There is an array of tests available to measure gastric motility. Some tests measure end points, such as gastric emptying, that result from several different functions, whereas other tests are more specific and test only a single parameter, such as contractility. This article reviews the tests most commonly available in practice and research to evaluate in vivo the gastric functions of emptying, accommodation, contractility, and myoelectrical activity. The rationale for testing, the relative strengths and weaknesses of each test, and technical details are summarized. We also briefly indicate the applications and validations of the tests for use in experimental animal studies.
有一系列测试可用于测量胃动力。一些测试测量诸如胃排空等由多种不同功能产生的终点指标，而其他测试则更具特异性，仅测试单个参数，如收缩性。本文回顾了实践和研究中最常用的测试，以在体内评估胃的排空、容纳、收缩性和肌电活动等功能。总结了测试的基本原理、每种测试的相对优缺点以及技术细节。我们还简要指出了这些测试在实验动物研究中的应用和验证情况。
