重復經顱磁刺激治療對腦卒中患者運動功能及MEP的影響
[Abstract]:Objective: repetitive transcranial magnetic stimulation (TMS), as a new non-invasive brain stimulation technique, has been widely used in the study and treatment of stroke patients with dysfunction. At present, there have been a lot of studies on the effect of rTMS on recovery of motor function in stroke patients. However, the rTMS regimen used in this study is limited to the treatment of high-frequency stimulation on the affected side or only the treatment of low-frequency stimulation on the healthy side. The purpose of this study is to investigate the effects of continuous inhibitory-facilitative rTMS on motor function recovery and motor evoked potentials in the affected hemisphere of stroke patients during convalescence.
METHODS: Twenty-nine stroke convalescent patients admitted to the Department of Rehabilitation Medicine of Shandong University Affiliated Provincial Hospital from October 2012 to January 2014 were randomly divided into treatment group (15 patients) and control group (14 patients). Treatment and rehabilitation (including physical therapy, occupational therapy, speech therapy, dysphagia treatment, cognitive function therapy, acupuncture, massage, etc.). 15 patients in the treatment group were treated with rTMS true stimulation. The treatment scheme was: 1 Hz low-frequency true stimulation was performed 15 minutes prior to the normal cerebral cortex upper limb motor area, and then on the affected cerebral cortex. All patients were assessed by Fugl-Meyer upper extremity motor function (FMA) score, Barthel index (BI) score, and exercise-induced motor function (EMF) score before and after 6 weeks of treatment. Potential (MEP) latency and maximum amplitude. All the evaluation results were analyzed by SPSS21.
Results: There was no significant difference in the functional scores between the treatment group and the control group before treatment (P 0.05). Six weeks after treatment, the functional scores of the two groups were higher than those before treatment. FMA score, BI score, MEP latency and maximum amplitude of MEP in the treatment group were significantly improved compared with the control group (P 0.05).
CONCLUSIONS: Continuous inhibitory-facilitative rTMS therapy includes two therapeutic schemes. One is low-frequency magnetic stimulation of the contralateral cerebral cortex motor area. We found that the scheme can reduce the excitability of contralateral cerebral cortex motor area and regulate contralateral cerebral cortex motor area to contralateral cerebral cortex motor area. Excessive inhibition, thus improving the excitability of the affected hemisphere cortical motor areas, to improve the motor function of the affected limbs; the other scheme is to use high-frequency magnetic stimulation of the affected hemisphere cortical motor areas, found that the program can improve the excitability of the affected hemisphere cortical motor areas, thereby improving the affected limbs. We found that on the basis of comprehensive rehabilitation treatment, combined with rTMS treatment, the recovery of limb function in stroke patients was significantly better than that in simple rehabilitation treatment, suggesting that inhibitive-facilitative rTMS treatment can not only significantly promote the recovery of motor function in convalescent stroke patients, but also can adjust both sides. The integration of cerebral hemispheres promotes a new balance between bilateral cerebral hemispheres, which provides a powerful theoretical basis and clinical treatment method for the clinical treatment of limb motor function in stroke patients.
