8.3 Movement pattern in activity mode C (yielding mode)

8.3.1 Standing

Flexion resistance is generally high while standing. The intuitive stance function automatic­
ally recognises any situation that puts strain on the prosthesis in the flexion direction but
where flexion is not permitted. Examples of this include standing on uneven or sloping sur­
faces.
The knee joint is always locked in the flexion direction when the prosthetic leg is not fully
extended, is under some amount of load and is at rest. When the load is taken off the leg or
upon forward or backward rollover, the level of resistance is immediately reduced to stance
phase resistance again.
INFORMATION
The intuitive stance function can be deactivated in the adjustment software for training purposes (e.g. walking
down stairs). The stance function should be reactivated once therapy exercises have been completed. The patient
must be able to master the stairs with the stance function switched on as well.

8.3.2 Walking

Initial attempts at walking with the prosthesis always require the instruction of trained, quali­
fied personnel.
The hydraulics stabilise the knee joint with high flexion resistance in the stance phase and
release the knee joint in the swing phase so that the leg can swing forward freely.
In order to safely switch to the swing phase, the prosthesis has to be partially unloaded from
the lunge position with a simultaneous forward movement.

8.3.3 Sitting down

The prosthesis provides high flexion resistance while sitting down. This ensures that the knees bend evenly,
thereby supporting the contralateral side.
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) Place both feet side by side at the same level.
2) While sitting down, weight should be distributed evenly between both legs and the arm
3) Move the buttocks in the direction of the back support and lean the upper body forward.

8.3.4 Sitting

In a sitting position, i.e. when the thigh is close to a horizontal position and there is no load
on the leg, the knee joint switches to low resistance in both the flexion and extension direc­
tions.
If an adequate load was not placed on the prosthesis while sitting down, the leg remains
extended during this process. Due to the nearly horizontal position of the lower leg, the flex­
ion resistance is reduced automatically and the lower leg drops down on its own.

supports used where applicable.
This causes the weight to shift to the heel, making the knee joint switch to the "sitting
resistance". Support is therefore provided while sitting down.
