Now a
standard feature on every Viking 4 X 4 is the tilt feature
for pressure relief.
Free
Tilt versus recline is an old
debate that has reemerged as new products, theory, and
clinicians have entered the field of positioning. In
general, a trend toward more tilt-in-space system
recommendations versus recline system recommendations is
evident. More specifically, many facilities recommend
almost solely tilt or solely recline systems. Are we in a
rut? Is this because of a lack of knowledge of the
options? Do valid reasons exist for such exclusivity? The
difference appears to be because of the patient population
and primarily involves conditions, age, and living
situation.
This article will discuss why certain facilities tend to
lean toward one option or the other. The article will
present indications and contraindications for each system,
including typical conditions and age ranges for each.
Finally, the article will clarify when and why to consider
each option for a client. This cannot be a "cookbook"
approach; a qualified seating specialist must weigh many
factors.
Most of us change our positions throughout the day. We sit
up tall and tuck our feet under our chairs for awhile and
then we slouch and stretch our legs out. Not doing so
leaves you feeling like you just sat through a double
feature at the theatre. Tilt systems (which change a
person's orientation in space while maintaining fixed hip,
knee, and ankle angles) and recline systems (which change
a person's seat-to-back angle) have traditionally been for
clients requiring pressure relief. Today, these systems
are useful for many more reasons.
Tilt Systems
A tilt system provides a change of orientation and thus
redistributes pressure from one area (e.g., the buttocks
and posterior thighs) to another area (e.g., the posterior
trunk and head) and maintains physical angles at the hips,
knees, and ankles.
Indications
To distribute pressure to reduce risk of pressure sores,
increase comfort, and increase sitting tolerance.
To elicit extensor tone. Maintaining the physical angles
can inhibit muscle tone, and increasing the seat-to-back
angle often elicits extensor tone.
To maintain posture. Changing the physical angles can lead
to a loss of posture that one cannot regain by reducing a
recline mechanism, and sometimes the client must be
removed and repositioned after reclining.
To prevent sheer. No matter what the brochure says, all
recline systems have some sheer that causes friction or
dragging of the tissues, particularly on the posterior
trunk. This is particularly important in an intimate
seating system such as a molded seat. The components may
move out of position during recline. Have you ever sat in
the dentist chair while reclining, and your head fell off
the head pad? Your body was no longer in alignment with
the components of the dentist chair.
To maintain proper position of related devices such as a
communication device, computer, and access switches. This
can include the powered wheelchair access method as well.
To maintain a fixed seat-to-back angle. Some seating
systems are one-piece systems (e.g., the sitting support
outhouses) and cannot accommodate a change in seat-to-back
angle.
When range-of-motion limitations prohibit a recline
system, such as hip flexors, hamstrings, or even
heterotypic ossification.
