Validity of physical activity monitors during daily life in patients with COPD

  • Published on Nov. 1, 2013

Background: Symptoms during physical activity and physical inactivity are hallmarks of chronic obstructive pulmonary disease (COPD). Our aim was to evaluate the validity and usability of six activity monitors in patients with COPD against the doubly labelled water (DLW) indirect calorimetry method. Methods: 80 COPD patients (mean±SD age 68±6 years and ...


Reliability and validity of the multimedia activity recall in children and adults (MARCA) in people with chronic obstructive pulmonary disease.

  • Published on Nov. 27, 2013

Objective: To determine the reliability and validity of the Multimedia Activity Recall for Children and Adults (MARCA) in people with chronic obstructive pulmonary disease (COPD). Design: People with COPD and their carers completed the Multimedia Activity Recall for Children and Adults (MARCA) for four, 24-hour periods (including test-retest of 2 days) ...

A Longitudinal Study Evaluating the Effect of Exacerbations on Physical Activity in Patients with COPD

  • Published on Sept. 20, 2013

Background Physical inactivity is common in stable COPD and independently predicts poor outcomes. Longitudinal assessments of physical activity in outpatients with COPD, covering periods of stability and exacerbations, have not been evaluated previously. Methods Patients with clinically-stable COPD and a history of 2 or more clinical exacerbations in the preceding 12 months ...


Annual recollection of exacerbations in patients with COPD: Impact on physical activity

  • Presented on Sept. 9, 2013

Rationale The number of exacerbations in the previous year has shown to be the best predictor of new exacerbations. The ability to recall exacerbations may lead to misclassification of patients and may have consequences on patients’ phenotype. Methods 47 patients with COPD (FEV1 65±21%pred) reported on a monthly basis all health ...


Agreement of classification of COPD patients’ physical activity with two activity monitors

  • Presented on Sept. 8, 2013

Rationale It is unclear whether different activity monitors provide similar classification of physical activity (PA) in patients with COPD. Aim To test whether similar PA classification of patients would be obtained when using 2 valid activity monitors. Methods We assessed PA for 4 weeks with Actigraph [(ACT: Steps and vector magnitude units (...
