Breathing battle: pilates vs. pursed lips for COPD relief

This study compares two breathing techniques—Pilates breathing and pursed lip breathing—to see which one better improves chest expansion and peak airflow in people with mild chronic obstructive pulmonary disease (COPD). Researchers will enroll 46 adults aged 40 to 64 with mild COPD. Participants will practice one of the two techniques alongside their usual medications, and the study will measure changes in chest expansion, peak expiratory flow rate, and shortness of breath.
