9.1.2 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.
9.1.3 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 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.
9.1.4 Sitting down
The resistance in the prosthetic knee joint while sitting down ensures evenly
bending into the sitting position.
1) Place both feet side by side at the same level.
2) While sitting down, distribute weight evenly between both legs and use
armrests, if available.
3) Move the buttocks in the direction of the backrest and lean the upper body
forward.
INFORMATION: Resistance while sitting down can be changed with the
Cockpit app or the remote control via the parameter "Resistance" (see
Page 77)
.
9.1.5 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.
If the patient is in a sitting position for more than two seconds (i.e. the thigh is
close to horizontal and there is no load on the leg), the knee joint switches the
resistance to a minimum in the extension direction.
A sitting function can be enabled by the prosthetist. For more information
about the sitting function, see the following section.
