Handling, Functionality, Risks

8.3.1 Standing

Knee control through high hydraulic resistance and static alignment.
The orthosis has no locking function, so that slow bending is possible under flexion load. To restore the
stable standing position, place the leg back under the body and put weight on the heel.
Manually switch to LOM mode for extended standing.
INFORMATION: By adjusting the parameter 'Stance Function Timer [*20ms]' via C-Soft, high stance
phase damping is activated after the knee joint remains flexed (5° to 20°) for a period of time (STA
mode). This mode is deactivated by extending the knee joint.

8.3.2 Walking

Initial attempts at walking with the orthosis always require the instruction of trained, qualified person­
nel. 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.
To safely switch to the swing phase, the system requires special measurements and prerequisites. The
fundamental prerequisite is a sufficient forefoot load with simultaneous extension of the orthosis knee
joint. If this is not achieved, the leg cannot swing through.
INFORMATION: When walking on soft surfaces (forest floor), more force may be required to trigger
the swing phase.

8.3.3 Sitting Down

INFORMATION
If a mode with a high setting for the parameters 'Base Resistance' and/or 'Resistance Gain' such as "Extended
Stance" is configured as 2nd mode, switching to 1st mode must be performed before sitting down. Otherwise it
is not possible to bend the knee joint.
Orthosis damping while sitting down ensures that the knees bend evenly, thereby supporting the
sound side.
1) Position the feet side by side.
2) While sitting down, distribute your weight evenly between both legs and use the armrests where
applicable.
INFORMATION: Avoid supporting your weight on the armrests.
3) Move the buttocks in the direction of the backrest and lean the upper body forward.

8.3.4 Standing Up

INFORMATION
If the orthosis was switched to 'cycling' mode (2nd mode) for sitting, it must be switched to 1st more before
standing up. Otherwise secure standing with the orthosis is not assured.
1) Place the feet side by side.
2) Lean the upper body forward.
3) Put the hands on the armrests if applicable.
4) Stand up with support from the hands.
