研究表明，50% 的脑瘫儿童需要佩戴踝足矫形器。使用踝足矫形器的目的之一是帮助行走。这项研究检查了踝足矫形器对脑瘫儿童行走时的能量恢复和机械功的影响。 21 名患有痉挛性截瘫的儿童使用或不使用规定的双侧踝足矫形器行走。其中 10 名受试者佩戴铰接式（铰接）矫形器，11 名受试者佩戴实心矫形器。收集三维运动学数据，并将组间和组内重复测量方差分析应用于相关测量。两组的结果相似。步幅、能量恢复、势能和动能变化都有所增加。行走所进行的机械功或标准化质心垂直偏移没有变化。不幸的是，能量回收的增加并没有改变外部功，因为它被质心势能和动能变化的增加所抵消。测量的工作量存在很大差异，佩戴矫形器时，个体受试者的工作量会大幅增加和减少。这些结果表明，目前的踝足矫形器可以减少行走的工作量，但对于许多脑瘫儿童来说却无法做到这一点。这项研究表明，通过测量步行过程中的机械功可以帮助制定踝足矫形器处方。
Studies suggest that 50% of children with cerebral palsy are prescribed ankle foot orthoses. One of the aims of ankle foot orthosis use is to aid in walking. This research examined the effects that ankle foot orthoses have on the energy recovery and the mechanical work performed by children with cerebral palsy during walking. Twenty-one children with spastic diplegia walked with and without their prescribed bilateral ankle foot orthoses. Ten of the subjects wore articulated (hinged) orthoses and 11 subjects wore solid orthoses. Three dimensional kinematic data were collected and between and within group repeated measures ANOVAs were applied to the dependent measures. The results were similar for both groups. There was an increase in stride length, energy recovery, and potential energy and the kinetic energy variation. There was no change in the mechanical work performed to walk or the normalized center of mass vertical excursion. Unfortunately, the increase in energy recovery did not alter the external work, as it was offset by increased variation in the potential and kinetic energies of the center of mass. There was a great deal of variability in the measured work, with both large increases and decreases in the work of individual subjects when wearing orthoses. These results suggest that current ankle foot orthoses can reduce the work to walk, but do not do so for many children with cerebral palsy. This research suggests that ankle foot orthosis prescription could be aided by measuring the mechanical work during walking.
