Which device is most appropriate for providing stability when the user has good upper-extremity strength?

• A. Cane
• B. Crutches
• C. Wheelchair
• D. Walker

Answer: (D)

Stability in gait hinges on how broad and controllable your base of support is. A walker provides the widest base—the frame and four points of ground contact give the greatest resistance to tipping and wobble. With good upper-extremity strength, you can confidently push the walker forward, using your arms to help maintain upright posture and control as you step, which maximizes stability during ambulation. A cane offers only a single contact point and a narrower base, which is less stable. Crutches increase base width but demand more balance control and arm effort, which can be harder if balance is a concern. A wheelchair is for seated mobility and does not provide the same upright stabilization during standing or walking. So, when the user has strong arms, the walker best supports stability.
