TLDR
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.Abstract:
Background Recently, a new tool for assessing dynamic balance impairments has been presented: the 14-item Mini-BESTest.
Objective Aim of this study was to compare the psychometric performance of Mini-BESTest vs. Berg Balance Scale (BBS).
Methods Ninety-three subjects (mean age 66.2; 53 females) with balance deficits were recruited. Interrater (3 raters) and test-retest (1-3 days) reliability were calculated using intraclass correlation coefficients (ICCs). Responsiveness and minimal important change (MIC) were assessed (after 10 sessions of physical therapy) using both distribution-based and anchor-based methods (external criterion: a 15-point Global Rating of Change [GRC] scale).
Results At baseline, neither floor nor ceiling effects were found in either scale. After treatment, the maximum score was found in 12 patients (12.9%) with BBS and in 2 (2.1%) with Mini-BESTest. Test-retest reliability for total scores was significantly higher in Mini-BESTest (ICC=0.96) than in BBS (ICC=0.92), whereas interrater reliability was similar (ICC=0.98 vs. 0.97). The standard error of measurement (SEM) was 1.26 and minimum detectable change at the 95% confidence level (MDC95) 3.5 points for Mini-BESTest, whereas SEM was 2.18 and MDC95 6.2 points for BBS. In receiver operating characteristic (ROC) curves, the area under the curve was 0.92 for Mini-BESTest and 0.91 for BBS. The best Minimal Important Change (MIC) was 4 points for Mini-BESTest and 7 for BBS. After treatment, 38 patients at Mini-BESTest vs. only 23 at BBS (out of the 40 subjects who had a GRC ≥3.5) showed a score change equal or greater than MICs.
Conclusions The two scales behave similarly, but the Mini-BESTest scale seems to have a lesser ceiling effect, slightly higher reliability levels, and greater accuracy in classifying individual patients who show significant improvement in balance function.read more

TL;DR: FOG is associated with more severe decline in postural control, which can be detected by the clinical Mini-BESTest, and this relates to FOG development in Parkinson's disease.

TL;DR: The BESTest was the most sensitive scale for assessing balance recovery in participants with subacute stroke because of its high internal and external responsiveness and lack of floor and ceiling effects.

TL;DR: It is concluded that the findings provide important evidence for pronounced postural instability in individuals with FOG, which can be easily picked up with clinical evaluation tools.

Enhancing the usefulness of the Mini-BESTest for measuring dynamic balance: a Rasch validation study
TL;DR: The reliability indexes confirmed their high values, giving a high degree of confidence in the consistency of both person-ability and item-difficulty estimates, which increases confidence in use of the Mini-BESTest for clinical assessment of dynamic balance in patients undergoing rehabilitation.
