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

9.1.2 Walking

Initial attempts at walking with the prosthesis always require the instruction of
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.
Switching to the swing phase requires that the prosthesis roll over to the front
out of the stride position.

9.1.3 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
3) Move the buttocks in the direction of the backrest and lean the upper body

9.1.4 Sitting

INFORMATION
While sitting, the knee joint switches to energy saving mode. This energy saving mode is activ­
ated 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 horizontal 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 direc­
tion.

9.1.5 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 distrib­
between both legs and use armrests, if available.
