Long Term Effects and of a Pulmonary Rehabilitation Maintenance Program

Long Term Effects and of a Pulmonary Rehabilitation Maintenance Program in Patients With a Chronic Respiratory Disease: Time Course and Determinants

Chronic respiratory diseases are characterized by a progressive and long term deline. Pulmonary rehabilitation (exercise training and therapeutic education) can improve several disease outcomes like dyspnea, exercise tolerance and health-related quality of life. After an inpatient PR program, maintenance program can stabilize the disease outcomes. However, maintenance program are heterogeneous and long term benefits (>36 month) have been observed in only one study, which is not feasible in France. A realistic maintenance program as proposed by the French Air+R network (http://airplusr.com/wordpress/) has only demonstrated benefits after 12 month. In addition, the time course of patients may be heterogeneous, with differens clusters that could be influenced by the clinical, functional and systemic determinants. In particular, the cellular muscle microenvironment could be deleterious for the muscle function in patients, caused by a "spill-over" of inflammatory pulmonary molecules in the systemic milieu.
