Resumo

Cavalheri V, Hernandes NA, Camillo CA, Probst VS, Ramos D, Pitta F. Estimation of maximal work rate based on the 6-minute walk test and fat-free mass in chronic obstructive pulmonary disease. Arch Phys Med Rehabil 2010; 91:1626-8. Objective: To propose a predictive equation of the maximal work rate (Wmax) in patients with chronic obstructive pulmonary disease (COPD) based on the product of 6-minute walking test (6MWT) and fat-free mass (FFM) and to compare it with a previously proposed equation based on the product of 6MWT and body weight (BW). Design: Descriptive (cross-sectional) study. Setting: University-based rehabilitation center. Participants: Patients with COPD (N=53; 30 men; forced expiratory volume in I second, 45%+/- 15% predicted). Interventions: Not applicable. Main Outcome Measures: Three Wmax were produced: Wmax\_real (obtained from the maximal cycle ergometry test), Wmax\_BW (estimated from the product of 6MWT and BW), previously proposed by Hill et al. (Arch Phys Med Rehabil 2008; 89(9):1782-7); and Wmax\_FFM (estimated from the product of 6MWT and FFM). Results: The equation derived from a regression model to estimate Wmax\_FFM was as follows: -27.9717+ 3.7792{*}(6MWT{*}FFM). Wmax\_real correlated better with Wmax\_FFM (r=.64) than with Wmax\_BW (r=.54). There was no difference between Wmax\_FFM (median {[}interquartile range], 41 {[}29-50] W) and Wmax\_real (40 {[}20-50] W, P=.88), whereas Wmax\_BW (60 {[}52-69] W) significantly overestimated Wmax\_real (P<.0001). Conclusions: In patients with COPD, Wmax is better estimated by an equation including the product of 6MWT and FFM than by a previously proposed equation including the product of 6MWT and body weight.
