The Step-On AFOs incorporate unilateral or bilateral spring-loaded hinges. Those allow a range of movement (ROM) between 22° dorsiflexion and 11° plantarflexion. This ROM enables improved initial heel contact and foot clearance during swing phase, better step clearance when climbing stairs and the ability to walk up /down hill, or with a small heel, without affecting the tibial alignment. It also allows the knee to fl ex past 90° while sitting, which promotes independence in sitting to standing for patient.
