Pulmonary Rehabilitation

Harmonica playing is positioned as a complementary adjunct to standard care, not a substitute for medication or pulmonary rehabilitation. The evidence base for harmonica playing is still developing, and clinicians should be cautious about integrating it into routine care until more robust long-term studies are available. Pulmonary rehabilitation dropout rates exceed 60%, driven by monotony and insufficient sustained engagement. Standard pulmonary rehabilitation, which includes respiratory muscle training and exercise therapy, is the cornerstone of COPD management.
