Timing Is Everything: Diagnosis and Treatment of Laryngeal Vestibule Closure Impairments (PD102480)

Presenter(s): Alicia Kim Vose, PhD, CCC-SLP
Course Description

Impairments in laryngeal vestibule closure (LVC) are a major cause of aspiration during swallowing. Accurately identifying LVC impairment is a priority in dysphagia management as aspiration can occur if LVC is absent or delayed, or duration is reduced. However, this mechanism is often overlooked and underreported in the evaluation of swallowing and in swallowing research. This session discusses methods for incorporating LVC as a primary outcome measure in dysphagia diagnosis and management to increase diagnostic accuracy and optimize dysphagia management.

This course is a recorded session from the 2022 online conference “Controversies and Consensus in Dysphagia Management.”

Learning Outcomes
After completing this session, you will be able to:

  • Comprehensively diagnose laryngeal vestibule closure impairments in individuals with dysphagia
  • Differentially diagnose timing impairments to determine a primary swallowing pathophysiology


  • Overview of laryngeal vestibule closure
  • Pitfall of isolationism
  • Variability in dysphagia diagnosis and treatment selection
  • Impact of modified diets
  • Hard-hitting questions
  • Summary

Presenter Information

Alicia K. Vose, PhD, CCC-SLP, is a Postdoctoral Researcher at the University of Florida and Brooks Rehabilitation and has ~10 years of clinical experience specializing in dysphagia management in the acute care/ICU setting. She completed her PhD in Rehabilitation Science at University of Florida, where she investigated the role of kinematic biofeedback in dysphagia management and physiological mechanisms underlying normal and disordered airway protection. In her postdoctoral training, Dr. Vose maintains a strong commitment to clinical research and focuses on the development of rehabilitation strategies for impairments in swallowing and respiration. Currently, she is investigating the effects of acute intermittent hypoxia and respiratory strength training to enhance breathing and swallowing in individuals with neurologic injury as well as the effects of diaphragm stimulation on respiratory neural drive and function.
