摘要：
Tools, methods and apparatus are provided that may be used to identify ineffective swallowing in the subject, including ineffective swallowing due to an obstruction, and may further be used to determine risk of aspiration in the subject. In one aspect, a method includes accessing intraluminal impedance measurements and pressure measurements obtained from the pharynx and/or esophagus of a subject during clearance of a bolus from the mouth and/or throat of the subject. The method further includes combining and analyzing the intraluminal impedance and pressure measurements to derive a value for one or more pressure-flow variables in the pharynx and/or esophagus on the subject. The swallowing motor function in the subject is assessed by comparing the value of the pressure-flow variables with a predetermined pharyngeal and/or esophageal reference value for the one or more pressure-flow variables.
