Virtual reality (VR) is the computer technology underlying the latest generation of interactive computer games, but its uses go far beyond this. One very exciting area of potential application of VR is neurological rehabilitation. This article outlines four ways in which VR might be used: assessing neurological deficits, increasing patients' levels of interaction with their environments, specific retraining of impaired skills, and, in conjunction with other technologies, as a prosthetic mechanism.

The view that brain damage in children is less impairing than equivalent damage in adults is no longer acceptable. However, it is acknowledged that recovery following brain damage, when it does occur, owes much to the plasticity of the brain and that the young brain displays greater plasticity than the mature brain. To maximize brain damage recovery in children we need to focus both on what is known about brain plasticity and how to influence it. Research on environmental enrichment in rats has told us that enforced interaction with a complex environment can both stimulate anatomical and biochemical plasticity and ameliorate some of the behavioural consequences of brain damage. The view that environmental interaction has rehabilitative value also accords with clinical experience. However, the sensory, motor and cognitive consequences of brain damage often conspire to make environmental interaction difficult. One potential solution lies in using computers to generate virtual environments tailored to the precise sensory and motor capacities of the brain-injured child. In this way children may be enabled to benefit from environmental interaction whatever their level of disability. The use of Virtual Reality (VR) in the context of rehabilitation is discussed and relevant work reviewed.
