What this study is about

This is a single-center, randomized, SHAM-controlled, parallel assignment, double-masked,8-week interventional study among children aged 8-17 years (not yet 18 years old) of age with obesity and asthma. (n=60), recruited from Duke Health Center Creekstone, 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 and asthma.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Full registry criteria

Inclusion Criteria: * Documented informed consent from legal guardian and assent from participant as appropriate. * Children 8 to 17 years of age with obesity (BMI ≥ 95th percentile for age and sex) and mild asthma. * Participants (or parent/guardian) must have access to the internet and an approved smart device/computer. * Child must have a designated caregiver who expresses a commitment to encourage the participant to complete the study procedures. * Participant and legal guardian must speak and read English. * Child is currently taking prescription medicine for asthma (Any type of albuterol or inhaled steroid) Exclusion Criteria: * Prior intubation for asthma * Current self-reported pregnancy or planning to become pregnant. * Have an FEV1 \< 50% of predicted at screening * History of lung surgery in the past two years, * History of pulmonary embolism in the past two years, * Any history of recurrent spontaneous pneumothorax, or pneumothorax in the past 12 months * Current undiagnosed chest pain, * History of inner ear surgery in the past 12 months, * Undiagnosed syncopal episodes in the past two years, * Progressive neurological or neuromuscular disorders or need for chronic O2 therapy. * Inability to complete baseline measurements satisfactorily according to the research coordinator's or PI's judgment. * Any condition in the opinion of the PI that would not allow safe conduct of study procedures (including IMR, MIP testing or step-test), such as a physical disability, recent musculoskeletal injury or illness, current and ongoing evaluation for undiagnosed cardiopulmonary or neurologic symptoms

Treatments and study arms

Pro2 - 60% of participant's MIP

Device

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 60% of their MIP.

Pro2 - 15% of participant's MIP

Device

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
