Outline of Final Research Achievements

We constructed a swallwing function maintenance and improvement care model using vocalization comprising (a) reading aloud 7000 monosyllables (“Reading”), (b) past-telling for 20 min (“Past-telling I”), and (c) past-telling for 30 min (“Past-telling II”) and validated its effects.
After “Reading,” in healthy elderly individuals, the third RSST(The Repetitive Saliva Swallowing Test）was shortened and the core body temperature, pulse, and surface temperature of the thyrohyoid muscle were elevated. Although oral diadochokinesis (OD) “/ta/” increased after “Past-telling I,” the swallowing time shortened and OD “/ka/” decreased after “Past-telling II.” Weak elderly individuals presented with dry mouths after “Reading” and “Past-telling II.” Furthermore, after “Past-telling II,” chromogranin A levels reduced, sense of fulfillment and enjoyment increased, and sense of anxiety and fatigue reduced as compared to those after “Reading.”
