If the patient is in a sitting position for more than two seconds (i.e. the thigh is close to hori
zontal 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 using the adjustment software. For more information about
the sitting function, see the following section.
9.1.4.1 Sitting function
INFORMATION
To use this function, it needs to be enabled in the adjustment software. It also has to be activated using the Cock
pit app (see page 39).
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.
9.1.5 Standing up
Flexion resistance is increased steadily while standing up.
1) Place the feet at the same level.
2) Lean the upper body forward.
3) Put the hands on armrests, if available.
4) Stand up with support from the hands while keeping weight evenly distributed on feet.
9.1.6 Walking up stairs
Walking up stairs step-over-step is not possible.
1) Hold the handrail with one hand.
2) Place the foot of the sound leg on the first step.
Bring up the leg with the prosthesis.
