Standing Up; Walking Up Stairs Step-Over-Step; Overcoming Obstacles - Otto Bock Genium X3 3B5-3 Instructions For Use Manual

Use
In the sitting position, the resistance in the flexion direction is reduced in addition to the reduction of resistance in
the extension direction. This makes it possible to swing the prosthetic leg freely.

9.1.6 Standing up

Flexion resistance is increased steadily while standing up.
1) Place the feet at the same level.
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 feet.

9.1.7 Walking up stairs step-over-step

INFORMATION
To use this function, it needs to be enabled in the adjustment software. It also has to be activated using the Cock­
pit app (see page 92).
Although the knee joint is passive, which means it cannot actively initiate movements, negoti­
ating stairs step-over-step is possible.
This function must be practised and executed consciously.
1) Lift the extended prosthesis off the floor.
2) Immediately after lifting the extended leg off the floor, extend the hip briefly and then
3) When sufficient knee flexion has been achieved, the knee joint increases extension res­
4) Set the foot onto the next step.
5) Support yourself with your hand on the contralateral side. A smooth wall will also work.
6) Bring the knee into extended position. When the knee joint is fully extended, the initial
7) You can climb the next step or continue walking normally.

abruptly flex it. This requires a sufficiently secure hold in the socket and a certain level of
residual limb strength.
→ This whip motion flexes the knee, because the knee joint automatically recognises
the movement and sets the flexion resistance to minimum.
INFORMATION: Take note of people behind you before executing the whip
motion.
istance so that there is enough time to position the foot on the next step before the knee
joint is extended again.
The support area for the foot on the step must be large enough that the heel does not
extend back too far over the edge. With too little support area, the lower leg would
extend too early and position the leg too far backwards. In this phase, the knee joint has
already set the flexion resistance to maximum (blocked). The knee joint can no longer be
flexed but only extended. This ensures that the leg does not buckle if the hip strength is
not sufficient for the extending motion.
This lateral support is intended to prevent the residual limb from twisting in the socket.
Twisting can lead to unpleasant surface tension between the skin and the socket. Lateral
support also improves balance.
