The reference equations for the time to complete the Glittre ADL-test were based on age, BMI, and height as independent variables and can be useful for predicting the performance of adult individuals. The predicted values appear to be reliable when applied to COPD patients.
BackgroundThe Glittre-ADL test (TGlittre) is a valid and reliable test for the evaluation of
functional capacity and involves multiple physical activities of daily living
(PADL), which are known to be troublesome to patients with Chronic Obstructive
Pulmonary Disease (COPD). However, it is still unknown if this test is also able
to reflect the functional performance of patients with COPD.ObjectiveTo investigate whether the TGlittre reflects the functional performance of COPD
patients and whether the necessary time to complete the TGlittre and the PADL
varies according to disease severity.MethodThirty-eight patients with COPD (age 65, SD=7 years; forced expiratory volume in
the first second 41.3, SD=15.2% predicted) underwent anthropometric and lung
function assessments and were submitted to the TGlittre and PADL measurement.ResultsTGlittre performance correlated significantly (p<0.05) with PADL variables,
such as time sitting (r=0.50), walking (r=-0.46), number of steps taken (r=–0.53),
walking movement intensity (r=–0.66), walking energy expenditure (r=-0.50), and
total energy expenditure (r=–0.33). TGlittre performance was not significantly
different in patients among the Global Initiative for COPD (GOLD) spirometric
stages, but walking and sitting time were significantly lower and greater,
respectively, in severe and very severe patients compared to those with moderate
disease (p<0.05).ConclusionThe performance on the TGlittre correlates with walking and sitting time and other
real life PADL measurements. The severity of the disease is associated with the
differences in the level of physical activity in daily life more than in
functional capacity.
Objective: To translate The Manchester Respiratory Activities of Daily Living (MRADL) questionnaire into Portuguese and to create a version of the MRADL that is cross-culturally adapted for use in Brazil. Methods: The English-language version of the MRADL was translated into Portuguese by two health care researchers who were fluent in English. A consensus version was obtained by other two researchers and a pulmonologist. That version was back-translated into English by another translator who was a native speaker of English and fluent in Portuguese. The cognitive debriefing process consisted in having 10 COPD patients complete the translated questionnaire in order to test its understandability, clarity, and acceptability in the target population. On the basis of the results, the final Portuguese-language version of the MRADL was produced and approved by the committee and one of the authors of the original questionnaire. Results: The author of the MRADL questioned only a few items in the translated version, and some changes were made to the mobility and personal hygiene domains. Cultural differences regarding the domestic activities domain were found, in particular regarding the item "Do you have the ability to do a full clothes wash and hang them out to dry?", due to socioeconomic and climatic issues. The item "Do you take care of your garden?" was questioned by the participants who lived in apartments, being modified to "Do you take care of your garden or plants in your apartment?" Conclusions: The final Portuguese-language version of the MRADL adapted for use in Brazil was found to be easy to understand and easily applied.
Objective:To investigate the validity of an eight-contact electrode bioelectrical impedance analysis (BIA) system within a household scale for assessing whole body composition in COPD patients. Methods:Seventeen patients with COPD (mean age = 67 ± 8 years; mean FEV1 = 38.6 ± 16.1% of predicted; and mean body mass index = 24.7 ± 5.4 kg/m2) underwent dual-energy X-ray absorptiometry (DEXA) and an eight-contact electrode BIA system for body composition assessment. Results:There was a strong inter-method correlation for fat mass (r = 0.95), fat-free mass (r = 0.93), and lean mass (r = 0.93), but the correlation was moderate for bone mineral content (r = 0.73; p < 0.01 for all). In the agreement analysis, the values between DEXA and the BIA system differed by only 0.15 kg (−6.39 to 6.70 kg), 0.26 kg (−5.96 to 6.49 kg), −0.13 kg (−0.76 to 0.50 kg), and −0.55 kg (−6.71 to 5.61 kg) for fat-free mass, lean mass, bone mineral content, and fat mass, respectively. Conclusions:The eight-contact electrode BIA system showed to be a valid tool in the assessment of whole body composition in our sample of patients with COPD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
