Abstract

The human tolerance literature pertaining to direct head impact is reviewed and discussed. The basis for the Vienna Index, the Effective Displacement Index, the Severity Index, the Head Injury Criteria of USMVSS 5208, the Wayne State Head Injury Tolerance Curve and the Maximum Strain Criteria will be examined and the correlation of these various indices with the available data demonstrated. Additionally, the prediction of injury for various impact pulses when used with the variety of available criteria will be determined.

Where appropriate, new data will be introduced to complete the existing data set. It is felt that on the basis of the currently available information regarding the limits of head impact tolerance that tolerance can be established for impacts of arbitrary direction.
