摘要
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。ＳＥＰ较术前潜伏期缩短者在ＥＢ点为６３％、ＦＯ点４１％、Ｎ１点４１％、Ｐ１点４１％、Ｎ２点５０％，神经传导速度亦较术前明显缩短。对ＳＰＲ的机制进行了讨论。
Somatosensory evoked potential (SEP) and motor conduction velocity (MCV) were studied in 20 patients with cerebral palsy treated by selective posterior rhizotomy (SPR).The results showed that the latency of SEP shortened after SPR in 63% of the patients at the site of EB,47% at FO,N1,P1,respectively,and 50% at N2. The nerve conduction velocity slowed down significantly.The mechanism of SPR was discussed as well.
