The goal of this book is to bring together ideas from several different disciplines in order to examine the focus and aims that drive rehabilitation intervention and technology development. Specifically, the chapters in this book address the questions of what research is currently taking place to further develop rehabilitation, applied technology and how we have been able to modify and measure responses in both healthy and clinical populations using these technologies. The following chapters are dedicated toward addressing these issues: 1) Does Training with Technology Add to Functional Gains?; 2) Are there Rules that Govern Recovery of Function?; 3) Using the Body’s Own Signals to Augment Therapeutic Gains; 4) Technology Incorporates Cognition and Action; 5) Technology Enhances the Impact of Rehabilitation Programs; 6) Summary.
