<p><strong>Title: What Were We Doing Before? VFSS Reference Values and the Case for Quantitative Measurement with Dr Catriona Steele</strong></p><p><strong> </strong></p><p><strong>Show Notes</strong></p><p>What if you could interpret a video fluoroscopy report the way a doctor reads a blood test, with clear reference ranges, and the ability to say with confidence whether a value is within or outside what&#39;s expected for a healthy adult? That&#39;s exactly what Dr Catriona Steele and her team at the University of Toronto have been working on, and in this episode she walks us through what they&#39;ve found.</p><p><strong> </strong></p><p><strong>In this episode we cover:</strong></p><ul><li>What prompted the development of VFSS reference values.</li><li>How the ASPEKT method differs from ordinal rating tools like MBSImP and what it means to measure swallowing rather than describe it</li><li>What the reference data tells us about residue, and why ASPEKT&#39;s approach to measuring residue is conceptually different from the Bolus Clearance Ratio and DIGEST</li><li>The 2D vs 3D measurement problem: the validity challenges of pixel-based area measures and what Catriona&#39;s team is doing about it</li><li>How many thin fluid swallows you actually need before you can confidently rule out aspiration and whether consecutive sips count</li><li>Why bolus position at swallow onset was dropped from the reference value framework  and what replaced it</li><li>What emerging ASPEKT data is showing across clinical populations including Parkinson&#39;s disease and COPD</li><li>ASPEKT Academy and the clinical workshop coming to Australia</li></ul><p><strong> </strong></p><p><strong>The publication this episode is based on:</strong></p><p>Steele, C.
