1 PreFlex
• Reduction of ground reaction forces for
improved shock absorption and extended knee
flexion that minimizes subsequent orthopaedic
problems
• Reduced stride initiation effort
• Easier and safer negotiation of slopes, inclines
and uneven terrain, as well as reduction of
compensatory movements
• Reduction of stride length asymmetry
• Significantly reduced cognitive effort and reduced need to control the prosthesis
OPG User Exercises
1 Watch the user walk with OPG turned on. Notice how
the PreFlex feature affects stance flexion while walking
on level ground and ascending a ramp. Turn OPG off
(program the stance and swing extension resistance with
it off) and have the user walk. Note the difference in
knee performance.
2 Place a weight around the prosthetic ankle or apply
a heavier shoe and notice the Adaptive Swing Phase
Control.

• Considerably • Quality of the swing phase is comparable to
increased safety

3 E valuate the Adaptive Yielding Control as the user sits
into a chair and as the user walks down a steep ramp.
4 Ask the user to walk down a shallow ramp without pull-
ing back on the knee. This will allow them to experience
the effects of Adaptive Yielding Control. The knee will flex
until it reaches a stop.
