报告20例脑瘫病人选择性后根切断术(SPR)治疗前后体感诱发电位(sep)、运动神经传导速度(MCV)检测结果。
Somatosensory evoked potential (SEP) and motor conduction velocity (MCV) were studied in 20 patients with cerebral palsy treated by selective posterior rhizotomy (SPR).
方法应用经皮质、脊髓电刺激运动诱发电位(MEP)对50例DM患者进行观察。
Methods Motor evoked potentials (MEP) by electrostimulation in cerebral cortex and spinal cord were performed in 50 patients with DM.
结果2 0例周围神经传导速度及诱发电位波幅均有异常，且感觉神经较运动神经损害更重。异常率与疗程、病程成正相关性。
Results The peripheral nerve conduction velocity and evoked potential amplitude are all abnormal in 20 patients and the disorders in sensory nerve are more serious than those in the motor one.
