When to use PF stop versus solid AFO?

[Jennifer Warrington]

Confused on using solid AFO vs. Plantarflexion stop.

[Helen Carey]

Think about function and when DF is important. The main difference between a solid AFO and a hinged/articulating AFO is DF motion. If a child is ambulatory and they need to squat, descend stairs, etc, then an orthosis that allows for DF motion will likely be the most functional. If a child uses AFOs mainly for positioning (in a w/c or during stand-pivot transfers), then a solid AFO will likely meet their needs.

What about a posterior leaf AFO. Does it also help to assist with DF?

[Helen Carey]

Yes, a posterior leaf AFO is designed to assist with DF. However, it is not custom molded/fabricated. As a result, it doesn’t do well in the presence of spasticity or significant hypotonia (needing substantial support to block PF and/or support DF). The most common use of a posterior leaf AFO in peds is for neuropathy and anterior tibialis paralysis (or severe weakness), but relatively intact function of the rest of the lower limb.
