To observe the gastrointestinal motility, we manufactured motility recording with BL-420S and intestine propulsion. Gastrointestinal myoelectric action that is a delicate index of gastrointestinal motility, comprises sluggish wave and spike action (rapidly wave). Gradual wave could impact the mechanical contraction by pacing and directing gastrointestinal contraction[17], and also the... https://www.directivepublications.org/journal-of-gastroenterology-hepatology-and-endoscopy-research/
