Objective: The aim of this study was to examine the relationship between left-right difference of one-leg standing time and severity of locomotive syndrome among community-dwelling older people. Methods: A total of 1211 community-dwelling older people participated in our study at 2017. One-leg standing times were measured and the subjects were divided into three groups depending on differences between left and right leg time values: no difference (A), difference of less than 10 seconds (B), and

... difference of more tha n 10 seconds (C). The severity of locomotive syndrome was assessed by the self-assessment questionnaire "locomo-5". The percentage of subjects who tested positive for locomotive syndrome was compared in the three groups, and according to the maximum one-leg standing time values of less than 15 seconds, 15 seconds and more to less than 60 seconds, and 60 seconds. Risk ratios were calculated for positive versus negative of locomotive syndrome. Results: The proportion of subjects with locomotive syndrome among the group with the maximum one-leg standing time of 60 seconds showed a significant difference between group A (6.4%) and group C (12.8%) (p=0.030). For the 60 seconds maximum standing leg-time group, the risk ratio was 1.76 in group C versus group A (p=0.040). In the other maximum one-leg standing time groups, the results were not statistically significant. Conclusion: Among the older people with one-leg standing time of 60 seconds, the left-right differences in oneleg standing time was positively associated with the severity of locomotive syndrome.
