5.4 Static Alignment
+ = anterior placement / – = posterior placement (in relation to the load line)
No. see fig. 6
Required equipment:
743L100 L.A.S.A.R. Posture
To determine the load line
Prosthetic foot (with shoe) on force measurement plate (sufficient load: > 35% body weight)
•
• Other foot (with shoe) on height compensation plate
• The tips of the shoes are in one line
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.
