Walking; Running Short Distances ("Walk-To-Run" Function); Sitting Down - Otto Bock Genium X3 Instructions For Use Manual

Intuitive locking of the joint
The intuitive stance function 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, under some amount of load and
at rest. Upon forward or backward rollover or extension, the level of resistance is immediately reduced to stance
phase resistance again.
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 unintentional activation
of the stance function while walking.
→ The blocked joint can now be loaded in the flexion direction.
Deliberate unlocking of the joint
► By deliberately extending or unloading the knee joint, is it unlocked again.

9.1.2 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.
Switching to the swing phase requires that the prosthesis roll over to the front out of the
stride position.

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

For covering short distances quickly, the knee joint detects a transition from walking to run­
ning in basic mode and automatically changes the following settings:
•
•
The requirements to automatically switch to the running motion are fast forward 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.
INFORMATION
For covering longer distances, a "Running" MyMode can be configured using the adjustment software (see
page 45).

9.1.4 Sitting down

The resistance in the prosthetic knee joint while sitting down ensures even bending into the
sitting position.
The adjustment software can be used to configure whether the sitting process is to be sup­
ported 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
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 41).
