It was formulated by fitting the Wayne State Tolerance Curve, which is based on skull fracture data. It incorporates impact duration into the assessment of head and brain injury risk. Linear acceleration using "g" as unit, time "ms" as unit. See Ref for equation. The integral is evaluated over the period of time from when the linear acceleration first exceeds 4g to when it returns to 4g after the largest peak. |

Total number of exposures registered - A single exposure refers to one occurrence of head impact/inertial exposure. The number of exposures registered refers to the total number of such occurrences over the duration of data collection. For example, if data collection occurred over a single American Football game for one player, and the player's head accelerometry device registered 30 impacts, the number of exposures registered would be 30. It is important to consider that for some sensor systems that they don't differentiate between actual play and things like halftime or water breaks. It can be challenging to measure true head impacts, not jumping up or down for example, unless that is the question being asked. |
