A gastrokinesograph is a medical instrument designed to record the movements of the stomach — its peristaltic contractions, tone, and motility patterns. By capturing how the muscular wall churns and empties, it helps physiologists and gastroenterologists study gastric motility in health and in disorders such as gastroparesis, functional dyspepsia, and post-surgical dysfunction. The device belongs to an era of inventive mechanical recording in digestive physiology, alongside kymographs and balloon manometry. Modern motility investigation has largely moved to less cumbersome tools — antroduodenal manometry, wireless motility capsules, and gastric emptying scintigraphy — but the gastrokinesograph illustrates the long clinical interest in measuring exactly how the stomach moves food along.
