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

Use

9.1.2 Walking

Initial attempts at walking with the prosthesis always require the instruction of trained, quali­
fied 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 between both legs
3) Move the buttocks in the direction of the backrest and lean the upper body forward.

9.1.4 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 cockpit
app or remote control (optional accessory) (see Page 68), resistance is also reduced in the
flexion direction.

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 distributed on feet.

9.1.6 Walking up stairs

Walking up stairs step-over-step is not possible.
1) Hold the handrail with one hand.
2) Place the foot of the contralateral leg on the first step.
Bring up the leg with the prosthesis.
