CREATING A SILHOUETTE
16. Record the back and seat shape by pulling the
imprinting handles across the data panels. Pull
C
each imprinting handle only once. A baseline and
R

a contour line should now be printed on each data
A
T
form. If the base line was not recorded, it can be
I
N
taken once the client transfers out of the Shape
G
Sensor.

Cushion length. Retract the back sensor lever

face to the place on the clients thighs that the cush-

houette seat cushions are produced with a
rounded rear section that allows them to be fully
inserted into the wheelchair with minimum inter-
ference from the back push handles. Issues such
as the clients activity level and propulsion method
should be taken into account when determining
the cushions length. If the client has their knees
pulled into a tucked position for improved maneu-
verability then the cushion may be quite short. If
the client propels using their lower extremities then
clearance should be provided for the calf to allow
sufficient movement rearwards. Lengths can be
produced from 8"-22".

Back height. The individuals back height is de-
pendent upon activity level and the need for pos-
tural support. There is no magic rule for determin-
ing back height. In order to promote upper extrem-
ity function the scapula area should be free from
interference. This can be accomplished by stop-
ping the back height below the scapula or flatten-
ing the area behind it. The number printed on the
back grid is used to determine back height (Fig-
ure 11). Do not measure the back height with a
tape measure, but write down the number printed
on the front of the back sensor grid.
Leg length. This measurement is taken to help
determine footrest height and desired floor to seat
height. This is especially important for individuals
who propel using their feet or who transfer using
the stand and pivot technique.
Back Angle. The back angle measurements are
printed on the side of the back sensor panel.
Tilt Angle. The tilt angle can be taken using an
inclinometer or bubble level. This angle will assist
with setting up the clients finished system.
WARNING
When returning the client in the Shape
Sensor to the full upright position, more
body strength will be required for ap-
proximately the last twenty (20) degrees
of incline (reverse recline). Make sure
to use proper body mechanics (use your
legs) or seek assistance to avoid injury.
18. Transfer the client off of the Shape Sensor and
position them in their own wheelchair. Make sure
the back sensor panel is locked before the trans-
fer, and that the client is supported properly and all
belting/strapping is secured in their chair.
19. Remove the data panels from the imprinters.
The data panels have a flexible strap to assist with
their removal. Make sure the imprinters are all of
the way to one side to allow the panels to be pulled
out of their channels.
20. Remove the data forms from the panels and fill
in the requested information on each section (date,
dealer name and number, client name, contact
person, and phone number)
21. Copy the Shape Sensor's serial number onto
the order form. There is a separate serial number
for the back and seat. This is a very important
step! Each Shape Sensor has its own "personal-
ity" that assists in fabrication and this is recorded
by Invacare in their computer system. The cush-
ions can not be produced without this number.
