There has been a great deal of development in the game of football in order to make the game as accessible as possible to those who want to play it, whatever their disabilities. There have been various changes in the rules to assist those with impairments to be able to play, but the idea is that the game should be kept as close as possible to the standard port for non-disabled players. Variations of football have been formulated to  allow virtually any diabled person to take part. There are football teams for blind people, powered wheelchairs, football for those with cerebral palsy, with learning difficulties and for amputees and the deaf – all will have separate organisations, though people with different disabilities may play in the same team – or they may play in teams that have been assessed to have people at similar levels of ability playing together. (This is not just about impairments but about knowledge and experience of the game itself). For example, those with affected vision will be classified as “blind” and “partially sighted”. Players with a learning disability are eligible if they have an assessed IQ of within or below 70-75. In game rules for those with cerebral palsy there are 7 a side players and 30 minutes a half, and a pitch of 60 years by 40 years but full-sized goals. Players are allowed to either throw or roll a ball in if it goes out of play (this to allow fairness for those with hemiplegia)
