Clinical Analysis Of Low Frequency Repetitive Transcranial Magnetic Stimulation On Treatment Of Upper Extremity Muscle Spasm After Ischemic Stroke

Objective:To observe the therapeutic effect of low frequency repetitive transcranial magnetic stimulation on upper extremity muscle spasm and motor function after acute ischemic stroke.Method:Forty patients who met the criteria were included in the study,They were randomly divided into two groups,20 cases of real and sham stimulate group.Both groups were given basic drug therapy and rehabilitation training.In the stimulation group,1HZ r TMS 100% MT was administered to the upper extremity projection area of c M1 and sham stimulation group was stimulated with 20% MT of 1HZ r TMS in the same area,there was no difference in the other intervention.there were assessments at before treatment(T1)and after 4 weeks(T2)assessment scale including wrist and elbow flexion MAS,ULFMA and BI index assessment scale.Results:1.There was no significant difference in baseline data between the two groups;2.There was no significant difference in MAS,ULFMA and BI scores before treatment between the two groups(P>0.05);3.Wrist flexion and elbow after treatment in the true stimulation group The score of flexion MAS was significantly lower than that before treatment(P < 0.05).ULFMA and BI scores were significantly higher than before treatment(P < 0.05);4.The MAS scores of wrist flexion and elbow flexion in the sham stimulation group were not significantly different from those before treatment(P > 0.05).The ULFMA and BI scores were higher than those before treatment,and the difference was statistically significant(P < 0.05);5.The ULFMA and BI values in the true stimulation group were significantly higher than those in the sham stimulation group(P < 0.001).Conclusion : Low-frequency repetitive transcranial magnetic stimulation can effectively relieve upper limb paralysis in patients with stroke,improve upper extremity motor function and daily living ability.
