Effects of the mendelsohn maneuver on extent of hyoid movement and UES opening post-stroke

Abstract

The Mendelsohn maneuver, voluntary prolongation of laryngeal elevation during the swallow, has been widely used as a compensatory strategy to improve upper esophageal sphincter (UES) opening and bolus flow. Recent research suggests that when used as a rehabilitative exercise, it significantly improves duration of hyoid movement and positively impacts duration of UES opening (DOUESO). The data presented here were derived from that same prospective crossover study of 18 participants with dysphagia post-stroke evaluated with videofluoroscopy after treatment using the Mendelsohn maneuver versus no treatment. Results demonstrate gains in the extent of hyoid movement and UES opening and improvements in coordination of structural movements with each other as well as with bolus flow. © 2013 Springer Science+Business Media New York.
