Using Body Surface Gastric Mapping Device to Study Stomach Activity and Gastrointestinal Symptoms in Children and Young Adults

What this Trial Is About

Researchers are investigating gastric myoelectric activity in children and young adults aged 8 to 25 years who have gastrointestinal GI symptoms. The study aims to identify patterns or signals from a non-invasive body surface gastric mapping BSGM device that are linked to GI symptoms. This observational study compares stomach activity recordings between healthy children and those with GI disorders to establish normal and abnormal GI activity patterns. Participants will wear the BSGM device to record stomach activity for up to 4 hours, including 30 minutes before and 4 hours after a meal. This study includes children and young adults with functional GI and motility disorders and healthy controls. Researchers will also compare BSGM results with other diagnostic tests and evaluate changes in BSGM patterns following therapeutic interventions such as heart rate variability biofeedback, electrical nerve stimulation, Botox injections, and gastric electrical stimulation. During the study, participants will log symptoms in real time while wearing the BSGM device. Researchers will assess multiple outcomes, including pediatric reference ranges, abnormal BSGM patterns, symptom severity, functional disability, and quality of life measures. The study also compares BSGM data with gastric scintigraphy and antroduodenal manometry. Participants will be monitored at baseline and after some treatments, with assessments ongoing up to two weeks after interventions. The total study duration varies by participant involvement.
