Exercise with incorporated expiratory manoeuvres was as effective as breathing techniques for airway clearance in children with cystic fibrosis: a randomised crossover trial.

Question: : Can a session of exercise with incorporated expiratory manoeuvres substitute for a session of breathing techniques for airway clearance in children with cystic fibrosis? Are children with cystic fibrosis as co-operative and satisfied with the exercise regimen as with the breathing techniques?.

Design: Randomised, cross-over trial with concealed allocation and intention-to-treat analysis.

Participants: 34 children with cystic fibrosis in a stable clinical state.
