Which device is the most stable unilateral assistive device?

• A. Quad cane
• B. Single point cane
• C. Hemi-walker
• D. Forearm crutch

Answer: (C)

Stability in an assistive device depends on base of support and how many points of contact with the ground the device provides. The more contact points and the wider the base, the more stable the device will feel for someone using it on one side. A hemi-walker is designed for unilateral use but functions like a walker by giving multiple ground-contact points on the supported side, creating a larger, multi-point base. This setup distributes weight better and resists tipping more effectively than other unilateral options, such as a single-point cane or a forearm crutch, which offer fewer contact points. A quad cane does have a broad base but remains a cane and cannot offer the same stability as a device that mimics a walker’s multi-point support. So the hemi-walker provides the greatest stability among unilateral devices.
