Motion foot MX Dynamic Prosthetic Foot
User Guide
Introduction
Thank you for purchasing the Motion Foot ® MX. No other foot has the anatomical range of motion of the Motion Foot® MX. This results in smooth, gliding gait on flat 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 Motion Foot ® 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 flexion* and dorsi flexion** resistance
- Moving fulcrum keel design for dynamic foot response
- Ankle Lock for ease of donning shoes/driving, etc.
- Plantar flexion – the ankle motion as the foot goes to the floor when the heel strikes the ground
** Dorsi flexion – the motion as the shin moves over the ankle and the angle between the shin and foot falls below 90 degrees
Foot Components
Special Precautions
Risk Management
To minimize the risk of device damage or injury to the user while maximizing
the functions of this device, follow the instructions for installation, and
use this device as described in this manual.
Ankle Lock
Do not use the Ankle Lock mechanism for walking or running. It should be used
for driving, donning/doffing 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 flexion 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-flexed 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 flexion when ascending or decen ding 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.
Serious Incidents
In the unlikely event a serious incident occurs in relation to the use of the
device, users should seek immediate medical help and contact their prosthetist
at the earliest possible convenience. Clinicians should contact Motion
Control immediately in the event of any device failure.
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 flexion resistance when descending hills, or increasing the dorsiflexion resistance when changing to a higher heel height shoe. To increase Plantar Flexion (PF) turn the index mark counterclockwise on the PF adjustment screw to a higher number. Note, increasing plantar flexion too much will result in the knee being unstable. To decrease, turn the screw clockwise to a smaller number. To increase Dorsiglexion (DF) resistance, turn the index mark counter-clockwise on the DF adjustment screw to a higher number. Note, increasing dorsiflexion 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 doff 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 dorsiflex, but it will not lock until the ankle reaches full dorsiflexion. 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 different 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 flexion of the MotionFoot ® MX, if only the heel of the
foot purchases on a step or ladder rung, the foot will go into plantar
flexion, allowing it to slip off 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 emanate from inside the foot, you should schedule an appointment with
your prosthetist immediately.
If fluid 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.
Single Patient Use
Each amputee is unique. The shape of their residual limb and the tasks an
amputee performs during the day require specialized design and adjustment of
the prosthesis. Motion Control products are manufactured to be fit to one
individual.
Disposal/Waste Handling
This device, including any associated electronics and batteries should be
disposed of in accordance with applicable local laws and regulations. This
includes laws and regulations regarding bacterial or infectious agents, if
necessary.
Limited Warranty
The Motion Foot® 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:
Prosthetic services for fitting and maintaining the prosthesis.
- Damage caused by neglect, misuse or improper operation.
- Damage due to accident, fire, water, vandalism, unsuitable environmental conditions.
- Replacement parts not approved or recommended by Motion Control.
- Modifications 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 specified by the Seller.
