Methodology and Considerations for Combining Historic Accelerative Loading Research to Update the U.S. Army Aeromedical Research Laboratory Head-Supported Mass Injury Curve Using Survival Analysis
Abstract
Military helmets are multi-functional tools that provide blunt and ballistic impact protection and are frequently used as a mounting platform for life support and operational enhancement technologies. The frequent use of these helmet-mounted technologies can increase the risk of cervical spine injury, both acute and chronic, to Warfighters due to the increase in head-supported mass (HSM) and changes in the location of the combined center of mass (CM) of the helmet and helmet-mounted technologies. Evidence of an increased neck injury risk was provided through epidemiological research. This evidence led the U.S. Army Aeromedical Research Laboratory (USAARL) to investigate and develop HSM requirements for Army rotary-wing helmets in 1997 (McEntire and Shannahan, 1997). Over the 25 years since the introduction of the USAARL HSM Curves, additional research has been conducted into the effects of HSM and HSM CM location.
