The Virginia Tech Helmet Lab specializes in the field of injury biomechanics with particular emphasis on investigating head tolerance to impact loading. This research involves the identification and characterization of injury mechanisms, quantification of the biomechanical response to impact, determination of tolerance levels, and evaluation of protective design. Applications of this research include sports, automobiles, and military injury prevention. In an effort to educate the public on the effectiveness of protective headgear in sports, the Helmet Lab has developed a 5-Star Ratings system. These ratings have been applied to several sports headgear and helmets to evaluate their ability to reduce concussion risk. More information can be found at www.vt.edu/helmet.
