Adults with asthma may have limitations in their activities of daily living (ADL) and among the most used tests to assess ADL, performance-based instruments such as the Glittre-Activities of Daily Living (Glittre-ADL) test are available. However, metric properties of this instrument have not yet been investigated in this population. To verify the construct validity and reliability of the Glittre-ADL test in adults with asthma. Fifty-eight adults with asthma had their ADL objectively assessed by Glittre-ADL test, which was performed twice by the same rater. Lung function (spirometry), functional exercise capacity (6-minute walk test, 6MWT), and quality of life (St George's Respiratory Questionnaire, SGRQ) were also assessed. Participants were 31% men; 43 ± 14 years; FEV1 74 ± 18% predicted. Performance in the Glittre-ADL test correlated with the 6MWT (r = −0.61; P <.0001) and had excellent intraclass correlation coefficient ICC3,1 = 0.95. Standard error of measurement was 23%, and the minimal detectable change was 29 seconds. Furthermore, the learning effect was 11 seconds (5.03%). The Glittre-ADL test is valid and reliable for assessing ADL in adults with asthma. However, considerable learning effect was observed and therefore the best of two measures can avoid underestimation. [ABSTRACT FROM AUTHOR]

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]
