[Early exercise training after exacerbation in patients with chronic respiratory failure].

Patients who suffered from an exacerbation of a chronic respiratory disorder are often very limited in terms of their exercise capacity because of severe dyspnea and amyotrophy of peripheral muscles. Early implementation of pulmonary rehabilitation may help these patients to avoid the complications of a prolonged bedridden period, and increase more rapidly their mobility. Early rehabilitation has become more frequent, but requires special skills from the care givers (chest therapists). Techniques which enhance muscular performance and motility of patients who are recovering from an exacerbation such as electromoystimulation or mobilisation under non-invasive ventilation, give encouraging results; their impact on length of hospital stay requires further studies.
