Overview
This study will investigate the effects of a chest physiotherapy manual technique (autogenic drainage) on ventilation inhomogeneity in patients with cystic fibrosis. Lung clearance index (LCI) is the primary outcome
Description
This is a cross-over intervention assessing the effect of autogenic drainage on ventilation inhomogeneity in patients with cystic fibrosis.
Electrical impedance tomography and multiple breath nitrogen washout will be performed before, immediatly after and 2h post intervention. Each participant will receive either aerosoltherapy alone or in combination with chest physiotherapy on 2 consecutive days.
