Which orthosis is listed for high lumbar L1-L2?

• A. RGO
• B. HKAFO
• C. AFO
• D. Wrist brace

Answer: (A)

For high lumbar levels like L1–L2, the goal is to stabilize the hips and knees to enable functional ambulation, since control at the knee and hip is essential for standing and initiating steps. The Reciprocating Gait Orthosis is designed specifically for this level of function. It provides hip and knee stabilization and uses a cable system that synchronizes movement between the legs, allowing a more natural, energy-efficient gait with assistive devices. An ankle-foot orthosis targets only the foot and ankle, which isn’t enough to support knee or hip control at this level. A hip-knee-ankle-foot orthosis offers substantial stabilization but lacks the reciprocal mechanism that makes gait easier and more feasible for L1–L2 lesions. The wrist brace is unrelated to spinal-level gait the way these leg orthoses are. So, the Reciprocating Gait Orthosis best fits high lumbar L1–L2.
