Minimal Important Difference for the Glittre-ADL Test and London Chest Activity of Daily Living Scale

Background: The ability to perform activities of daily living (ADL) in patients with chronic obstructive pulmonary disease is often impaired. Glittre-ADL Test has been used to assess limitations in ADL, and it seems to be responsive to intervention. However, the minimal detectable change for Glittre-ADL Test remains unknown. Design: Non-controlled before and after study. Setting: The study will be conducted in an outpatient pulmonary rehabilitation program in Florianopolis, Brazil. Subjects: Patients with COPD (GOLD II-IV). Interventions: Pulmonary rehabilitation program based on physical training, conducted over 24 sessions supervised, three times a week, including aerobic training in treadmill and localized training for upper limbs and lower limbs. Main measures: Glittre ADL-Test performance, six-minute walk test performance, London Chest Activity of Daily Living score, Modified Medical Research Council score, COPD Assessment Test score, Saint George Respiratory Questionnaire score before and after the pulmonary rehabilitation program.
