Outline of Final Research Achievements

We established an effective visual stimulation method that causes disturbance to the standing posture and examined the effects of visual stimulation on postural control and sensory information processing during periodic floor oscillation. As the rotational angle of the visual stimulation increases and the rotational speed becomes slower, the self-motion illusion occurs, and it was considered that the postural response more occurs. When the visual-motion stimulation was presented during the floor oscillation, young subject did not show remarkable changes in postural stability, whereas elderly showed increased postural fluctuation. In addition, in the elderly, the amplitude of the event related potential at the time of visual stimulation was large, suggesting that the attention to the visual stimulation tended to increase. These results presumably represent a decrease in the ability of multi-sensory re-weighting in the elderly.
