Standardizing Swallow Pressure Measurements

This study aims to directly compare and contrast swallowing pressure and impedance measurements obtained from two high-resolution manometry (HRM) systems: the Laborie LMT Pharyngeal System and the Medtronic ManoScan ESO HRM System in healthy adult volunteers. The primary objective is to determine how differences in catheter diameter, sensor configuration, and acquisition platforms influence measurement outcomes. Twenty-five healthy adults will participate in a single, approximately 2-hour visit; the study will be open for one year for data collection and two years for data analysis.
