The Timed Up and Go test predicts frailty in patients with COPD

This cross-sectional study evaluated the ability of the Timed Up and Go test (an integrated tool for assessing lower extremity muscle strength, gait speed, balance and cognition) to identify frailty in 520 patients with clinically stable COPD, as compared with 150 control subjects without respiratory disease. As part of the study, all participants underwent lung function testing (FEV1, FVC, FEV1/FVC ratio) using the Vitalograph Alpha spirometer.
