Illustration of measurements of pharyngeal manometry reported in table 3. Amp = amplitude, maximum contraction pressure (mmHg); coord = coordination measured as the time between the start of pressure increase at Ph Low (Ph Low-start) and the start of UES relaxation (UES relaxation-start); Dur = contraction duration (ms); Ph Low = lower pharyngeal manometry transducer; Ph Up = upper pharyngeal manometry transducer; TB = tongue base; slope = contraction rate (mmHg/s); UES = upper esophageal sphincter.
