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