Low back pain (LBP) affects 50-80% of adults at some point in their lifetime, yet the etiology of injury is not well understood. Those exposed to repeated flexion-compression are at a higher risk for LBP, such as helicopter pilots and motor vehicle operators. Animal injury models offer insight into in vivo injury mechanisms, but interspecies scaling is needed to relate animal results to human.

Many sensors are worn on the skin or in headgear and can suffer from motion artifacts introduced by the compliance of soft tissue or decoupling of headgear from the skull. The instrumented mouthguard is designed to couple directly to the upper dentition, which is made of hard enamel and anchored in a bony socket by stiff ligaments.

- Researchers conducted biomechanical tensile testing on cadaver cervical spines from ages 20 weeks gestation to 18 years to understand how the spine's failure properties change as a person grows.
- The study found that as children age, their cervical spine becomes stiffer and requires more force to fail, while the amount of movement before failure decreases.
- This research highlights the unique vulnerability of young spines, particularly in the upper cervical region, suggesting a correlation with higher rates of spinal cord injuries in kids without visible damage on X-rays.
