A wheelchair is a wheeled mobility device in which the user sits on and is able to be mobile. The device is propelled either manually (by turning the wheels by the hand) or via various automated systems such as electric motors. Wheelchairs are used by people for whom walking is difficult or impossible due to illness (physiological or physical), injury, or disability.
A wheelchair assists people to become more mobile and independent. There are many different types of Wheelchairs that are used for various reasons. It is important to understand the limitations and safe operation of whatever wheelchair you choose.
The chair seat size (width and depth), seat-to-floor height, footrests/leg rests, front caster outriggers, adjustable backrests, controls, and many other features can be customized on, or added to, many basic models.

This walker, which has wheels on the two front legs, is helpful if you need some, but not constant, weight-bearing help.
