Is dynamometry able to infer the risk of muscle mass loss in patients with COPD? by Ramos D, Bertolini GN, Leite MR, Carvalho Junior LCS, da Silva Pestana PR, Santos VR, Fortaleza ACS, Rodrigues FMM, Ramos EMC

“…A binary logistic regression model verified whether knee-extension strength (measured by dynamometry) could infer muscle mass loss (from DEXA).Results: Patients with decreased knee-extension strength were 5.93 times more likely to have muscle mass loss, regardless of sex, disease stage, and functional exercise capacity (P=0.045).Conclusion: Knee-extension dynamometry was able to infer muscle mass loss in patients with COPD. …”
