痉挛型偏瘫患儿下肢等长肌力分析

Isometric Muscle Strength in Lower Extremity of Children with Spastic Hemiplegia

目的比较痉挛型偏瘫患儿下肢患侧与对侧肌群间等长肌力的差异,并且分析不同年龄偏瘫患儿的肌力表现。方法对17例痉挛型偏瘫患儿采用手持式肌力测定仪测定患儿下肢髋、膝、踝等部位肌群的肌力,比较患侧和对侧下肢肌群间肌力差异以及不同年龄患儿的肌力表现。结果患侧下肢的肌力明显弱于对侧;在较小年龄阶段,患侧下肢全面弱于对侧,而在较大年龄阶段主要表现为远端肌力下降。结论对痉挛型偏瘫患儿进行力量训练时,早期应该注意提高下肢所有肌群的肌力,在较大年龄阶段应该更加强化远端肌群的肌力训练。

Objective To compare the isometric muscle strength of muscle groups in the lower extremities of children with spastic hemiplegia among sides or ages. Methods17 spastic hemiplegic children were measured the muscle strength of hip,knee and ankle muscle groups with hand-held dynamometry （HHD）. ResultsMuscle strength was weaker in the involved side than in the other side. In younger children,it was weaker of overall extremity,while in the older it was of the distal end mainly. ConclusionWhen applying strength training to spastic hemiplegic children,it is important to notice strength of all groups in lower extremity in younger children and the distal groups in older ones.
