Tip!
Angular adjustment of the pyramid will impact the ratio of the 12 degrees of
movement. Plantarflexing at the pyramid will decrease the dorsiflexion range of motion
provided by the ankle. Dorsiflexing at the pyramid will increase the plantar flexion range
of motion.
Ensure that the range of dorsiflexion and plantarflexion motion is maintained during static
alignment. Check when flexion is properly accommodated that the system still has 2
⁰
dorsiflexion and 10
⁰
plantarflexion.
Dynamic Alignment
Once a stable static alignment is achieved, begin walking the patient in the parallel bars
to optimize alignment and function on level ground.

Using you
r patient’s feedback, adjust the
hydraulic valves carefully to balance the comfort
provided by the ankle damper and energy return provided by the foot module. (Higher
resistances will allow the carbon fiber to be loaded more, provided more energy return.
Lower resistances will allow more ankle motion and comfort while sitting and ambulating
on slopes and uneven terrain.)
