Otto Bock Taleo Adjust 1C56 Instructions For Use Manual page 21

► TT fittings: Make sure that physiological knee movement in the sagittal
and frontal planes is achieved after the leg begins to bear weight follow­
ing 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 knee joint moves in the medial direction in the second half of
the stance phase, reduce the exterior rotation of the prosthetic foot.
► Once the gait pattern has been optimised with everyday footwear, try
additional heel heights. The heel height affects rollover as it changes the
angle at which the prosthetic foot is loaded.
► Remove the plastic part from the connecting section after dynamic fitting
and the walking exercises are complete.
5.4.1 Replacing the heel wedge
The behaviour of the prosthetic foot at heel strike and during heel contact in
the mid-stance phase can be adapted by replacing the heel wedge. Heel
wedges of various hardness are included in the scope of delivery.
Heel wedge hardness: The colour of the heel wedge indicates the hard­
ness (see fig. 3). Ottobock recommends starting with the preinstalled heel
wedge.
1) Bend the prosthetic foot slightly and remove the installed heel wedge.
2) Align the other heel wedge so the Ottobock lettering is right side up and
the tip points in the anterior direction.
3) Insert the heel wedge into the prosthetic foot (see fig. 4, see fig. 6). To
do so, first insert the tip into the front part of the frame , then push
the heel wedge into the rear of the frame .
6 Use
6.1 Setting the heel height
INFORMATION
First-time use or after an extended break: there may be stiffness when
operating the lock axle and/or adjusting the ankle angle.
► To loosen: slide the lock axle back and forth several times and move
the ankle joint through its entire scope of movement.
The heel height of the prosthetic foot can be smoothly adjusted from 0 mm
to 70 mm.
Size 27 and 28: Set the prosthetic foot to a maximum heel height of
25 mm.
