Eksperimentel: ACBT + O-PEP First (Group A)
Participants undergo an 8-week standardized home-based pulmonary rehabilitation program combining Active Cycle of Breathing Technique (ACBT) with Oscillatory Positive Expiratory Pressure (O-PEP) therapy.
Training (Week 0): Each participant receives individual face-to-face instruction from a trained research nurse covering: (1) the three ACBT phases - Breathing Control (BC), Thoracic Expansion Exercises (TEE), and Forced Expiration Technique (FET); and (2) correct use of the tube-valve O-PEP device.
Competency is verified by return demonstration.
A home practice manual, self-monitoring diary, and instructional videos (via LINE group) are provided.
Training Protocol (Weeks 1-8): Each session consists of one ACBT cycle (BC → TEE ×3 → FET), followed immediately by 10-15 O-PEP exhalations, then FET, coughing, and expectoration.
Sessions are performed twice daily (≥8 hours apart), approximately 30-60 minutes per session.
Biweekly remote monitoring is conducted by the research team via LINE

Participants undergo an 8-week home-based pulmonary rehabilitation program combining ACBT with O-PEP therapy.
At baseline (Week 0), each participant receives individual face-to-face instruction covering the three ACBT phases - Breathing Control (BC), Thoracic Expansion Exercises (TEE), and Forced Expiration Technique (FET) - and correct use of the tube-valve O-PEP device.
Competency is verified by return demonstration.
A practice manual, self-monitoring diary, and instructional videos are provided.
Each session follows the sequence: BC → TEE ×3 → FET, immediately followed by 10-15 O-PEP exhalations, then FET, coughing, and expectoration.
Sessions are performed twice daily (≥8 hours apart), 30-60 minutes per session, for 8 weeks.
Biweekly remote monitoring is conducted via LINE.
Upon completion, the O-PEP device is retrieved to prevent carryover contamination.
Participants receive standard outpatient medical care only, consisting of routine pulmonology follow-up, prescribed pharmacological management (bronchodilators and/or inhaled corticosteroids as clinically indicated), and standard respiratory health education including disease self-management, smoking cessation, pursed-lip breathing, and diaphragmatic breathing.
No ACBT training, O-PEP device, or individualized airway clearance instruction is provided during this period.

Eksperimentel: Active Comparator: Usual Care First / Delayed Intervention (Group B)
Participants in Group B receive standard outpatient medical care only during Period 1 (Weeks 1-8).
Standard care consists of routine pulmonology outpatient follow-up, prescribed pharmacological management (bronchodilators and/or inhaled corticosteroids as clinically indicated), and standard respiratory health education including disease self-management, smoking cessation, pursed-lip breathing, and diaphragmatic breathing.
No ACBT training, O-PEP device, practice manual, or individualized airway clearance instruction is provided during this period.
Upon crossover at Week 9, participants in Group B begin the active intervention: they receive the same standardized one-on-one ACBT and O-PEP training as Group A (conducted at the Week 8 visit), and subsequently perform the home-based ACBT combined with O-PEP protocol twice daily for 8 weeks (Weeks 9-16), following the identical protocol delivered to Group A during Period 1.

Depression Anxiety Stress Scales-21 (DASS-21), Chinese Version Description: The Chinese version of the Depression Anxiety Stress Scales-21 (DASS-21) is a validated self-report questionnaire consisting of 21 items that assesses three domains: depression, anxiety, and stress (7 items per subscale).
Each item is scored on a 4-point Likert scale ranging from 0 ("Did not apply to me at all") to 3 ("Applied to me very much or most of the time").
Scores for each subscale are summed and multiplied by two to obtain the final score, with higher scores indicating greater severity of depressive symptoms.
In this study, the depression subscale score will be used to evaluate depressive symptoms.
