Objective To explore the influences of transcranial direct current stimulation(tDCS)in combination with cognitive-motor dual task training(CMDT)on memory and executive function in patients suffering from post-stroke cognitive impairment.Methods A total of 75 stroke patients were randomly divided into the tDCS group,the CMDT group and the combined group,each consisting of 25 cases.All patients in the three groups received routine rehabilitation treatment.The tDCS group underwent tDCS stimulation of dorsolateral prefrontal lobe(DLPFC)of the region,the CMDT group received CMDT and the combined group received CMDT on the basis of tDCS treatment.The fourth edition of the Wechsler Memory Scale(WMS-IV),Wisconsin Card Test(WCST),Montreal Cognitive Assessment(MoCA)and Modified Barthel Index(MBI)were used to evaluate the overall cognitive function,memory,executive function,and daily living ability of the patients before and 4 weeks after treatment,respectively.Results Before treatment,there were no significant differences in the evaluation indices between the three groups(P＞0.05).After 4 weeks of treatment,the scores of WCST,WMS-IV,MoCA and MBI in the three groups were improved compared with those before the treatment(P＜0.05),and the combined group was significantly superior to the tDCS group and the CMDT group(P＜0.05).Conclusion The combination of tDCS and CMDT can improve the cognitive function after stroke,and at the same time exert a synergistic effect on memory and executive function.
