We determined the effect of changes in abduction orthosis for clubfoot (bar width, dorsiflexion and abduction) on ankle dorsiflexion and foot abduction.
The study included 31 children with clubfoot. An adjustable Steenbeek foot abduction orthosis permitting variations of bar width [distance between anterior superior iliac spines, shoulders and 'standard'], dorsiflexion (0, 15 and 30°) and abduction (30, 45 and 70°) was used for measurements. Ankle dorsiflexion and foot abduction were measured with and without orthosis and compared using repeated measures analysis of variance (ANOVA).
Foot abduction was same as orthotic abduction in all configurations. A better ankle dorsiflexion was found with a shorter bar width, larger orthotic dorsiflexion and abduction. Contrarily, the arc increased with a wider bar. A 30° inbuilt orthotic dorsiflexion and 70° abduction produced better foot dynamics.
A foot abduction orthosis with modifications of shorter bar length, 30° dorsiflexion and 70° abduction may offer better soft tissue stretch and foot motion in clubfoot.
我们确定了先天性马蹄内翻足外展矫形器（杆宽度、背屈和外展）的变化对踝关节背屈和足部外展的影响。
该研究纳入了31名先天性马蹄内翻足患儿。使用一种可调节的斯廷贝克足部外展矫形器进行测量，该矫形器允许杆宽度[髂前上棘、肩部与“标准”之间的距离]、背屈（0°、15°和30°）和外展（30°、45°和70°）发生变化。在佩戴和不佩戴矫形器的情况下测量踝关节背屈和足部外展，并使用重复测量方差分析（ANOVA）进行比较。
在所有配置下，足部外展与矫形器外展相同。发现杆宽度较短、矫形器背屈和外展较大时，踝关节背屈更好。相反，杆越宽，弧度越大。内置30°矫形器背屈和70°外展可产生更好的足部动态。
一种杆长度较短、背屈30°和外展70°的足部外展矫形器可能会为先天性马蹄内翻足提供更好的软组织拉伸和足部运动。
