ABSTRACT:
Dysphagia, or difficulty in swallowing, can cause choking, aspiration of food or liquid into the lungs, incomplete administration of medication, and discomfort to the victims. A method is provided for evaluating the severity of Dysphagia. The method comprises providing at least two sets of orally ingestible materials, each set of orally ingestible material comprising at least two compositions of like materials differing significantly in one property selected from the group consisting of viscosity, adhesiveness, cohesiveness and yield force. A patient ingests a first one of the at least two compositions from a first set of the at least two sets, examining the patients for a dysphagic response to the ingestion of the first one of the at least two compositions, and noting any dysphagic responses. Steps b), c) and d) are repeated for another set of orally ingestible materials which another set of the at least two sets of orally ingestible materials characterizes a property that is different from a property selected from the group consisting of viscosity, adhesiveness, cohesiveness and yield force characterized by the first one of the at least two compositions from a first set of the at least two sets of orally ingestible material.
