Which braking system requires coordinated motor ability to operate push or pull brakes?

• A. Toggle/lever brakes
• B. Planar lateral supports
• C. Chest strap
• D. No armrests

Answer: (A)

Braking mechanisms on wheelchairs rely on the operator’s ability to control movement with the hands. Toggle or lever brakes require you to push or pull a lever with coordinated finger, hand, and forearm action to engage and release the brake. That coordination is necessary to apply the brake smoothly while manipulating the chair, especially at different speeds or on uneven surfaces.

The other options are not braking systems. Planar lateral supports are seating aids for stability, a chest strap is a restraint, and having no armrests doesn’t provide a braking mechanism. So the one that truly requires coordinated motor ability to operate by pushing or pulling is the toggle/lever braking system.
