Quantification of subconcussive impact forces to the head using a forensic model

Abstract

Concussive and subconcussive head injury is a global phenomenon that affects millions of people each year. Concussive injury has been extensively studied in sport, which has led to a greater understanding of the biomechanical forces involved and guidelines aimed at preventing athletes from playing while concussed. Subconcussive forces by definition do not meet the threshold for concussion but nonetheless may have significant long term consequences due to the repetitive pattern of injury to the head. Quantifying these impact forces using a forensic head model provides the groundwork for future studies by establishing a range or threshold of subconcussive impact forces that could be correlated with clinical assessments. The use of a forensic head model has distinct advantages in terms of ethics and safety.
