Dynamic Alignment - Össur PFP0 Serie Instrucciones Para El Uso

after contact with fresh water. Fresh water: Includes tap water. Excludes
salt and chlorinated water.
FOOT COVERS (Figure 2)
The device is designed to be used with an FST Foot Cover and Spectra sock.
Both the practitioner and user must be familiar with the relevant foot cover
Instructions For Use before fitting.
Use a shoehorn to avoid damaging to the device and foot cover when
donning and doffing.
Donning – To don, ensure the device is placed completely into the foot
cover (Figure 2a).
Doffing - Removing the device from the foot cover (Figure 2b).
N.B. Use a Spectra sock as shown in Figure 1.
DEVICE ALIGNMENT
N.B. Remove the yellow sticker on top of the pyramid before performing
device alignment.
BENCH ALIGNMENT (Figure 3)
• Fit device with Spectra sock and selected foot cover.
• Adjust to appropriate heel height (using selected shoe).
• Introduce appropriate socket angles: flexion/extension and abduction/
adduction.
• Divide the foot cover into 3 equal portions.
• The load line should fall in the middle section on the 1/3
line, or slightly anterior.

DYNAMIC ALIGNMENT

The foot provides progressive energy-storing during the whole stance phase,
and a powerful push-off at the end of stance. Due to this, it is expected that
under load, the load line will move anteriorly to the 1/3 line. The heel-to-
toe action can be influenced by:
• Shoe performance
• Anterior-Posterior positioning of the device
• Dorsi-plantarflexion
N.B: For Transfemoral amputees please follow the recommendations for the
alignment of the corresponding Össur knee joint.
HEEL STIFFNESS
Heel too soft
Symptoms:
• Device will come to flat position too early (User 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
Action:
• Shift socket anterior (or device posterior)
Heel too hard
Symptoms:
• Rapid heel-to-toe movement.
• At initial contact the user has poor control of the prosthesis
