脑性瘫痪患儿术前爬行能力与选择性脊神经后根切断术后下肢功能改善的相关分析

Predictive value of crawling ability for prognostication of the functional amelioration of children with cerebral palsy after selective posterior rehizotomy

目的 分析术前爬行能力与术后下肢功能特别是独立行走能力的关联。方法 以量化功能的方式评估选择性脊神经后根切断术后下肢功能。将爬行功能分为 A～ D 4个等级，同时将下肢功能分别量化，观察各级患儿手术前、后的功能变化，并统计分析术前、后的功能差异。结果 术后肌张力明显降低，下肢各项功能显著改善；术前爬行能力良好的患儿术后下肢各项功能与独立行走与爬行能力差的患者有显著性差异。结论 术前爬行能力对判断手术预后具有参考价值。

Objective To evaluate the value of crawling ability as predictor of walking postoperatively.Methods To observe the function of lower limbs with quantitative functional measurement,and analyze the relation between walk ability after SPR and preoperative crawling stage. Results Muscle tone was significantly decreased,and the development of function of lower limbs was obviously.The achievement was continuously in 1 year and 2 year follow up group.The ability of crawling was closely related with walk ability after SPR. Conclusion SPR decreases spasticity and increases lower estremity range of motion in children with cerebral palsy and appears to be associated with functional improvements.The ability of crawling is a predictive reference of ability to walk after selective posterior rhizotomy.
