SAFETY PRECAUTIONS

Caution: Statement that alerts the user to the possibility of a problem
with the device associated with its use or misuse.
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 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 socks 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).
