BACKGROUND: There are few objective measures of functional impairment to support clinical decision making in @entity1798 ( @entity179 ). OBJECTIVE: We present the validation (and reliability measures) of the Timed Up and Go (TUG) test. METHODS: In a prospective, 2-center study, 253 consecutive @entity1 were assessed using the TUG test. A representative cohort of 110 volunteers served as control subjects. The TUG test values were assessed for validity and reliability. RESULTS: The TUG test had excellent intra- (intraclass correlation coefficient: 0.97) and interrater reliability (intraclass correlation coefficient: 0.99), with a standard error of measurement of 0.21 and 0.23 seconds, respectively. The validity of the TUG test was demonstrated by a good correlation with the Visual Analog Scale (VAS) back (Pearson's correlation coefficient [PCC]: 0.25) and VAS (PCC: 0.29) leg @entity2531 (Roland-Morris Disability Index [PCC: 0.38] and @entity717 Index [PCC: 0.34]), as well as with health-related quality of life (Short Form-12 Mental Component Summary score [PCC: -0.25], Short Form-12 Physical Component Summary score [PCC: -0.32], and EQ-5D [PCC: -0.28]). The upper limit of "normal" was 11.52 seconds. Mild (lower than the 33rd percentile), moderate (33rd to 66th percentiles), and @entity73 (higher than the 66th percentile) as determined by the TUG test was <13.4 seconds, 13.4 to 18.4 seconds, and >18.4 seconds, respectively. CONCLUSION: The TUG test is a quick, easy-to-use, valid, and reliable tool to evaluate objective functional impairment in @entity1 with @entity1798 . In the clinical setting, @entity1 scoring a TUG test time of over 12 seconds can be considered to have functional impairment.
