A型肉毒毒素治疗痉挛型双瘫患儿疗效的表面肌电分析

摘要

目的 观察A型肉毒毒素(BTX-A)注射治疗痉挛型双瘫前后表面肌电图(sEMG)的变化.方法 50例痉挛型双瘫患儿于小腿三头肌注射BTX-A,治疗前后分别用临床方法和sEMG进行评价.结果 治疗后患儿功能位测试小腿三头肌的肌电积分值降低,测试足背屈角减小.结论 sEMG可以客观评价BTX-A注射后痉挛型双瘫患儿肌张力的变化.%Objective To evaluate the effect of Botulinum Toxin A (BTX-A) on spastic diplegia by surface electromyography (sEMG).Methods 50 children with cerebral palsy following spastic diplegia were recruited and injected with BTX-A in triceps surae.They were assessed with the clinical test and the sEMG before and after the treatment.Results After the treatment the integrated electromyography(iEMG) of triceps surae and foot dorsiflexion angle all decreased Conclusion sEMG is an objective tool to assess the change of spasticity in children with diplegia after BTX-A injection.
