5. Once you are in sitting position, you can lift the prosthetic foot from the ground and you will notice that the
prosthetic knee will unlock and move freely.
EXERCISE MODE
1. Sit down.
2. Fully extend the prosthetic knee out.
3. Pull under the toe of the prosthetic foot for approx. 5 seconds while keeping the prosthetic knee extended out.
4. The knee will indicate that it is in exercise mode by giving one beep and a vibration.
5. To exit the exercise mode, turn the knee off. When you turn it back on the knee will be in normal mode. This
prevents unwanted exercise mode exit during use.
Always use the banister or handrail when ascending or descending ramps and stairs.
DESCENDING STAIRS OR RAMPS (Figure 13)
1. Take the first stride with the prosthesis and transfer your weight onto the prosthesis. Feel how the prosthetic
knee bends and supports you while you move the other foot to the next step. It is recommended to lean
backwards slightly as this facilitates knee bending and, in case of loss of balance, prevents you from falling
forward.
2. Continue descending the stairs or ramp at your normal pace. The behavior of the prosthetic knee will adjust
automatically, supporting your descent naturally.
3. It is recommended to place half of the foot onto the lower step to ensure consistent support when walking
down.
4. If a problem occurs, stop walking, hold the prosthetic foot in contact with the ground for approx. 3 seconds
then resume descending the stairs or ramp, starting with the prosthesis.
Always use the banister or handrail when ascending or descending ramps and stairs.
KNEELING
1. Allow the prosthetic knee to reach the "standing state"
2. Place and maintain load onto the prosthesis.
3. Put your sound leg in front of the prosthesis.
4. Force the prosthesis into flexion by flexing your hip slightly. Feel how the prosthetic knee supports you while
kneeling down.
ASCENDING RAMPS
1. When ascending ramps, simply walk at your normal pace.
2. The same knee function is used while ascending ramps as when walking on a level surface.
3. If a problem occurs, stop walking, hold the prosthetic foot in contact with the ground for approx. 3 seconds
than resume walking.
Always use the banister or handrail when ascending or descending ramps and stairs.
ASCENDING STAIRS (Figure 14)
1. Come to a complete stop before the first step of the stairs.
2. Allow the prosthetic knee to reach the
“standing state”
. Keep the prosthesis still and avoid little steps or forward
leaning on the prosthesis.
3. Gently lift the prosthesis off the ground by bending your hip. The knee will unlock and progress to slightly bent
position. Place your foot onto the first step and transfer your weight onto the prosthesis. Now extend your hip
and feel how the prosthetic knee lifts you and make sure to keep your balance.
4. Continue ascending the stairs at your normal pace. The behaviour of the prosthetic knee will adjust
automatically, assisting your ascent naturally.
5. In order to avoid falls, make sure you verify your prosthetic foot placement on each step. At least half of the foot
should be positioned onto the step to secure support when loading the prosthesis.
6. If a problem occurs, stop walking, hold the prosthetic foot in contact with the ground for approx. 3 seconds
then resume ascending the stairs, starting with the prosthesis.
