Abstract

There is a tendency that the elderly persons decline in feeding and swallowing. It is known that the oral training such as a facial exercise has an effect to facilitate a smoothness swallowing motion. This paper describes a perspective on measurement and evaluation of face movements in the oral training practices, based on the Electromyography (EMG). Here, the zygomaticus major and minor muscles, and orbicularis oris muscle were focused for an evaluation. As a result of APDF analysis, it could be confirmed that the motion of puffing the cheeks had an effect to enhance the activity of the orbicularis oris muscle.
