Effects of Expiratory Muscle Training Added to Pulmonary Rehabilitation in Patients With Bronchiectasis

This randomized, single-blind, parallel-group controlled trial aims to investigate the effects of expiratory muscle training added to standard pulmonary rehabilitation on respiratory muscle strength, pulmonary function, cough effectiveness, exercise capacity, dyspnea perception, and quality of life in patients with non-cystic fibrosis bronchiectasis. Eligible patients aged 18-70 years with stable disease will be randomly assigned to either a pulmonary rehabilitation-only group or a pulmonary rehabilitation combined with expiratory muscle training group. Outcomes will be assessed at baseline and after completion of the intervention period.
