The 2 scales behave similarly, but the Mini-BESTest appears to have a lower ceiling effect, slightly higher reliability levels, and greater accuracy in classifying individual patients who show significant improvement in balance function.The aim of this study was to investigate if the 7–item Berg balance scale (BBS) 3–point, which is a short form of the BBS (SFBBS), has compatible psychometric properties in comparison with the original BBS, and also to study the concurrent validity using a 10-meter walk test (10mWT) and a timed up and go test (TUG), which are widely used with SFBBS in clinical settings. The consecutive sampling method drawn from a single rehabilitation facility and the intrinsic weakness of the GRC for calculating MIC values were limitations of the study. After treatment, 38 participants evaluated with the Mini-BESTest and only 23 participants evaluated with the BBS (out of the 40 participants who had a GRC score of ≥ 3.5) showed a score change equal to or greater than the MIC values. The best minimal important change (MIC) was 4 points for the Mini-BESTest and 7 points for the BBS. In receiver operating characteristic curves, the area under the curve was 0.92 for the Mini-BESTest and 0.91 for the BBS. The standard error of measurement (SEM) was 1.26 and the minimum detectable change at the 95% confidence level (MDC(95)) was 3.5 points for Mini-BESTest, whereas the SEM was 2.18 and the MDC(95) was 6.2 points for the BBS. Test-retest reliability for total scores was significantly higher for the Mini-BESTest (ICC=.96) than for the BBS (ICC=.92), whereas interrater reliability was similar (ICC=.98 versus. After treatment, the maximum score was found in 12 participants (12.9%) with BBS and in 2 participants (2.1%) with Mini-BESTest. Responsiveness and minimal important change were assessed (after 10 sessions of physical therapy) using both distribution-based and anchor-based methods (external criterion: the 15-point Global Rating of Change scale).Īt baseline, neither floor effects nor ceiling effects were found in either the Mini-BESTest or the BBS. Interrater (3 raters) and test-retest (1-3 days) reliability were calculated using intraclass correlation coefficients (ICCs).
Ninety-three participants (mean age=66.2 years, SD=13.2 53 women, 40 men) with balance deficits were recruited. The aim of this study was to compare the psychometric performance of the Mini-BESTest and the Berg Balance Scale (BBS).Ī prospective, single-group, observational design was used in the study. Recently, a new tool for assessing dynamic balance impairments has been presented: the 14-item Mini-BESTest.
