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 |
