Figure 1. Study Design.

Figure 1

The figure shows contour plots for: A) Spontaneous swallow, B) Pharyngeal stimulus induced swallows, and C) Oral stimulus induced swallows at the 20 mmHg iso-contour line, the white arrows indicate the presentation of stimulus. D) The pharyngeal region of interest (black box) was identified from the upper border of the proximal pharynx to the upper esophageal sphincter upper border. The pharyngeal region can be distinguished manometrically into proximal and distal regions at the tongue base as shown by the redboxes. PhCI values were calculated if the 20mmHg isocontour threshold was achieved.
