Measurement scales that require a human interface are characterized by some level of subjectivity. The necessary precision of the scale depends, in part, on the clinical purpose or research question that drives the videofluoroscopic study (VFS). This session introduces technological, procedural, and analysis factors that optimize objectivity and reproducibility of clinically valid videofluoroscopic measurements made from modified barium swallow (MBS) studies. The speaker addresses the importance and preferred practices for learning, training, and measurement skill calibration and demonstrates positive and negative influences of clinical bias on VFSS measurement and interpretation. The session presents the value of novel machine vision methods integrated into MBS workflow to aid measurement objectivity and reliability.

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:

  • Describe the relationship between precision and purpose of VFS measures
  • Implement measurement skill calibration between SLP colleagues in clinical practices
  • Explain the role of machine vision methods for computer-assisted swallowing measurements integrated into the MBS workflow
