Abstract
The purpose of this study was to investigate the relationship between muscle strength asymmetry and body sway while walking. We studied sixty-three 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 cut-off 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 cut-off value of 23.5%. Our findings suggest toe grip strength asymmetry may be a target for improving gait stability.
