Objectives:
Given that body composition assessment is becoming more common, demonstrating the significance of assessing muscle mass asymmetry, which has not been a focus in the past, would be important. This study examined the association between the leg skeletal muscle mass asymmetry index (LSMAI) and the timed up-and-go (TUG) test to assesses dynamic postural control capabilities, in community-dwelling older adults.
Methods:
This study is a cross-sectional study. The study had 122 (75 ± 6 years, 74% female) participants who fulfilled the required sample size. A generalized linear model was used to examine the association between the TUG and the LSMAI.
Results:
An association was found between the TUG and LSMAI (standard regression coefficient, 0.21, p = .022). As with the crude model, a significant association was found between TUG and LSMAI in the adjusted model (standardized coefficient = 0.31, p = .009).
Conclusions:
Assessing LSMAI in older adults is crucial. Moreover, this finding indicates the need to consider LSMAI in maintaining the dynamic posture control capabilities of older adults.
Implications:
The new finding that LSMAI in older adults is associated with TUG emphasizes the need for assessment and intervention of LSMAI. This suggests that the approach to LSMAI may contribute to maintaining and improving dynamic posture control ability.
