Commotio Cordis: Proposed NOCSAE Standard for Chest Protectors

“If we can stop a bullet, we can stop a ball”

Baseball is arguably one of the safest team sports. But it’s also where we see the most incidents of commotio cordis, a sudden cardiac arrhythmia caused by a direct blow to the chest. While instances of commotio cordis are rare, one death is too many.

Heart attacks among teen athletes are quite rare, and are most often a result of an underlying physical defect. Commotio cordis has no correlation to the physical health of the victim. According to lab tests at Tufts University Medical Center, it occurs when an object traveling approximately 40 mph makes impact directly over the heart in the milliseconds between heartbeats.

Who’s at risk and why

Catchers, pitchers and infielders are most at risk for blows by high-speed balls. Lacrosse and hockey players are also susceptible to being struck by rocketed balls and pucks. Boys under the age of 15 are most at risk of commotio cordis because their chest walls are still flexible as their bones continue developing into their early 20s.

The best chance victims have for surviving commotio cordis is resuscitation by a defibrillator, a device not housed at every ballfield. And if one is available, there needs to be someone in attendance who has been trained in its proper use.

Equipment manufacturers relying on science to help reduce the risk

But researchers are coming up with another solution. Statistics show that nearly one third of commotio cordis victims collapsed while wearing chest protection of some sort, which means that the protection athletes were given wasn’t good enough.

In January, the National Operating Committee on Standards for Athletic Equipment (NOCSAE) proposed the first standard for chest protectors used in baseball and lacrosse with the intention of reducing the risk of cardiac events. To meet the standard, manufacturers have to come up with a material that will distribute the force of the blow but not affect movements of the players.

Earlier this year, Mark Link, a Tufts University Medical Center heart specialist, published results of tests run on a model made of foam and a combination of polymers that appears promising. The company that developed the material, Unequal Technologies, plans to test it’s chest protectors and heart-covering shirts against the NOCSAE standard. Other manufacturers are visiting the NOCSAE laboratories to educate themselves on the testing process so they can modify their products to comply with the standard.

Youth Athletes and Concussion Recovery

Too many parents following outdated medical advice

Starve a cold, feed a fever. Swimming within 30 minutes of eating causes cramps. Cracking your knuckles causes arthritis. Tilt the head back to stop a nosebleed. All outdated but once heavily relied upon advice from the medical community. Sadly, these and similarly unsubstantiated notions continue to circulate. And apparently so are incorrect ideas about concussion recovery.

Despite ongoing media attention and education efforts surrounding concussions, research shows that many parents still rely on outdated advice when monitoring their concussed children. Where once the impact of concussions was downplayed, apparently now parents are going to the opposite extreme and impeding recovery.

A national survey conducted by UCLA Health asked 569 parents how they would care for a child with concussion symptoms that persisted a week following the head injury. More than 75% said they would wake their child to check on them throughout the night and 84% said they would not permit the child to participate in any physical activity. About 65% said they prohibit use of electronic devices.

Making a healthy recovery

Frequent disruption or lack of sleep can affect memory, moods and energy levels, which are exactly what doctors use to measure concussion recovery. Once the child has been examined by a medical professional and determined to be at no further risk, sleep will help the brain recover more quickly, according to Christopher Giza, a UCLA paediatric neurologist.

And while contact sports are to be avoided until the child is fully recovered and cleared by a medical professional, mild exercise and aerobic activities such as walking and bike riding promote the healing process and overall good health.

As for electronic devices, it’s a good idea to keep kids off them during the early days of the injury. But easing them into their normal social, intellectual and physical activity is what’s best.

Most concussion patients make a full recovery, though dizziness and headaches can persist for weeks. Parents should always heed the advice of the physician monitoring the child and remember that rest and pain relievers for headaches are the best treatments in most cases.

Protecting Against Risk of Commotio Cordis

Study shows new chest protector is effective and youth athletes most at risk.

Athletic chest protectors are critical to the safety of hockey and lacrosse goalies, baseball/softball catchers, and umpires. There is a wide assortment of chest protectors on the market, most of which have proven to be less than adequate against serious injury and can give a false sense of security.

But one manufacturer’s product apparently now offers better protection from potentially fatal blows to the chest.

The Unequal Technologies HART Chest Protector have proven 95 percent effective in the prevention of Commotio cordis,  according to a study published in The Clinical Journal of Sports Medicine. Commotio cordis is a sudden disruption of the cardiac rhythm caused by a forceful impact to the chest that often results in fatal cardiac arrest.

Unequal Technologies develops protective padding for a variety of athletic of headgear, including the popular Halo headband.

Youth athletes under the age of 16 are most at risk from such incidents. About 10 to 20 cases occur annually in the U.S. More than one-third of Commotio cordis incidents occur in athletes wearing chest protectors, according to a study published in 2013. Therefore, it’s paramount that appropriate padding is properly placed.

Youth Baseball and Eye Injuries

Looking at preventative measures

As everyone knows, baseball season is now in full swing. But what many probably don’t know is that youth athletes under the age of 14 incur more eye injuries in baseball and softball than any other sport. In rare instances, these injuries can result in permanent damage or even blindness.

Overall, there are more than 40,000 eye injuries reported each year, most occurring in baseball and basketball, followed by water and racquet sports. Balls, bats, pucks, racquets, and sticks are used in the sports that pose the highest risk for eye injuries. These sports also typically include body contact.

The leading cause of child blindness in the U.S. is injury, with most cases occurring in sports-related activities, according to the National Eye Institute. Penetration, blunt trauma and radiation are the most common causes of sports-related eye injuries. Exposure to the sun’s ultraviolet rays can result in radiation damage, which can be a particular risk when snow skiing, water skiing and participating in other water and snow sports.

Prevention measures

According to Jay Novetsky, 90% of sports-related eye injuries are preventable. Novetsky, an eye surgeon at the Vision Institute of Michigan, advocates for protective eyewear as part of every sports’ regulated safety equipment, such as safety shields, safety glasses, goggles and eye guards.

To specifically prevent injuries in baseball, batting helmets can be fitted with protective face guards and fielders can wear safety-certified sports goggles.

Many people don’t realize  that prescription glasses (and sunglasses) worn during play not only don’t offer protection, but they increase the risk of eye injury. Street eyeglasses and contacts can easily shatter upon impact and puncture the eye and surrounding areas.  Athletes who wear glasses or contacts can usually have their prescriptions matched in protective eyewear.

Return to Play

In order to return to play following an eye injury, the eye should be pain free, cause no discomfort and vision returned to normal. Release by an ophthalmologist should be required before an player with a serious eye injury returns to play. The team physician or athletic trainer should be able to determine if and when players with less serious eye injuries can return. Athletes returning to play following an eye injury should be required to wear eye protection to avoid a second injury.
