Rehabilitation Exercise and Education of Airway Clearance Technique in NTM-PD: A Prospective Cohort Study

* The goal of this observational study is to evaluate the effects of pulmonary rehabilitation and airway clearance education in adults with nontuberculous mycobacterial pulmonary disease (NTM-PD). The main questions it aims to answer are: * Does pulmonary rehabilitation and airway clearance training improve lung function, symptom relief, and quality of life in patients with NTM-PD? * Does this non-pharmacological intervention contribute to better sputum culture conversion rates? * Participants will: * Undergo pulmonary rehabilitation and airway clearance training over an 8-week period (biweekly sessions). * Receive evaluations at baseline, during the intervention, and follow-up assessments at 2 months, 6 months, and final study visit. * Undergo tests including pulmonary function tests (PFT), symptom assessments, bacteriologic evaluations, radiographic imaging (CT/X-ray), and quality of life surveys (EQ-5D-5L, CAT score). * This study aims to provide clinical evidence supporting the role of non-pharmacological treatments in the management of NTM-PD, potentially informing future treatment guidelines and improving patient outcomes.
