P.S.I.S.
10 o -15 o Angle
The effect of back support and the angle of the backrest
are interconnected. Changes to one often requires
change to the other if optimal support and balance are to
be achieved. Use of a wheelchair with adjustable ten-
sion upholstery can significantly increase function, pos-
tural condition, balance and comfort.

The height of the backrest and the amount of control
provided by the adjustable tension upholstery will vary
depending on the abilities of the user. An active paraple-
gic (SCI) may require minimal back height which adds
posterior stability to the pelvis and lets the trunk assume
a natural balance over the top edge of the wheelchair
upholstery. A less active para (with a higher level of in-
jury) or a quadriplegic may require a higher backrest with
an increased level of recline (FIGURE 9).

cure the two (2) back canes to the wheelchair frame.
