Sitting Down; Sitting; Standing Up; Walking Up Stairs - Otto Bock C-Leg 3C98-3 Instructions For Use Manual

10.1.3 Sitting down

The resistance 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
3) Move the buttocks in the direction of the backrest and lean the upper body forward.

10.1.4 Sitting

INFORMATION
While sitting, the knee joint switches to energy saving mode. This energy saving mode is activated regardless of
whether the sitting function is enabled in the adjustment software or not.
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.
If the sitting function is activated in the adjustment software and switched on via the remote
control or app, resistance is also reduced in the flexion direction.

10.1.5 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.
