Objective: The aim of this research was to determine reference values, as well as the sensitivity and specificity for the Berg Balance Scale and gait speed in institutionalized elderly. Method: The Berg Balance Scale (BBS) and the 10-meter test (gait speed) were applied for postural balance evaluation. Receiver Operating Characteristic (ROC curve) was used to identify the best cut-off points for each test and the areas under the curve and the 95% CIs were determined, as well as the analysis of Sensitivity and Specificity values. Results: A value ≤ 49 (sensitivity: 72%, specificity: 74%) was found for BBS and a value ≤ 0.77 m/s (sensitivity: 72%, specificity: 70%) was found for gait speed. Conclusion: The results indicated a value below 49 points for BBS and less than 0,77 m/s for gait speed.
