Loss of consciousness is a poorly understood indicator of concussion severity. Conflicting results have been published supporting loss of consciousness as a severe concussion as well as having no relationship with severity. Understanding how loss of consciousness relates to brain trauma severity will provide useful insights to guide rule changes and return to sport protocols. The purpose of this study was to compare magnitudes of head acceleration and brain tissue deformation for punches resulting in a loss of consciousness and punches that do not.
