There is the increasing concern of the society to prevent the tumbling of the aged. The study of the static, as well as dynamic aspects, such as the muscular strength of the lower-limb and the postural stability, should be developed, especially from the viewpoint of the aged. This paper focuses on the external observation of the foot and toenail, as being correlated to the physical functions of the lower-limb against tumbling. The lower-limb functions are evaluated in terms of the 10 m walking time, the toe-gap force and single-foot standing period. The correlation to the personal tumbling experiences is also examined. It is seen that the groups, which exhibit external abnormalities in the foot and the toenail, generally decline in the muscular strength and postural stability. They also have more frequent tumbling experiences and express in their concern of the danger of tumbling. It seems that those shapes abnormalities can indicate, to some extent, the tumbling danger of the aged.

The aim of this study was to evaluate the postural control ability using stabilogram-diffusion analysis (SDA). Any parameters of SDA were compared with several parameters of body sway derived from recordings of the center of pressure (COP) with the aid of a static force platform. The subjects were 38 elderly healthy volunteers. They quietly stood on a static force plat form with open and closing eyes. As the results, there was a significant correlation between the diffusion constant derived from the parameters of SDA and the parameters of COP with eyes open and closed. The correlation was found to be greater in the closing eye condition than that in the open eye condition. The correlations between diffusion coefficients and the range and mean of anterior-posterior velocity were greater than the correlations between the diffusion coefficients and the range and mean of the lateral velocity. Thus, the muscle of the tibialis anterior and the planter muscles was suggested.
