Biomechanical performances of old-fashioned leather and modern football helmets
Date:5/7/2013

spect to head impact doses and head injury risks at the severity level of subconcussive injury. Rowson and coauthors state that they offer "biomechanical analysis based on helmet testing methodologies that compare relative helmet performance." The source of their disagreement with the Bartsch study centers on the different methods used by the authors of the two studies. Much of the discussion explains how differences in impact testing methodologies can influence the resulting data.

In an editorial companying the paper by Rowson and colleagues ("Editorial. Leather football helmets," by Adam Bartsch, Ph.D., Edward Benzel, M.D., Vincent Miele, M.D., and Vikas Prakash, Ph.D., also published today online, ahead of print in the Journal of Neurosurgery), Dr. Bartsch and colleagues defend the study they published in the Journal of Neurosurgery in 2012 and state that differences in results between the two studies are based on the different testing methodologies used by the two groups of researchers and the resulting head motions that were induced. They state that their study simulated both linear and rotational head motion, whereas the drop test used by Rowson and colleagues provided mainly linear head motion. Bartsch and colleagues reiterate that their data demonstrated test conditions akin to common on-field impact scenarios, which cause both linear and rotational head motion. These researchers call for continued examination of experimental protocols that may lead to better quantification of helmet performance during simulated on-field conditions.

In their response to the editorial, Rowson and colleagues discuss points of difference and agreement between the two sets of researchers and their methodologies.
