This study evaluates the effect of a structured three-month pulmonary rehabilitation (PR) program, delivered both in-hospital and at home, on exercise capacity, respiratory symptoms, and functional status in stable COPD patients.

Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of mortality and morbidity worldwide, significantly reducing patients' physical activity and quality of life. This study investigates a tailored pulmonary rehabilitation program combining hospital-based and home-based components over 12 weeks. The hospital component includes patient education, nutritional support, structured exercise training for both upper and lower limbs, and smoking cessation strategies. The home program emphasizes continuity with daily walking, strength exercises, and lifestyle modifications. The program aims to improve exercise capacity, dyspnea scores, and quality of life. Assessments include the six-minute walk test (6MWT), CAT score, mMRC dyspnea scale, spirometry, arterial blood gas analysis, and the St George's Respiratory Questionnaire. Measurements are collected at baseline and after program completion to assess improvements.
