8.2.4 Sitting

8.2.5 Standing up

The prosthesis supports standing up despite the low flexion resistance while sitting.
The resistance is increased after rising from the seat. From an angle of approx. 45°, the knee joint
identifies a "standing up process" which results in what is called "pre-locking" in the flexion dir­
ection. This function makes it possible to stand up with pauses in between. The joint fully sup­
ports weight during these pauses. If the process of standing up is discontinued, the "sitting
down" function is activated again.
The joint is locked after fully standing up.

8.2.6 Walking down stairs

1) Stand 5 to 10 cm in front of the edge of the chair.
While standing up, the edge of the chair should not yet touch the hollow of
the knee nor press against the lower leg.
2) Place both feet side by side at the same level.
3) While sitting down, distribute weight evenly on both legs and push the pel­
vis in the direction of the backrest.
This causes the weight to shift to the heel and the prosthesis to tilt back­
ward, which makes the knee joint switch to the "sitting resistance". Sup­
port is therefore provided while sitting down.
If the user is in a sitting position, i.e. the thigh is close to horizontal and there
is no load on the leg, the knee joint switches to a low resistance in both the
flexion and extension direction.
If the load on the prosthesis was not sufficient while sitting down, the leg is
extended during this process. Due to the nearly horizontal position of the lower
leg, the flexion resistance is reduced automatically and the lower leg lowers on
its own.
If the sitting function is enabled in the adjustment software and activated via
the Cockpit app (see page 79), the resistance in the flexion direction is
reduced as well.
1) Place the feet at the same level.
2) Lean the upper body forward.
3) Place the hands on arm supports, if available.
4) Stand up with support from the hands while distributing weight evenly
between the feet.
The knee joint is locked in the flexion direction.
1) Hold the handrail with one hand.
2) Place the foot of the prosthetic leg on the first step.
3) Pull up the other leg.
INFORMATION: Walking down stairs step-over-step is not possible in
this activity mode.
