8.2.5 Walking up stairs
When the lower leg reaches a vertical position, the prosthesis prevents tipping
forward in order to stabilise. Walking up stairs step-over-step is only possible
if certain physical conditions are met. This function must be practised and
executed consciously.
1) Hold the handrail with one hand.
2) Place the foot of the sound leg on the first step.
3) Pull up the leg with the prosthetic foot and position it on the step with the

8.2.6 Walking down stairs

This function must be practised and executed consciously. Only by properly
stepping down with the sole can the system switch correctly and permit con­
trolled rollover. The motion must be carried out in a continuous pattern in
order to allow the motion to proceed in a fluid manner.
A stair function can be activated by using the adjustment software. See the fol­
lowing section for further information regarding the stair function.
1) Hold on to the handrail with one hand.
2) Position the leg with the prosthetic foot on the step so that as much of the

4) Place the leg with the prosthetic foot on one step beyond the next step.
5) At the end of the stairs, take a bigger step when transitioning to level

8.2.6.1 Stair function

The stair function increases the rollover angle when walking down stairs. This function should be
switched on when walking down stairs step-over-step. If walking down stairs step-over-step is not
required, this function can be switched off. Further information on switching on/off see Page 61.

8.2.7 Walking down a ramp

With the first step, the foot is already adjusted to the inclination of the ramp,
making it possible for the heel to strike while lowering the tip of the foot so the
entire sole of the foot is on the surface during the rollover. Lowering the tip of
the foot is restricted for walking with a prosthetic knee joint.
After the prosthetic foot is put down on the ramp, one should not use the knee
to work against it, but should allow movement in the knee joint during heel
strike (yielding). The prosthesis movement is recognised as walking as a res­

INFORMATION: Rolling the foot over the edge of the stair is not
necessary.
While doing so, check whether the knee joint and prosthetic foot will allow
this motion.

down the stairs to normal walking phase.
