Outline of Final Research Achievements

The purpose of this research is to investigate the effects of noisy current stimulation of the vestibular organs on balance function in the elderly. The results of the present study revealed that the center of pressure (COP) sway in community-dwelling elderly people was significantly reduced during vestibular noise current stimulation. Furthermore, it was clarified that the stimulatory effect that the vestibular noise current stimulation significantly reduces the COP sway is higher in elderly people who have higher COP sway before stimulation. In addition, the present study revealed that the COP sway continued to decrease not only during vestibular noise current stimulation, but also after stimulation.

Academic Significance and Societal Importance of the Research Achievements

高齢者の転倒予防に関しては,運動療法(筋力トレーニングやバランストレーニング)が中心的に行われている.本研究において,バランスに関与する前庭器官に微弱なノイズ電流刺激を行うことで,高齢者のバランス機能が即時的に向上することが明らかとなった.さらに,前庭器官へのノイズ電流刺激の効果は刺激中だけでなく,刺激終了後にも持続することも明らかとなった.これらの知見より,前庭器官へのノイズ電流刺激は,高齢者のバランス機能を向上させる新たな治療法となり得る可能性を示唆しており,高齢者の転倒予防に貢献する可能性がある.
