Research Abstract

In this study, we aimed to obtain basic data for developing a new method to induce swallowing in patients with dysphagia, to analyze the effective stimulation conditions of pharyngeal regions that induce swallowing. The threshold for "urge to swallow due to a sensation of water accumulation" was 1.4±0.3 mA for 10 Hz and 1.2±0.3 mA for 15 Hz. Frequencies of the total number of swallows in 30 seconds, and the number of swallows in the last 15 seconds significantly increased in response to pharyngeal stimuli. The resulting increased voluntary swallowing frequency suggests potential clinical applications for this technique
