When it comes to effectiveness in protecting soldiers from certain types of traumatic brain injuries, your great-grandfather’s World War I helmet might be just as effective, if not more effective, a new study by Duke University researchers has found. According to a news report on PBS, the study looks at the effects of overhead explosions. But it still raises questions about why today’s military helmet designs, with all the technological advances we have today, are not significantly better when it comes to head injury protection compared to helmets used more than 100 years ago.
What the Experiment Found
The team of Duke University’s biomedical engineers conducted their experiment by placing various styles of World War I helmets and modern helmets under a “shock tube,” which simulates an artillery shell exploding between 3 and 15 feet away. The researchers then compared the impact on the helmets to the likelihood of brain injury from that level of pressure. The results showed that the older helmets were just as likely to prevent brain damage as any designs being used today.
A soldier wearing any of the helmets is five to 10 times less likely to experience bleeding in the brain from an overhead blast than someone without a helmet, the study showed. In fact, the 1915 French “Adrian” helmet provided the most protection, researchers found – even more than that of modern helmets. The study’s authors say they were surprised by the results because modern helmets have multiple layers of materials to prevent injuries.
The older helmets used during World War I were mostly just formed out of a thin layer of steel. At the time, people knew very little about traumatic brain injuries. So, the helmets were designed to shield soldiers’ heads from shrapnel, not shockwaves. The protection that is provided against brain injuries, researchers concluded, was a fortunate byproduct. However, researchers say they would not suggest that present-day soldiers use these old helmets. Today’s helmets, they say, are much better at preventing shrapnel injuries and against shockwaves from roadside bombs or improvised explosive devices.
More Awareness About Brain Injuries
The awareness of traumatic brain injuries has grown by a lot in recent years. Brain injuries have been linked to mood and anxiety disorders as well as a higher risk of suicide. Studies estimate that between 11% and 23% of U.S. military personnel who return from Iraq and Afghanistan likely have a TBI. Today, we know the long-term effects of traumatic brain injuries. We know that even concussions cause long-term brain damage.
Traumatic brain injuries, regardless of how they occur, can result in the need for significant medical and rehabilitation expenses.
