This study will investigate the effects of on technique of chest physiotherapy on pulmonary function. Effects of pulmonary function will be measured by the spirometry, body plethysmography and by the multiple breath nitrogen washout technique.
This is a before-after intervention study. Spirometry, body plethysmography and then multiple breath nitrogen washout will be measured before the application of chest physiotherapy. The chest physiotherapy technique used will be autogenic drainage during 30 minutes. A resting period of 5 minutes will be given to the participant before the following tests. Spirometry, body plethysmography and then multiple breath nitrogen washout will be measured again, in the same order, after the application of chest physiotherapy.

Change of Lung Clearance Index (LCI)
LCI will me measured before and after the chest physiotherapy session
Time frame: up to 80 minutes
Change of Spirometry
Forced expired volume in one second (FEV1) and Forced expired flow at 25-75% of the forced vital capacity (FEF25-75) will be measured before and after the chest physiotherapy session
Time frame: up to 40 minutes
Sputum weight
Sputum will be collected during the 30 minutes of chest physiotherapy session and 5 minutes immediately after. Sputum weight will be measured and correlated with change of LCI and spirometry values
Time frame: 35 minutes
