8.7.2 Stance function
The stance function is a functional supplement to the basic mode. This function makes it easier for the patient to
stand on an inclined surface for a longer time. The joint is fixed in the flexion direction at a flexion angle between 5°
and 65°.
Enable the function by dragging the switch to the right
. When the function is activated, it can be turned on/off
using the Cockpit app.
Once the function is enabled (switch
dragged to the right), it is also possible to choose between an intuitive
and a manual lock. Subsequently changing the type of lock using the Cockpit app is not possible.
Intuitive locking of the joint
The intuitive stance function recognises any situation that puts strain on the orthosis in the flexion direction but
where flexion is not permitted. Examples of this include standing on uneven or sloping surfaces. The joint is always
locked in the flexion direction when the leg with the orthosis is not fully extended and is kept still for a brief
moment.
The joint is not locked when the above conditions are met and a sitting position is assumed.
Intuitive unlocking of the joint
►
Upon forward or backward rollover or extension, the flexion resistance is immediately switched from high to
stance phase resistance again.
Manual joint lock
►
Flex the joint between 5°
and 60°.
→
Now the blocked joint can be loaded in the flexion direction.
Releasing the manual joint lock
►
The Manual Stance function is automatically deactivated again by extending the knee or by repositioning the leg
(e.g. taking a step).
If this function has been deactivated by the patient, the information "(deactivated by patient)" appears next to the
switch
.
8.8 Optimisation while walking on the level
Parameter "Stance flexion resistance when walking on level surfaces"
If the parameter "
Stance flexion resistance
" for sitting down and negotiating
stairs and ramps is set correctly, but the patient sinks down in the stance phase
while walking on the level, the parameter "
Stance flexion resistance when
walking on level surfaces
" should be adjusted for the patient.
If elevated stance phase flexion resistance for walking on the level is not
wanted, the value of the parameter "
Stance flexion resistance when walking
on level surfaces
" has to be set equal to the value of the parameter "
Stance
flexion resistance
".
Parameter "Stance extension resistance"
This parameter can decide how quickly the knee joint returns to an extended
position again after stance phase flexion. The hardness of the stop can be influ
enced with this parameter.
Parameter "Swing flexion angle"
This parameter determines the target angle that represents the maximum flexion
of the knee in the swing phase. The angle is approximately 65° for a physiolo
gical gait, regardless of the walking speed.
