Effectiveness of Harmonica Playing in Improving Lung Function Among COPD Patients

Although it has been documented that harmonica playing plays a role in the pulmonary rehabilitation (PR) of patients with chronic obstructive pulmonary disease (COPD), current studies are limited by small sample sizes, uncomprehensive outcome indicators, and short intervention durations. Thus, the investigators aim to compare the harmonica combination group with the basic-PR-care group in terms of improving health outcomes among COPD patients, such as lung function, self-efficacy, quality of life, compliance with training, and emotional distress.
