To watch the gastrointestinal motility, we designed motility recording with BL-420S and intestine propulsion. Gastrointestinal myoelectric exercise that is a delicate index of gastrointestinal motility, comprises slow wave and spike exercise (rapid wave). Gradual wave could impact the mechanical contraction by pacing and directing gastrointestinal contraction[seventeen], and the spike... https://www.directivepublications.org/journal-of-gastroenterology-hepatology-and-endoscopy-research/
