Chronic Obstructive Pulmonary Disease
Conditions
Brief summary
The goal of observational study is to evaluation of skeletal muscle function in patients with chronic obstructive pulmonary disease before and after lung rehabilitation training using ultrasonic elastography in Chronic Obstructive Pulmonary Disease. The main question it aims to answer are:Evaluation of skeletal muscle function in patients with chronic obstructive pulmonary disease before and after lung rehabilitation training using ultrasonic elastography. Participants will undergo pulmonary rehabilitation.
