Athletes at the Paralympics in 1972 were all afflicted by spinal cord injuries and required the use of a wheelchair.[2] This is in contrast to later Paralympics that include events for participants that fit into any of five different disability categories; amputation, either congenital or sustained through injury or illness; cerebral palsy; wheelchair athletes; visual impairment, including blindness; Les autres, any physical disability that does not fall strictly under one of the other categories, for example dwarfism or multiple sclerosis.[3][4] Each Paralympic sport then has its own classifications, dependent upon the specific physical demands of competition. Events are given a code, made of numbers and letters, describing the type of event and classification of the athletes competing.[5][6]
