To observe the gastrointestinal motility, we created motility recording with BL-420S and intestine propulsion. Gastrointestinal myoelectric activity that is a sensitive index of gastrointestinal motility, comprises gradual wave and spike activity (quick wave). Sluggish wave could impact the mechanical contraction by pacing and directing gastrointestinal contraction[seventeen], as well... https://www.directivepublications.org/journal-of-gastroenterology-hepatology-and-endoscopy-research/
