Walking; Running Short Distances ("Walk-To-Run" Function); Sitting Down; Sitting - Otto Bock Genium 3B1-3 Instructions For Use Manual

Deliberate unlocking of the joint
► By deliberately extending or unloading the knee joint, is it unlocked again.
INFORMATION
Stance function with hip disarticulation amputation level
Due to personal abilities and experiences with prostheses, these users may encounter diffi­
culties with activating/deactivating the stance function. If these users want to stand with a flexed
and locked knee joint for extended periods of time, the O&P professional can configure a
MyMode that can be activated/deactivated using the Cockpit app.

INFORMATION
While sitting, the knee joint also switches to energy saving mode. This energy saving mode is
activated regardless of whether the sitting function is activated or not.
Initial attempts at walking with the prosthesis always require the instruction of
trained, qualified 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.
Switching to the swing phase requires that the prosthesis roll over to the front
out of the stride position.
For covering short distances quickly, the knee joint detects a transition from
walking to running in basic mode and automatically changes the following set­
tings:
• The swing phase angle is increased
• Preflexion of 4° at heel strike (PreFlex) is reduced to 0°
The requirements to automatically switch to the running motion are fast for­
ward movement of the prosthetic leg and high dynamic load on the knee joint.
When stopping from the running motion, the changed settings are set back to
the standard values.
The resistance in the prosthetic knee joint while sitting down ensures even
bending into the sitting position.
The O&P professional can use the adjustment software to configure whether
the sitting process is to be supported or not.
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.
INFORMATION: Resistance while sitting down can be changed with the
Cockpit app via the parameter "Resistance" (see page 31).
