The Effect of Inspiratory Muscle Training on Functional Gain in Cerebral Palsy: A Randomised Controlled Trial

Participants in this group will undergo inspiratory muscle training (IMT). The resistance to be applied at the start of IMT has been set at 30% of the maximum inspiratory pressure (MIP) value. The MIP value will be remeasured every week, and the training load will be updated according to 30% of the new value obtained. IMT will be carried out twice a week with a physiotherapist and on the remaining days as a home programme, for a total of eight weeks, five days a week, 15 minutes a day. Participants in the experimental group will receive traditional physical therapy treatments for cerebral palsy in the same manner as the control group. In this context, traditional physical therapy methods based on neurodevelopmental principles will be applied and designed according to the individual's needs.

Participants in the control group will undergo a neurodevelopmental-based traditional physiotherapy programme for 8 weeks, with two 40-minute sessions per week under the supervision of a physiotherapist; on other days, they will be asked to continue the exercises taught to their families at home.
