Evaluation Of The Effect Of Repetitive Transcranial Magnetic Stimulation On Lower Limb Motor Function In Patients With Spinal Cord Injury By Surface Electromyography And Digital Treadmill

Objective There are many clinical rehabilitation methods for spinal cord injury.Repetitive transcranial magnetic stimulation is a new technique which has a treatment for nervous system.Some clinical reports have shown that it can improve motor function of lower extremities in patients with spinal cord injury,however its mechanism of action has not been defined.There is no unified standard for clinical treatment.The study set out to explore the effect of repetitive transcranial magnetic stimulation(i TBS mode)on lower limb motor function in patients with spinal cord injury by using modern methods such as surface electromyography and digital treadmill.Methods 38 patients with incomplete spinal cord injury who met the inclusion criteria were randomly assigned into 2 groups(19 cases in each group).The control group received only routine rehabilitation treatment,including conventional rehabilitation care,medication,limb function training,electrical stimulation treatment,electronic biofeedback treatment,suspension training,physical factor therapy,etc.The experimental group was treated with i TBS stimulation(intermittent theta rhythm stimulation)in the M1 area of the bilateral cerebral hemispheres on the basis of the control group.3 minutes and 20 seconds on each side,6 minutes and 40 seconds on both sides.They were treated once a day,6 times a week,each course of treatment for3 weeks,a total of 3 courses of treatment.Before and after treatment,each patient was collected the root mean square value of quadriceps femoris during maximum isometric contraction,the step length and speed of both lower limbs through the digital treadmill,and were evaluated by score of key muscle groups of lower limbs and daily living ability assessment.Analyze the differences in indicators between the two groups of patients before and after treatment.Results There was no statistical difference in the basic data of the two groups of patients(P>0.05).Before and after treatment,the changes in the quadriceps root mean square value,step length,pace and clinical scale scores of the two groups of patients were statistically significant(P<0.05).Compared with the control group,the experimental group had the quadriceps root mean square value of both lower limbs,step length,pace and clinical scale score improved more significantly(P<0.05).Conclusions Through the systematic evaluation of surface electromyography and digital treadmill,repetitive transcranial magnetic stimulation(i TBS mode)can significantly improve the function of lower extremities in patients with spinal cord injury.
