the patented breakthrough to prevent sliding and pressure ulcers The Ophir Cushion has been in clinical use for over three years and has elicited a great deal of positive feedback and recommendations from professionals and end users in the field. It has been reported that the pressure ulcers, plus the Ophir Cushion is very comfortable which reduces unrest and relaxes those sitting on it. The Ophir Cushion provides wheelchair users the perfect, high-quality, professional solution for preventing pressure ulcers and sliding. The Ophir Cushion is built from the highest quality materials. The cushion’s clever construction uses high quality, high density, viscoelastic memory foam. It allows comfortable,safe and stable seating and optimal dispersion of pressure to prevent pressure ulcers and sliding in wheelchairs.

Preventing slipping and pressure wounds
in a wheel chair

BackgroundBackground::
• Millions of disabled people around the
world with various degrees of
disabilities are confined to wheel chairs.
• The less control they have of their
seating position – more likely they will
develop pressure wounds and other
pathologies.
(Ulcer ,Decubitus)

3. ‫שמורות‬ ‫הזכויות‬ ‫כל‬ -"‫פיזיותרפיה‬ ‫"מעיין‬3
BackgroundBackground
• A common event we encounter working with disabled
people, is the gradual slipping down in the wheel chair
due to lessened/lack of control of the lower body.

4. ‫שמורות‬ ‫הזכויות‬ ‫כל‬ -"‫פיזיותרפיה‬ ‫"מעיין‬4
BackgroundBackground
Slipping down -
•Causes great discomfort
•Hinders patients activities
• Leads to a “slump position” – Increases pressure on
the Sacrum and increase risk of pressure wounds.
• Increases Kyphosis, hindering chest expansion which
leads to a decrease in breath Efficiency and ventilation.
• Increases friction and shear forces on soft tissues
which may result in pressure wounds -even more so with
patients who suffer from bad/lack of bladder control

BackgroundsBackgrounds --
• Some patients do not suffer from any physical
disability but have a cognitive dysfunction which
may results in unawareness of their sitting
position .
• Coupled to a physical disability the
problem increases exponentially.

Background -Background -
As the angle between pelvis and back seat increases we witness –
An increase in the distance between back and back seat.
An increase of torque leading to slipping and increase in shear forces
operating on soft tissues.
OUR GOAL –Preventing slipping in the wheel chair.

7. ‫שמורות‬ ‫הזכויות‬ ‫כל‬ -"‫פיזיותרפיה‬ ‫"מעיין‬7
The Solution must address two
major issues:
• Friction – which will prevent slipping
• Pressure dispersion– which will decrease risk of pressure
wounds
Meticulous market research have shown that
there is no “reasonably priced” solution.
A problem which especially affects
medium/large scale institutions.

A manager’s DilemmaA manager’s Dilemma
• “With decreasing and strict financial
budget should I purchase
expensive cushions for the
selected few or buy cheap, low
grade cushions for the Majority”.

OFIR Seat CushionOFIR Seat Cushion
• Creates proper slope and anchoring of the
pelvis in the seat of the wheel chair by
using two surfaces.
• Hard foam – located in the front of the
cushion ,preventing skidding
• Soft foam - located in the back of the
cushion, dispersing pressure

11. ‫שמורות‬ ‫הזכויות‬ ‫כל‬ -"‫פיזיותרפיה‬ ‫"מעיין‬11
Thickness Optimization
• In designing the cushion ,one needs to balance a few factors
• Thicker foam – Positive effect
Increases effectiveness preventing pressure wounds.
• Negative effects -
Cost - Using more foam increases the product’s price.
Physical difficulties -A thicker cushion increases the care
giver’s difficulty in placing the patient.
A change in the height ratio between the back seat/handles and
cushion may Lead to instability and discomfort.
• Careful research have shown that optimum
cushion’s height is 8.5cm (10cm in the thigh
area).

Pressure dispersionPressure dispersion
comparisonscomparisons::
• Compared to current leading products “OFIR Cushion”
was found to be more effective* in Pressure dispersion
due to-
• Use of high quality materials.
• Extra dense Visco Elastic foam.
• The following is an XSensor imaging of
“OFIR Cushion” compared to other products
*The comparison was made only on one patient thus
cannot be published as valid research.

In ConclusionIn Conclusion
• OFIR Cushion is highly cost effective and
will improve both patients health and
quality of life.
• In addition to decrease of potential work
load of care giver’s, it is the best available
comprehensive solution for medium/large
institutions.

Guidelines and limitationsGuidelines and limitations
• The Cushion might not prevent slipping due to
Increased Extensor Tone - In this case we
advise a Tilt in Space solution.
• The Cushion’s effectiveness preventing slipping
may decrease in chairs with low foot rest –
When knees are below seat’s height.

21. ‫שמורות‬ ‫הזכויות‬ ‫כל‬ -"‫פיזיותרפיה‬ ‫"מעיין‬21
Guidelines and limitationsGuidelines and limitations
• Low quality of back rest may result in patients
slumping into a kyphotic position and PPT.
• Solution – a back lumbar pillow which increases back
EXT and Anterior Pelvis Tilt (APT) - Thus decreasing
weight load of the buttocks moving it toward the thighs.
• A back lumber pillow can be purchased in addition to
“OFIR Cushion”.
