Dynamic Alignment - Össur CHEETAH Instrucciones De Uso

sound side with shoe to compensate for vertical compression and
plantar flexion
Note: The recommendations for bench alignment are used as a starting
point. Definitive alignment will be achieved during dynamic assessment.
cUTTING FOOT MOdULE
• Before cutting check for enough clearance.
• Measure for length and add 50mm (2") to compensate for
measurement error. The final height is approximately 25mm (1") taller
than the sound side.
• Clamp foot module in vice. Use a sharp fine tooth hacksaw blade.
• Sand away any sharp edges.
• Secure foot to using fitting clamps or synthetic plaster bandages.
• Cut again if necessary.
• Lowest hole position is in 30 cm (12") when pylon is vertical.
dRILLING FOOT MOdULE aTTacHMENT HOLES
• Back-up foot module when drilling using wood block or discarded
carbon fiber section and clamp securely.
• Use drill guide template to locate holes.
• Use sharp drill bits. Suggestion: Bullet nose or solid carbide tipped
drill bits.
• Drill size:
Cat 1-6 8,4mm (21/64")
Cat 7-9 11mm (7/16")
• Drill speed 1200-1800 RPM.
• Feed drill slowly with light intermittent pressure - do not force.
• Foot is now ready for assembly.

dYNaMIc aLIGNMENT

Physical ability and length of residual limb will result in different
alignment. Best performance will be achieved with best achievable
symmetry of gait. Each athlete will have her/ his own optimal alignment,
which relates to the individual's running style. Optimal alignment is
critical in order to reduce energy expenditure and eliminate excessive
muscle and ligament strain while running.
• Check for best symmetry of gait
• Stride length can be affected by A-P position socket to foot
• Vertical deflection is in the average between
50mm (2") to 75mm (3")
TROUbLE SHOOTING
Exclude reasons related to socket fit. Try to achieve symmetry in running
as close as possible. The symmetry in running should be assessed at
maximum speed.
FURTHER REcOMMENdaTIONS:
For track & field events shoes usually feature spikes:
The sole of the spare shoe is then attached to the prosthetic foot in the
following way:
• Cut off the sole area where the spikes are attached (1).
• Remove the insole
• Bond leather to the back side of the prepared part.
• Sand the surfaces (2).
• Bond assembly to the ground contact area (3).
