Table 4.

Frequency (percentage) adherence to the expected sequence of pharyngeal phase events by consistency.

Consistency	BPM < HYB	HYB < UESO	UESO < UESMax	UESMax < MPC	MPC < UESC	Overall sequence
Thin	87.9	94.5	100.0	100.0	93.6	77.1
Slightly thick	87.6	95.6	100.0	100.0	97.4	80.5
Mildly thick	89.4	97.4	100.0	100.0	98.2	84.8
Moderately thick	82.6	100.0	100.0	100.0	99.1	81.7
Extremely thick	84.1	99.1	100.0	100.0	100.0	83.2
Total	86.3	97.3	100.0	100.0	97.7	81.5

Note. BPM = bolus passing mandible; HYB = hyoid burst onset; UESO = upper esophageal sphincter opening; UESMax = maximum diameter of upper esophageal sphincter distension; MPC = maximum pharyngeal constriction; UESC = upper esophageal sphincter closing.
