Impact of External Pharyngeal Exerciser on Pharyngeal Phase of Swallowing
Medical College of Wisconsin
Summary
This study of healthy young and elderly individuals is intended to assess the effects of pharyngeal exerciser on pharyngeal pressure phenomenon during swallowing. Our specific aim is to test if the pharyngeal exerciser increases the workload of muscles involved in pharyngeal phase of swallowing.
Description
1. All the study subjects are required to be without oral food or fluid intake for at least 3 hours prior to the study. 2. The participant's neck's physical dimensions and the device's physical dimensions will be measured and recorded. A physical examination including carotid artery auscultation will be performed. 3. After the application of local lidocaine, the high-resolution manometry (HRM) catheter will be inserted through the more patent nares and positioned such that it covers the entire pharynx from the nasopharynx to the proximal esophagus. In this position, manometry recording of the…
