DEFINITIONS
Mobility chair
A chair designed to meet the comfort and mobility needs of people who
are at risk of falls.
Tilt
A function enabling the seat and backrest to tilt together.
Adjustments
Functions to congure the chair to t different body types.
Patient or user
The chair’s end-user; the person receiving the care.
SAFETY MEASURES
Chair assignment, positioning adjustments and mobilization handling
must be performed by professionals who have been trained for this
purpose. The dynamic design of the chair requires a period of observation
of the user's behavior in the chair. The care team must ensure that it does
not pose a risk to their safety or that of others.
Before using the chair, caregivers must have received adequate training
from an LPA Medical representative or a trained third party. This
instruction manual will be used as a reference for continuing education.
It is strongly recommended to appoint a caregiver responsible
for training and maintaining an up-to-date list of those who have
received training. For the patient’s safety, anyone who has not received
adequate training should not be allowed to use the chair.

6
APPLICATIONS
The Evolution chair is designed primarily for long-term care or to be used
at home for self-sufciency and rehabilitation. It allows patients at risk
of falls to move freely with their legs and arms while sitting in the chair,
reducing anxiety and disruptive behaviors. The Evolution chair can be
an excellent alternative to restraints. It is also used as a comfort chair
to be mobilized by responders, even if the user does not move auto-
nomously. The assignment and initial adjustments must be made by
qualied professionals.
IMPORTANT NOTE:The propulsion wheels are positioned in the center of
the chair, so in the axis of the user’s body. This feature provides intuitive
mobility in space. This often allows patients with cognitive loss to mobilize
the chair without learning.
The Evolution chair is not designed to be cleaned with a pressure
washer or an industrial washing machine. Such practices can lead
to component rust and void warranties. In addition, LPA chairs are
not designed for outdoor use.
The Evolution chair must be used with accessories specifically
designed for it by LPA Medical Inc. It must be used in accordance
with recognized health and safety practices.
INSPECTION BEFORE USE
The chair can be shipped fully assembled or partially assembled. It must
be inspected when unpackaged and you must notify your supplier if
there is any damage or missing parts/accessories so that the situation
is remedied before taking possession.

7
RISK PREVENTION
Always apply the brakes when the wheelchair is not moving and for
any transfer or repositioning maneuver. The same rule applies for an
empty chair.
To prevent the patient from slipping out of the chair, the seat tilt must be
adjusted to an angle appropriate for their condition.
To avoid injury during transfers, be sure that:
• The brakes are applied.
• The patient’s arms are inside the armrests.
• The patient’s legs are positioned in the center of the seat.
• There is no pinch point possible.
• During transfers, the tilt should be fully forward according to the
initial adjustment (see Adjusting the Tilt-in-Space on Page 14 of the
adjustments section).
IMPORTANT NOTE: It is important to observe a user’s behavior while moving
to ensure that they do not pose a risk to themself or to others.
These measures are necessary for the safety of both the patient and the
caregiver. Using the tray for restraint purposes is prohibited and may
result in possible strangulation that could cause death. Only the use of
approved and prescribed restraints is acceptable.
Note: Contact us for more information about the installation of positioning
straps.

8
IMPROPER USES
• Manipulating the chair without proper training.
• Wheeling the chair outside of designated areas.
• Using it for a patient without assignment or adjustments made by
a professional.
• Making adjustments that require frequent repositioning.
• Transferring a patient without using the tilt function.
• Leaving a patient in an unsafe area or without supervision.
• Using it as a shower chair.
• Exceeding the recommended weight limit.
• Allowing a patient to stand without storing the footrests or without
applying the brakes.
• Moving the chair without releasing the brakes.
CLEANING
Follow the selected covering manufacturer’s recommendations for cleaning.
Check with your supplier that the products you use are compatible.
The chair should not be pressure-washed or placed inside a washing
machine. These practices may cause the chair components to rust
internally, as well as deteriorate the adjustment components, thus
voiding the LPA chair warranty.
MAINTENANCE
For optimum use of the chair, keep it clean and the components properly
adjusted. Vinyl coverings should be cleaned with products recommended
by the manufacturer. The exterior metal parts of the chair should be
cleaned as needed, using the same solution as for the coverings.
As long as the recommendations for use and cleaning are followed, the
Evolution chair does not require any preventive maintenance. Some parts
will need to be replaced due to normal wear and tear over years of use.

SEAT/FLOOR HEIGHT
1. Determine if the seat needs to be
raised or lowered.
2. Tip the chair backwards until the
push bar rests on the oor.
The height adjustment (from 16"to 21") is done according to the length
of the user’s lower leg. It is important to have hips, knees and ankles at
90 degrees. The patient’s feet must make good contact with the oor.
3. Using a ½" (13 mm) wrench,
remove the 4 bolts (2 per side)
that hold the seat support.
4. Position the seat bracket at the
desired height. MAKE SURE BOTH
SIDES ARE AT THE SAME LEVEL.
Put back the 4 bolts without
forgetting the at washers and the
lock washers. Tighten properly.
5. Put the chair back on its wheels and have the user try it, to ensure that
the feet have sufcient contact with the ground for self-movement.
Readjust if needed.
ADJUSTMENT AND OPERATING
INSTRUCTIONS

11
WARNING: THE CHAIR MUST BE UNOCCUPIED WHEN MAKING THIS
ADJUSTMENT.
SEAT DEPTH
1. Determine if the backrest must
slide forward or backward to
provide the appropriate clearance
behind the patient’s knees.
2. Lay the chair on its side.
3. Using a ½" (13 mm) wrench,
loosen the 4 bolts under the seat
structure that go through the slots
and that control the seat’s depth.
WARNING: DO NOT REMOVE THEM
ALL THE WAY.
4. Adjust the backrest to the desired
position by sliding both sides
at the same time so that the
backrest moves uniformly.
The seat depth adjustment (from 13 ¾"to 18") is done according to
the length of the user’s leg. It is important that the hollow in the back of
the knee (the popliteal fossa) has proper clearance. Adjust the depth
of the seat so that your hand easily passes between the knee and the
seat cushion. This adjustment will promote good contact with the seat
and the back with the backrest.
5. When the appropriate depth is
reached and equal on both sides,
rmly tighten the 4 bolts.
6. Get the user to try it and readjust it if needed.
Slide the backrest forward or backward to adjust the seat depth.

WARNING: THE CHAIR MUST BE UNOCCUPIED WHEN MAKING THIS
ADJUSTMENT.
For this operation, it is highly recommended to lay the chair on its side
for easier maneuvering and to reduce the risk of nger jamming.
1. Determine in advance the
backrest tilt adjustment required.
2. Apply the brakes, hold the chair on
both sides and lay it on its side.
3. Under the seat behind the chair,
nd the series of 4 holes in an arc
pattern that control the backrest
angle. Using a ½" (13 mm) wrench,
remove the bolts on each side.
12
SEAT/BACKREST ANGLE

4. Push or pull on the top of the
backrest to change its angle.
6. Get the user to try it and
readjust if needed.
The backrest angle can be adjusted from 91 to 115 degrees to accom-
modate the shape of the user’s back. Adjust the backrest tilt for
a comfortable position supporting the lower back and head and to
provide the patient with a clear eld of vision in front of them. This
posture will allow for periods of rest in the chair.
5. Line up the holes and bolt the
backrest at the desired angle.
Don’t forget the lock washers.
BE SURE TO USE THE SAME HOLE
ON EACH SIDE.
13
SEAT/BACKREST ANGLE (continued)

14
The seat’s tilt can be adjusted depending on the user’s needs. By varying the
position of the gas cylinder on the multi-hole bracket, you can obtain:
A. Signicant assistance standing up.
B. Slight assistance standing up.
C. A backward tilt.
TILT-IN-SPACE
WARNING: THE CHAIR MUST BE UNOCCUPIED WHEN MAKING THIS
ADJUSTMENT.
For this operation, it is strongly recommended to lay the chair on its side
for safer maneuvering to minimize the risk of jamming ngers. It will make
the operation easier.
A B C

15
TILT-IN-SPACE (continued)
1. Determine in advance the
backrest tilt adjustment required.
2. Apply the brakes, hold the chair on
both sides and lay it on its side.
3. Remove the locking pin from
the multi-hole bracket behind
the backrest.
4. Reposition the gas spring in
the correct place, then reinsert
the locking pin and secure it with
the wire snap.

16
TILT-IN-SPACE (continued)
5. Place the chair upright, then check
the tilt’s full travel by activating
the gas spring and letting the seat
raise completely. Then, activate
the gas spring and lower the seat
completely by applying your
weight on the push bar. Ensure
that the control cable remains
free at all times and isn’t pinched
anywhere.
6. Get the user to try it and readjust
if needed.
The chair is equipped with tilt-in-space that can be adjusted to any angle
from 0 to 23 degrees by using the multi-hole bracket behind the chair’s
backrest. The caregiver activates the tilt by using the lever located on
the right side of the push bar. It is recommended to tilt the chair forward
to facilitate transfers while the patient is sitting/standing and for a more
upright posture while eating. Tilting the chair backwards is recommended
to change the patient’s position every 30 minutes to maintain skin
integrity and increase postural control (resting position).

17
1. Use a ½" (13mm) wrench
to remove the bolt securing the
armrest on each side of the seat.
ARMREST HEIGHT
2. Position the armrest at the
desired height and replace the
bolt, without forgetting the at
washer and the lock washer.
3. Adjust both sides the same way.
Adjust the armrest height from 6"to 9 ¾"depending on the length of
the user’s arm. Adjust the armrest height so that the user’s forearms
are supported (elbows at 90 degrees) to relax their shoulders.

7/16
18
Height adjustment
1. Determine the height required for
the lateral supports.
2. Using a 7⁄16" (11 mm) wrench,
loosen the 4 nuts slightly from the
trunk support attachment, without
removing them completely.
Note: hold the assembly with
your free hand so that it doesn’t
fall suddenly.
3. Position the lateral supports
at the desired height. Retighten
the nuts.
4. Get the user to try it and readjust,
if needed.
Use the brackets behind the backrest to adjust the trunk support height
so that they are positioned under the user’s armpits. It is important to
allow a space of three ngers under the armpits to prevent blocking
blood circulation under the user’s arm.
LATERAL SUPPORTS – OPTIONAL

19
Width adjustment
LATERAL SUPPORTS – OPTIONAL (continued)
1. Determine if the lateral supports
must be widened.
2. Using a 1⁄8" Allen key, loosen
the adjustable lock’s two screws
without removing them completely
so that you can adjust the width.
3. Adjust the lateral supports to
the desired position.
5. Get the user to try it and readjust
if needed.
Adjust the lateral support width using the locks on the lateral support pads
behind the backrest so that you can slide the thickness of a hand easily
between the user’s trunk and the pad on each side. These adjustments will
ensure that the user’s trunk posture is better aligned against the backrest.
4. Re-tighten the screws. Repeat the
procedure on the opposite support.

20
USING THE FOOTRESTS – OPTIONAL
1. Press on the black lever on the
footrest assembly and swivel the
assembly 180 degrees outward,
until the footrest locks into place
(you will hear a click).
2. Lower the footrest.
3. Repeat the operation on the
other side.
4. To store the footrest, raise the
footrest upward, activate the
black lever and pivot the footrest
inward until it locks into place.
Footrests are optional on the Evolution chair. It is recommended to
use them when the chair is pushed by others to prevent injury to the
lower limbs.
