Figure 3. Aggregate distributions of kinematic criteria.

Figure 3

Field data for six kinematic criteria is plotted against the range of values produced by the highest drop heights in the NOCSAE standard protocol on the twin-wire drop test (yellow region) and exposure-weighted distribution of drop test data (black bars). We also compared the range covered by NOCSAE to 116 mTBI impacts recorded in previous studies: n = 2 using our instrumented mouthguards (red circles) (Hernandez et al., 2014), n = 89 using the Head Impact Telemetry System (HITS) (green circles) (Broglio et al., 2011; Duma and Rowson, 2009; Guskiewicz et al., 2007; Rowson et al., 2012), and n = 25 using NFL reconstructions (purple circles) (Newman et al., 2000a,b; Pellman et al., 2003).
