8 Use
8.1 Movement pattern in activity mode A (locked mode)
8.1.1 Standing
8.1.2 Walking
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

The knee joint is locked in the flexion direction. Therefore, proceed as you
would with a rigid knee joint.
INFORMATION: In response to a sitting movement, the joint switches to
high flexion resistance.
Initial attempts at walking with the prosthesis always require the instruction of
trained, qualified personnel.
The knee joint is locked in the flexion direction. Therefore, proceed as you
would with a rigid knee joint.
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.
