¶ Introduction
An ankle foot orthosis (AFO) is a biomechanical device that provides support to the foot and ankle, especially when walking. AFOs are prescribed for a variety of conditions; in the case of ALS, their primary function is to help provide sufficient toe clearance while walking.
An off-the-shelf ankle foot orthosis (AFO).
¶ Start using when…
Still able to walk independently for moderate distances, but there are some minor fatigue and balance issues; foot drop
¶ Types
AFOs are available in a number of different styles and can be either purchased off-the-shelf or custom-made.
Off-the-shelf AFOs often need minor adjustments, such as heating to reshape or adding small pads to alleviate pressure points.
Custom-made AFOs generally cost more than off-the-shelf options but provide a better fit.
¶ Further Considerations
Buying AFOs without a prescription from an occupational therapist or physiatrist is generally possible, however, higher-grade AFOs, including custom-made AFOs will generally require a prescription. Insurance companies will only cover AFOs that have been prescribed.
