Abstract
Timed Up & Go test (TUG) strongly relates to lower muscle strength, equilibrium function and activity of daily living. Subjects tested were 188 female over the age of 65, who participated in the school of bedridden prevention. The purpose of this study is to investigate the physical function that affects TUG. The variables of this study were age, BMI, one-leg standing time, 5m straight course time, and hand grip strength. In statiscal analysis, simple correlation coefficient with TUG and the variables were calculated by simple linear regression analysis to find relationship. The variables that showed significant correlations with TUG are one-leg standing time, 5m straight course time, and hand grip strength. The age of subjects and BMI are not significantly correlated. Among the items which are significantly correlated with TUG, one-leg standing time is the only item that showed a standardized partial regression coefficient. Although several reports explained the relationships with TUG, age and BMI, this particular study did not show the same results. The equilibrium function is necessary for the movements of turning, standing and sitting in TUG. Therefore this study suggests that maintaining equilibrium function may improve TUG results.
