A wheelchair is moved either manually (by pushing the wheels with the hands, or pushed from behind with handles by somebody who is not sitting in the wheelchair) or by automated systems such as electric motors which can be controlled by the wheelchair user (the person sitting in the chair) or by somebody walking behind or beside the wheelchair if the wheelchair user needs help to move their wheelchair.
Wheelchairs are used by people for whom walking is difficult or impossible due to illness, injury, or disability. Wheelchairs can have extra cushions and other parts added to improve support if the wheelchair user cannot keep their body in a good sitting position, or to make the wheelchair more comfortable to sit in. The earliest record of the wheelchair in England dates from the 1670s [Oxford English Dictionary, (2nd Ed.), 1989, Vol. XX., p. 203.], and in continental Europe this technology dates back to the German Renaissance.
