| Research Abstract |
In this study, I made a prototype of interferential current (IFC) stimulator to explore the availability of IFC stimulation method in a development of behavior support equipment aimed at preventing falls in the elderly. I examined whether a very small current stimulus with IFC improve the equilibrium function. Body sway did not reduce with IFC stimulus on the surface of the gastrocnemius muscle. This result suggests that IFC stimulation with a weak current influence the muscle spindle due to a current effect of IFC stimulation occurs in deep, not directly beneath of skin. In contrast, IFC stimulation applied to the knees joint in both legs, the reduction of body sway was confirmed.
