5.3 Static Alignment
Item see fig. 6, see fig. 7
Required equipment:
743L100 L.A.S.A.R. Posture
To determine the load line
as follows:
• Prosthetic foot on force plate (sufficient load: > 45% body weight)
• Other foot (with shoe) on height compensation plate
• The tips of the shoe and prosthetic foot are in one line
Optimise the static alignment solely by changing the plantar flexion. Adjust­
ment is performed only with the distal and proximal set screws of the socket
adapter on the foot adapter.
Exterior foot rotation:
0°
Foot flexion in m–l direction:
0°
Position of the mark
0 mm
Position of the compromise pivot point
>= 15 mm
5.4 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 and running according to the
needs and abilities of the patient.
The patient has to learn the safe use of the prosthesis through intensive
training.
The subsections that follow describe activities to be performed in the course
of the dynamic trial fitting to adapt the prosthesis to the patient.
5.4.1 Checking the Stiffness and Length of the Prosthetic Foot
1) In the 647H545 Quick Reference Guide, note the section "Check of stiff­
ness and length of the 1E90" (see page 8).
