Mode Switching - Ottobock C-Brace Gebrauchsanweisung

LOM Mode
CAUTION
Risk of falling when walking backwards
When putting down the toe first when walking backwards, the orthosis may switch from high stance phase resist­
ance to swing phase resistance.
► Active flexion in the hip at this point in time can lead to falling.
→ Actively secure the orthosis with the residual musculature while walking backwards.
Lock mode: 1st mode with blocked knee flexion
This mode gives the patient a certain feeling of safety when first using the orthosis, since the orthosis will not bend,
but will straighten. The knee flexion is locked in the stance phase. Stance phase damping is set to the maximum.
Nevertheless, the swing phase is triggered when walking.
To allow the user to sit down with the knee joint flexed, it is necessary to manually switch to 1st mode before sitting
down.
STA Mode (Stance Function Timer [*20ms])
High stance phase damping (STP Flexion Damping) is automatically activated during an extended stance phase
with the knee slightly flexed (knee angle approx. 5° to approx. 20°). This occurs after the time 'Stance Function
Timer [*20ms]' has elapsed.
INFORMATION: If this mode is not desired, it can be deactivated by adjusting the parameter 'Stance Function
Timer [*20ms]'.

8.4.1 Mode Switching

INFORMATION
Before the first step, always verify whether the desired mode corresponds to the respective movement type.
Activating 1st mode:
INFORMATION
Regardless of the mode selected before switching, this process always switches to 1st mode.
1) Push and hold button 1.
→ A long beep signal is emitted.
2) Take the weight off the orthosis.
→ A short beep signal is emitted.
→ The orthosis has successful switched to 1st mode.
C-Brace
1. Upper button, button 1 – return to 1st mode
2. Lower button, button 2 – switching to 2nd and LOM mode
INFORMATION: With the exception of 1st mode, some movement patterns are lim­
ited or not possible in all other modes.
