Clinical Study Of Transcranial Direct Current Stimulation On Post-stroke Executive Impairment

Objective:Post-stroke executive impairment?PSEI?patients with dysfunction,poor understanding,inability to complete instructions,thinking solidification,extraction disorders,attention deficits,etc.^[1],is part of cognitive function.Patients with executive dysfunction can not actively cooperate with the completion of rehabilitation training,reducing the ability of daily living,prolonging the treatment cycle,affecting the functional recovery effect after stroke,and consuming human and material resources,which brings a heavy burden to the family and society.In recent years,transcranial direct current stimulation?tDCS?is a non-invasive technique.As an accelerator of brain function recovery,it has been cited in recent years for the recovery of various functions after stroke,especially in cognitive dysfunction.Rehabilitation is receiving more and more research and attention,but most of the research in the literature is the analysis of the effect of tDCS on the overall cognitive function of patients after stroke.There is no research on the cognitive branch after stroke alone.This study was to investigate the effect of tDCS on specific executive dysfunction in the early and middle strokes after randomized,controlled,double-blind experiments,and objectively evaluate the therapeutic effect through the scale.Methods:Thirty cases of inpatients who met the inclusion and exclusion criteria from October2017 to October 2018 in the Department of Rehabilitation Medicine,the First Hospital of Shanxi Medical University were selected.They were randomly divided into experimental group 15 cases and control group 15 cases.The experimental group was given conventional cognitive rehabilitation training plus tDCS treatment,the control group was given conventional cognitive rehabilitation training plus false stimulation,and the tDCS anode stimulating electrode was placed in the left dorsolateral prefrontal cortex?DLPFC?,the cathode non-active electrode The piece is on the right shoulder.The results of the Montreal cognitive assessment scale?MoCA?,the Trail Making Test?TMT?,and the Modified Barthel Index?MBI?were performed before and after treatment.assessment.Results:There were no significant differences in the results of the three scales of MoCA,TMT-A,TMT-B and MBI scores between the experimental group and the control group before treatment?P>0.05?.After 3 weeks of treatment with tDCS,the MoCA score,MBI score,and the time-consuming TMT-A and TMT-B in the two groups were significantly improved compared with those before treatment?P<0.05?.The MoCA score,MBI score and TMT-A,TMT-B consumption time were better than the control group,and the difference between the experimental group and the control group was statistically significant?P<0.05?.Conclusion:As an accelerator of brain function recovery,tDCS can significantly improve the executive dysfunction in patients with early and middle stroke after a short period of time,and the overall cognitive function and daily living ability of patients after tDCS treatment are significantly improved,reducing the cost of family and material resources and returning to the family society as soon as possible is worth further promotion in future clinical work.
