Inadequacies in computer access using assistive technology devices in profoundly disabled individuals: An overview of the current literature

The study depicts the evolution from a 'medical model' to a 'social model' in rendering AT services for these individuals. Prescribing the proper device to enable computer access to persons with severe disabilities is a complex undertaking, and services have been inadequate. Technological advances that enable computer access for persons with disabilities have not reached those persons that need it most, particularly those with severe disabilities, for a number of reasons. The literature is replete with explanations for the underutilization of AT for computer access including prejudicial views towards persons with disabilities, inadequate assessments, lack of a person-centered approach, and methods for practice that are not evidence based.
