Texture Modification and Its Impact on Swallowing Function (PD102478)

Presenter(s): Catriona M Steele, PhD, CCC-SLP
Course Description

SLPs who work with people with dysphagia face the challenge of identifying food textures and liquid consistencies that will optimize swallowing safety and efficiency while minimizing negative consequences on quality of life and nutrition. This session features case-based opportunities to practice the skills involved in determining when and how texture modification can be used to improve swallowing outcomes.

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:

  • Compare videofluoroscopic measures of swallowing physiology of different liquid consistencies to reference values to determine which values are typical or atypical
  • Explain how thickened liquids influence penetration-aspiration and related physiological parameters
  • Teach a patient or caregiver how to determine the consistency of a food or liquid using standardized texture testing methods


  • Brief history of texture modification
  • What does the evidence say? How does consistency impact swallowing function and physiology?
  • The great debate: Compensation, rehabilitation, or clinician comfort?
  • Deciphering "normal" from "abnormal" swallowing, and how to use reference values
  • Applying this knowledge to reveal mechanisms of impairment
  • Resources and tools for patients, caregivers, and clinicians
  • Take-home messages
