Which of the following statements regarding pelvic positioners is TRUE?

• Pelvic positioners are primarily used to prevent falls from a wheelchair

• Pelvic positioners are designed to stabilize the patient’s pelvis in a proper position

• Pelvic positioners are typically made of metal and rigid straps

• Pelvic positioners prevent all lateral and anterior movements of the pelvis

• Which of the following materials are pelvic positioners usually made from?

• • Leather and metal clips

• • Elastic bands with zippers

• • Velcro straps or buckles

• • Plastic braces with screws

• What is the primary function of caster wheels on a wheelchair?

• • To stabilize the patient’s pelvis in a proper position

• • To prevent the wheelchair from tipping backward

• • To keep the wheels in alignment for straight movement

• • To allow the wheelchair to turn

Which of the following describes a benefit of pneumatic caster wheels?

• 1. Narrower in design to reduce weight of the wheelchair

• 1. Easier to maintain compared to solid rubber wheels

• 1. Provide better shock absorption and are ideal for outdoor use

• 1. More durable on smooth indoor surfaces

Why are solid rubber caster wheels preferred for indoor use?

• 1. They are easier to maintain compared to pneumatic wheels

• 1. They provide better shock absorption for uneven surfaces

• 1. They are less likely to fall into cracks

• 1. They are wider and better for turning on rough terrain

Which of the following statements about pneumatic caster wheels is TRUE?

• 1. Pneumatic wheels are ideal for indoor use due to their narrow width

• 1. Pneumatic wheels provide better shock absorption than solid rubber wheels

• 1. Pneumatic wheels require no maintenance compared to solid rubber wheels

• 1. Pneumatic wheels are smaller in size to improve turning efficiency

Which of the following statements about drive wheels on a wheelchair is TRUE?

• 1. Drive wheels are only operated with electrical assistance.

• 1. Drive wheels are primarily used for turning the wheelchair.

• 1. Drive wheels are used for propulsion and can be pneumatic or solid rubber.

• 1. Drive wheels are located at the front of the wheelchair for stability.

What is the function of the outer rim on wheelchair drive wheels?

• 1. It is used for gripping and propelling the wheelchair

• 1. It stabilizes the wheelchair during turns

• 1. It helps absorb shock on uneven terrain

• 1. It prevents the wheel from slipping on smooth surfaces

Which of the following is a modification on the outer rim of drive wheels for patients with a weak grasp?

• 1. A rubberized grip for shock absorption

• 1. A motorized attachment for reduced effort

• 1. Projections on the rim for easier propulsion

• 1. A narrower rim to reduce hand strain

A wide/long wheelbase (drive wheel to caster wheel) has:

• Increased stability; Decreased maneuverability

• Decreased stability; Increased maneuverability
