Stance Function; Walking; Sitting Down; Sitting - Otto Bock Kenevo 3C60 Instructions For Use Manual

Use

8.3.1.1 Stance function

INFORMATION
To use this function, it needs to be enabled in the adjustment app. It also has to be activated using the Cockpit
app (see page 90).
The intuitive stance automatically 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, 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

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

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 direc­
tion.
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 90), the resistance in the flexion direction is reduced as well.

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 damping" parameter) is
set automatically.
INFORMATION
If the intuitive stance function was deactivated in the adjustment software, there is no support while standing up.

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.
