Changes in Clinical Parameters During Low-Frequency Outpatient Pulmonary Rehabilitation for Male Patients With Chronic Obstructive Pulmonary Disease

While low-frequency PR over two years showed limited efficacy in maintaining physical activity levels and ADL, it contributed to symptom stabilization and a reduction in acute exacerbations. These findings suggest that monthly PR sessions are insufficient to achieve significant improvements in cognitive function or physical activity. High-frequency interventions may be required to optimize outcomes. Additionally, the challenges in maintaining long-term adherence to PR highlight the potential benefits of integrating home-based or telerehabilitation approaches into comprehensive intervention strategies.
