Inspiratory Muscle Training to Reduce Breathlessness and Improve Activity in Children Aged 8-17 With Obesity and Mild Asthma

What this Trial Is About

Researchers are evaluating inspiratory muscle rehabilitation IMR as an additional treatment to reduce shortness of breath and promote greater physical activity in children aged 8 to 17 years with obesity and asthma. This study is a single-center, randomized, sham-controlled, double-masked trial lasting 8 weeks, focusing on this population who often experience frequent asthma symptoms and limited exercise due to their condition. Participants will use a device called PrO2 that provides resistance during breathing exercises. One group will train at 60% of their maximal inspiratory pressure MIP as the active intervention, while the control group will use the same device but with much lower resistance at 15% MIP. The device includes Bluetooth connectivity and an app for monitoring adherence and giving immediate feedback. The study will assess adherence, participant satisfaction, and inspiratory muscle function over approximately 2 months. During the study, children and their caregivers will be trained to use the device and app. Researchers will monitor breathing muscle strength, respiratory symptoms, and adherence to the treatment. The study will also track how many participants complete the program and gather feedback on their experience. The total participation time is about 8 weeks, with careful monitoring of safety and treatment effects throughout.
