摘    要:目的观察偏瘫患者恢复期康复训练前后双手食指伸屈运动过程中脑磁图(MEG)变化。方法对1例偏瘫患者应用MEG记录双手食指伸屈运动时的脑电磁波并与MRI叠加形成磁源性影像(MSI),对比康复训练前后MEG变化。结果两次MEG检测右侧半球皮质均无运动诱发出脑磁反应,左侧半球均有运动诱发反应;第1次和第2次潜伏期分别为-34.2ms和-61.7ms,部位向内前下移位,MSI显示兴奋的皮质位于中央前回,第2次激活的脑皮质体积(9569.6m3)明显大于第1次(2309.7m3);第1次食指运动未诱发右半球体感反应;第2次食指运动诱发了右半球的体感反应,潜伏期为91.1ms,MSI显示兴奋的皮质位于中央后回。结论脑卒中患者皮质感觉功能先于运动功能恢复,未损半球经康复训练后功能明显增强。

关 键 词:食指运动  康复训练  运动皮质  脑磁图描计术  磁共振成像

Abstract:Objective To observe the changes of magnetoencephalography (MEG) during stretching and flexing forefinger in one hemiplegic patient before and after rehabilitation training.MethodsThe cerebral electromagnetic wave of one hemiplegic patient during stretching and flexing both forefingers was recorded by MEG and superposed with magnetic resonance imaging (MRI) to form magnetic source imaging (MSI). The changes of MEG before and after rehabilitation training were analyzed.ResultsThere was no movement evoking magnetic fields in right hemisphere motor cortex at two MSI detections, but detected in left hemisphere motor cortex. The latent period of the first and the second detection was -34.2 ms and -61.7 ms respectively. The exiting motor cortex was located in precentral gyrus. The exiting motor cortex at the second detection was located more front medial and low than at the first detection. The volume of the exiting motor cortex (9569.6 m3) at the second detection was more larger than the first detection (2309.7 m3). There was no movement evoking somatosensory magnetic fields in right hemisphere motor cortex at first MSI detection, but found at the second detection, the latent period was 91.1 ms, and the exiting cortex was located in postcentral gyrus.ConclusionThe cortex somatosensory function of patient with stroke recovers early than the motor function and the uninjured hemisphere function can improve obviously after rehabilitation training.
Keywords:firefinger movement  rehabilitation training  motor cortex  magnetoencephalography  magnetic resonance imaging
