AFO dorsi-assist alternatives?

AFO dorsi-assist alternatives?

Practitioners,

Problem: Active adult Cerebral Palsy patient in dorsi-assist AFO's in which
tone, for the most part, overrides the springs in the standard Klenzak
joints. Installing pins is not an option, as it disrupts his gait pattern
too much, and inhibits him from driving (using the accelerator). I have used
elastic webbing and Gaffney flexors to help with this problem, but longevity
is short. Is there any other durable, strong dorsi-assist alternative
available? I've heard of using GII KO knee joint bands but have yet to
explore: Has anyone had experience with these?

I will eventually be making a new set of AFO's utilizing Oregon principles
and design. This will hopefully help with the tone. However, for now, I
need to make the best of his existing 3 y/o hybrid metal/polypro AFO's by
attempting to increase the dorsi-assist. Suggestions?

Thanks in advance.
