Virtual rehabilitation has been the focus of considerable research for many years, but the recent upsurge in consumer-ready virtual reality hardware and software has led to an increased interest in its use for a variety of clinical and home settings. In order to balance the upsurge in demand for innovative technological healthcare tools, there is need for a credible evidence base for its use and guidance for practitioners on which systems and applications are suitable for different patient populations and rehabilitation goals. This promising branch of healthcare is already being used to benefit many patients in homes and clinics around the world, but it is evident that there is still much more to learn if researchers are to continue to push the boundaries of clinical innovation and excellence. In this book, the authors present recent research addressing a number of these important topics, adding to their understanding of the complex issues and clinical considerations in virtual rehabilitation research and application.
