Respiratory Rehabilitation and Sleep Quality in COPD Patients

Summary

COPD affects 5 to 8% of the population in France. The disease consists of inflammation of the large and small airways causing permanent obstruction of the airways and symptoms such as dyspnea, cough and sputum that worsens over time. Among all COPD patients, 40% complain of sleep disorders. Polysomnography data showed a prolongation of sleep onset latency and a decrease in deep sleep, correlated with the severity of daytime hypoxemia. Conversely, poor sleep quality leads to an increase in dyspnea, altered quality of life and increased occurrence of COPD exacerbations. Respiratory rehabilitation has demonstrated significant benefits on exercise capacity, dyspnea, COPD exacerbations and quality of life. To the investigators' knowledge, a few studies have investigated the relationship between physical activity and sleep quality using polysomnography in this population. Thus, the aim of the study is to evaluate the benefits of respiratory rehabilitation on sleep architecture in patients with COPD. Investigators' hypothesis is that a respiratory rehabilitation program would improve the quality of sleep measured by polysomnography. Therefore, patient with COPD and no exacerbation in the previous year will be randomly assigned to the interventional group who perform the rehabilitation program or to the control group who will not perform the program. The primary endpoint is the sleep quality estimated by total sleep time as measured by the mean of 2 independent polysomnography readings, at baseline and after the RR program in the interventional group and after 2 months of usual care in the control group.
