9.1 Movement patterns in basic mode (mode 1)

9.1.1 Standing

Knee control through high hydraulic resistance and static alignment.
A stance function can be enabled using the adjustment software. Please see the following
section for further information on the stance function.

9.1.1.1 Stance function

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 86).
The stance function (standing mode) is a functional supplement to the basic mode (mode 1). This function makes it
easier, for example, to stand on an inclined surface for a longer time. The joint is fixed in the flexion direction.
This function must be enabled in the adjustment software. Once the function is enabled, you can also choose
between an intuitive and a conscious lock.
Intuitive locking of the joint
The intuitive stance function 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 surfaces. The knee joint is
always locked in the flexion direction when the prosthetic leg is not fully extended, under some amount of load and
at rest. Upon forward or backward rollover or extension, the level of resistance is immediately reduced to stance
phase resistance again.
The knee joint is not locked when the above conditions are met and a sitting position is assumed (for example while
driving).
Deliberate locking of the joint
1) Assume the desired knee angle.
2) Do not remove the entire load from the prosthesis.
3) Do not change the knee angle for a brief period (1/8 second). This time period prevents unintentional activation
of the standing function.
→ The blocked joint can now be fully loaded in the flexion direction.
Deliberate unlocking of the joint
► By deliberately extending or unloading the knee joint, is it unlocked again.

9.1.2 Walking

Initial attempts at walking with the prosthesis always require the instruction of trained, quali­
fied personnel.
The hydraulics stabilise the knee joint in the stance phase and release the knee joint in the
swing phase so that the leg can swing forward freely.
Switching to the swing phase requires that the prosthesis roll over to the front out of the
stride position.
