Evaluating toe flexor strength may be an important method for predicting and preventing walking dysfunction and falls, particularly among older adults. In this study, toe grip strength (TGS), the functional reach (FR, a measure of dynamic balance) test, the timed up and go (TUG) test (a measure of functional ability), isometric knee extension strength (IKES), sex, age, weight, and height were analyzed among 665 healthy Japanese older adults. Statistical analyses were used to assess the relationships between TGS and FR or TUG and to investigate whether TGS was independently associated with FR or TUG. Our results indicate that, among both men and women, TGS was associated with TUG, independent of age, height, weight, and IKES, but TGS was not associated with FR. These results may facilitate the development of strategies for improving functional mobility through physical therapy.

The purpose of this study was to investigate the relationship between muscle strength asymmetry and body sway while walking. We studied 63 older adult women. Strong side and weak side of knee extension strength, toe grip strength, hand grip strength, and body sway while walking were measured. The relationship between muscle strength asymmetry for each muscle and body sway while walking was evaluated using Pearson’s correlation coefficient. Regarding the muscles recognized to have significant correlation with body sway, the asymmetry cutoff value causing an increased sway was calculated. Toe grip strength asymmetry was significantly correlated with body sway. Toe grip strength asymmetry causing an increased body sway had a cutoff value of 23.5%. Our findings suggest toe grip strength asymmetry may be a target for improving gait stability.
