Figure 4.

The effect of liquid consistency on laryngeal vestibule closure reaction time (i.e., the interval between onset of the hyoid burst and the frame of laryngeal vestibule closure). Significantly longer Laryngeal Vestibule Closure Reaction Times (p < .001) were seen with the moderately and extremely thick liquids compared to the thin and slightly thick stimuli. IDDSI = International Dysphagia Diet Standardisation Initiative; LVCRT = Laryngeal Vestibule Closure Reaction Time.
