 The purpose of this study was to translate and adapt the Berg balance scale, an instrument for functional balance assessment, to Brazilian Portuguese and to determine its reliability. Two translators independently translated the original scale into Brazilian Portuguese and a consensus version was created. A back translation was conducted to resolve any discrepancies. Two translators also performed a back translation. Any items that caused confusion were reformulated and reapplied. The final Brazilian version was then tested on 36 elderly patients over the age of 65. The average age was 72 years old. The intra and inter-observer reliabilities were measured using the intra-class correlation coefficient, ICC, and Pearson's correlation coefficient. The ICC for intra and inter-observer reliability was 0.99, p less than 0.001, and 0.98, p less than 0.001, respectively. The Pearson's correlation coefficient for intra and inter-observer reliability was 0.98, p less than 0.001, and 0.97, p less than 0.001. This article was authored by Estemia Moto, iLombardi Jr., K.O.
