Abstract： Objective： To observe the clinical effect of Baduanjin combined with transcranial direct current stimulation for mild cognitive impairment after stroke. Methods：A total of 94 cases of patients with mild cognitive impairment after stroke were divided into the control group and the observation group according to the random number table method，with 47 cases in each group. The control group was treated with transcranial direct current stimulation，and the observation group was intervened with Baduanjin based on the treatment of the control group. The clinical effects in the two groups were compared. Before and after treatment， the changes in cognitive function， activities of daily living and nerve electrophysiology indexes in the two groups were observed. Results：The total effective rate was 91.49% in the observation group，higher than that of 74.47% in the control group(P＜0.05). After treatment，the scores of Montreal Cognitive Assessment(MoCA)， Mini- Mental Status Exam(MMSE)， Functional Independence Measure (FIM) and Modified Barthel Index(MBI) in the two groups were increased when compared with those before treatment(P＜0.05)，and the scores of MoCA，MMSE，FIM and MBI in the observation group were higher than those in the control group(P＜0.05). After treatment，P300 latency in the two groups were shortened when compared with those before treatment(P＜0.05)，and P300 amplitude were increased(P＜0.05)；the P300 latency in the observation group was shorter than that in the control group(P＜0.05)， and the P300 amplitude was larger(P＜0.05). Conclusion：Baduanjin combined with transcranial direct current stimulation has a definite curative effect in treating patients with mild cognitive impairment after stroke， which can improve cognitive function，nerve electrophysiology indexes and activities of daily living.
