Study Arms (1)

Intervention

EXPERIMENTAL

20 elders (10 mild cognitive impairment, 10 cognitive normal elders) those who received oral vibrational stimulation

Device: Oral Vibrational Stimulation

Interventions

Oral application of vibratory stimulus : With the oral equipment, which is similar to the device generally used to prevent teeth grinding in dental clinics, 15-second vibratory and 15-second non-vibratory stimulus are given repeatedly for about 5 minutes using a vibrator that has a strength less than or equal to the vibratory stimulus of a smartphone (3.3V, 166Hz, maximum 180Hz). A stimulus of two times for 5 minutes, a total of at least 10 minutes is conducted for 10 days in a hospital or designated place.
