Pulmonary rehabilitation--physical modalities

This review assesses the role of controlled breathing techniques (breathing training) and chest physical therapy (PT) in the management and rehabilitation of patients with chronic obstructive pulmonary disease (COPD). The review focuses on pursed lip breathing, the head-down and bending forward postures, slow deep breathing, and diaphragmatic breathing exercises as methods of breathing training, and on postural drainage, chest percussion and vibration, and controlled cough as techniques of chest PT. These modalities may be beneficial in selected patients with COPD.
