8.2.4 Sitting
In a sitting position, i.e. when the thigh is close to horizontal and there is no load on the leg,
the knee joint switches to low resistance in both the flexion and extension directions.
If the load on the prosthesis is not adequate, the leg remains extended while sitting down.
Due to the nearly horizontal position of the lower leg, damping is reduced automatically and
the lower leg drops down on its own.
8.2.5 Standing up
Notwithstanding low damping while sitting, the prosthesis supports standing up.
Damping is increased after rising from the seat. From an angle of approx. 45°, the knee joint identifies a "standing
up process" which results in what is called "pre-locking" in the flexion direction. This function makes it possible to
stand up with pauses in between. The joint fully supports weight during these pauses. If standing up is aborted,
the "sitting down" function is activated again.
The joint is locked after fully 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 over feet.
8.2.6 Walking down stairs
The knee joint is locked in the flexion direction.
1) Hold the handrail with one hand.
2) Place the foot of the prosthesis leg on the first step.
3) Bring up the contralateral leg.
INFORMATION: Walking down stairs step-over-step is not possible in this activity
mode.
8.2.7 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 contralateral leg on the first step.
3) Bring up the leg with the prosthesis.
