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.
INFORMATION
For covering longer distances, the prosthetist can configure a "Running" MyMode (see
Page 89).
9.1.4 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
use the arm supports 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 84)
.
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.
9.1.5.1 Sitting function
INFORMATION
To use this function, it needs to be enabled in the adjustment software. It also has to be activ
ated using the Cockpit app (see Page 84).
In the sitting position, the resistance in the flexion direction is reduced in addition to the reduction
of resistance in the extension direction. This makes it possible to swing the prosthetic leg freely.
