摘　　要：目的探讨肌电定位注射A型肉毒毒素(BTX-A)定位刺激电流强度与疗效之间的关系。方法15例痉挛型脑瘫患儿接受肌电定位下BTX-A阻滞术治疗,根据患儿体重和修改的Ashworth评分确定BTX-A剂量。对疗效持续时间与诱发肌肉收缩的最小电刺激强度的关系进行分析。结果电流强度与BTX-A的疗效持续时间呈负相关(r=-0.769,P=0.01)。结论在应用绝缘针注射BTX-A时,应该在所需电流强度较小的部位注射。Objective To investigate the correlation between current and therapeutic effect of block myoelectricity fixed Botulinum Toxin A （BTX-A） injection in cerebral palsy. Methods 15 children with spastic cerebral palsy were treated with BTX-A block injection under block myeelectrieity fixing. The dose of BTX-A was identified with the weight of the child and the Modified Ashworth Scale. The correlation between current and period in effect was analyzed. Results There was negative correlation between current and period in effect （ r=- 0. 769,P =0. 01 ）. Conclusion The BTX-A should be injected where the fixed current is less.
