踝足矫形器对脑瘫患儿异常步态的影响

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。

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

Objective:To study the effect of ankle foot orthoses on improving the abnormal 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-foot 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.
