Adjustment with Ottobock C-Soft
STP Flexion Damping
The parameter 'STP Flexion Damping' is the resistance against flexion of the knee which is required for descend­
ing stairs or ramps or for supported sitting motions.
A recommended value is preconfigured in the delivery condition.
Preliminary adjustment:
For verification, the patient should sit down on a chair while supporting him or herself with the hands on the arm­
rests. The patient lets him or herself sink into the orthosis and feels the supporting effect of stance phase damping
(STP Flexion Damping).
Fine adjustment:
Have the patient walk down a ramp and then stairs, keeping one hand on the handrail for safety. If the resistance is
subjectively too low or too high, it can be adjusted accordingly.
The goal is to find a good compromise setting that permits sitting down in comfort and also walking on ramps and
stairs safely.
STP Flexion Damping Plus (only in expert mode)
CAUTION
Very high value for the elevated flexion resistance setting (STP Flexion Damping Plus)
When elevated flexion resistance (STP Flexion Damping Plus) is set to a very high value, problems may result
while walking down stairs and ramps. Elevated damping may still be active during the first step (especially when
the parameter 'STP Flexion Plus Time [*20ms]' is set to a long time). This prevents correct flexion of the knee
joint.
This may lead to falling caused by:
► Unexpected, high stance phase damping during the transition from a level surface to the first step of a stair­
case or when negotiating a ramp.
→ Familiarise the patient with the altered behaviour of the system after changing this setting.
→ Point out to the patient that special caution is required for the first step on a ramp or stairs. Before negotiating
a ramp or stairs, pause briefly and test whether regular stance phase damping (STP Flexion Damping) is act­
ive.
INFORMATION
The value selected for elevated flexion resistance (STP Flexion Damping Plus) cannot be lower than the value
selected for stance phase damping (STP Flexion Damping). Upon attempting to enter a lower value, this value is
automatically set to the value of the parameter STP Flexion Damping.
