The aim of this study was to examine the responsiveness and the minimal important change (MIC) of the Mini-BESTest after four weeks of the balance exercises.Methods: A prospective single group pretest-posttest design was applied, and forty-eight type 2 diabetic patients with peripheral neuropathy were participated (mean age of 59.04 ± 7.533 years; 3 males and 45 females). All participants were given an intervention program including foot care and balance exercises (50-minute sessions, three times a week for four weeks). The responsiveness of the Mini-BESTest was determined using two approaches: 1) the distribution-based method evaluating the change scores (pre- and post-intervention), the effect size (ES), the standard response mean (SRM), the standard error of measurement (SEM) and the minimum detectable change (MDC95) and 2) the anchor-based method evaluating the MIC using the Global Rating of Change scale (GRC) as an external criterion.Results: After the balance exercises treatment, the Mini-BESTest scores significantly improved (p 3 for the discrimination of the Mini-BESTest between improvement and no improvement after exercises.Conclusion: The Mini-BESTest can be demonstrated as high responsiveness according to the determination of the distribution-based and the anchor-based methods. The MIC of the Mini-BESTest was taken as ≥ 5 points and could be used as an outcome measure for the discriminated evaluation of type 2 diabetic patients with peripheral neuropathy.Graphical Abstract: Keywords: balance, diabetic peripheral neuropathy, Mini-BESTest
