SPECIAL SEATS AND WHEELCHAIRS
Healthy, comfortable, and functional positions
Whether or not a chair has wheels, the position in which it allows a child to sit is
very important. (See Chapter 65.)
For most children, the chair should help them to sit more or less like this:
591
back straight
hips in
straight line
with the back,
against the
back of the
chair
legs at a
right angle
to the back
looking ahead
(not tilted
back or down)
knees at a
right angle
ankles at a
right angle
feet firmly
supported
head evenly
centered
(not tilting
to one side)
shoulders
even
knees somewhat
separated
ankles and feet
separated
body straight
and centered
above hips
hips centered
legs straight
down
feet supported
at right angles
to the body (not
tilted in or out)
CAUTION: The seat should be wide enough to allow some free movement
and narrow enough to give needed support (see Measurements, p. 602).
Common seating problems and possible solutions
Problem: Hips tilt back
In children with
spastic cerebral
hips palsy the hips often
tilt stiffen backward.
back This triggers spasms
that straighten the
legs and cause other
muscle tightness
with loss of control.
Also, children with weak hips
or back, from spinal cord injury,
spina bifida, or severe polio,
often sit slumped with their
hips tilted back and the back
severely curved. This can lead
to permanent deformity.
One of the most common causes
of backward tilting hips is
a chair like this one that is
too big for the child.
Other causes of backward
tilt and bad position are:
A good position can often
be gained through:
a chair back
that tilts
far back
BAD
and a cloth
back that
sags.
These let the
child lean
back and
cause the hips
to slip forward.
Also,
footrests
that
are
far forward so that knees
do not bend enough can
Increase spasticity that
tilts hips back
a fairly stiff,
upright back at
a right angle
to the seat.
a chair that
fits the child
so that his
hips reach the
chair back.
GOOD
the knees at right
angles, and feet
firmly supported.
BETTER
Most children,
and especially
a child who
tends to fall
forward in
his seat, will
sit better and
more comfortably if the
whole chair tilts back
a little. But be sure to
keep right angles at
hips, knees, and ankles.
To tilt the chair back, the rear wheel mount can be moved higher up.
You may also need to move the wheel mount back farther to keep
the chair from falling backward when going uphill. Be sure the front
caster barrel is still straight up or making turns will be harder.
