In a Metal AFO, what can the ankle joint be configured to?

Explanation:
A metal AFO uses an articulated ankle joint whose motion can be controlled. The ankle joint can be locked for a rigid ankle or set to allow only limited anterior/posterior movement (dorsiflexion/plantarflexion). This setup provides stability when needed—preventing things like foot slap or excessive tibial progression—while still permitting limited motion to assist a safer, more efficient gait. Unrestricted free motion in all directions isn’t typical because we want to manage motion in the sagittal plane to maintain alignment and control.
