| Objective: To explore the effects of repetitive transcranial magnetic stimulation (rTMS) on cognitive function, central motor conduction time and balance ability in patients with post-stroke cognitive impairment. Methods: Totally, 200 patients with post-stroke cognitive impairment were randomly divided into 4 groups, 50 patients in each group. The control group was given conventional basic treatment and cognitive function training, the low-frequency group was given low-rTMS on the basis of the control group, the high-frequency group was given high-rTMS on the basis of the control group, and the combined group was given high and low rTMS on the basis of the control group. The cognitive function, central motor conduction time and balance ability of the 4 groups after treatment were compared and analyzed. Results: Before treatment, there was no significant difference among the 4 groups in the comparison of the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), Berg Balance Scale (BBS), Modified Barthel Index (MBI), and central motor conduction time (P>0.05). After treatment, the MMSE, MoCA, BBS, and MBI scores in the 4 groups all increased, and the central motor conduction time decreased. After treatment, the MMSE, MoCA, BBS and MBI scores in the combined group were significantly higher, and the central motor conduction time was significantly shorter than in the other groups (P<0.05); The MMSE, MoCA, BBS, and MBI scores in the control group were significantly lower, and the central motor conduction time was significantly shorter than those in the other groups (P<0.05). Conclusion: Low frequency combined with high frequency rTMS has a good therapeutic effect on patients with post-stroke cognitive impairment, which can significantly improve the cognitive function and balance ability of patients, shorten the central motor conduction time, and improve the ability of daily living activities. |
