Summary

The aim of this randomized controlled trial is to evaluate the effectiveness of gamified mobile health (mHealth) applications for airway clearance therapy in children and adolescents with cystic fibrosis. Primary outcomes include Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV₁), adherence to therapy, health-related quality of life (HRQoL), and satisfaction with the intervention. The intervention will consist of 20-minute sessions, performed twice daily over a 24-week period. At least a total of 36 participants aged 8 to 18 years with cystic fibrosis will be randomly assigned to three equally sized groups: the experimental group (gamified mHealth apps: Voice Volume Catcher, Scream Go Hero, and Chicken Scream), the control group (conventional airway clearance techniques: Autogenic Drainage, Active Cycle of Breathing Techniques, and Positive Expiratory Pressure therapy), and the mixed group (10 minutes of gamified mHealth apps combined with 10 minutes of conventional techniques). This study seeks to provide evidence on the feasibility and clinical benefits of integrating gamification into airway clearance therapy to improve respiratory outcomes and patient engagement in pediatric cystic fibrosis care.

Interventions

Type	Name	Description
OTHER	Gamified mobile health applications	* Voice Volume Catcher: A game where players control a character's movement by modulating their voice volume. Louder or softer sounds move a basket to collect different types of fruits, encouraging continuous vocal engagement and fine control of breath intensity. * Scream Go Hero: A voice-controlled platform game where players produce short or long vocalizations to make the hero character jump or move across obstacles. The game demands breath control and supports prolonged exhalations for larger jumps with an open glottis, which is beneficial for airway clearance. * Chicken Scream: A voice-activated game where players guide a chicken character by varying their vocal intensity to make it walk, jump, and avoid enemies. Participants must dynamically adjust their breath pressure and vocal intensity while maintaining open-glottis breathing, promoting agility in respiratory control.
OTHER	Conventional Airway Clearance Therapy	* Autogenic Drainage: A technique where participants perform a series of controlled breathing cycles-deep inhalations followed by forceful exhalations-to mobilize mucus from the lower airways to the upper airways. The technique encourages breath control and helps clear secretions without the need for coughing, promoting efficient airway clearance. * Active Cycle of Breathing Techniques (ACBT): In this technique, participants alternate between relaxed breathing, deep breaths, and huffing to mobilize and expel mucus from the lungs. It focuses on breathing control to loosen and expel secretions effectively while maintaining a steady airflow throughout the process. * Positive Expiratory Pressure (PEP) Therapy: This technique involves exhaling against a resistance through a device, which helps to open the airways and prevent their collapse. The resistance promotes prolonged exhalations, facilitating the movement of mucus from the small airways to the larger airways for easier clearance.
