9. Transfer the client onto the Shape Sensor.
Please refer to the section regarding transfers
(Page 13) to assist with this important step.
10. Orient the client on the Shape Sensor's seat.
This orientation process requires that the clinician
have a strong background in seating/positioning
and that a thorough mat evaluation was performed
(Figure 6). It is suggested that the following guide-
lines be used with the understanding that each
person is unique and there are always exceptions.
FIGURE 6 POSITIONING THE CLIENT ON THE
Center the client on the Shape Sensor so that
an equal amount of cushion shows on both sides.
Asymmetries of the client may not allow for equal
space on both sides.
Check pelvic tilt and position the client with a neu-
tral to slightly anterior orientation. Use your thumbs
and forefingers of each hand to gently hold the cli-
ents pelvis. The need for excessive force to posi-
tion the pelvis may require that smaller adjustments
be made. A neutral to anteriorly tilted pelvis can
assist with spinal extension and reduced
kyphotic posturing.

SYSTEM
SEAT
Check for pelvic obliquity. Accommodate if fixed,
andcorrect if flexible.
Check for rotation of the pelvis and trunk. De-
rotate if the forces are not excessive and improved
posture is realized. An apparent leg length dis-
crepancy may actually be rotation of the pelvis.
Set the footrest height so each thigh is level and
at the same height. The footrest height can also
control the depth of the leg channels and influences
clearance under tables.
Position the lower extremities in the desired
amount of ab/adduction taking into account the limi-
tations of the wheelchair frame and the therapeu-
tic benefits of the posture. Increased abduction
can mean a more stable posture, but may exceed
the overall width of the clients chair.
Adjust the armrests to help support the upper
extremities and trunk. Be careful to not elevate or
depress the shoulder girdle.
11. Orient the client to the Shape Sensor back.
WARNINGS
ALWAYS engage both wheel locks while
changing the orientation of the Shape
Sensor modules.
When adjusting the seat depth, make
sure the adjustment knobs are securely
locked in place.
To maintain stability and safety, make
sure the client is properly positioned in
the Shape Sensor before reclining or in-
clining (reverse recline).
When adjusting the back angle, DO NOT
remove back angle adjustment knobs
as they help secure the back sensor to
the frame.
Adjust the seat depth with the clients pelvis ori-
ented to the desired tilt and the thighs fully sup-
ported. Do not cause posterior pelvic tilt by over-
extending the seat depth. If there is a significant
amount of thigh that remains unsupported, even
with the seat depth set to the maximum amount,
then the remaining surfaces can be produced at
the factory by extrapolating the cushions shape
forward. This will be covered more fully in the "mea-
surements" section.
Adjust the back angle for the desired comfort
level and to accommodate any limitations of move-
ment. The head should be balanced over the
