Aims:
It is aimed to investigate the psychometric properties of Mini-BESTestTR in Turkish patients with neurological disorders.
Methods:
A total of 61 people between the ages of 42 and 80, who were patients with Parkinson's disease, stroke or multiple sclerosis for more than 1 year, were included in the study. For inter-rater reliability, two independent researchers applied the scale two times within 5 days for test-retest reliability. The relationship of mini-BESTestTR with Berg Balance Scale (BBS) to assess concurrent validity, and Timed Get up and Go (TUG), Functional Reach Test (FRT) and Functional Ambulation Classification (FAC) for convergent validity was investigated.
Results:
The scores of the two evaluators were within the range of agreement (mean = - 0.278 ± 1.484, p > 0.05), and the Mini-BESTestTR had excellent inter-rater reliability [ICC (95% CI) = 0.989 (0.981-0.993)] and test-retest reliability [ICC (95% CI) = 0.998 (0.996-0.999)]. Mini-BESTestTR had a strong correlation with BBS (r = 0.853, p < 0.001) and TUG (r = - 0.856, p < 0.001), had a moderate correlation with FAC (r = 0.696, p < 0.001) and FRT (r = 0.650, p < 0.001).
Conclusions:
Mini-BESTestTR showed significant correlations with other balance assessment measures, and concurrent and convergent validity of Mini-BESTestTR was demonstrated when administered to a sample of patients with chronic stroke, Parkinson's disease and multiple sclerosis.
