Measuring Free-Living Physical Activity in COPD Patients

This article reviews the use of accelerometers to measure free-living activity in patients with Chronic Obstructive Pulmonary Disease (COPD). By analyzing existing research, it identifies effective methodologies and outcome measures derived from accelerometer data. The review recommends clinical outcome measures for assessing sedentary behavior and physical activity, offering strong evidence to support accelerometry’s role in clinical trials. It also highlights areas where further research is needed to refine measurement techniques and better understand treatment-related changes in activity levels in COPD patients.
