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.


To enhance the quality and uptake of concussion research, and to improve clinical care for concussion.
