学龄期脑性瘫痪儿童髋关节发育与髋周肌肉状况的相关性分析

Correlation between development of hip joint and the ambient muscle tone in school-age children with cerebral palsy

目的探讨学龄期脑性瘫痪(简称脑瘫)儿童髋关节发育与髋周肌肉状况的关系。方法 2015年4月至6月在广州康复实验学校进行康复训练的脑瘫患儿56例,其中痉挛型41例,不随意运动型9例,共济失调型4例,混合型2例;双瘫37例,四肢瘫16例,偏瘫3例。对全部患儿进行髋关节X线片检查,评定股骨头外移百分比(MP值),并且评定髋关节屈曲、内收、内旋肌肌张力、髋关节伸展、外展、外旋肌肌力。结果 56例脑瘫患儿中髋关节发育基本正常21例(37.50%),半脱位32例(57.140%),全脱位3例(5.36%)。Spearman相关分析显示,MP值与髋关节屈曲、内收、内旋肌肌张力呈正相关(P<0.05),与髋关节伸展、外展、外旋肌肌力测试结果均呈负相关(P<0.05)。结论学龄期脑瘫儿童髋关节发育与髋周肌肉状况相关。

Objective To explore the correlation between the development of hip joint and the ambient muscle tone in school-age children with cerebral palsy. Methods Totally 56 children with cerebral palsy（41 spastic children, 9 athetoid children, 4 dystaxia children, 2 children mixed with spasticity and athetoisis, 37 diplegia, 16 quadriplegia and 2 hemiplegia） in Guangzhou Rehabilitation Experimental School were recruited. All subjects received X-ray examinations to analyze the value of MP. Both the muscle tone of hip flexation, adduction,and intorsion and the muscle strength of hip extention, abduction and extorsion were tested. Results In 56 patients,21 cases（37. 50%） showed generally normal hip development,32 cases（57. 14%） showed half dislocation of hip joint and 3 cases（5.36%） showed total dislocation of hip joint. Spearman correlation analysis showed that the value of MP was positively correlated with the muscle tone of hip flexation, adduction, and intorsion（P〈0.05） and was negatively related to the muscle strength of hip extention,abduction and extorsion（P〈0.05）. Conclusion There is correlation between the development of hip joint and the ambient muscle tone in school-age children with cerebral palsy.
