Clinical Study Of Computer-assisted Cognitive Training On Post-stroke Cognitive Impairment

Background:China is a country with high incidence of stroke.The annual prevalence rate of stroke is rising and the age tends to be younger.The prevention and treatment of stroke is imminent.Cognitive dysfunction is a common complication after stroke,which not only brings great influence on the life and physical and mental health of the patients,but also reduces the survival rate of stroke patients and increases the mortality rate.Therefore,early recognition,assessment and rehabilitation of post-stroke cognitive impairment is an integral part of stroke care.Researches have confirmed that functional training is the most effective method to improve cognitive function after brain injury,and it is also the most widely used cognitive rehabilitation therapy in clinical.However,besides the traditional artificial cognitive training,that benefited from the combination of computer technology and cognitive rehabilitation therapy,computer-assisted training has gradually become the mainstream trend of cognitive functional training and has broad application prospects in cognitive rehabilitation.Objective:To explore the clinical effect of computer-assisted cognitive training on post-stroke cognitive impairment.Methods:30 patients diagnosed with post-stroke cognitive impairment were selected as subjects in this study,who come from the rehabilitation medicine department of Zhujiang Hospital of Southern Medical University.The subjects were divided randomly into a computer group and a control group,15 cases in each.The control group only received routine rehabilitation and cognitive therapy,and the computer group received the computer-assisted cognitive training based on the 66 nao brain training system which was adopted once a day,five times a week and twelve weeks totally besides the routine rehabilitation and cognitive therapy.The Montreal Cognitive Assessment Scale(MoCA)?Modified Barthel Index(MBI)and the Functional Independence Measure(FIM)were respectively used to evaluate the cognitive functions daily life ability and life independence ability of patients in each group.The time of evaluation was before the treatment and after 12 weeks.Results:The scores of MoCA,MBI and FIM between the two groups were not significantly different before treatment(P>0.05);after 12 weeks of treatment,the scores of MoCA,MBI and FIM in the computer group were significantly higher than those of the control group(P<0.05);the scores of MoCA,MBI and FIM in the computer group were significantly higher than those before the treatment(P<0.05),and the scores of MoCA in the control group was also found significantly different(P<0.05)compared with those before treatment,but there was no significant difference between the scores of MBI and FIM(P>0.05)in the control group;in the computer group except the visual space/executive function and language items in MoCA,the improvements of the name,scores of abstract ability,attention,delayed recall and orientation items were apparently higher than those before treatment(P<0.05),but in the control group there was only the score of delayed recall item improved obviously compared with those before treatment(P<0.05).Conclusion:Computer-assisted cognitive training based on 66 nao brain training system has a positive effect on improving cognitive function after stroke.The treatment effect combined with the traditional artificial training is obviously better than the single artificial cognitive training.It has certain practical significance to promote the patient to recover the cognitive function at an early date,and it is worth further promoting in clinical practice.
