Effects of an Exercise·Cognitive Dual-Task Program on Cognitive Function, Self-Efficacy and Gait Function variable in Older Adults with Mild Cognitive Impairment

In this study, 23 elderly people aged 65 years or older diagnosed with mild cognitive impairment were randomly divided into an exercise and cognitive dual-task program group (n=7), a single cognitive training program group (n=8), and a control group (n=8). For 8 weeks, aerobic exercise was performed for 20 minutes three times a week and cognitive training was performed for 20 minutes three times a week. The change in cognitive function MoCA-K scores following 8 weeks of intervention showed significant improvement in the dual task group and single cognitive training program group before and after the intervention in each group, but there was no significant difference in the control group. In terms of memory/delayed recall scores, there was a significant improvement in the dual task group and the single cognitive training program group before and after the intervention in each group, but there was no significant difference in the control group. Self-efficacy showed significant improvement in the dual task group before and after the intervention for each group, but there was no significant difference between the single cognitive training program group and the control group. In terms of physical strength related to walking ability, there was no significant difference in F8WT and TUG before and after intervention in each group among the dual-task group, cognitive training group, and control group.
