Objectives: Locomotive syndrome (LS) is a condition requiring nursing care for musculoskeletal disorders. Our aim was to evaluate the correlation between body composition, measured by bioelectrical impedance analysis (BIA), and LS, measured using the 25-question Geriatric Locomotive Functional Scale (GLFS-25). Methods: We enrolled 286 individuals who were undergoing regular health follow-up. All individuals completed the GLFS-25, body composition analysis by BIA, and five physical performance tests related to LS: timed up-and-go test, 10-m gait time, maximum stride length, back strength, and grip strength. Measured variables and demographic data were compared between individuals with and without LS. Results: The extracellular water ratio, the extracellular water/total body water (ECW/TBW) ratio differentiated the LS and non-LS groups (p=.005), with all physical function measures being lower among individuals with a high, compared to low, ECW/TBW ratio. The risk ratio for LS among individuals with a high ECW/TBW ratio was 2.31, with an odds ratio of 2.67. Conclusion: The ECW/TBW ratio is predictive of LS. Based on our results, we propose that BIA should routinely be performed, with follow-up and intervention, as needed, for individuals with a high ECW/TBW ratio, as they are at risk for developing LS.
