In the medical model, disabled people are seen as the problem. They need to change and adapt to circumstances (if they can), and there is no suggestion that society needs to change. This model reflects the World Health Organization definition of disability.
The social model has been developed by disabled people. In their view disability is caused by the barriers that exist within society and the way society is organised, which discriminates against people with impairments and excludes them from involvement and participation. This model reflects the Union of Physically Impaired Against Segregation (UPIAS) definition of disability.From
