Abstract
This study proposes new injury predictors for concussive brain injuries, which do not contain any skull fractures. The new predictors describe characteristic features of rotational head motions due to impact, which can be calculated from 3-2-2-2 array head acceleration data on Hybrid-III dummies. CSDM (Cumulative Strain Damage Measure), which could predict concussive brain injuries, was obtained from a well validated human brain finite element model using concussive and non-concussive head acceleration data obtained from football games. The new predictors were also calculated using the data. This study found significant correlations between new injury predictors and the CSDM.
