Objective To investigate the effect of multi-layer BI sub-executive function training on executive dysfunction in patients with acute vascular occlusive cerebral infarction during recovery. Methods From June 2016 to June 2017, 70 cases of acute vascular occlusive cerebral infarction convalescent patients admitted to the department of neurology of this hospital were selected. According to the random number table, the patients were divided into observation group and control group, with 35 cases each.The control group was given regular rehabilitation guidance after stable condition, and the observation group was supplemented with multi-level executive function comprehensive training on the basis of the control group. The intervention time was 4 weeks.Before and after the intervention, patients' cognitive function, motor function, executive function and quality of life were assessed by neurological deficit score (CSS), simple mental state scale (MMSE), daily activity Barthel index (MBI), behavioral evaluation scale (BADS) and WHO Quality of Life Rating Scale (WHOQOL-100). Results After intervention, CSS scores in the observation group were lower than those in the control group, with statistically significant differences(P<0.05), while MMSE and MBI scores were higher than those in the control group, with statistically significant differences (P<0.05). After intervention, the total score of executive ability and score of each dimension in the observation group were higher than those in the control group, and the difference was statistically significant (P<0.05). After intervention, the scores of physical function, social relationship, psychological function, spiritual belief, self-independence and overall quality of life in the observation group were all higher than those in the control group, with statistically significant differences (P<0.05). Conclusions Multi-level executive function comprehensive training can effectively improve the cognitive function and executive function of patients with acute vascular occlusive cerebral infarction in the convalescence stage, which is beneficial to the prognosis of patients and improve their quality of life.
