Intended Use
The Motion Foot® SLX hydraulic prosthetic foot is intended for use
in lower extremity prostheses. The Motion Foot SLX sets itself apart
by combining a two-spring prosthetic foot design with a hydraulic
mechanism that allows for plantar and dorsiexion Range of motion.
Fillauer has designed the Motion Foot SLX to support each phase of
foot function in the gait cycle—from heel strike, to mid-stance, to toe
o. The result is a foot that adapts well to sloped conditions, creating
early stance phase stability with solid energy return. This provides
unsurpassed smoothness, stability, and performance from initial
contact, to mid-stance, to terminal stance.
Indications
• Moderate to active transtibial or transfemoral amputees as dened
by functional K3 activity levels
• Unilateral or bilateral patients
• Patients that would benet from increased exibility and smooth
rollover

Storage and Handling
It is recommended that prosthetic feet are stored between -5 – 50°C in
a clean, dry environment away from harsh chemicals (chlorine, acids,
acetone, etc.).
Warnings and Precautions
CAUTION: Do not exceed the specied weight limit
CAUTION: All fasteners must have thread locker applied
and must be torqued according to the manufacturer’s
instructions prior to nal delivery.
CAUTION: The Motion Foot SLX is designed to be
maintenance free and should not be disassembled. The
hydraulic unit on the foot is permanently attached to the
main and top spring and should not be removed.
CAUTION: For patient safety and device compatibility, only
Fillauer or equal, ISO 10328 compliant, pyramid receivers
should be used with thisfoot.
CAUTION: Abnormal or improper environmental conditions
will lead to malfunctioning and damage of the prosthesis
and is not covered under the warranty of the device. This
prosthetic/orthotic component must not be subjected
to dust/debris, liquids other than fresh water, abrasives,
vibration, activities which would damage the biological
limb, or extreme temperatures (<-5°C or >50°C). Do not
allow debris or liquids to remain in the prosthesis and its

5
components during use. Rinse the foot with fresh water and
dry immediately after exposure.
CAUTION: The foot unit is waterproof to 1 meter; however,
if the foot is submerged, the foot and foot shell should
be rinsed with fresh water and dried immediately to
remove salt, chlorine, or debris. The foot shell and sock will
experience signicant deterioration if not allowed to fully
dry before return to normal use and are not covered under
warranty for this failure.
NOTICE: Fillauer has tested (ISO 10328) and recommends
the use of standard adult endoskeletal components from
Fillauer together. Components from other manufacturers
may or may not be compatible. Failure due to use of other
manufacturers’ products is not covered under warranty.
NOTICE: The foot should be inspected by the clinician every
6 months for signs of abnormal wear and to assure that the
attachment/alignment screws are secure.
NOTICE: The foot stiness is based on weight and activity
level. Please provide accurate patient information so that
the appropriate foot may be selected.
NOTICE: Attachment, alignment, and delivery of the foot
must be performed by or under the direct supervision of
a qualied prosthetist. Any adjustment or modications
should be done by the clinician and not by the user.
NOTICE: If any serious incidents occur in relation to the
usage of the device, contact your Fillauer Representative
and the competent authority in your country.
NOTICE: Avoid carrying loads over 50lbs. (22.6kg). Lifting
heavy objects could put the wearer above the limits of the
carbon spring elements causing failure.
NOTICE: The patient’s weight should be regularly
monitored. Extra weight could exceed the weight/activity
category and a new conguration would be necessary.
Contact Fillauer with concerns.

Alignment (Specications &
PreparationsBefore Use)
Proximal Attachment
Attachment of the foot may be achieved via the proximal pyramid to any
ISO 10328 compliant, Fillauer or equal, standard adult pyramid receiver.
Torque all set screws to the setting specied by the manufacturer of
the pyramid receiver. For Fillauer components, this is 15N·m. Proper
thread locker must be used for nal delivery per the component
manufacturer’s specications.
Static and Bench Alignment
Standard bench alignment techniques may be used for the Motion
Foot SLX foot (Figure2). Before aligning, the initial heel height should
be established. The Motion Foot SLX is designed for a 3/8 in. or 1 cm
heel height. The initial heel height can be established with a simple
spacer under the heel. The top of the pyramid should be parallel with
the work surface before proceeding with alignment. A backward leaning
pylon indicates that the heel height is too low and will make late-stance
rollover dicult.

7
Transtibial Bench Alignment
The foot should be set in the proper amount of inset found in
the evaluation. When using separate suspension and attachment
components, the foot may be slightly inset 1 – 12 mm depending on
the limb length. Short limb lengths are set with very little inset of 2 – 3
mm and longer limb lengths may tolerate a greater varus thrust at
10 – 12 mm. The longitudinal axis of the foot will be externally rotated
approximately 5° by aligning the medial border of the foot with the line
of progression.
Transtibial Transfemoral
Bisect the socket in the sagittal
plane
Follow knee manufacturer’s
guidelines for bench alignment
5° of socket exion, plus any
exion contracture
A plum-bob or laser line
should bisect the socket and
fall through the junction of the
posterior and middle thirds of
the foot.
5° of toe out
Use the heel height of the
patient’s shoe or an equivalent
heel wedge.
Transtibial Static Alignment
Static alignment should always be done inside the parallel bars. They
will sense hydraulic movement of the ankle, but should not feel like
they are falling forward or backward. Use alignment to position the foot
where they feel most balanced.
Symptom Alignment Change
Falling backward Shift the foot posterior relative to the socket
Falling forward Shift the foot anterior relative to the socket

8
Transfemoral Bench Alignment
Alignment at the transfemoral level should be consistent with the
instructions provided by the manufacturer of the prosthetic knee in use.
Dynamic Alignment
The Motion Foot SLX hydraulic Range of motion allows it to conform
well to the ground. This characteristic may make the foot appear to be
properly aligned after the static alignment. Small adjustments in the
alignment however will smooth the transition from heel to toe, optimize
gait and eciency. Patient feedback during this process is essential. In
the dynamic alignment of the foot, the socket exion angle and heel
stiness are altered to achieve optimal alignment and patient gait.

• Dorsiexion resistance aects the user’s gait through midstance as
the body travels over the foot.
Please walk the tester at least 100 meters before nalizing the hydraulic
resistance settings to stabilize the hydraulic uid viscosity.
• Check for smoothness of gait and ground contact during stance
phase.
• If the heel is too soft, there may be delayed heel rollover from heel
strike to midstance. Dorsiexing the foot or increasing plantarexion
resistance may solve this issue.
• If the heel is too rm, heel rollover may be too rapid from heel strike
to mid stance. Also, patient may complain of anterior distal pressure.
Plantarexing the foot or decreasing plantarexion resistance may
solve this issue.
• If the anterior keel rollover progresses too quickly from midstance
to toe loading, the patient may say that they are “walking up a hill.”
Plantarex the foot to or increase dorsiexion resistance provide
more anterior support.
• If the anterior keel rollover hesitates from midstance to toe loading,
the patient may say that they are “walking down a hill.” Dorsiex
the foot or decrease dorsiexion resistance to increase the rate of
rollover.
If a smooth stance phase of gait cannot be achieved, contact Fillauer for
additional assistance.

Foot Shell and Spectra Sock
(ConsumableComponents)
The Motion Foot SLX uses a unique cosmetic foot shell that is exible
and durable (sold separately). Use care in the installation and removal of
the foot shell to maintain its appearance and durability. Always use the
shell with an internal Spectra Sock (included). Never use a sharp-edged
tool such as a screwdriver to install or remove the foot shell.
Heel Lock
Figure 3
Installation
• Pull the Spectra Sock provided onto the foot from toe to heel, pulling
excess material to the ankle so that it does not bunch under the heel
or toe of the foot.
• Insert the forefoot into the foot shell as far as possible. Set the heel
on a supportive surface with the toe up and push the shell onto the
foot until the toe is in position.
• Rotate the foot side to side to allow the foot shell to slide onto the
heel.
• Push the foot shell up onto the heel or, if necessary, insert a shoehorn
into the foot shell and allow the heel to slide down a shoehorn
into the heel lock. The heel must lock (Figure 3) in place for proper
function and safety.
• The Spectra Sock should be inspected and replaced if needed
every 3-6 months by the prosthetist. The plantar surface of the foot
should be inspected at this time and if there is excessive wear of the
protective soling, it should be replaced.
• The foot shell should be inspected daily by the user and replaced by
the clinician when tears or breaks are evident in the surface of the
shell.
Removal
• Place the foot on the bench so that the heel is hanging over the edge
of the bench.

12
• Apply downward force to the top portion of the foot shell at the heel
and the heel plate should pop out of the heel lock, allowing removal
of the foot shell by hand.
• If the foot shell is too tight, a smooth-edged shoehorn may be used to
disengage the heel lock.
Compatibility
Fillauer feet are appropriate for use with Fillauer or equal, ISO 10328
compliant, Endoskeletal components. A Fillauer spectra sock and foot
shell should be used with this device, the t of other manufacturers
shells cannot be guaranteed.

User Instructions
The providing health care professional must review the following
information directly with the user.
Care and Maintenance
WARNING: If the foot performance changes or it begins to
make noise, the patient should immediately contact his or
her practitioner. These things may be as sign of a failure
of the foot or other part of the prosthesis that could
result in a fall or other serious injury.
CAUTION: The foot should be inspected by the clinician
every 6 months for signs of abnormal wear and to assure
that the attachment/alignment screws are secure.
CAUTION: Attachment, alignment, and delivery of the foot
must be performed by or under the direct supervision of
a qualied prosthetist. Any adjustment or modications
should be done by the clinician and not by the user.
CAUTION: The foot is waterproof to 1 meter; however, if the
foot is submerged, the foot and foot shell should be rinsed
with fresh water and dried immediately to remove salt,
chlorine, or debris.
CAUTION: The foot shell is designed to provide realistic
appearance and maximum performance of the Motion Foot
SLX. The life of the foot shell will depend on level of activity
and degree to which it is protected from wear and damage
with socks and shoes. Socks and shoes should be worn at all
times and should be allowed to dry fully after exposure to
water to prevent damage to the shell.
CAUTION: Patients should inspect the shell daily for signs
of cracks or holes and for the presence of sand or other
debris. If the foot shell shows signs of failure, it should be
replaced as soon as possible to prevent damage to the
carbon ber and soling materials. If debris is present, the
foot and shell should be rinsed and allowed to fully dry.

14
CAUTION: The foot shell may also be cleaned soft cloth and
a soap and water solution or with rubbing alcohol (70%). Do
not use acetone. It will damage the foot shell.
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, local competent authority and Fillauer at the earliest
possible convenience. Clinicians should at any time contact their local
Fillauer representative and local competent authority immediately in the
event of any device failure.
