摘　　要：目的 :采用选择性脊神经后根切断术 (SPR )治疗成人脑外伤后下肢痉挛 16例 ,进行步态分析及诱发电位研究。方法 :手术前后进行步态分析及诱发电位测定 ,将痉挛下肢的L2 ～S1的脊神经后跟进行分束 ,将阈值较低神经束切断。结果 :痉挛解除率 90 % ,功能改善率 80 %。步态分析及诱发电位测定均有显著差异P <0 .0 1。结论 :SPR能有效治疗成人脑外伤后肢体痉挛。 47例Objective:Using selective posterior rhizotomy to treat spastic limbs of adult post traumatic brain and using evoked potential and gait analysis to study.Methods:The posterior roots of L 2～S 1 were separated from anterior roots and it were splited into rootlets.The lower threshold rootlets were sectioned after electrical stimutation.Evoked potential and gait analysis were measured in preoperation and postoperation.Result:The selective posterior rhizotomy have been performed in 16 cases.Follow up 4 years.The result of the treatment is satisfactory.The rate of reducing spasticity was 90 percent.and the rate of functional improvement was 80 percent.The study of Evoked potential and gait analysis show that the effect of postoperation is satisfactory.Conclusions:It is successful to treat spastic limbs of adult post traumatic brain with selective posterior rhizotomy.
