Abstract

A system of magnetic field goniometry was developed for measuring the frequency of stomach contractions. This technique uses a handheld, electronic compass to measure the angular change in direction of a magnetic field generated by a small, ingested magnet. Measurements of gastric mechanical activity made by goniometry were validated with simultaneous measurements using manometry and electrogastrography. The agreement between these different modalities was excellent. In this pilot study, magnetic field goniometry provided an easy, minimally invasive, and accurate method to measure the frequency of gastric contractions.
