Figure 1. From: High resolution manometry of pharyngeal swallow pressure events associated with head turn and chin tuck.

Spatiotemporal plot of 5 ml swallow in the head turn position. A. Total catheter length within pharynx (rostral boundary is the nasopharynx and caudal boundary is the upper esophageal sphincter (UES) (12 cm in this subject).

Figure 5. From: High resolution manometry of pharyngeal swallow pressure events associated with head turn and chin tuck.

Gradients in velopharynx (A) and tongue base (B) for each swallowing task. Measurements were recorded at the maximum pressure within a region (max), and the pressure at the same time point one (1 cm) and two (2 cm) sensors downstream. Min represents the baseline pressure recorded at the same sensor as the maximum pressure.

Figure 2. From: High resolution manometry of pharyngeal swallow pressure events associated with head turn and chin tuck.

Spatiotemporal plots of neutral (left), head turn (middle), and chin tuck (right) swallows from one subject. Catheter position is on the y-axis, time is on the x-axis, and pressure is indicated by the color scale. A – velopharyngeal pressure; B – tongue base pressure; C – pre-swallow UES pressure peak; D – UES relaxation pressure; E – post-swallow UES pressure peak; (UES opening time is the time duration between D and E); F – increased duration of velopharyngeal pressure above baseline during head turn; G – decreased pre-swallow UES pressure during head turn; H – further subatmospheric UES relaxation pressure during head turn; I – increased duration of velopharyngeal pressure above baseline during chin tuck; J – decreased post-swallow UES pressure peak during chin tuck.
