The Effects of Facial Exercise on Mental Health, Facial Expression and EEG in Community-Dwelling Older People

Abstract

Although it is well documented that exercising is good for the mental health and cognitive function as well as the physical condition in elderly people, exercising is difficult in elderly individuals with a low motor function. To develop an exercise program targeting elderly individuals unsuited for whole-body exercises, we assessed the effects of facial exercises on the mental health and mood in healthy elderly people. Community-dwelling older adults (N = 75, age range = 65-87 yrs) were randomly divided into a facial exercises group and a wait-listed control group. A facial exercises program of 30 min was given twice a week for 12 weeks. This program consisted of rhythmic facial movement, muscle stretching, facial yoga, and Tanden breathing. The GHQ-12 for mental health were administered to both groups before and after the 12-week study period. In addition, facial expression and EEG were measured. Fifty-three participants completed the protocol. In the intervention group, the GHQ-12, facial expression, and α wave in frontal lobe improved post-intervention. These results suggest that facial exercises are effective in improving the mental health, facial expression, α wave in frontal lobe of elderly people, and that exercises may be useful as a therapeutic modality in this population.
