Quantitative assessment of locomotive syndrome by the loco-check questionnaire in older Japanese females

Abstract

[Purpose] Locomotive syndrome (LS) is a condition by which older people may require care service because of problems with locomotive organs. This study examined whether the loco-check, a 7-item questionnaire, is useful for quantitatively assessing the severity of LS. [Subjects and Methods] Seventy-one community dwelling Japanese females aged 64-96 years (81.7 ± 8.0 years) participated in this study. The associations of the loco-check with thigh muscle mass measured by X-ray CT, physical performance, nutritional status, and quality of life (QOL) were investigated. [Results] The results showed that the number of times that "yes" was selected in the loco-check was significantly correlated with thigh muscle mass, major measures of physical performance, nutritional status, and QOL. This number was also significantly larger in the participants experiencing falling, fracture, and lumbar pain than in those without these episodes. [Conclusion] These results suggest that the loco-check might be useful for quantitatively evaluating LS.
