timed up and go test validity and reliability

The TUG is used frequently in the elderly population, as it is easy to administer and can generally be completed by most older adults. During the test, the person is expected to wear their regular footwear and use any mobility aids that they would normally require. It uses the time that a person takes to rise from a chair, walk three metres, turn around, walk back to the chair, and sit down. It has previously been described as a reliable tool to evaluate objective functional impairment in patients with lumbar degenerative disc disease. The Timed Up and Go test (TUG) is a simple test used to assess a person's mobility and requires both static and dynamic balance. TUG-ABS presented adequate measurement properties in individuals with Parkinson's disease.Clinical studies on patients with lumbar degenerative diseases increasingly employ objective measures of function, which offer high potential for improving the quality of outcome measurement in patient- care and research. One-way analysis of variance (ANOVA) showed that TUG-ABS discriminated the individuals with Parkinson's disease in all stages according to Hoehn & Yahr. The discriminant function obtained with the total score of TUG-ABS classified 60% of the individuals correctly with respect to the group (determined by the performance in TUG) to which they belonged. Significant, elevated and positive correlations were obtained between TUG-ABS and the Balance Evaluation System Test (BESTest)-VI (ρ = 0.72) and negative correlations between TUG-ABS and TUG (ρ = -0.78). The construct validity between the TUG-ABS and the Unified Parkinson's Disease Rating Scale (UPDRS) - part III was classified as moderate (ρ = -0.62). The minimal detectable change was 3.82 points. The TUG-ABS presented excellent internal consistency (α = 0.98).

The study investigated the following properties: reliability (inter-examiner, intra-examiner, test-retest, internal consistency and minimal detectable change), construct validity, and floor and ceiling effect.Ĭonsidering the total score, the inter-examiner, test-retest and intra-examiner reliabilities were classified as excellent (0.95 ≤ intra-class correlation coefficient (ICC)≤0.99). To investigate the measurement properties of the Timed Up and Go Assessment of Biomechanical Strategies (TUG-ABS) to determine its adequacy for use with individuals with Parkinson's disease.įifty individuals with Parkinson's disease.
