Abstract:
The purpose of this investigation was to examine the temporal differences among three measures of pharyngeal stage transition in 40 normal subjects. The measures were (1) Pharyngeal Delay Time (PDT), (2) Stage Transition Duration (STD), and (3) Delayed Pharyngeal Swallow (DPS). Results showed a significant difference between younger and older subjects for PDT and STD but not for DPS. No gender differences were observed. These data on normal subjects will be used for comparisons with stroke patients in future research.
