Computer microtechnology for a severely disabled preschool child.

The developments and considerations essential to providing microtechnological aids for a preschool severely disabled child confined to a bed in a hospital ward are described. This single case report illustrates the needs of a quadriplegic boy dependent on a ventilator via a tracheostomy. Provision of a computer, a variety of specially designed switches and software together with a self-driven powered wheelchair maximized expression of his developmental needs. The decision-making process of providing the equipment is described as well as the problems encountered. His development in language and cognitive skills is discussed in the context of his change in experience and competence as he learned to control the technological aids.
