This website contains information for physicians and patients alike. Much of the material is taken from the textbook, Croft AC: Whiplash & Mild Traumatic Brain Injuries, SRISD Press, San Diego, CA, 2009. Other information is available from Whiplash in Hypertext 4.0, a software program available from the Spine Research Institute of San Diego. This website, however, provides only a fraction of the material contained in the more than 500 pages of the book. The landscape of the field of study of whiplash and brain injury traumatology changes more dramatically than most medical literature from year to year—a situation that prompts the Annual SRISD Scientific Conferences.
