Which ambulation aid typically provides the greatest base of support for a patient with balance deficits: a cane or a walker, and why?

• A. Cane
• B. Walker
• C. Crutches
• D. Stair lift

Answer: (B)

The main idea is maximizing base of support to improve stability when balance is a concern. A walker provides the greatest base of support because it has four points of contact with the ground (the front and rear legs), creating a wide frame around the user. This wide stance lets the user push through the arms and torso while keeping the feet well within the base, reducing sway and supporting more secure weight bearing.

A cane offers only one contact point, narrowing the base and relying more on trunk control and arm support, which is less stable. Crutches provide two points of contact but still create a narrower base than a walker and require more coordination. A stair lift isn’t an ambulation aid used for steady balance on level ground; it’s for moving between floors and doesn’t provide a walking base of support.
