Clinical Study Of Transcranial Direct Current Stimulation On Attention Dysfunction After Stroke

Objective:Attention deficit is more common after stroke,which can cause patients' cognitive,motor function and activities of daily life decline,and has a certain relationship with poor prognosis,affecting the rehabilitation effect after stroke.Transcranial direct current stimulation,as a non-invasive brain stimulation technology,can regulate specific areas of the brain.In recent years,most of the research on transcranial direct current on cognitive function has focused on the study of overall cognitive function and lack of other cognitive areas.This study will explore the effect of transcranial direct current combined with cognitive training in the recovery of attention deficit after stroke.Methods:A total of 30 patients who met the inclusion and exclusion criteria in the Department of Rehabilitation Medicine of the First Hospital of Shanxi Medical University from November 2018 to December 2019 were selected,and the patients were randomly divided into the experimental group and the control group using the random number table method.All patients were given conventional rehabilitation therapy and secondary preventive medicine treatment plan for stroke.The experimental group was given tDCS stimulation plus cognitive function training,and the control group was given tDCS sham stimulation plus cognitive function training.The tDCS anode electrode was placed in the left dorsal prefrontal lateral region,and the cathode was placed in the contralateral shoulder.The direct current intensity was 1.5 mA,20 minutes each time,once a day,5days a week for 3 weeks.Before and after 3 weeks of treatment,the Montreal Cognitive Assessment Scale(MOCA),Stroop color word test,and modified Barthel index wereused to evaluate the two groups of patients.Results:After 3 weeks of treatment,MOCA,the correct number and time of Stroop color word test and MBI scores in the two groups were improved compared with the previous(P <0.05),and the experimental group was better than the control group,the difference was statistically significant(P <0.05).Conclusion:tDCS combined with cognitive function training can not only improve the attention of patients after stroke,but also promote the improvement of patients' daily life ability.
