Standing; Walking; Sitting Down - Ottobock Kenevo 3C60 Instrucciones De Uso

7.3.1 Standing

Flexion resistance is generally high while standing. The intuitive stance func­
tion 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 upon forward or backward rollover, the level of res­
istance is immediately reduced to stance phase resistance again.
INFORMATION
The intuitive stance function can be deactivated in the adjustment software by the O&P profes­
sional for training purposes (e.g. walking down stairs). The stance function should be reactiv­
ated once therapy exercises have been completed. The user must be able to master the stairs
with the stance function switched on as well.

7.3.2 Walking

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.

7.3.3 Sitting down

The prosthesis provides high flexion resistance while sitting down. This ensures that the knees
bend evenly, thereby supporting the contralateral side.
Hand support is recommended while sitting down, e.g.:
• Support on the armrests of the chair
• Support on the handles of a wheeled walking frame
• Use of forearm crutches
• Use of a cane
Sitting down
1) Place both feet side by side at the same level.
2) While sitting down, distribute weight evenly between both legs and use
3) Move the buttocks in the direction of the backrest and lean the upper body

armrests, if available.
forward.
This causes the weight to shift to the heel, making the knee joint switch to
"sitting damping". Support is therefore provided while sitting down.
