TRAINING TIPS
Start the training after the proprio foot ® is aligned and calibrated.
Ensure full function with all connections secured.
Charging: Train the user on how to charge the unit.
Heel height
adjustment:
Encourage the user to switch shoes or try out barefoot walking using the heel height adjustment.
Curbs: Ask the user to take a long step onto and down a curb. This will limit the ankle adaptation. This will
prevent false ankle adaptation.
Note: Walking across high curbs may initiate the stair response!
Sitting: Ask the user to sit down and position the shank at over 20° relative to the ground (stretch legs). To allow
for the Relax Mode the prosthesis has to be slightly unloaded PROPRIO FOOT will move into a plantar
flexed position (toe down).
Chair Exit Mode: Ask the user while in a seated position to move the prosthesis under or close to the chair. PROPRIO FOOT
will dorsiflex (toe up) to facilitate standing up.
Level ground: Ask the user to walk at slow and fast speed. Observe the dorsiflexion in swing.
Ramps: Ask the user to walk up and down on a shallow and steep ramp. Observe the ankle adaptation and ask
whether the user can sense it.
Stairs: Ask the user to walk up and down on stairs. Advise to lead with the prosthetic side upstairs and to lead
with the prosthetic side when going down. This will provide stair adaptation after the first step on stairs.
Note: Instruct the user to be careful walking downstairs for the first time, since they will not be used to the
dorsiflexed ankle position. Encourage the user to switch shoes or try out barefoot walking using the heel
height adjustment.
Toe lift: Very slow walking speed won’t trigger toe lift.
Half step: Sharp turns, zigzagging or stepping up high curbs may cause dorsiflexion.
Power loss: Results in plantarflexion.
Motor stuck: Light tapping on the toe or heel can free it up.

ELECTROMAGNETIC COMPATIBILITY PRECAUTIONS
The proprio foot ® needs special precautions regarding electromagnetic compatibility
(EMC)
. Specifically it
needs to be installed and put into service according to the EMC information provided as follows:
• The proprio foot
® should not be used adjacent to or stacked with other equipment. In case adjacent or
stacked use is necessary, the proprio foot ® should be observed to verify normal operation in the configuration
in which it will be used.
• The proprio foot
®
may be susceptible to electromagnetic interference from portable and mobile RF
communications devices such as mobile (cellular) telephones.
• The proprio foot
®
may be interfered with by other equipment, even if that other equipment complies with
cispr emission requirements.
