If you have difficulty balancing or you're at risk of falling, a walker can make it easier for you to get around — whether you use the walker temporarily or as a permanent aid.
If stability is a significant concern, you might choose a standard walker without wheels — which you must pick up to move. Many people, however, choose between two-wheel and four-wheel walkers.
A two-wheel walker allows you to place weight on the walker as you move. The legs with wheels allow you to easily push the walker forward, and the legs without wheels prevent the walker from rolling while you're stepping forward. If you don't need to lean on the walker for balance, you might be able to walk faster with a four-wheel walker.
