High Resolution Pharyngeal Manometry (HRPM) Biofeedback

Purpose

The purpose of this study is to quantify the added benefit of visual biofeedback from High Resolution Pharyngeal Manometry (HRPM) for swallowing rehabilitation. Primary aims including assessing changes in swallowing biomechanics (pressure generation, timing) during swallow maneuvers with and without HRPM visual biofeedback. Secondary aim includes participant attitudes related to visual biofeedback and the experience of HRPM.

Swallowing Maneuvers with and without HRPM Biofeedback 		Participants will then undergo a 2-minute period of acclimation with the catheter in place prior to initiating the swallowing protocol and turning on the video biofeedback. Participants will then complete swallowing maneuvers, with 20 seconds between each swallow. The duration of the procedure from catheter placement to removal will be approximately 5-8 minutes.
  • Other: Swallowing Maneuvers
    Swallows will include 5 regular-effort saliva swallows (+/- visual biofeedback), 5 effortful saliva swallows (+/- visual biofeedback), 5 mendelsohn maneuver swallows (+/- visual biofeedback), and 5 masako or tongue hold maneuver swallows (+/- visual biofeedback).
  • Diagnostic Test: High Resolution Pharyngeal Manometry (HRPM)
    A diagnostic tool using a catheter with closely spaced sensors to measure pressures and timing within the pharynx and upper esophageal sphincter (UES) during swallowing
