Respiratory Biofeedback Training as an Adjunct Intervention in Pulmonary Rehabilitation for Late-Stage COPD: A Pilot Trial.
Chronic obstructive pulmonary disease (COPD) is associated with persistent dyspnea, reduced functional capacity, and significant cognitive and affective impairments. Pulmonary rehabilitation improves the physical and psychological condition, however residual symptoms often remain, especially in patients with advanced disease.
