Abstract

Aim. Balance is important for a successful performance in many tasks of daily living. The Berg Balance Scale (BBS) is perhaps the most widely used scale for balance evaluation in the rehabilitation field. The aims of this study were: a) to produce an Italian version of the BBS (BBS-it) using a validated procedure of cross-cultural translation; b) to analyse the main psychometric characteristics of the BBS-it (internal consistency, reliability, construct and concurrent validity and responsiveness) in patients during a rehabilitation stay. Methods. Eighty-five patients, affected by neurologic and orthopedic diseases, were evaluated using 3 instruments: the BBS-it, the Tinetti Balance subscale (TBS), and the Functional Independence Measure (FIM). The BBS-it was obtained according to a procedure of validated cross-cultural translation. The internal consistency and construct validity of BBS-it were calculated in the total sample of patients, while the concurrent validity and responsiveness of the scale were analysed in the last 40 patients, and the test-retest and inter-rater reliability were studied in 13 patients, randomly chosen. Results. The mean scores of the BBS-it, at admission and discharge, were respectively 26.02 (SD 13.9) and 38.67 (SD 11.4). Cronbach's coefficient of the BBS-it was 0.95, while the correlations between each item and the sum of the remaining items gave generally very high values of r. A 2-way ANOVA did not reveal any significant difference between either the raters or the days. For the inter-rater reliability, the ICC was 0.99. Factor analysis showed that all the items loaded meaningfully onto the first factor (0.70-0.89) except the item 3 "sitting" that had intermediate loading (0.43). The BBS-it demonstrated a significant correlation with the TBS (r=0.96, p
