Is Visual Memory Improved by Daily Saccadic Eye Movement in Institutionalized Elderly Person?:

Yongnam Park, Youngsook, Bae

Abstract


Background: Aging results in a decline in a number of cognitive abilities, including visual memory (VM) and visual discrimination (VD). Since common cortical networks subserve eye movement and attention, voluntary eye movement may improve visual attention. The aim of this study was to identify the improvement in VM and VD, after implementing a saccadic eye movement (SEM) in the institutionalized healthy elderly.

 

Material and Methods: The study involved a sample of 36 participants (29 women and 7 men), and the mean age was 79.03 years (range 76-84 years). They were randomly allocated to the experimental group (n = 16) and control group (n = 20). Participants in the experimental group performed SEM, SEM performed 5 times per week for 4 weeks: twice daily at the same time in the morning and afternoon. The program was carried out for 3 minutes, and it consisted of SEM. The target’s moving frequency was set at 0.5 Hz. VM and VD at the baseline and post-intervention were measured.

 

Results: VM significantly improved in the experimental group (p < 0.01), and significant differences were observed compared to the control group (p < 0.01). But, VD was not changes.

 

Conclusion: The results demonstrate that the SEM improves VM more than VD. In conclusion, SEM was effective interventions for improving VM in institutionalized elderly persons.
