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.
