Abstract

Impact of COPD is the presence of chest wall disorders and thoracic mobility disorders, it is necessary for physiotherapists to provide breathing exercises to patients with COPD. Respiratory training methods used in this study are maximal inspiratory exercise (MIE) and pursed-lip breathing (PLB) for chest wall expansion in patients with chronic obstructive pulmonary disease (COPD). This study aims to identify the difference between MIE and PLB in 30 patients with COPD. From the current observations performed in 12 weeks with 3 times per week dosing, it was found that each MIE and PLB group an increased chest wall expansion after treatment. The main results showed that the values of MIE (3.1 ± 0.57) and PLB (2.1 ± 0.72) differed significantly after treatment. The value of MIE was higher than PLB's. This value is value of inspiration and expiration during the breathing process taken before and after treatment. This proves that MIE is better for increasing chest wall expansion in patients with COPD.
