Table 4.

Average concussive linear acceleration and rotational kinematics for impacts that were either primarily sagittal plane rotation (front and rear impact locations), primarily coronal plane rotation (side impact locations), or to the top of the helmet

Number of concussions Linear acceleration (g) Rotational acceleration (rad/s2) Rotational velocity (rad/s)
Sagittal plane rotation 33 102.7 ± 33.6 4986 ± 1909 22.1 ± 8.5
Coronal plane rotation 7 105.8 ± 16.6 5192 ± 1166 23.0 ± 5.2
Impacts to helmet top 17 100.6 ± 37.1 2192 ± 1790 9.7 ± 7.9
