RESUMO
@#Objective To compare the differentiating effect of Berg Balance Scale (BBS), Mini-Balance Evaluation Systems Test (Mini-BESTest) and Brief-BESTest on the risk of falls in chronic obstructive pulmonary disease (COPD) patients. Methods From September, 2016 to March, 2017, 22 COPD patients with history of falls and other age-matched 66 COPD patients without history of falls were assessed with BBS, Mini-BESTest and Brief-BESTest. The data were compared with paired Logistic regression, Log-likelihood estimate, and the skewness coefficient were calculated. Results BBS, Mini-BESTest and Brief-BESTest all were valuable for differentiating the risk of falls in COPD patients. Log-likelihood estimate value was the least in Brif-BESTest (5.372), followed with Mini-BESTest (12.918) and BBS (17.644). There was not a ceiling effect in Brief-BESTest and Mini-BESTest, but there was in BBS. Conclusion All the BBS, Mini-BESTest and Brief-BESTest can predict the risk of falls in patients with COPD, and Brief-BESTest is the most predictive. There is a ceiling effect in BBS for COPD patients, but not in Brief-BESTest and Mini-BESTest.
