Impact of Bronchial Drainage Technique by the Medical Device Simeox® on Respiratory Function and Symptoms in Adult Patients With Cystic Fibrosis

Impact of Bronchial Drainage by the Medical Device Simeox® on Function and Respiratory Symptoms Compared to Manual Autogenous Drainage Physiotherapy in Adult Cystic Fibrosis Patients

The main objective of the study is to evaluate the short-term effects of the airway clearance technique by the medical device Simeox (Physio Assist, France) versus Autogenic Drainage, on the pulmonary function of adult patients with stable cystic fibrosis. To analyse these effects, the investigators used forced oscillation technique measured by TremoFlo™ C-100 Airwave Oscillometry System™ (THORASYS Thoracic Medical Systems Inc. Montreal, Quebec, Canada) with an evaluation of the perceived clinical benefits.
