Efficacy of Simeox Airway Clearance Therapy in Children With Cystic Fibrosis

Chest physiotherapy plays a crucial role in treatment of lung disease in cystic fibrosis (CF). New airway clearance techniques (ACTs) adapted to individual needs are still being sought to achieve the best effect of airway clearance. The primary aim of this study is to assess the efficacy of a new ACT (Simeox) on pulmonary function in children with CF. 40 CF patients with stable respiratory function will be randomized 1:1 to Simeox or conventional chest physiotherapy (CCPT) therapy (control group) and treated at home during 1 month. After a short washout period, patients will be treated at home onto the alternative treatment for 1 month (crossover design). Lung function, quality of life, pulmonary exacerbation and safety will be evaluated at 1 month for each therapy period.
