Conditions

Breathing-Swallowing Coordination, Dysphagia Rehabilitation

Brief summary

Dysphagia is caused by multiple factors, and respiratory-swallowing discoordination is considered to be one of the factors. The investigators recently developed a visual and auditory breathing-swallowing coordinated training device. In this study, investigators examined the validity of a this device for healthy subjects. The investigators will examine which respiratory phase the swallowing occurs when the swallowing is started in accordance with the signal lighting and voice of this device.

Interventions

DEVICEVisual and Auditory Breathing-swallowing Coordinated Training device

This device has a structure in which a band wrapped around the chest detects the respiratory phase from changes in the lung volume, and the connected device lights a signal and sounds a sound.
