探索了磁诱导对脑卒中患者运动康复的影响,设计了磁场诱导大脑自发脑电的实验方法,通过极低频(16 Hz)、低强度(20 m T)脉冲磁场作用于8位脑卒中患者的患侧脑区,同时采集静息状态下的脑电信号并对数据进行分析,利用Jebsen-Taylor手功能测试(JTT)和结合简化Fugl-Meyer运动功能评定量表和改良的Barthel指数评定量表评定康复效果。实验结果显示,磁诱导后量表评分显著升高,脑电高频段能量在运动皮层处有所增加。研究表明,磁诱导技术对脑卒中病人的康复有积极影响,可与传统康复疗法相结合在神经康复中起到辅助作用。
This paper explores the effects of magnetic induction on motion rehabilitation in stroke patients.The extreme low frequency(16 Hz) and low intensity(20 m T) pulsed magnetic field was applied on the affected brain side of 8 stoke patients.The magnetic fieldinduced electroencephalography( EEG) signals in resting state were collected and analyzed.The Jebsen-Taylor hand function test( JTT)behavioral parameters combined with the simplified Fugl-Meyer motion function and the modified Barthel index rating scales were utilized to evaluate the rehabilitation effect.The experimental results show that after magnetic induction,the scores of the rating scales were significantly increased and the power of the high frequency rhythm increased upon the motion cortex.The study shows that the magnetic induction technique has positive effect on the rehabilitation of the stroke patient and could be combined with the traditional rehabilitation therapy to assist the neural rehabilitation.
