Reliability and validity of the Glittre-ADL test to assess the functional status of patients with interstitial lung disease

Abstract

The study objective was to investigated the reliability and validity of the ADL-Glittre test (TGlittre) to assess the functional status of patients with interstitial lung disease (ILD). Twenty-one individuals with ILD participated (age: 63 ± 11 years; DLCO: 51.0 ± 12.6%predicted), evaluated with body plethysmography, Saint George Respiratory Questionnaire, modified Medical Research Council dyspnea scale, six-minute walk test (6MWT) and monitoring of physical activity of daily living. Two TGlittre were performed, with an interval of 30 minutes between them. The TGlittre demonstrated high test-retest reliability, with an intraclass correlation coefficient of 0.90 (95%CI: 0.75–0.96; p < 0.001). Nineteen patients (90.5%) performed better on the second test (mean difference between TGlittre 1 and 2: −0.57 ± 0.96 minute; p = 0.001), with a learning effect of 11.6%. The time in TGlittre correlated with 6MWT (r = −0.70; p = 0.002) and with the total energy expenditure in physical activity of daily living (r = −0.52; p = 0.02). In %predicted, TGlittre and 6MWT also correlated (r = −0.50; p = 0.04). Correlations were observed between TGlittre and pulmonary function variables (r = −0.47 to −0.57; p = 0.01 to p = 0.04). There was no difference in the physiological response between TGlittre 1 and 2, and between TGlittre and 6MWT (p > 0.05). In conclusion, the TGlittre is reliable and valid for assessing functional status of patients with ILD.

Respiratory Oscillometry in Chronic Obstructive Pulmonary Disease: Association with Functional Capacity as Evaluated by Adl Glittre Test and Hand Grip Strength Test

“…The ADL – Glittre test is an effective, easy-to-apply, valid, and reliable test for assessing functional capacity in COPD 19 and interstitial lung disease. 20 It can be considered more descriptive than the 6-minute walk test (6MWT) to assess functional capacity, as it involves, in addition to walking, activities such as sitting and getting up from a chair, going up and down steps, and arm movements with weight support, tasks considered difficult for these patients. 21 This method is sensitive and specific to distinguish COPD patients with abnormal and normal functional capacity.…”

The interplay of physical and cognitive function in rehabilitation of interstitial lung disease patients: a narrative review

“…Individuals with interstitial lung abnormalities are much less likely to be independent in activities of daily living [adjusted odds ratio 0.70 (0.55 to 0.90)] ( 133 ). The Glittre-ADL, a functional ADL test that evaluates trunk, arm, and leg movements showed worse scores in those with more severe ILD ( 134 ). Advanced IPF can even limit self-care such as showering and simple household chores ( 134 , 135 ).…”

Dyspnea, mood, fatigue, and depression appear to be contributing and/or aggravating factors ( 134 , 135 ).…”

CRD editor’s corner archive: July-September

“…People’s day to day lives are of course much more complex requiring integration of multiple physical capabilities. In this issue of the journal, Alexandre and colleagues 8 test the validity and reliability of a standardised circuit of real-life daily activities such as climbing steps and placing items on a shelf (the ADL-Glittre test) in people with interstitial lung disease. In contrast to the editor’s own housework abilities, participants improved their Glittre performance when it was repeated suggesting a small but significant learning effect.…”
