High-resolution manometry test swallows and maneuvers. (A) Supine 5 mL liquid; (B) upright 5 mL liquid; (C) viscous (apple sauce); (D) solid (graham cracker); (E) multiple rapid swallow; and (F) rapid drink challenge. Integrated relaxation pressure (IRP) and distal contractile integral (DCI) were 11 mmHg and 1760 mmHg·cm·sec (A), 8 mmHg and 1950 mmHg·cm·sec (B), 7 mmHg and 1600 mmHg·cm·sec (C), 10 mmHg and 1400 mmHg·cm·sec (D), 4 mmHg and 4600 mmHg·cm·sec (E), and 3 mmHg and 0 mmHg·cm·sec (F), respectively.
