Three‐Dimensional Analysis of Pharyngeal High‐Resolution Manometry Data

High‐resolution manometry (HRM) represents a critical advance in the quantification of swallow‐related pressure events in the pharynx. Previous analyses of the pressures measured by HRM, though, have been largely two‐dimensional, focusing on a single sensor in a given region. We present a three‐dimensional approach that combines information from adjacent sensors in a region. Two‐ and three‐dimensional methods were compared for their ability to classify data correctly as normal or disordered.
