We developed the wearable sensorimotor enhance device for fall prevention and investigated an effect for walking of elderly. The experimental results of the plantar tactile enhanced test show that the mechanical vibration noise on the tarsal tunnel by the developed device can enhance the plantar tactile sensitivity. The experimental results of the standing posture stabilizing test and the gait motion test show the device can improved the static and dynamic balance control ability of the elderly subjects. These results suggest that the proposed device has a potential of reducing the risk of fall accident of elderly parson. Furthermore, we also developed the plantar skin deformation measurement system and investigated the plantar skin deformation and variability in young and elderly. The experimental results suggested that the plantar skin deformation measurement can potential to calculate of undetectable walking feature by appearance and screen people who have potential risk of falling.
