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 ...


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 (...


Validity of Six Activity Monitors in Chronic Obstructive Pulmonary Disease: A Comparison with Indirect Calorimetry

  • Added on June 20, 2012

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. ...
