Outline of Final Research Achievements

In this study, the factors of slippage of the foot that make the posture unstable were quantitatively investigated as a basic study related to fall prevention on winter roads. A system that simulatively reproduces the slippage of the foot was designed and constructed. Then, it was confirmed whether the acceleration and the moving distance of the stage moving the foot can be accurately presented according to the setting. In the next experiment, the subjects orally answered whether or not the posture could be kept stable after presenting the perturbations. The results of this study suggested that the relationship between the acceleration and the moving distance of the foot was suggested when the posture becomes unbalanced although there is an individual difference.
