Dynamic Trial Fitting; Checking The Factory Settings - Ottobock 3R80 Instrucciones De Uso

+ = anterior placement / – = posterior placement (in relation to the load line)
No. see fig. 6
Optimise the static alignment solely by changing the plantar flexion. Adjustment is performed only
with the anterior and posterior set screws of the tube adapter on the prosthetic foot.

5.5 Dynamic Trial Fitting

CAUTION
Adjusting the Settings
Fall due to incorrect or unfamiliar settings
Only adapt the settings to the patient gradually.
►
Explain the effects of the adjustments on the use of the prosthesis to the patient.
►
During dynamic trial fitting, the alignment and settings of the prosthesis are checked and adapted
for optimum walking according to the needs and abilities of the patient.
The patient has to learn the safe use of the prosthesis through intensive training.
The following subsections describe the adjustment possibilities for adapting the product to the
patient.
The list below provides an overview of the sequence for working through the subsections:
•

Checking the Factory Settings

• Setting Flexion Damping
• Setting Extension Damping
• Setting Stance Phase Damping
• Setting the Stance Phase Damping Threshold
The adjustment is illustrated graphically in the supplied Quick Start Guide.
