足外翻脑瘫患儿步行时的足底压力特征

摘要

Objective To find the planter pressure characteristic of children with talipes valgus. Methods 20 children with talipes valgus and 20 healthy children with normal walking ability were involved in this research. JPD1600 plantar pressure measurement system was used to perform plantar pressure gait tests in both groups of children. The data of dynamic plantar pressures in five segments of foot were recorded and analyzed with a computer. Results Significant differences were found in plantar contact area, initial contact phase and impulse between two groups. Conclusion The talipes valgus has bad influence on the gait of children with cerebral palsy. Normative rehabilitation is needed to improve the ability of walking.%目的 了解有足外翻表现的脑瘫患儿步行时的足底压力特征.方法 试验组有足外翻的脑瘫儿童20例,对照组为20例具有正常步行能力的健康儿童,应用JPD1600型足底压力测试仪对足底的5个区域进行数据采集,取得足底压力曲线及特征量参数,将正常组与对照组数据进行对比分析,得出足外翻患儿的足底压力特征.结果 在自然行走时,正常足与外翻足足底各区域接触面积占全掌的百分比、着地时相、足底各区域所受冲量占全掌比例都存在显著差异.结论 足外翻对患儿行走时的步态有不良影响,需尽早规范治疗以改善其行走功能的恢复.
