Question 1

A client with ALS is transitioning from manual to power mobility. Which power wheelchair drive wheel configuration is preferred when trunk control is declining but upper extremity function remains?

Accepted Answer

Mid-wheel drive

Answer

Mid-wheel drive power wheelchairs offer the tightest turning radius, which is advantageous for indoor navigation as trunk control declines.

Question 2

When fitting a client with a tilt-in-space manual wheelchair, what is the primary therapeutic goal of tilt?

Accepted Answer

Pressure redistribution off ischial tuberosities without changing hip angle

Answer

Tilt-in-space shifts the weight-bearing surface without changing the hip flexion angle, effectively redistributing pressure from the ischials.

Question 3

A CMC consultant is assessing a van conversion for a client with high-level SCI who drives from their power wheelchair. Which feature is mandatory for safe driving position?

Accepted Answer

Certified WTORS (Wheelchair Tie-Down and Occupant Restraint System) compliant securement

Answer

WTORS-compliant tie-down and occupant restraint systems are mandatory to safely secure the wheelchair and protect the driver in a crash.

Question 4

Which caster wheel size is best suited for a manual wheelchair user who frequently navigates outdoor uneven terrain?

Accepted Answer

5-inch pneumatic casters

Answer

Larger pneumatic casters absorb shock and roll more easily over uneven outdoor surfaces compared to smaller hard casters.

Question 5

A driver with right hemiplegia needs to operate a vehicle safely. Which adaptation addresses steering with one functional hand?

Answer

A spinner knob allows single-hand steering control, enabling the driver to turn the wheel fully with their functional hand.
