Thus, Timed Up and Go Assessment of Biomechanical Strategies (TUG-ABS) was developed to be able to identify biomechanical strategies while carrying out TUG, and its measurement properties have been investigated for hemiparetic individuals (11). Although commonly used and recommended, the outcome provided by TUG is the time of execution, which is of limited value for diagnoses or planning of treatment, since it fails to identify what is compromised in carrying out the task. (10) as a measure of the time taken by an individual to carry out some functional manoeuvres, such as getting up, gait, turning and sitting down. Of the tests available to evaluate compromised functional mobility in PD, the Timed Up and Go test (TUG) is one of the most used, reported and highly recommended (7–9). These changes are reflected in an increase in flexor tonus and weakness of the extensor muscles, and can be associated with common negative effects on gait ability, such as reduced speed, decreased pace length and decreased arm swing (3–6). Amongst these changes, the most marked are a narrow base and forward inclination of the trunk, internal rotation of the shoulders, and flexion of the hips and knees (3–6). In PD the postural biomechanical changes related to progression of the disease contribute greatly to compromising functional mobility (3). Functional mobility is defined as the ability of a person to move in an independent and safe way in diverse environments and carry out everyday activities, such as locomotion and postural transfers (2). Mobility changes are an inevitable consequence of Parkinson’s disease (PD) and an important cause of reduced quality of life in this population (1). There was a ceiling effect of 22%.Ĭonclusion: TUG-ABS presented adequate measurement properties in individuals with Parkinson’s disease. 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). Results: Considering 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). ![]() Methods: 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. Subjects: Fifty individuals with Parkinson’s disease. ![]() Objective: 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. ![]()
