User Guide
Introduction
Thank you for purchasing the Motionfoot®MX. No other foot has the anatomical range of motion of
the Motionfoot®MX. This results in smooth, gliding gait on at terrain, and unparalleled stability on
descending slopes.
Please take a moment to study this manual as it describes the advantages, functions, adjustments, and
warnings regarding the Motionfoot®MX,for you to maximize safety, comfort, and reliability.
Features of the Motionfoot®MX
• A full anatomical 50 degrees range of motion
• Wearer adjustable plantar exion* and dorsi exion** resistance
• Moving fulcrum keel design for dynamic foot response
• Ankle Lock for ease of donning shoes/driving, etc.
* Plantar exion - the ankle motion as the foot goes to the oor when the heel strikes the ground
** Dorsi exion - the motion as the shin moves over the ankle and the angle between the shin and foot falls below 90
degrees
Foot Components
2

Ankle Lock
Do not use the Ankle Lock mechanism for walking or running. It should be used for driving,
donning/dong shoes, and other light, non-ambulatory activities.
Driving
The foot should be in the locked position whenever being used for driving.
Kneeling and sitting
The foot will go into plantar exion when sitting and kneeling. Upon standing, care must be taken
to return the foot to a neutral position to prevent knee hyperextension or tripping on the plantar-
exed foot.
Stairs/Ladders
Care must be taken while climbing stairs and ladders so the weight line remains anterior to the
center of rotation of the ankle, to prevent the foot from going into plantar exion when ascending
or decending stairs, ladders, etc.
Declines
When switching direction on a descent, the foot must return to a neutral position before level or
uphill ambulation.
Dust, Dirt, and Water
Prevent dust, dirt and water from entering the foot shell. Always keep a Spectra Sock between the
foot shell and the foot. If the inside of the foot shell becomes contaminated, remove the foot shell,
thoroughly clean the foot and inside of the shell, and replace the Spectra Sock if necessary.
Special Precautions
Resistance Adjustments
While it is unlikely you will make changes to the resistance
settings, there could be instances when you want to adjust the
foot. This may include decreasing the plantar exion resistance
when descending hills, or increasing the dorsi exion
resistance when changing to a higher heel height shoe.
To increase Plantar Flexion (PF) turn the index mark counter-
clockwise on the PF adjustment screw to a higher number.
Note, increasing plantar exion too much will result in the
knee being unstable. To decrease, turn the screw clockwise to
a smaller number.
To increase Dorsi Flexion (DF) resistance, turn the index mark
counter-clockwise on the DF adjustment screw to a higher
number. Note, increasing dorsi exion too much will result
in a hyperextension moment at the knee when walking. To
decrease, turn the screw clockwise to a smaller number.
Ankle Lock Button
The Ankle Lock Button is for safety while driving, and to make it easier to don and do shoes and socks.
It should not be used for walking or running.
To lock the ankle, push the button on the right side of the foot (it is the same for a right or left foot) and
slide it to the left. This will allow the ankle to dorsi ex, but it will not lock until the ankle reaches full
dorsi exion. To unlock, push the left side and slide it to the right.

Changing Shoes
Since the Motionfoot®MX has 50 degrees range of motion, you are able to wear shoes with dierent heel
heights. Your prosthetist will initially set up the foot with your lowest heel height shoes (usually tennis
shoes or barefoot). When you change to a higher heel height shoe, this will change where the foot stops
when rolling over the toe. This will take two or three steps to become accustomed, so care should be taken.
Stairs and Ladders
With the free plantar exion of the Motionfoot®MX, if only the heel of the foot purchases on a step or
ladder rung, the foot will go into plantar exion, allowing it to slip o the step or ladder rung. This could
result in a fall. Make sure the foot is supported in front of the ankle joint on the ball of the foot by either
the step or ladder rung.
Maintenance
No maintenance by the wearer is required for the foot. Indeed, the foot should not be oiled or sprayed
with any solvents or lubricants. This will void the warranty.
The inside of the foot shell should be kept free of water, sand, grit, rocks, or any other contaminants. If
the inside of the foot shell is contaminated, your prosthetist should remove the foot shell, remove the
contaminant and replace the Spectra Sock. Failure to do this will destroy the carbon foot plates and void
the warranty.
If any clicks, creaks or other noises eminate from inside the foot, you should schedule an appointment
with your prosthetist immediately.
If uid is seen leaking from the foot, see your prosthetist immediately.
Your prosthetist should follow up at a minimum, once yearly, to ensure proper functioning of the foot.
Limited Warranty
The Motionfoot®MX is provided with a 2 year warranty, with the exception of the foot shell, which
has a 6-month warranty. After the warranty period, repairs are guaranteed for a period of 90 days.
Determination of the damages or defects to be covered under the Limited Warranty shall be made by
Motion Control personnel.
Warranty does not include:
1. Prosthetic services for tting and maintaining the prosthesis.
2. Damage caused by neglect, misuse or improper operation.
3. Damage due to accident, re, water, vandalism, unsuitable environmental conditions.
4. Replacement parts not approved or recommended by Motion Control.
5. Modications to the equipment which occur during the period of the Agreement except by mutual
consent of the parties in writing, including payment of additional charges as specied by the Seller.
