New University of Otago–Ōtākou Whakaihu Waka research shows that head injury data collected from smart mouthguards is run through a model that does not account for people of different sexes, ages and sizes. Taking a one-size-fits-all approach to analyzing data from smart mouthguards may mean serious injuries are missed, the study shows. The findings are published in the Journal of Biomechanics.
