BACKGROUND: The Timed Up and Go (TUG) test is quick and easy tests to assess @entity1 ' functional mobility. However, its reliability in individuals with @entity626 ( @entity571 ) has not been well established. The aims of this study were to determine the reliability and minimal detectable change of the TUG test in individuals with doubtful to moderate (Grade 1-3) knee @entity571 . METHODS: Sixty-five subjects (25 male, 40 female), aged 45-70 years, with knee @entity571 participated. Inter-rater reliability was assessed using two observers at different times of the same day in an alternating order. Intra-rater reliability was assessed on two consecutive visits with a 2-day interval. The standard error of measurement (SEM) and the minimum detectable change (MDC) were calculated to determine statistically meaningful changes. RESULTS: Intra-rater and inter-rater reliability were 0.97 (95  % confidence interval [CI], 0.95 - 0.98) and 0.96 (95  % confidence interval [CI], 0.94 - 0.97), respectively. The MDC, based on measurements by a single rater and between raters, was 1.10 and 1.14  seconds, respectively. CONCLUSIONS: The TUG is a reliable test with adequate MDC for clinical use in individuals with doubtful to moderate knee @entity571 .
