Otto Bock Freestyle Swim LP2-W2 Instructions For Use Manual page 17

Dorsiflexion/plantar flexion: Adjust the prosthetic foot to the heel height of
the shoe. (The prosthetic foot is designed for shoes with a heel height of
10 mm.)
Adduction/abduction: Adjust the angle of the prosthetic socket in the front­
al plane.
Flexion/extension: Adjust the angle of the prosthetic socket in the sagittal
plane.
Linear shifting of the prosthetic socket: Shift the prosthetic socket so that
the plumb line runs along the front edge of the adapter on the prosthetic foot
(see fig. 1).
TF bench alignment
► Observe the information in the prosthetic knee joint instructions for use.
5.1.3 Static Alignment
• 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 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, 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.
• Remove the plastic protector from the pyramid after completing the
dynamic fitting and the walking exercises.
Heel too soft
Symptoms
• Foot makes full ground contact too
quickly
• Forefoot feels too stiff
• Knee goes into hyperextension
Heel too hard
Symptoms
• Fast knee flexion, low stability
• Transition from heel strike to toe-off too
fast
Bench alignment process
Possible solutions
• Shift prosthetic socket forward relative
• Use a heel wedge
Possible solutions
• Shift prosthetic socket back relative to
to the foot
