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

Use
Activity mode B+ (semi-locked mode with stance phase flexion)
The knee joint is locked starting at stance phase flexion of up to 10°.
INFORMATION:The joint responds to a sitting movement by switching to high flexion
resistance.

8.2.2 Walking

Initial attempts at walking with the prosthesis always require the instruction of trained, quali­
fied personnel.
The hydraulics stabilise the knee joint 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.
If desired, stance phase flexion of up to 10° can be permitted for this mode in the adjustment
software (setting only available in activity mode B).

8.2.3 Sitting down

The prosthesis makes it possible to sit down without unlocking it manually. The adjustable flexion resistance of the
hydraulic unit provides support while sitting down.
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) Stand 5 to 10 cm in front of the edge of the chair.
2) Place both feet side by side at the same level.
3) While sitting down, distribute weight evenly on both legs and push the pelvis in the dir­

8.2.4 Sitting

In a sitting position, i.e. when the thigh is close to a horizontal position and there is no load
on the leg, the knee joint switches to low resistance in both the flexion and extension direc­
tions.
If an adequate load was not placed on the prosthesis while sitting down, the leg remains
extended during this process. Due to the nearly horizontal position of the lower leg, the flex­
ion resistance is reduced automatically and the lower leg drops down on its own.

8.2.5 Standing up

The prosthesis supports standing up despite the low flexion resistance while sitting.
The resistance is increased after rising from the seat. From an angle of approx. 45°, the knee joint identifies a
"standing up process" which results in what is called "pre-locking" in the flexion direction. This function makes it
possible to stand up with pauses in between. The joint fully supports weight during these pauses. If the process of
standing up is discontinued, the "sitting down" function is activated again.
The joint is locked after fully standing up.

While standing up, the edge of the chair should not yet touch the hollow of the knee nor
press against the lower leg.
ection of the backrest.
This causes the weight to shift to the heel and the prosthesis to tilt backward, which
makes the knee joint switch to the "sitting resistance". Support is therefore provided
while sitting down.
