| Abstract: | [Purpose] This study aimed to verify the usefulness of a 50-m round walking testdeveloped as an assessment method for walking ability in the elderly. [Subjects] Thesubjects were 166 elderly requiring long-term care individuals (mean age, 80.5 years).[Methods] In order to evaluate the factors that had affected falls in the subjects in theprevious year, we performed the 50-m round walking test, functional reach test, one-legstanding test, and 5-m walking test and measured grip strength and quadriceps strength.[Results] The 50-m round walking test was selected as a variable indicating fall riskbased on the results of multiple logistic regression analysis. The cutoff value of the50-m round walking test for determining fall risk was 0.66 m/sec. The area under thereceiver operating characteristic curve was 0.64. The sensitivity of the cutoff value was65.7%, the specificity was 63.6%, the positive predictive value was 55.0%, the negativepredictive value was 73.3%, and the accuracy was 64.5%. [Conclusion] These results suggestthat the 50-m round walking test is a potentially useful parameter for the determinationof fall risk in the elderly requiring long-term care.Key words: 50-meter round walk test, Local elderly individuals, Falls |
