The most important findings of these combined studies have been 1) that concussions can occur at lower impact magnitudes than previously thought; 2) that measures of linear acceleration appear equally important to cause concussion as angular acceleration; 3) that athletes can sustain a high number of head impacts in a season (many exceeding 80g-90g) and never sustain a diagnosed concussion; and 4) clinicians should not attempt to use impact magnitude or location to predict acute clinical outcomes of symptom severity, neuropsychological function, and balance. Our earlier studies, combined with those of several other studies on this topic, call for more research to be conducted to investigate how linear and rotational accelerations relate to measures of symptom severity, neurocognitive function, and postural stability in larger sample sizes across the entire recovery period. In addition, the role of this technology should be further investigated to identify its use for behavior modification and improved player mechanics.
