Pharyngo-Esophageal Modulatory Swallow Responses to Bolus Volume and Viscosity Across Time.

ABSTRACT:

Objectives/hypothesis

Modulation of the pharyngeal swallow to bolus volume and viscosity is important for safe swallowing and is commonly studied using high-resolution pharyngeal manometry (HRPM). Use of unidirectional pressure sensor technology may, however, introduce variability in swallow measures and a fixed bolus administration protocol may induce time and order effects. We aimed to overcome these limitations and to investigate the effect of time by repeating randomized measurements using circumferential pressure sensor technology.

Study design

Sub-set analysis of data from the placebo arm of a randomized, repeated measures trial.

Methods

HRPM with impedance was recorded using a solid-state catheter with 36 circumferential pressure sensors and 18 impedance segmen
