Effectiveness of Harmonica Playing in Improving Lung Function Among COPD Patients

The intervention will last for a total of six months. During this period, patients are expected to play the harmonica daily for 30 minutes, five days a week. Additionally, patients will receive basic pulmonary rehabilitation (PR) care, which includes self-management education, exercise training, and breathing training, as well as routine follow-up. All training sessions are home-based and will take place five days per week for the duration of six months.
