Final Research Achievements

The purpose of this study is to develop a sound source localization task using hearing and examine its usefulness for patients with unilateral spatial neglect.In this study, a randomized controlled trial of left USN patients,Changes in cerebral hemodynamics in sound source localization tasks of healthy subjects were confirmed by near-infrared spectroscopy. As a result of examining by this task in 10 healthy adults and 19 USN patients, the usefulness of the sound source localization task was suggested.

Academic Significance and Societal Importance of the Research Achievements

本研究は，半側空間無視(USN)に対し音源定位を用いた介入効果を検証した新しい取り組みであった．結果として一部ではあるがその有用性が示唆された．したがって，本研究の成果は今後のUSNのさらなる治療や研究の発展に貢献できるものである．USNは，脳卒中による高次脳機能障害の代表的な病態であり，様々な角度からこの治療に関わることが求められている．したがってUSNに対するリハビリテーションの発展は，多くの対象者のQOLの向上に寄与すると考えられる.
