Reproducibility of the six-minute walk test and Glittre ADL-test in patients hospitalized for acute and exacerbated chronic lung disease

Abstract

Background:The 6-minute walk test (6MWT) and the Glittre ADL-test (GT) are used to assess functional capacity and exercise tolerance; however, the reproducibility of these tests needs further study in patients with acute lung diseases.Objectives:The aim of this study was to investigate the reproducibility of the 6MWT and GT performed in patients hospitalized for acute and exacerbated chronic lung diseases.Method:48 h after hospitalization, 81 patients (50 males, age: 52±18 years, FEV1: 58±20% of the predicted value) performed two 6MWTs and two GTs in random order on different days.Results:There was no difference between the first and second 6MWT (median 349 m [284-419] and 363 m [288-432], respectively) (ICC: 0.97; P<0.0001). A difference between the first and second tests was found in GT (median 286 s [220-378] and 244 s [197-323] respectively; P<0.001) (ICC: 0.91; P<0.0001).Conclusion:Although both the 6MWT and GT were reproducible, the best results occurred in the second test, demonstrating a learning effect. These results indicate that at least two tests are necessary to obtain reliable assessments.

Safety of early performance of the six-minute walk test following acute myocardial infarction: a cross-sectional study

“…The six-minute walk test (6MWT) is a simple, low-cost, valid and reliable method for evaluating functional capacity. 1 , 2 This test is widely used in the clinical management of patients suffering from chronic lung 3 , 4 and heart 5 , 6 diseases, but its use in acute myocardial infarction (AMI) prior to hospital discharge is still recent and has been little investigated. 7 A possible reason would be that the main guidelines for the 6MWT 2 do not recommend its performance within 30 days of an AMI event.…”

Ventilatory demand and dynamic hyperinflation induced during ADL-based tests in Chronic Obstructive Pulmonary Disease patients

“…The Glittre-ADL test is a multiple-task test that assesses functional status related to ADL in stable 8 - 11 and hospitalized 12 , 13 patients with respiratory disease. It includes activities that require rising from a seated position, activities with lower and upper extremities, as well as walking 8 .…”

Reproducibility of Ventilatory Parameters, Dynamic Hyperinflation, and Performance in the Glittre-ADL Test in COPD Patients

“…Skumlien et al (7) found good reproducibility for the TGlittre in COPD patients and a learning effect of 7% after performing the two tests on different days. José et al (23) performed two tests on the same day and also found good reproducibility (ICC: 0.91) for the TGlittre in hospitalized patients with exacerbation of chronic respiratory diseases, including COPD, and a learning effect of 17%. Tufanin et al (8) found no statistically significant difference between the two TGlittre times, performed on the same day with a 30-minute interval.…”
