Influence of Expiration Lente Prolongée on Gastro-oesophageal Reflux

l'Expiration Lente Prolongée (ELPr) is a passive technique to enhance the expiration used in infants, obtained by a slow and increasing manual thoraco-abdominal pression applied at the end of a spontaneous expiration till the residual volume. The aim is to obtain a bigger expired volume compared to a normal expiration and drain the mucus out of the airways (Postiaux 2003). This technique has been invented by Guy Postiaux and is used in the Chest Physiotherapy (CPT).
