Inspiratory Muscle Training in Children and Adolescents With Idiopathic Scoliosis Undergoing Schroth Therapy.

"Participants will perform inspiratory muscle training using a respiratory muscle trainer. The initial training load will be set at 30% of PImax.~The intervention will last for 8 weeks and will be carried out 5 days per week, twice daily, in 3 sets of 10 repetitions.~The training load will be increased in the 2nd, 4th, and 6th week of the program, each time by an additional 10% relative to the initial PImax."

"The training intervention in the Sham Group will differ from the experimental group only in terms of training load.~This load will remain constant at 15% PImax, which does not cause any changes in the functioning of the inspiratory muscles.~All other training parameters will be identical to those in the IMT group."
