Londrina ADL Protocol (LAP) Performance of Patients with Chronic Obstructive Pulmonary Disease in Different Gravity Classes.

Studies on the association between functionality and severity of chronic obstructive pulmonary disease (COPD) are conflicting. The GOLD ABCD system, as it includes variables by influence such as activities of daily living (ADLs), would be discriminative to verify the magnitude of the disease influence on functionality. The aims of this study are to compare the performance in the ADLs of patients with COPD classified at different levels of severity according to the GOLD ABCD system, as well as to verify the association among these variables. Participants performed the Londrina ADL Protocol (LAP) to assess ADLs, as well as: lung function, functional exercise capacity and clinical history. LAP time was compared among the GOLD-A (n = 13), GOLD-B (n = 18) and GOLD-C + D (n = 14) groups by the Kruskal-Wallis test. X2 test and V Cramer were used for analysis. The level of statistical significance adopted was P<0.05. For this study, 45 COPD patients completed the assessments (22 men; 65±8 years; FEV1: 51±15% predicted, 6MWT: 520±25m). Overall LAP runtime was 32[275-354] seconds (96[86-106]% predicted). When grouped together, the LAP time was 330[276-348]sec, 318[272-365]sec and 318[282-386]sec in the GOLD-A, B and C+D groups, respectively (P=0.78). There was no association between performance on the LAP and classification by the GOLD ABCD (P=0.24 and VCramer=0.27). It is possible to conclude that the performance in the ADLs of patients with COPD did not differ among the different levels of the GOLD ABCD. Other factors can interfere with performance in the LAP, due to the need for further studies. [ABSTRACT FROM AUTHOR]
