Effectiveness of a harmonica-integrated, tele-supervised home-based pulmonary rehabilitation program on lung function and comprehensive health outcomes in patients with chronic obstructive pulmonary d…
Introduction Harmonica playing mimics pursed-lip breathing and strengthens respiratory muscles. Combined with music therapy, it may improve both pulmonary and mental health in chronic obstructive pulmonary disease (COPD) patients, though its effects are not well understood. This protocol outlines a randomized controlled trial (RCT) to evaluate the effectiveness of integrating harmonica playing into pulmonary rehabilitation (PR) programs. Methods …
