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 ...
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) ...
Background To assess the relationship between physical activity in second year of life and respiratory symptoms during the pre-school period.
Methods This study was embedded in the Generation R Study, a large prospective birth-cohort study in Rotterdam, the Netherlands. Physical activity was measured in the second year of life by ...
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 ...
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 (...
Reduced physical activity is an important feature of Chronic Obstructive Pulmonary Disease (COPD). Various activity monitors are available but their validity is poorly established. The aim was to evaluate the validity of six monitors in patients with COPD. We hypothesized triaxial monitors to be more valid compared to uniaxial monitors. ...
