Troubleshooting - PROTEOR Freedom ShockWave F20 Instrucciones De Uso

5 ACCESSORIES AND COMPATIBILITIES
The foot incorporates a male pyramid link that allows it to be used with female pyramid connectors (refer to our catalog).
6 ASSEMBLY AND PATIENT FITTING
A. Assembly
The ShockWave foot module is pre-assembled consisting of composite components (keel and sole plate), a Spectra sock, and
a foot shell. Stiffening bumpers for increasing heel stiffness are provided. After dynamic alignment, torque pyramid
adjustment screws to the manufacturer's specifications. Secure pyramid adjustment screws with thread locking adhesive
(e.g., Loctite 242).
B. Spectra Socks
A Spectra sock is provided to minimize noise and protect the foot shell/ composite components. The Spectra sock should be
placed over the keel and the sole plate before donning the foot shell. Spectra socks must be replaced at intervals appropriate
to the user's activity level. Failure to inspect and replace the Spectra socks may prematurely wear the foot module and will
void the warranty.
C. Foot Shell
When removing or installing the foot shell, use the Foot Shell Removal Tool (ACC-00-10200-00) to prevent damage to the
foot module. Do not attempt to remove the foot from its shell by pulling out by hand. This may damage the foot, voiding the
warranty.
D. Bench Alignment
Prior to the user donning the prosthesis:
•
Plantarflex/Dorsiflex the foot to match the shoe heel height
•
Adduct/Abduct the socket to provide appropriate frontal plane angle
•
Flex/Extend the socket to provide appropriate sagittal plane angle
•
Move the socket linearly to ensure the weight line falls through the center of the pylon (see illustration)
E. Dynamic Alignment
During loading response, the heel lever stores energy and releases it during midstance. This action provides momentum for
the keel to store energy and release it during terminal stance. To optimize the heel to toe rollover motion, adjust the following
variables:
•
Anterior/posterior foot placement
•
Dorsiflexion/plantarflexion
•
Heel stiffness
F. Troubleshooting
CONCERN
Heel too soft
Heel too hard
Foot module too stiff
Foot module too soft
INSTRUCTIONS FOR USE
SYMPTOM
•
Foot flat occurs too rapidly,
•
Toe feels excessively stiff,
•
Knee hyperextension
•
Rapid knee flexion, instability
•
Heel to toe progression to rapid
•
Lack of energy return sensation
•
Flat spot in rollover motion at slow
cadences
•
Clicking noise at initial contact
•
Excessive toe deflection with high
impact activity
SOLUTION
•
Shift socket anteriorly in relation to
the foot
•
Attach stiffening bumpers. See
Stiffening Bumper Kit label for
installation details.
•
Shift socket posteriorly in relation to
the foot
•
Verify appropriate foot module
category
•
Consider a lower category foot module
•
Consider a higher category foot
module
