Walkers, or mobility walkers as they are sometimes called, help individuals who have trouble maintaining their balance while walking. Walkers are frequently used by the disabled and the elderly as well as by younger adults and children who suffer from diseases like multiple dystrophy.
The design used to manufacture walkers has remained pretty much the same about one foot deep, around waist height and slightly wider than an average size body. The user simply holds onto the sides of a walker, picks it up and places it in front of him as he moves forward. The walker helps maintain balance and stability as an individual moves forward.
