Effects of Expiratory Muscle Training in Children With Asthma: A Randomised Controlled Trial

he program will include breathing exercises, teaching of relaxation positions, cough training, breathing control strategies, and physical activity recommendations.

Participants perform expiratory muscle training (EMT) using a threshold device at 30% of their maximum expiratory pressure (MEP). The program consists of twice daily sessions, each lasting 20 minutes, at least 5 days per week, for 8 weeks. Resistance will be increased by 10% each week, adjusted according to tolerance and the presence of any complaints for experimental group.
