Description

[Purpose] The object of this study was to investigate the effects of an arch support insole on the toe flexor muscle function during standing?. [Subjects] The subjects were 22 healthy male students. [Methods] The standing on one leg test was performed by all subjects with and without weight-bearing arch support insoles, and the standing time, movement trace of the vertical component of the center of gravity of the body, and the pinch power of the big and second toes were measured. [Results] The pinch power corresponding to toe flexor muscle strength and the standing time due to instability of the body significantly decreased when using the the insole. Furthermore, a tendency for increased movement of the vertical component of the center of gravity was also seen when using the insole, compared to without it. [Conclusion] The results suggest the possibility that an arch support insole might increase the risk of falling, since the arch function depends on the toe flexor muscle strength. <br>
