Wheelchairs

Extracted from the Wikipedia article Wheelchair.
Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, and individualized controls, and may be specific to particular activities, as with sports wheelchairs and beach wheelchairs. The most widely recognized distinction is between motorized wheelchairs, where propulsion is provided by batteries and electric motors, and manual wheelchairs, where the propulsive force is provided either by the wheelchair user or occupant pushing the wheelchair by hand (self-propelled), by someone else pushing from the rear using the handles, or pushing from the side using a handle attachment.
