Three thoracic level spina bifida patients were evaluated in a gait laboratory. The patients first were asked to walk with a swing-through gait pattern using conventional hip-knee-ankle-foot orthosis and then with a reciprocating gait pattern using the reciprocating gait orthosis (RGO). The reciprocating gait was modestly more efficient than the swing-through gait pattern. The average speed of free walking was 11.4 meters per minute with the swing-through pattern and 16.2 meters per minute with the reciprocating pattern. The stride length was 0.31 meters and 0.54 meters with the swing-through and reciprocating patterns respectively. The RGO needs further modifications to improve the walking ability of spina bifida patients. The hip joints permit only flexion and extension and no rotational movement. The lack of internal and external rotation inhibits hip movement, reduces stride length, reduces the speed of walking and causes the cables to bind and eventually break. With design changes, future bracing systems will permit improved walking in the high level spina bifida patients.
三名胸段脊柱裂患者在步态实验室接受了评估。首先要求患者使用传统的髋-膝-踝-足矫形器以摆动通过步态模式行走，然后使用往复式步态矫形器（RGO）以往复步态模式行走。往复步态比摆动通过步态模式略高效。自由行走时，摆动通过模式的平均速度为每分钟11.4米，往复模式为每分钟16.2米。摆动通过模式和往复模式的步幅分别为0.31米和0.54米。RGO需要进一步改进以提高脊柱裂患者的行走能力。髋关节仅允许屈伸，不允许旋转运动。缺乏内旋和外旋会抑制髋关节运动，缩短步幅，降低行走速度，并导致缆线捆绑并最终断裂。通过设计改进，未来的支撑系统将使高位脊柱裂患者的行走能力得到改善。
