Rationale: Malnutrition is a common problem in patients with Chronic Obstructive Pulmonary Disease (COPD). Whereas estimation of fat-free muscle mass index (FFMi) with bio-electrical impedance is often used, less is known about muscle thickness measured with ultrasound (US) as a parameter for malnutrition. …

Rationale: Currently use of muscle thickness measured with ultrasound is suggested as an indicator for overall muscle mass in nutritional assessment. However, not much is known about how the muscle thickness measured in patients with chronic obstructive pulmonary disease (COPD) compares to the muscle …

The aim of this study, is to assess changes in prevalence and frailty score during pulmonary rehabilitation (PR) in patients with COPD.
