You should know this if you passed your ABC exam. Where are you going
with this?

By tweeked you mean what? Do you mean that you have tweeked a Prefab PLS
and now it's a custom molded floor reaction AFO?
This really doesn't answer the question but you need to hear it.
I don't think you know what a ground reaction AFO is. If you did know,
then you wouldn't suggest that a PLS could do the same job as you have
done in part 2 of your question.

As opposed to what? A strap? A ground reaction AFO transmits force to
the knee and anterior proximal tibia. In order to distribute the force
evenly and in the correct places the anterior portion needs to be custom
molded and rigid.
