The effect of low frequency repetitive transcranial magnetic stimulation on acute cerebral infarction patients movement function recovery

Objective To investigate low frequency repetitive transcranial magnetic stimulation (rTMS) on acute cerebral infarction (ACI) patients movement function recovery,in order to provide certain reference basis about the further research on low frequency rTMS treatment ACI and clinical application.Methods Sixty patients of ACI with unilateral limb movement function disorder were divided into low frequency rTMS group and control group by table of random digit with 30 cases each.Two groups were given the conventional drug treatment and rehabilitation training,low frequency rTMS group added low frequencyrTMS treatment 10 d on the basis of the above.Before treatment and after treatment 10 d and 40 d in patientswith the U.S.national institutes of nerve function defect score (NIHSS),Fugl-Meyer motion scale (FMA)score and Barthel index (BI) score changes were observed.Results Before treatment the NIHSS,BI score,FMA score in low frequency rTMS group were (16.44 ± 3.29),(36.69 ± 5.97),(31.06 ± 7.43) scores,incontrol group were (16.38 ±4.01),(35.98 ±6.41),(30.87 ±8.56) scores,there was no significantdifference between the two groups (P ＞ 0.05).After treatment 10 d the NIHSS,BI score,FMA score in lowfrequency rTMS group were (8.13 ± 2.18),(56.04 ± 5.21),(48.42 ± 7.73) scores,in control group were(11.23 ± 1.97),(50.12 ±4.88),(42.12 ±8.61) scores.After treatment 40 d the NIHSS,BI score,FMAscore in low frequency rTMS group were (3.11 ± 0.53),(73.29 ± 5.34),(61.63 ± 8.36) scores,in controlgroup were (5.62 ±0.98),(63.96 ±4.46),(52.45 ±7.61) scores.The NIHSS in the two groups aftertreatment 10 d and 40 d was significantly lower than that before treatment (P ＜ 0.05),BI score and FMAscore was significantly higher than that before treatment (P ＜ 0.05).There were significant differences in theNIHSS,BI score,FMA score after treatment 10 d and 40 d of two groups (P ＜ 0.05).Conclusion Lowfrequency rTMS on ACI patients movement function recovery has obvious role in promotion.
