This study compared the differences in energy efficiency (energy cost) in children with myelomeningocele ambulating with either reciprocating gait orthoses (RGOs) or hip-knee-ankle-foot orthoses (HKAFOs). There were 15 children who ambulated with RGOs and 11 children braced and ambulating in HKAFOs. Velocity was measured in m/s, energy consumption was measured in mL/kg/min, and energy cost (energy consumption/velocity) was measured in mL/kg/m. Children in HKAFOs had a significantly higher energy consumption rate than children in RGOs. However, children who swing through in a HKAFO have a significantly faster velocity than children who ambulate with the RGO using a reciprocating pattern. The increased energy cost in the RGO group is influenced by their slower velocity, just as the decreased energy cost in the HKAFO group is influenced by their increased velocity. Therefore it appears that children in HKAFOs are more energy efficient than children in RGOs.
本研究比较了患有脊髓脊膜膨出的儿童使用往复式步态矫形器（RGO）或髋-膝-踝-足矫形器（HKAFO）行走时的能量效率（能量消耗）差异。有15名儿童使用RGO行走，11名儿童佩戴HKAFO并行走。速度以米/秒为单位测量，能量消耗以毫升/千克/分钟为单位测量，能量成本（能量消耗/速度）以毫升/千克/米为单位测量。佩戴HKAFO的儿童的能量消耗率明显高于使用RGO的儿童。然而，使用HKAFO摆动通过的儿童的速度明显快于使用往复式模式的RGO行走的儿童。RGO组能量成本的增加受到其较慢速度的影响，正如HKAFO组能量成本的降低受到其速度增加的影响一样。因此，似乎佩戴HKAFO的儿童比使用RGO的儿童更具能量效率。
