The public health impact of brain injury from repetitive sub-concussive head blows during team sport is potentially dramatic, and DTI has been used to study brain injury associated with concussions. In this study, we conducted three longitudinal DTI studies of a group of 10 college football players before and after a regular football season, along with mechanical force data recorded by helmet-embedded sensors throughout the season. Despite a small sample size, the study finds that longitudinal changes in DTI measures and mechanical force show strong significant correlations when comparing pre- and post-season data.
