Back Cushion
Tilt-in-Space
Optimally, position the firm seat back at 90
degrees to the sitting surface is needed to en-
sure maintaining a neutral pelvis. A soft back
encourages slouching. A reclined back
encourages a posterior pelvic tilt.
Tilt-in-space
of the entire seat in
space will assist the child’s
muscular trunk control against
gravity. If it is too erect, he may
slump. If too far back, he may pull
forward to become more erect. It is
important to position the child as
erect as possible to encourage the
child to develop the strength and
balance necessary to improve.
When necessary, tilt the child back
for support, but always be ready to
enable the child to challenge
gravity.
