Corrected: An earlier version of this story misstated the number of states with pending concussion laws. The actual count of states with pending legislation is 11. The District of Columbia also passed a law on July 27.
Includes updates and/or revisions.
With mounting on the dangers of student-athlete concussions, a majority of states have ramped up their legislative efforts to get concussion-management laws on the books.
By the time high school football practice kicked off toward summer鈥檚 end, 31 states and the District of Columbia had passed a student-athlete concussion law. Eleven more have similar legislation pending. In late February, only 11 states had such laws.
鈥淚t is only a matter of time until there are data showing how these state concussion laws are preventing catastrophic injuries, saving lives, and preventing chronic outcomes from repeated concussion,鈥� said Dr. Kevin Guskiewicz, the director of the at the University of North Carolina at Chapel Hill.
A concussion occurs when the head jostles back and forth rapidly, causing the brain to shift in the skull. Unlike broken bones, concussions leave no visible marks, which may cause some student-athletes to downplay the severity of their injuries.
In every concussion law passed so far, except for those of Idaho, Vermont, and Wyoming, some version of this idea appears: If a student-athlete is suspected of sustaining a concussion, he or she must immediately be removed from competition and obtain medical clearance before returning to play. That, in theory, would help counteract student-athletes鈥� trying to hide their symptoms to continue playing.
States like New Mexico, New York, and Oregon go further, requiring student-athletes to remain symptom-free. Some experts argue that the provision doesn鈥檛 pack much punch, though, as doctors are unlikely to clear an athlete who still exhibits signs of a concussion.
鈥淗aving persisting somatic, cognitive, and/or emotional symptoms is one sign of acute concussion,鈥� said Christine Baugh, the research coordinator at the Boston University Center for the Study of Traumatic Encephalopathy. 鈥淲hat this means is that the symptoms are a sign that the athlete鈥檚 brain is still healing. Therefore, no doctor should clear a student-athlete to return to play if any symptoms are apparent.鈥�
Symptoms include memory impairment, inability to concentrate, irregular sleep patterns, headaches, nausea, dizziness, and sensitivity to light or noise.
About half the states with laws require coaches鈥攖he ones responsible for recognizing the symptoms and removing players from practice or games鈥攖o undergo regular concussion-recognition training. A few extend the requirement to school nurses, athletic trainers, volunteers, and officials involved in interscholastic athletics.
All but six states鈥擟olorado, Connecticut, Idaho, Nebraska, Oregon, and Wyoming鈥攚ith concussion laws also require schools to issue concussion-awareness information to parents to sign and return before their children can play.
With the momentum for student-athlete concussion laws continuing to build nationwide, some experts believe there鈥檚 plenty of room for laws to develop further.
鈥淎ll states鈥� laws have not been able to cover the spectrum, and I hope this is ultimately where we end up,鈥� Dr. Guskiewicz said.
鈥楳odel Legislation鈥�
An estimated 146,000 high school student-athletes sustained concussions in the school year, according to from the Center for Injury Research and Policy, in Columbus, Ohio. That number jumped to about 187,000 in the 2009-10 school year, which can be partially attributed to higher concussion awareness and thus better reporting.
A recent in the online journal Brain Pathology revealed that one traumatic brain injury, such as a concussion, suffered even in childhood, can cause permanent damage to the brain. Another , recently published in the journal Pediatrics, found that a number of student-athletes鈥� deaths caused by head injuries would have been preventable with better equipment and more defined return-to-play guidelines.
The National Football League, which has encouraged all 50 states to adopt student-athlete concussion laws, calls Washington state鈥檚 2009 鈥渕odel legislation.鈥� It was named after Zack Lystedt, a former high school football player who nearly died on the field after he suffered a concussion and continued playing.
Specifically, the NFL points to three characteristics of that law that should appear in all states鈥� versions: requiring parents or guardians to sign a concussion-information form; removing student-athletes suspected of concussions from play; and making concussed student-athletes obtain medical clearance before returning.
Of the 31 states that already have laws, along with the District of Columbia, 25 meet the criteria, as does D.C. Of the 11 with pending legislation, only Michigan鈥檚 and New Hampshire鈥檚 bills don鈥檛 satisfy all three criteria.
While Colorado鈥檚 law doesn鈥檛 meet the NFL standard, it does include a feature that only a handful of states share: The rules extend past school sports, into private youth-sports organizations such as Little League and Pop Warner. Most of those states require private organizations to follow similar rules, if not carbon copies, of what all schools must do.
What鈥檚 Next?
Experts on concussions have come up with a number of recommendations to minimize the risks to student-athletes. The most notable include:
鈥� Baseline concussion tests. Administered before the start of a sports season, these tests are meant to measure the normal levels of brain activity in a healthy student-athlete. When a concussion is suspected, the athlete retakes the test, and a medical professional compares the results. The larger the difference in the responses, the higher the likelihood of a concussion. Research suggests baseline concussion tests are critical for accurate diagnosis, yet no state currently requires schools to use them.
鈥淎thletes vary tremendously on these tests,鈥� said Dr. Mark Lovell, the chief executive officer of ImPACT, a Pittsburgh-based company that issues baseline tests, 鈥渁nd if you don鈥檛 have a baseline, it is difficult to detect change in the case of mild or subtle injury.鈥�
鈥� Return-to-play guidelines. A growing number of neuroscientists believe that once a student-athlete obtains medical clearance to return after a concussion, he or she should do so gradually. The 2008 recommended a five-step process, in which athletes would have to remain symptom-free for 24 hours to advance through a protocol of light aerobic exercise, sport-specific activity, noncontact training drills, full-contact practice, and finally, return to play. No state currently mandates a specific return-to-play model.
Ms. Baugh of BU supports the same model as outlined in the Zurich consensus statement. 鈥淚f symptoms reappear at any time during this gradual reintroduction, the stepwise return-to-play system will allow for intervention and reduction of activity,鈥� she said.
鈥� Mandatory training for adults. Ideally, experts say, coaches, school nurses, athletic trainers, and other adults involved in youth sports should undergo concussion training annually. Training should include information about concussion symptoms, recognition hints, and the dangers of returning to play before being fully healed.
Dr. Guskiewicz of UNC鈥檚 Gfeller center says that future concussion laws need a clearer description for 鈥渢raining in concussion management for clinicians.鈥�
鈥淲hile difficult to police or regulate, it would eliminate the confusion and would improve care.鈥�
鈥� Extending coverage. Roughly a half-dozen states already extend their concussion laws beyond school sports, including to private youth organizations. Those states largely make the private sports leagues follow the same rules.
鈥� Limiting contact. Ms. Baugh said that current laws fail to 鈥渓imit the overall number of impacts incurred by these student-athletes, at least in any meaningful way.鈥�
鈥淏ecause these athletes take more than half the hits in practice, limiting the number of 鈥榟itting practices鈥� is the easiest answer,鈥� she said.
Idling in Congress
Rhode Island has legislation pending that would define the exact kind of medical professionals who can clear student-athletes, require coaches to undergo training, suggest training for nurses, and make baseline testing mandatory.
And earlier this year, federal lawmakers reintroduced a bill in Congress that would require school districts to educate parents, coaches, and student-athletes about the risk of concussions, along with a 鈥渨hen in doubt, sit out鈥� policy for those with symptoms. The bill has idled in a House subcommittee since late February.
