"Seventy-five percent of Griffon Helicopter aircrew have reported various levels of neck pain as a result of performing flying tasks, and 23% have been grounded due to neck trouble. In the past, Defence Research and Development Canada (DRDC) has been involved in neck trouble research focussing on Finite Element modelling techniques in order to understand neck pain mechanisms. Some have argued that this line of research has not led to tangible solutions in Canada; however, others have used modelling as a necessary tool in the development of neck pain mitigating solutions. This paper argues that conceptual, physics based, and empirical models can be used at various stages to help define the scope of the problem, suitable verification and validation tests and provide a path for the solution’s development, design, and assessment. This has led to a description of the NATO HFM 252 framework as well as mathematical equations that estimate neck loading due to helmet system mass properties. It is concluded that these modelling activities are essential for ethical and cost effective neck trouble research"--Abstract, p. i.
