摘要 目的探讨表面肌电在痉挛型双瘫患儿腰背肌功能评定中的价值。方法选取30例痉挛型双瘫的患儿进行临床康复训练,治疗前、后采取表面肌电仪记录患儿腰背肌的肌电信号,同时进行临床评估并进行分析比较。结果治疗后患儿腰背肌最大随意收缩(maximal voluntary contraction,MVC)的平均肌电值(averaged electromyo-gram,AEMG)较治疗前升高[竖脊肌:(79.86±42.32)μV比(53.35±31.03)μV;多裂肌:(91.25±41.82)μV比(62.17±21.58)μV,P<0.05]。治疗后,患儿腰背肌肌力手法肌力检查(manual muscle testing,MMT)分级为4.162±0.530,较治疗前(2.957±0.120)增加(P<0.05),提示患儿治疗后的腰背肌肌力较治疗前提高。结论表面肌电仪可以作为评估痉挛型双瘫患儿腰背肌肌力的客观评估方法。 Objective To study the value of surface electromyography in the evaluation of back muscle function in children with spastic diplegic cerebral palsy.Methods Thirty children with spastic diplegia underwent clinical rehabilitation training.The back muscle function was assessed with the recorded electromyographic signal before and after treatment. Results Compared with the values before treatment,the averaged electromyogram during maximal voluntary contraction significantly increased after treatment[erector spinae:(79.86±42.32)μV vs(53.35±31.03)μV;multifidus:(91.25±41.82)μV vs(62.17±21.58)μV;P<0.05].In addition,the manual muscle testing grades of back muscle strength increased from 2.957±0.120 before treatment to 4.162±0.530 after treatment(P<0.05).Conclusion Surface electromyography provides a satisfactory evaluation of back muscle function in children with spastic diplegia.
