Walking; Sitting Down; Sitting; Standing Up - Otto Bock Kenevo 3C60 Instructions For Use Manual

leg is not fully extended, is under some amount of load and is at rest. When the load is taken off
the leg or forward or backward rollover occurs, the level of resistance is immediately reduced to
stance phase resistance again.

8.3.2 Walking

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

8.3.4 Sitting

8.3.5 Standing up

Notwithstanding low damping while sitting, the prosthesis supports standing up.
Damping is increased after rising from the seat.
After standing up entirely, high damping (corresponding to the value of the "stance phase damp­
ing" parameter) is set automatically.
INFORMATION
If the intuitive stance function was deactivated in the adjustment software, there is no support
while standing up.
Initial attempts at walking with the prosthesis always require the instruction of
trained, qualified 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.
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 supports used where applicable.
3) Move the buttocks in the direction of the back support and lean the upper
body forward.
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.
If the user is in a sitting position, i.e. the thigh is close to horizontal and there
is no load on the leg, the knee joint switches to a low resistance in both the
flexion and extension direction.
If the load on the prosthesis was not sufficient while sitting down, the leg is
extended during this process. Due to the nearly horizontal position of the lower
leg, the flexion resistance is reduced automatically and the lower leg lowers on
its own.
If the sitting function is enabled in the adjustment software and activated via
the Cockpit app (see page 79), the resistance in the flexion direction is
reduced as well.
