1. A system for diagnosing swallowing disorders of a patient comprising: a manometer adapted to be inserted along the upper aerodigestive tract in the vicinity of the patient's pharynx and esophagus to provide a series of pressure measurements at different points along the patient's pharynx; a computer receiving the series of pressure measurements at different points and executing a stored program to: (a) link the pressure measurements during a swallowing to different multiple predetermined locations along the pharynx; (b) analyze pressure as a function of time in the predetermined locations to generate a set of pressure based predetermined parameters; (c) process the pressure based predetermined parameters to derive image-describing diagnostic parameters and values that conform to a modified barium swallow impairment profile (MBSImP); and (d) output the image-describing diagnostic parameters and values to a user.
