Summary

Conventional pulmonary rehabilitation programs improve exercise tolerance, peripheral muscle strength, and health related quality of live but not pulmonary function in patients with chronic obstructive pulmonary disease (COPD). The role of breathing retraining techniques in the rehabilitation of patients with COPD remains unclear. The hypothesis to be tested in this study is that pulmonary function, cardio-pulmonary exercise capacity, health related quality of life and cardiac autonomic modulation of patients with COPD who undergo pulmonary rehabilitation plus breathing retraining will be better than that of patients undergoing a conventional pulmonary rehabilitation.

Conditions

Interventions

OTHER

respiratory biofeedback

In order to train effortless diaphragmatic breathing techniques the biofeedback loop starts at the sensor that measures the patient's breathing rhythm at both umbilical and abdominal level. The sensor is connected to an amplifier that converts the electrical impulses into acoustical and visual outputs. Patients were encouraged to regulate their breathing patterns at a 10-20% slower respiration rate resulting in increased tidal volumes. Furthermore, the patients were encouraged to reduce dynamic hyperinflation by completing the expiration prior to the initiation of the next breath while using pursed-lips breathing. Patients were trained to breath as comfortable as possible with predominant abdominal expansion during the inhalation and smooth abdominal contraction during exhalation.
