Abstract: Mild traumatic brain injury (mTBI) is linked to neurodegenerative disease found in military veterans and athletes. mTBI is thought to be caused by head acceleration during impact, but specific tolerable acceleration levels remain unclear. Animal studies suggest that acceleration tolerance varies substantially in different anatomical directions. However, directional sensitivity in humans is unknown due to subjective neurological outcomes and lack of head acceleration measurements during injury in all linear and rotational directions (ie six-degrees-of-freedom or 6-DOF). Our objective was to measure injury and non-injury human head impacts in 6-DOF to determine if the human brain’s tolerance to injury is direction-dependent.
