Ankle-Foot Orthosis (AFO)

AFO Instructions

AFO (Graphite) Additional Instructions

This type of Orthosis can serve a variety of purposes, depending on clinical indications, but is primarily used when a condition commonly described as Foot Drop exists. When this Orthosis is indicated, it may also provide foot and ankle stability when ligaments or boney malalignment contribute to foot or ankle instability.

There are several types of AFOs, ranging from a rigid leaf-spring option to an articulated design, selecting from numerous types of ankle hinges that can control movement at the ankle and knee.

When used as a dropfoot splint, the Orthosis is often designed with pre-flexed hinges that will prevent the toes from dragging when the foot is off the ground. The brace may reduce energy expenditures, allowing for a more fluid gait pattern.

Some common pathologies that can result in Foot Drop are:

  • Diabetes
  • Peripheral Nerve Trauma
  • Multiple Sclerosis
  • cerebrovascular accident (CVA or stroke)
  • Poliomyelitis
  • Spinal Stenosis

There are numerous other pathologies whose symptoms may be improved by an AFO.

Under certain circumstances, the cost or a portion of the cost of this device may be covered for residents of Alberta by government funding.
