Walking; Running Short Distances ("Walk-To-Run" Function); Sitting Down; Sitting - Ottobock Genium-Bionic Prosthetic System 3B1 Gebrauchsanweisung

The knee joint is not locked when the above conditions are met and a sitting position is assumed
(for example while driving).
Deliberate locking of the joint
1) Assume the desired knee angle.
2) Do not remove the entire load from the prosthesis.
3) Do not change the knee angle for a brief period (1/8 second). This time period prevents unin­
tentional activation of the standing function.
→ The blocked joint can now be fully loaded in the flexion direction.
Deliberate unlocking of the joint
► By deliberately extending or unloading the knee joint, is it unlocked again.

8.1.2 Walking

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.

8.1.3 Running short distances ("walk-to-run" function)

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 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.

8.1.4 Sitting down

The resistance in the prosthetic knee joint while sitting down ensures evenly
bending into the sitting position.
The O&P professional can set either a constant resistance or a continuously
increasing resistance for sitting down.
1) Position both feet side by side at the same level.
2) While sitting down, distribute your weight evenly between both legs and
3) Move the buttocks in the direction of the back support and lean the upper
INFORMATION: Resistance while sitting down can be changed with the
Cockpit app via the parameter "Resistance" (see Page 85).

8.1.5 Sitting

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.
The swing phase angle is increased
Preflexion of 4° at heel strike (PreFlex) is reduced to 0°
