Summary

This is a single-center, randomized, SHAM-controlled, parallel assignment, double-masked, interventional trial among children aged 8-17 years (not yet 18 years old) of age with obesity (n=30), recruited from the Duke Healthy Lifestyles Clinic to test the effectiveness of inspiratory muscle rehabilitation (IMR) as an acceptable add-on intervention to reduce dyspnea (feeling short-of-breath or breathless) and to promote greater activity in children with obesity

Conditions

  • Pediatric Obesity

Interventions

DEVICE

Pro2 - 75% of participant's MIP

Each participant will be provided a PrO2™ device and trained on its use as well as its accompanying PrO2 Fit™ app. The PrO2™ is a flow-resistive device that provides inspiratory resistance via a fixed 2mm orifice and has Bluetooth connectivity to most IOS/Android devices or Mac/Windows computers. The PrO2™ device and app allows for both 100% adherence monitoring and immediate user biofeedback. Participants will be instructed to inspire forcefully through PrO2™ until the device signals that the user has achieved the target resistance (via audible alarm and visible light signal). The research team will implement biofeedback signals at a specific inspiratory resistance to provide precise and individualized training target. Successful IMR repetitions will require that subjects achieve a pressure target that is 75% of their MIP.

DEVICE

Pro2 - 15% of participant's MIP

Participants in the control intervention will also use the same PrO2™ device but at a reduced peak resistance of 15% MIP. The research team will implement biofeedback signals at a specific inspiratory resistance to provide precise and individualized training target. Successful IMR repetitions will require that subjects achieve a pressure target that is 15% of their MIP for each repetition. Participants will perform 3 sets of 50 inspiratory breaths 3 times per week.
