Abstract

Swallowing disorders robs persons of pleasure of eating. The quality of life (QOL) of patients falls much. We propose simultaneous measurement, impedance pharyngography (IPG) and swallowing sound for evaluations of swallowing. IPG is based on neck electrical impedance, which is influenced by cross sectional area of near epiglottis. There was a problem which the changes of IPG did not match pharyngeal phase in some patients or the aged. The swallowing sound was measured with a microphone attaching on the neck. The components of higher than frequency 30 Hz in swallowing sound were made by bolus passing through pharynx. Therefore swallowing sound phase matched pharyngeal phase and reflected characteristics of bolus. The measurement of swallowing using IPG is improved with swallowing sound measurement. This method can be applied for diagnosis of swallowing disorders.
