Abstract: Objective: To explore the effects of dual task training in elderly patients with Vascular Mild Cognitive Impairment (VaMCI). Methods: From March 2019 to February 2020, 71 elderly patients with VaMCI were selected from 3 tertiary grade A general hospitals and divided into the experimental group (35 cases) and the control group (36 cases). Health education was given to the two groups respectively. The experimental group received three months of dual-task training on the basis of health education. Before the intervention, 3 months after the intervention and 1 month after the intervention, wearable gait analyzer was used to measure the stride time, stride length, step speed and stride frequency of the study subjects under natural walking and dual task walking. The Timed Up & Go Test was used to evaluate the balance function of the study subjects. Results: Compared with the control group, the experimental group improved the stride time, stride length, step speed and stride frequency under natural walking and dual task walking at 3 months of intervention and 1 month after intervention, and the time consumption of Timed Up & Go Test was reduced, with statistically significant differences (P<0.05). Conclusion: Dual task training can effectively improve the gait and balance function of the elderly with VaMCI.
