The purpose of a ROHO cushion is to decrease the amount of pressure on the sitting area through patented technology of interconnected neoprene air cells that increase and decrease in air volume to match an individual’s contours.
Comparison of Three Wheelchair Cushions for Effectiveness of Pressure Relief
Hon Keung Yuen, Donna Garrett – AJOT
Objective: To compare the effectiveness of the shortterm pressure-relieving ability of the three most commonly prescribed wheelchair cushions (Roho, Jay, Pindot) for a person with SCI
Conclusion: The Roho cushion was more effective in relieving pressure at the seating surface than the Jay and Pindot cushions.
Inflating and Adjusting Standard ROHO Cushion
- Place cushion on centered in a chair, with air cells faced up, the valve in the front-left corner of the user.
- Turn valve counter-clockwise to open.
- Slide pump’s rubber nozzle over the cushion valve and inflate the cushion until it begins to slightly arch upward.
- Pinch the pump’s nozzle while turning the valve clockwise to close.
- Remove pump.
- Have the user sit in the chair on the cushion in their normal sitting position, making sure cushion is centered underneath.
- With a plastic bag, form a mitten around your hand to slide it (and the plastic bag) between the cushion’s surface and the user’s bottom. Lift their leg slightly and feel for their lowest bony prominence (compare also between the left and right buttocks as well). Lower the user’s leg back to the sitting position.
- Turn the valve counter-clockwise to let the air until the user feels comfortable OR if using your hand method, release air until you can barely move your fingertips – no more than 1 inch and no less than 1/2 inch.
- Turn valve clockwise to close.
Inflating Quadtro ROHO Cushion
- Place the QUADTRO ROHO cushion in the wheelchair with the air cells facing up and the non-skid surface of the cover facing down.
- Before inflating, you must open the ISOFLO Memory Control so that all of the air cells will inflate. Push the ISOFLO green knob toward the unlocked position.
- Slide the rubber nozzle of the hand pump over the inflation valve. Pinch the nozzle, turn to open the inflation valve, and overinflate the air cells.
- Have the individual sit in the chair in their usual position. The cushion should be centered beneath the individual.
- (Perform a hand check) Slide your hand between the cushion and the individual. Lift the leg slightly and feel for the lowest bony prominence, and then lower the leg to a sitting position. Leaving your hand in this position…
- Open the valve to remove air, keeping your hand beneath the individual’s lowest bony prominence.
- Release air until you can slightly move your fingertips, then close the valve.
— If you can slightly move your fingertips: the cushion is at the Proper Cushion Inflation Setting (½” – 1” air between the lowest bony prominence and the seat surface) and no further adjustment is needed.
— If you can easily move your fingertips: there is too much air between the lowest bony part prominence and the seat surface. Open the inflation valve and slowly release air until you can barely move your fingertips, then close the valve.
— If you cannot move your fingertips at all: there is too little/no air between the lowest bony prominence and the seat surface. Open the inflation valve and slowly add air until you can slightly move your fingertips, then close the valve.
