Table 3.
Frequency distribution of paired-event sequences across bolus volumes, viscosities, and barium concentration. Percentages are based on a ‘YES’ response. [AEstart = onset of arytenoid elevation, Pop = UES opening, BP1 = bolus arriving at the UES, HL = maximum approximation of hyoid and larynx, PESmax = maximum distension of the UES, PAmax = maximum constriction of the pharynx, w/v = weight/volume, ml = milliliters].
