Abstract:
BACKGROUND:Bioimpedance method can be used to extract physiology and pathology information relative to the gastricmotility states,to investigate the courses of contraction,peristalsis,transmission and emptying of the stomach,to measure andevaluate gastric motility function.However,early studies mainly focused on the emptying of the stomach,and few studies onevaluation of gastric motility by extracting gastric motility information.OBJECTIVE:To understand the gastric motility from electricity-mechanism composite concept and to establish a noninvasive,convenience measurement method of gastric motility impedance.METHODS:Based on the characters of gastric motility impedance signal,a measurement method of impedance gastric motility isintroduced.Some foundation experiments about the gastric emptying measurement,the gastric motility compare between fastingand repast,the gastric motility comparison of healthy volunteers during different periods and some medicine effects on gastricmotility have carried out.The gastric motility measurement of the patients with functional dyspepsia and gastric motility evaluationfor the patients with erosive gastritis had been reported.RESULTS AND CONCLUSION:Using electrical bioimpedance method,according to the electrical property of the stomach tissueor the food in stomach and the change rules of the property,the physiology and pathology information relative to the gastricmotility states can be extracted,the courses of contraction,peristalsis,transmission and emptying of the stomach can beinvestigated and noninvasive measure and evaluation of gastric motility function can be realized.
