Dynamic Alignment - Össur PRO-FLEX LP Instrucciones De Uso

Precaution: Should be taken to avoid the hazard
Note: Possibility of a technical damage or malfunction of the device.
Caution: Make sure that the user knows if he/she feels or notices any
change of function or alignment of the device, he/she should contact his
healthcare practitioner. This noticeable function loss may be the result of
reduced stiffness or loss of support.
Note: The foot is designed to be used with a spectra sock and a foot
cover.
BENCH ALIGNMENT (Figure 4)
• Fit foot with selected cover.
• Adjust to appropriate heel height (using the shoe).
• Introduce appropriate socket angles flexion/ extension and
abduction/adduction.
• Divide the foot cover into 3 equal portions.
• The load line should fall at the junction of the posterior and the
middle third portions as shown in figure 3.
• The 1/3 position is marked on the inside wall of the foot cover.

DYNAMIC ALIGNMENT

The heel stores energy after initial contact, slowly releasing it at
midstance. The forward momentum generated by this action results in
the toe being loaded for optimum energy release at terminal stance. The
heel to toe action can be influenced by:
• A-P positioning of foot
• Dorsi-Plantarflexion
• Heel Stiffness
HEEL STIFFNESS
Heel too soft
Symptoms
• Foot will come to flat position too early (amputee feels he/she is
sinking into a hole).
• Extra energy is required to climb up over the toe.
• Toe will feel too stiff
• Knee may hyperextend.
Actions
• Shift socket anterior (anterior or foot posterior).
Heel too hard
Symptoms
• Rapid heel to toe movement.
• At initial contact the amputee has poor control of his prosthesis.
• Minimal energy return feeling.
• Knee may become unstable.
Actions
• Shift socket posterior (or foot anterior).
PROTECTIVE FILM ON PYRAMID
The protective film protects the pyramid from scratching. Remove the
film when the fitting is complete.
