CMC Wheelchair Seating & Positioning

Question 1

What is the primary goal of proper wheelchair seating and positioning?

Accepted Answer

To maximize function, comfort, and prevent secondary complications

Answer

Proper seating and positioning maximizes the user's functional ability, prevents pressure injuries, manages postural deformities, and enhances comfort and quality of life.

Question 2

What is a pressure mapping assessment used for in wheelchair seating?

Accepted Answer

To identify areas of high pressure that could lead to pressure injuries

Answer

Pressure mapping uses sensor technology to visualize pressure distribution at the seating interface, helping clinicians identify high-pressure areas and select appropriate cushions.

Question 3

What does the term 'pelvic obliquity' refer to in seating assessment?

Accepted Answer

A lateral tilt of the pelvis where one side is higher than the other

Answer

Pelvic obliquity occurs when one side of the pelvis is higher than the other in the frontal plane, often requiring accommodation or correction in the seating system.

Question 4

Which cushion type is most effective for pressure redistribution in high-risk users?

Accepted Answer

Air flotation or hybrid cushion systems

Answer

Air flotation and hybrid cushions (combining air, foam, and gel) provide superior pressure redistribution by conforming to the user's body shape and distributing weight more evenly.

Question 5

What is the significance of seat-to-back angle in wheelchair positioning?

Accepted Answer

It affects posture, respiratory function, and pressure distribution

Answer

The seat-to-back angle significantly impacts the user's posture, respiratory capacity, ability to perform functional tasks, and pressure distribution across the seating surface.
