Dynamic Trial Fitting; Optional: Installing The Foam Cover - Ottobock 1D35 DynamicMotion Instrucciones De Uso

5.1.3 Dynamic Trial Fitting

• Adapt the alignment of the prosthesis in the frontal plane and the sagittal
plane (e.g. by making angle or slide adjustments) to ensure an optimum
gait pattern.
TT fittings:Make sure that physiological knee movement in the sagittal
•
and frontal plane is achieved when the leg begins to bear weight after
the heel strike. Avoid medial movement of the knee joint. If the knee joint
moves in the medial direction in the first half of the stance phase, medial­
ise the prosthetic foot. If the medial movement occurs in the second half
of the stance phase, reduce the exterior rotation.
• Remove the adapter cover from the prosthetic foot after completion of
the dynamic trial fitting and gait training exercises.

5.2 Optional: Installing the foam cover

A connecting element (such as a connection plate, connection cap or foam
connection cap) provides a detachable connection between the foam cover
and the prosthetic foot.
Required materials: Degreasing cleaner (e.g. 634A58 isopropyl alco­
>
hol), 636N9 contact adhesive or 636W17 plastic adhesive
1) Measure the distance from the knee rotation point to the desired end of
the foam cover and add the compression allowance: 10 mm for poly­
ethylene foam, 30 mm for polyurethane soft foam. For TF prostheses,
add twice the compression allowance because a compression allowance
is needed both above and below the knee axis.
2) Cut the pre-shaped foam cover to length and fit it in the proximal area on
the prosthetic socket.
3) Pull the foam cover over the prosthesis.
4) Set the connecting element onto the footshell or prosthetic foot. Depend­
ing on the version, the connecting element engages in the edge or sits
on the foot adapter.
5) Mount the prosthetic foot on the prosthesis.
6) Mark the outer contour of the connecting element on the distal face of
the foam cover.
7) Dismount the prosthetic foot and remove the connecting element.
8) Clean the connecting element using a degreasing cleaner.
9) Glue the connecting element onto the distal face of the foam cover
according to the marked outer contour.
10) Let the glue dry (approx. 10 minutes).
11) Mount the prosthetic foot and adapt the exterior cosmetic cover shape.
Take into account compression due to cosmetic stockings or SuperSkin.
