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 exercises using PET plastic bottle, based on the Electromyography (EMG). Here, the 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.
