Don,
If this patient crouches more than 20 degrees, a floor reaction AFO
will help to hold him in as much an upright position as he can
achieve. This should help to prevent knee contractures from
increasing. I suspect that his ankles are also collapsing into
over pronation. If so, an attempt should also be made to control
this collapse.
I have followed a young man about the same age as your patient for
about 6 years. He was unable to tolerate complete control of his
over pronation nor full correction of his crouch(to the angle of his
contractures). His gait with his AFOs appeared very similar to his
gait without them. However, his AFOs allowed him to walk more
efficiently, using less energy and he didn't tire out as quickly with
them on.
