Breathing Techniques vs. Chest Percussion for Lung Clearance in Children With Cystic Fibrosis

This trial is testing two different ways to help children with cystic fibrosis clear sticky mucus from their lungs. One approach uses a special breathing technique called autogenic drainage, where a therapist teaches your child to breathe in a controlled way to move mucus up and out. The other uses a mechanical percussion device that gently vibrates the chest to loosen secretions. The study will compare how well each method works over six weeks.

Children with cystic fibrosis produce thick, sticky mucus that builds up in their lungs and can lead to breathing problems and infections. While airway clearance therapy is essential, doctors still aren't sure which technique works best for each child, so this trial will help answer that question.
