Background Gastric motility disorders, which include both functional and organic etiologies,
are highly prevalent. However, there remains a critical lack of objective biomarkers to guide …

Electrogastrography (EGG) is the noninvasive electrophysiological technique used to record
gastric electrical activity by means of cutaneous electrodes placed on the abdomen. EGG …

Background & Aims Invasive gastric electrical mapping has revealed spatial abnormalities of
the slow wave in subjects with gastroparesis and functional gastrointestinal disorders …

Background Disorders of gastric function are highly prevalent, but diagnosis often remains
symptom‐based and inconclusive. Body surface gastric mapping is an emerging diagnostic …

Despite its simplicity and noninvasiveness, the use of the electrogastrogram (EGG) remains
limited in clinical practice for assessing gastric disorders. Recent studies have characterized …

Over the last two decades, high-resolution (HR) mapping has emerged as a powerful
technique to study normal and abnormal bioelectrical events in the gastrointestinal (GI) tract …

Background and Aims Diabetic gastroenteropathy is associated with poor glycemic control
and morbidity in people with type 1 diabetes (T1D). There is a lack of noninvasive …

Myenteric interstitial cells of Cajal (ICC-MY) generate and actively propagate electrical slow
