Effect of different frequency of repeated transcranial magnetic stimulation on post-stroke cognitive impairment
Objective To investigate the effect of different frequency of repetitive transcranial magnetic stimulation(rTMS)on post-stroke cognitive impairment.Methods A total of 60 patients with post-stroke cognitive impairment combined with dysphagia were selected from Xuzhou Central Hospital,Jiangsu Province from September 2021 to February 2023,and were divided into control group,low frequency group,and high frequency group according to random number table method,with 20 cases in each group.The control group was given routine swallowing function training and cognitive function re-covery training,the low-frequency group was given routine swallowing function training and right low-frequency rTMS treatment,and the high-frequency group was given routine swallowing function training and left high-frequency rTMS treatment.After four weeks of treatment,the improvement of cognitive function score,swallowing function score,and nutri-tional status score of the three groups before and after treatment were assessed.Results After treatment,the videofluoro-scopic dysphagia scale and penetration aspiration scale scores of the three groups were lower than those before treatment,and those of the high frequency group were lower than those of the low frequency group and the control group,while those of the low frequency group were lower than those of the control group,and the differences were statistically significant(P＜0.05).After treatment,mini-mental state examination,Montral cognitive assessment,and mini nutritional assessment scores in the three groups were higher than those before treatment,and those of the high frequency group were higher than those of the low frequency group and the control group,and those of the low frequency group were higher than those of the control group,and the differences were statistically significant(P＜0.05).Conclusion High-frequency rTMS can better im-prove the cognitive function and swallowing function of pa-tients with post-stroke cognitive impairment and dysphagia than lowfrequency rTMS and conventional cognitive function recovery training.
