To look at the gastrointestinal motility, we made motility recording with BL-420S and intestine propulsion. Gastrointestinal myoelectric activity That could be a sensitive index of gastrointestinal motility, comprises gradual wave and spike action (quick wave). Gradual wave could influence the mechanical contraction by pacing and directing gastrointestinal contraction[seventeen], as well https://www.directivepublications.org/journal-of-gastroenterology-hepatology-and-endoscopy-research/
