Abstract

[Purpose] This study aimed to investigate the reproducibility and validity of the 50-m walking test. [Subjects] Reproducibility was investigated in 19 community-dwelling elderly women (mean age, 76.3 years), and validity was investigated in 31 community-dwelling elderly individuals (12 men and 19 women; mean age, 75.7 years). [Methods] The time taken to walk 50 m, the time taken to walk each 10-m section (laps 1–5), the time taken to walk 10 m, and grip strength were measured. In addition, the functional reach test (FRT), one-leg standing test, and timed up and go (TUG) test were performed. [Results] In a reproducibility analysis, the interclass correlation coefficient (1,1) was 0.97. In a Bland-Altman analysis, no systematic error was found. The measured values from the 50-m walking test included a measurement error of 1.5 s, and the acceptable margin of error was confirmed to be 3.1 s. In a validity analysis, the 50-m walking test score was significantly correlated with the 10-m walking and TUG test scores. [Conclusion] Our results suggest that the 50-m walking test score may be a useful index of the walking ability of community-dwelling elderly.
