8.1.3 Sitting down

The prosthesis makes it possible to sit down without unlocking it manually. The adjustable flexion resistance of the
hydraulic unit provides support while sitting down.
We recommend that the user supports themselves with their hands while sitting down, e.g.:
• Support on the armrests of the chair
• Support on the handles of a walker
• Use of forearm crutches
• Use of a cane
1) Stand 5 to 10 cm in front of the edge of the chair.
2) Place both feet side by side at the same level.
3) While sitting down, distribute weight evenly on both legs and push the pelvis in the dir­

8.1.4 Sitting

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 direc­
tion.
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 90), the resistance in the flexion direction is reduced as well.

8.1.5 Standing up

Notwithstanding low damping while sitting, the prosthesis supports standing up.
Damping 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 direction. This function makes it possible to
stand up with pauses in between. The joint fully supports weight during these pauses. If standing up is aborted,
the "sitting down" function is activated again.
The joint is locked after fully 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 over feet.

8.1.6 Walking down stairs

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.

While standing up, the edge of the chair should not yet touch the hollow of the knee nor
press against the lower leg.
ection of the backrest.
This causes the weight to shift to the heel and the prosthesis to tilt backward, which
makes the knee joint switch to the "sitting resistance". Support is therefore provided
while sitting down.
