Standing; Walking; Sitting Down - Otto Bock C-Brace Gebrauchsanweisung

► Verify the changed damping characteristics after switching and observe the feedback from
the acoustic signal emitter.
Switch back to basic mode once the activities in the additional mode have been completed.
►
► Take the weight off the product and correct the switching, if required.

7.3.1 Standing

Knee control through high hydraulic resistance and static alignment.
The knee joint of the product 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 (see Page 60) for extended standing.
INFORMATION: By adjusting the parameter 'Stance function timer
[*20ms]' via the adjustment software, high stance phase damping is
activated after the knee joint remains flexed (5° to 20°) for a period of
time (STA mode (see Page 57)). This mode is deactivated by extending
the knee joint.

7.3.2 Walking

Initial attempts at walking with the product always require instruction from
trained, qualified personnel. 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 freely.
To safely switch to the swing phase, the system requires special measure­
ments and prerequisites. The fundamental prerequisite is a sufficient forefoot
load with simultaneous extension of the product's 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.

7.3.3 Sitting down

INFORMATION
If a mode with a high setting for the parameters 'Base Resistance' and/or 'Resistance Gain'
such as 'Extended standing' is configured as the additional mode (2nd mode), switching back
to basic mode (1st mode) must be performed before sitting down (see Page 60). Otherwise it is
not possible to flex the knee joint.
The damping of the product while sitting down ensures that the knees bend
evenly, thereby supporting the contralateral side.
1) Position both feet side by side at the same level.
2) While sitting down, the user should distribute his/her weight evenly
between both legs and use armrests, if available.
3) Move the buttocks in the direction of the backrest and lean the upper body
forward.
