4. Select ‘Slow Power’ to fine-tune the powered push off at ‘Slow Power’.
5. To adjust powered push off on stairs and ramps, select ‘Fast Power’ and adjust
as needed. In stair ascent, instruct the user to lead with their non-affected side
on the first step. When stepping onto the Ankle, the user should land directly on
the toe with approximately 15
o
of flexion in the knee. The user should completely
transfer his/her weight to the affected side, using minimum assistance from rails,
in order to generate the required torque to invoke a reflex from the Ankle.
For optimal performance, power settings should be tuned to the lowest acceptable level
for the user.
NOTE FOR BILATERAL USERS
• Tune power on the non-dominant side before the dominant side.
• Ensure the patient feels stable while standing.
• All users must be trained to ascend and descend stairs. Failure to do so may result in
users being surprised by an unexpected powered reflex. Such a surprise may lead to a
fall causing serious injury or death.
• For stair descent, it is important to teach the user to place the foot in a manner such that
the forefoot does not make contact with the steps. This will ensure the Ankle will not
respond with a reflex while descending stairs.
• User may receive Toe Strike Power while walking backward on level ground.
If power settings are not optimized for all speeds, ramps and stairs, move to the
Advanced Tools tab.
