Reciprocating Gait Orthosis
Also written as: RGO — Reciprocating Gait Orthosis
A bilateral hip–knee–ankle–foot orthosis that uses a cable or linkage system to couple hip flexion on one side with hip extension on the other, enabling step-over-step ambulation in patients with lower-limb paralysis.
Full Definition
The reciprocating gait orthosis (RGO) is an advanced bilateral HKAFO variant designed primarily for individuals with thoracic-level spinal cord injuries or spina bifida. Its defining feature is a mechanical coupling mechanism — typically a Bowden cable or isocentric bar — that translates weight shift into controlled, alternating hip movement. This allows a functional, though effortful, gait pattern that would be impossible with standard bilateral HKAFOs. In orthotic documentation, 'RGO' should be spelled out on first use; subsequent references may use the acronym. Editors should not confuse it with a standard HKAFO, which lacks the reciprocal coupling.
Usage
Usage note: Spell out on first use in any document. Distinguish carefully from 'hip guidance orthosis,' which is a related but distinct design.
In Context
- "The physiatrist's report referenced a reciprocating gait orthosis (RGO) rather than a standard bilateral KAFO, and the editor confirmed the distinction before finalising the text." — Clinical case report editing
- "RGO training sessions were documented as separate billable encounters in the rehabilitation notes." — Inpatient rehabilitation discharge summary
