Bushnik T. Traumatic Brain Injury Model Systems of Care 2002−2007. During the years 2002 to 2007, 16 Traumatic Brain Injury Model Systems of Care (TBIMS) were funded by the National Institute on Disability and Rehabilitation Research to conduct site-specific and collaborative research projects, including contribution to a longitudinal database, within comprehensive systems of care specialized for people with traumatic brain injury. The TBIMS program has been in existence since 1987 and has undergone significant modifications over these years. Herein I provide an overview of the changes that occurred in the 2002−2007 funding cycle, the research initiatives that were carried out during that time, and brief descriptions of the 13 original TBIMS research articles included in this issue of Archives.
