9.2.3 Sitting down/sitting
Sitting down
1) Place both feet side by side at the same level.
2) While sitting down, distribute weight evenly between both legs and use armrests, if avail­
able.
3) Move the buttocks in the direction of the backrest and lean the upper body forward.
Sitting
The relief function can be used when sitting; the tip of the foot lowers to reach a more natur­
al foot position. (see page 66).
9.2.4 Standing up
1) Place the feet at the same level. Make sure the foot is positioned perpendicularly under
the knee or shifted further forward, and that weight is distributed evenly over the feet.
INFORMATION: The ankle joint may lock if the prosthetic foot is set further back
than at a perpendicular angle under the knee.
2) Lean the upper body forward.
3) Put the hands on armrests, if available.
4) Stand up with support from the hands, while keeping weight evenly distributed on the
feet.
9.2.5 Walking up stairs
The position is stabilised through high dorsiflexion damping with vertical lower leg. Walking
up stairs step-over-step is possible, depending upon the type of fitting.
Always hold on to the handrail with one hand when walking up steps.
9.2.6 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 controlled rollover. The motion must
be carried out in a continuous pattern in order to allow the motion to proceed in a fluid man­
ner.
A stair function can be activated by using the adjustment software. See the following 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 sole of the foot
as possible is on the step.
INFORMATION: Rolling the foot over the edge of the stair is not necessary.
3) Place the contralateral side onto the next step.
While doing so, check whether the knee joint and prosthetic foot will allow this motion.
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 ground, so that the
prosthetic foot switches over correctly from walking down the stairs to normal walking
phase.
9.2.6.1 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 69.
