踝足矫形器对脑瘫患儿异常步态的影响

Effects on abnormal gait pattern in spastic diplegia cerebral palsy children using ankle foot orthoses

目的:研究踝足矫形器对改善痉挛型脑瘫患儿步态的影响。方法:对30例脑瘫患儿配戴踝足矫形器前、后进行步态分析。结果:脑瘫患儿配戴踝足矫形器后,跨步长、步速明显提高,其中跨步长由0.38±0.13m增加至0.45±0.17m,步速由0.36±0.19m/s增加至0.47±0.14m/s;首次着地时踝关节的跖屈角度明显减少,由-11.98±8.43°减至-3.94±4.31°;髋关节站立相最大伸展角度由-7.41±10.06°增加至-14.10±10.60°;迈步相踝关节最大背屈角度明显提高,平均由-8.19±9.63°增至-4.25±3.71°;矢状面踝关节角度活动范围明显降低,平均由14.44±9.99°减至9.40±5.77°。结论:配戴踝足矫形器可以明显减轻脑瘫患儿异常步态模式的程度。

Objective： To study the effect of ankle foot orthoses on improving the abnomal gait pattern in spastic diplegia cerebral palsy children. Method： Gait analysis was performed in 16 spastic diplegia cerebral palsy children on the same day with barefoot and ankle-foot orthoses. Result：The use of ankle-fbot orthoses produced a statistically significant increase in stride length and speed. In braces, ankle dorsiflexion at initial-contact, plantarflexion at toe-off, the Max. extension in stand phase, Max. flexion in swing phase and total excursion on sagittal plane were reduced, while hip extension at toe-off and the Max. extension in stand phase were increased. Conclusion： The ankle-foot orthoses is effective to improve the abnormal gait pattern.
