Mild TBI Task Force


SEEKING FEEDBACK on draft Definition of Mild Traumatic Brain Injury

The Mild TBI Task Force of the ACRM Brain Injury Interdisciplinary Special Interest Group (BI-ISIG) published a Definition of Mild Traumatic Brain Injury (TBI) in 1993. Over the last two years, the task force has been preparing an update of this definition.

After Delphi consensus voting and revisions, we are now seeking input on this draft Definition of Mild TBI from organizations and the public through a brief survey.

To participate, please click the “BEGIN SURVEY” button below to review the draft Definition of Mild TBI and submit comments BY 17 JANUARY.



To enhance the quality and uptake of concussion research, and to improve clinical care for concussion. If you are interested in joining this task force, please contact the chair, Noah Silverberg.
