Methods: a total of 48 stroke patients who were hospitalized in Beijing Rehabilitation Hospital of Capital Medical University from October 2020 to April 2021 and met the inclusion and exclusion criteria were randomly divided into intervention group (n=24) and control group (n=24). The control group received routine rehabilitation training. The intervention group received cognitive-motor dual task training on the basis of routine rehabilitation training, and the training time and frequency were the same for the two groups. The intervention training lasted for 8 weeks. Changes in patients' balance function and ADL were assessed before and after 8 weeks of intervention, including Berg Balance Scale, Fugl-Meyer Balance Scale and ADL score. Changes in scores of each test were recorded for statistical analysis. Results: after the end of the experiment, intervention group 2 and control group all completed the study 8 weeks after intervention, intervention group and control group showed significant improvement in the three tests compared with before intervention. When standing up while sitting and standing without support, the Berg balance scale score of intervention group was significantly higher than that of control group. Fugl-Meyer and ADL scores of the intervention group under the dual task were significantly higher than those of the control group. After three tests, statistical analysis showed that the differences were statistically significant (P <0.05). Conclusion: the cognitive-motor dual task training can improve the balance function and ADL of stroke patients, and the dual task training combined with the routine rehabilitation training is more conducive to the recovery of balance function of patients, so as to improve the ADL.展开更多
