Which option does not require any UE or trunk support?

• A. Planar lateral supports
• B. No armrests
• C. Fixed/non-removable armrests
• D. Toggle brakes

Answer: (B)

The idea here is how different wheelchair features interact with the need for upper-extremity or trunk support. Planar lateral supports provide side stabilization for the trunk, and fixed/non-removable armrests give a place to rest the arms, both of which reduce the active demand on the user’s trunk or arms. Toggle brakes are operated by the upper limbs, so they inherently involve UE use. Having no armrests means there’s no built-in means for the user to rely on arm support from the chair. In that case, the feature itself does not require the user to provide UE or trunk stabilization through an armrest. The other options all involve some form of external support or a control that requires upper-extremity action. Therefore, the option with no armrests does not require UE or trunk support.
