Interobserver agreement on normal swallowing physiology as viewed by videoendoscopy.
This study examines the agreement of 2 observers in identifying selected normal oropharyngeal swallow events in the 1- and 5-ml swallows of 3 normal young adult males as identified by videoendoscopy at each of two endoscopic positions: (1) with the tip of the endoscope just at or below the tip of the uvula (high position), and (2) with the tip of the endoscope just below the tip of the epiglottis (low position), and thereby defines the needed focus for observer training in endoscopic assessment of swallowing. Overall, the more and less experienced examiners agreed on seeing or not seeing the onsets and terminations of the 12 events 83% of the time. Scope position affected observer agreement on several events while bolus volume did not.
