Three point fixation to stabilise joints using a rigid orthosis is relatively simple. When movement is required in a single plane, a hinge can be incorporated preventing superfluous movement and consequent loss of stability and function. Alternatively the Reciprocating Gait Orthosis (RGO) which utilises a system of Bowden cables with a HKAFO to provide reciprocal flexion and extension forces at the hip joint may be used. Free standing is achieved in the RGO by trunk and arm movements, the cable tension effectively "locking" the hips in neutral. Force transfer through the cables also produces reciprocal gait. The upper limbs acting through external supports provide the initiating force, producing truncal extension and subsequent hip extension of the stance leg. The resulting flexion of the swing leg produces a forward step. Currently 40 patients have been fitted with the orthosis in Salford, of whom 22 are Spina Bifida patients (aged 3-34 years). Most have Thoraco-lumbar or upper Lumbar lesions. The device has performed well with 1 episode of "knee clash" and 3 patients have had structural failures. Functional walking has been achieved with the orthosis.
使用刚性矫形器进行三点固定以稳定关节相对简单。当需要在单一平面内运动时，可加入一个铰链以防止多余的运动以及随之而来的稳定性和功能丧失。或者，也可以使用往复式步态矫形器（RGO），它利用鲍登缆线系统与髋-膝-踝足矫形器（HKAFO）在髋关节处提供往复屈伸力。在RGO中，通过躯干和手臂运动实现独立站立，缆线张力有效地将髋关节“锁定”在中立位。通过缆线的力传递也产生往复步态。上肢通过外部支撑施加力量提供起始力，使站立腿的躯干伸展并随后使髋关节伸展。摆动腿的随之屈曲产生向前一步。目前在索尔福德已有40名患者装配了这种矫形器，其中22名是脊柱裂患者（年龄在3至34岁之间）。大多数患者有胸腰段或上腰段病变。该装置表现良好，出现过1次“膝盖碰撞”情况，3名患者出现结构故障。使用该矫形器已实现功能性行走。
