Research Article: Effects of Pedometer-Based Step-Feedback on Physical Activity of Severe COPD Patients
Introduction:
Low physical activity (PA) levels are associated with increased healthcare utilization and reduced survival in patients with chronic obstructive pulmonary disease (COPD). – PA levels are associated with disease severity, – with lower PA levels observed in severe COPD patients than in patients with mild to moderate COPD. Thus, improving PA levels is a key COPD treatment goal. , However, improving PA in severe COPD patients is difficult, as they have marked dyspnea and decreased exercise tolerance.
