Autogenic drainage (AD)
Resistive inspiratory manoeuvre (RIM)
Resistive inspiratory manoeuvre+autogenic drainage
Patients will perform the autogenic drainage technique following the Chevallier and Agostini recommendations.
Patients will perform the repetitive inspiratory manoeuvers by breathing through a fixed resistance (Power Breathe device, model KH1) . Each session will comprise to cycles of 5 inspiratory breaths (60% of maximal inspiratory pressure). Patients will be stay in both lateral decubitus position (15 min per side).
First, patients will perform the resistive inspiratory manoeuvre during 10 minutes (5 min per side). Right after, patients will perform the autogenic drainage during 20 minutes.The instructions will be similar to described previously.
