Static Alignment; Dynamic Trial Fitting; Optimising The Heel Characteristics; Optional: Installing The Foam Cover - Ottobock 1M10 Adjust Instrucciones De Uso

Perform the assembly and alignment of the prosthetic components in the alignment apparatus according to
the following specifications:
Sagittal plane
Heel height: Effective heel height (shoe heel height - sole thickness of forefoot) + 5 mm
Exterior foot rotation: approx. 5°
Anterior placement, middle of the prosthetic foot to the alignment reference line: 30 mm
Connect the prosthetic foot and prosthetic socket using the chosen adapters. The instructions for
use of the adapters must be observed.
Determine the centre of the prosthetic socket with the 50:50 gauge. Align the prosthetic socket
centrally to the alignment reference line.
Socket flexion: Individual residual limb flexion + 5°
Frontal plane
Alignment reference line of prosthetic foot: between big toe and second toe
Alignment reference line of prosthetic socket: along the lateral patella edge
Observe the abduction or adduction position.
TF bench alignment
► Observe the information in the prosthetic knee joint instructions for use.

5.1.3 Static Alignment

If necessary, the alignment recommendations (TF modular leg prostheses: 646F219*, TT
•
modular leg prostheses: 646F336*) may be requested from Ottobock.
• Ottobock recommends checking the alignment of the prosthesis using the L.A.S.A.R. Posture
and adapting it as needed.

5.1.4 Dynamic Trial Fitting

• Adapt the alignment of the prosthesis in the frontal plane and the sagittal plane (e.g. by mak­
ing 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, move the prosthetic foot in the medial direction. If the medial movement occurs in the
second half of the stance phase, reduce the exterior rotation of the prosthetic foot.

5.1.4.1 Optimising the heel characteristics

INFORMATION
Changing the configuration of the function module has no effect on the load line while standing.
The heel characteristics are adjusted with the function module. The following settings are pos­
sible:
Heel strike Selected configuration (see fig. 2)
Soft 1
Moderate 2 (delivery condition)
Firm 3
► Turn the function module to the desired configuration (see fig. 6).

5.2 Optional: Installing the foam cover

The foam cover sits between the prosthetic socket and prosthetic foot. It is cut longer in order to
compensate for the movements of the prosthetic foot and prosthetic knee joint. During flexion of
the prosthetic knee joint, the foam cover undergoes posterior compression and anterior elonga­
tion. The foam cover should be stretched as little as possible in order to increase its service life.
