Does the ASPEKT Method require use of a specific videofluoroscopy testing protocol?
No. The ASPEKT Method is an analysis method that is applied at the bolus level. Please see additional information below regarding the methods used during data collection for the ASPEKT Method Reference Values.
Do the ASPEKT Method Reference Values apply to all bolus consistencies?
ASPEKT Method Reference Values are available for thin, slightly thick, mildly thick, moderately thick and extremely thick liquid consistencies, as defined by the International Dysphagia Diet Standardisation Initiative (https://www.iddsi.org).
What kind of barium was used for collecting the ASPEKT Method Reference Values?
The ASPEKT Method Reference Values were collected using Bracco E-Z-Paque powdered barium prepared in a 20% w/v concentration with Nestle Pure Life bottled water. Thickened consistencies were prepared by adding Resource ThickenUp Clear xanthan gum thickener (Nestle Health Science) to the 20% w/v concentration thin liquid E-Z-Paque solution.

What other methodological considerations were controlled during collection of the ASPEKT Method Reference Values data?
- Sip size: The ASPEKT Method Reference Values data were collected using comfortable natural sips of thin, slightly thick and mildly thick barium and comfortable teaspoon-delivered boluses of moderately thick and extremely thick barium.
- Cued vs Non-Cued Swallows: Research participants self-administered these boluses and were instructed to swallow when they felt ready, without waiting for a cue.
- Frame Rate: All swallows were captured using pulsed fluoroscopy at a rate of 30 pulses per second and recorded at a rate of 30 frames per second.
