Knee control through high hydraulic resistance and static alignment.
A stance function can be enabled by the prosthetist. Please see the following
section for further information on the stance function.
8.1.1.1 Stance function
INFORMATION
To use this function, it must be enabled by the prosthetist. It also has to be activated using the
cockpit app or remote control (see Page 76).
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.
The standing function must be enabled by the prosthetist. In addition, the type of joint locking
(conscious/intuitive) has to be established by the prosthetist. Changing the locking type using the
Cockpit app or remote control is not possible.
Intuitive locking of the joint
The intuitive stance function recognises any situation that puts strain on the prosthesis in the flex
ion 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 unin
tentional 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.
