Which device cannot be used if non-weight bearing?

• A. Forearm crutch
• B. Quad cane
• C. Axillary crutch
• D. Walker

Answer: (B)

Non-weight bearing means the injured leg must not bear any load, so the assistive device used should transfer most of the body's weight through the upper limbs and trunk rather than through the leg. Forearm crutches, axillary crutches, and a walker all provide multiple contact points and enable the patient to offload the injured leg safely. A quad cane, while it offers a broader base for balance, is still a cane that relies on a single upper-limb support. It provides less stability and can make it harder to keep the leg completely off the ground without inadvertently loading it. For that reason, a quad cane is not appropriate for non-weight bearing ambulation.
