Return to Play Guidelines from Concussion

There is a lot of misinformation on concussion out there and I just read a very accurate article on return to play (RTP) guidelines from concussion.  This is a serious topic, and if you have any athletes in your household, you should take 15 minutes to read this blog.  I'd like to say that all healthcare professionals are knowledgable in this topic, but that isn't always the case. It is important that you find a healthcare professional that works with athletes on a regular basis and is familiar with these guidelines.  And always ask questions!!! If the healthcare professional can't answer those question, or you can't follow their line of logic, more times than not, they may not be the person you should be following advice from.  

 

Disclaimer:  If you suspect a concussion, please take them to a healthcare professional, this is blog is not mean't to replace a highly quaified professionals adivce.  Also, the following literature below was copied and pasted from www,Momsteam.com

 

Return to play (RTP) after a child or teen suffers a sport concussion is a step-by-step, graduated, exercise-limited process:

  1. Physical and mental (e.g. cognitive) rest while experiencing symptoms
  2. Exercise program of gradually increased intensity (but only after symptoms clear)
  3. Medical clearance
  4. Return to play. [1]

Physical rest

While bed rest is not required, strenuous activity  should be avoided until the athlete has no post-concussion symptoms at rest, with at least one study showing an association between athletes engaging in activities requiring high levels of physical exertion and greater impairment on computerized neurocognitive testing (e.g. ImPACT testing) and reports of more concussion symptoms. [8]Broad restrictions of physical activity are recommended, including: 

  • no sports
  • no weight training
  • no cardiovascular training
  • no PE classes
  • no sexual activity
  • no leisure activities such as bike riding, street hockey, and skateboarding that risk additional head injury or make symptoms worse. 

Cognitive rest

Just as athletes recovering from a concussion needs to get physical rest, they need to get cognitive (mental) rest as well.

Because a concussion impacts the brain's cognitive function (those that involve thinking, concentrating, learning and reasoning), not its structure, it makes sense that engaging in cognitive activities (in other words, doing something that requires thinking or paying attention ) is likely to make an athlete's concussion symptoms worse (although no conclusive link has been established to adverse long-term health effects)

As a result, both the most recent international consensus of concussion experts [1] and the American Academy of Pediatrics [2] recommend a period of near full cognitive rest in the first three to five days after injury, followed by a gradual return to cognitive activity, so long as it does not trigger a return of symptoms. 

Cognitive rest means:

  1. Time off from school or work;
  2. No homework;
  3. No reading;
  4. No visually stimulating activities, such as computers, video games, texting or use of cell phones, and limited or no television;
  5. No exercise, athletics, chores that result in perspiration/exertion;
  6. No trips, social visits in or out of the home; and
  7. Increased rest and sleep. [7]

      Such rest has been recommended despite the fact that, until June 2012, there was no empirical evidence to support such treatment. A small but growing body of empirical evidence now provides support for the recommendation. A 2012 study in the Journal of Pediatrics [7] documented the effectiveness of prescribed rest for the treatment of post-concussion symptoms and cognitive disfunction, whether the rest was applied in the early or prolonged stages of recovery.

      2014 study[12] by researchers from Boston Children's Hospital, Children's Hospital of Philadelphia and the University of Pittsburgh Medical Center found that teens who continued to engage in full cognitive activity after sport-related concussion took from two to five times longer to recover on average than those who limited such activity, with those who engaged in the most cognitive activity after concussion taking approximately 100 days on average to recover from their symptoms compared to approximately 20 to 50 days for patients who limited cognitive exertion.

      Significantly, the study found that those who engaged in less cognitive activity - ranging from complete cognitive rest to moderate cognitive rest all recovered at about the same pace.

      "While vigorous cognitive exertion appears detrimental to recovery, more moderate levels of cognitive exertion do not seem to prolong recovery substantially," said William P. Meehan, III, MD, Director of the Sports Concussion Clinic at Boston Children's Hospital and one of the study's authors, similar to those in a 2008 study [13which found that those who engaged in moderate levels of activity after concussion had better outcomes than those engaging in the highest and lowest levels of activity.

      "This seems to suggest that while limiting cognitive activity is associated with a shorter duration of symptoms, complete abstinence from cognitive activity may be unnecessary," said Dr. Meehan. 

      Researchers suggested that cognitive activity may have more of an effect on recovery in the period immediately after injury, and said additional research would be needed to determine how the effect of cognitive activity changes over time.

      "For the first three to five days, we tell our patients with concussions that they should really aim to be at a zero level or complete cognitive rest," said Meehan in an interview with the Boston Globe. That means no reading, homework, text messaging, or video game playing; basically, it's fine to lie in bed quietly, watching TV or listening to music with the volume on low. Those experiencing severe symptoms may prefer to be resting anyway," he said, "but those with mild symptoms may think they can go back to school or resume exercise right away, which may delay their recovery."

      After a few days, kids can slowly add mental activities such as doing a crossword puzzle or sending a few text messages to see how they feel. "If symptoms exacerbate, they should go back to resting," Meehan said. If they're feeling OK, they can continue to gradually add mental challenges, resuming some school work on a lighter schedule. Throughout, they should continue to assess their symptoms and cut back if the headaches or dizziness return.  

      Post-concussion classroom accommodations 

      Once physical symptoms clear, but before exercise is allowed, a gradual return to a full academic day can begin, with classroom accommodations.

      At the Lawrenceville School, a New Jersey prep school, for instance, a concussed athlete must stay in the infirmary on "strict rest in a darkened room with no iPod, no computer, and no reading" until his or her physical symptoms of concussion are at or close to their pre-injury baseline. At that point, he or she is gradually allowed to return to a full academic day, long-time Medical Director, Dr. Robin Karpf, tells MomsTeam.  "Their short-term memory and processing speed may continue to be off their baseline, but as long as they are not experiencing significant physical symptoms, I allow them back to the classroom with academic accommodations." (An e-mail is sent to all the athlete's teachers with information on the possible need for such accommodations).

      "We need to do more to educate teachers that adjustments may need to be made for a concussed athlete,"  Dr. Karpf said. Kids who don't get cognitive rest, she has found, are more likely to have concussion symptoms that linger longer.

      If the increased cognitive challenges of the classroom bring about a recurrence of their physical symptoms, Dr. Karpf says, she returns them to rest.  She does not start their gradual return to exercise or sports until they have returned to their neurocognitive baseline.

      The 2014 study by Meehan, et al,[12] also provides data to support the practice of putting academic accommodations[9,10] in place for student-athletes suffering sport-related concussions to allow for relative cognitive rest in a school setting, an important first step in the management of concussion. "Given our findings, it is likely that academic accomodations can speed the recovery process," the study says.

      Neal McGrath, PhD, Director of the Sports Concussion Center New England, who was not involved in the study, said it "provides important findings that help more firmly establish what clinicians who work with concussion patients see on a daily basis: sufficient cognitive rest is crucial, both in getting recovery on track in the early days post-injury and in facilitating recovery as students re-engage with academic challenges and information processing demands in their everyday lives."  

      Dr. McGrath, the author of a seminal 2010 article in the Journal of Athletic Training on supporting the student-athlete's return to the classroom after a sport related concussion,[14] said that, "the data provide the most sophisticated glimpse yet of a phenomenon that has been easy to describe clinically but hard to quantify. The study's average duration of symptoms - 43 days - reminds us as well that concussion recovery is a process that often takes considerable time in the life of a young person." 

      Conservative approach

      2010 study of high school athletes with concussions [3] reported that:

      • 27.0% had symptoms clear in less than 24 hours
      • 36.2% between 1 and 3 days,
      • 20.2% between 4 and 6 days,
      • 15.1% had symptoms lasting more than a week but less than a month; and
      • Only (1.5%) were still experiencing symptoms more than a month after injury. 

      Experts nevertheless caution that, while an estimated 80 to 90% of concussions heal spontaneously in the first 7 to 10 days, children and adolescents may require a longer rest period and/or extended period of non-contact exercise than adults because their developing brains cause them to experience a different physiological response to concussion than adults and take longer to recover, and they have other specific risk factors, such as the risk of second impact syndrome.

      A number of recent studies suggest that concussed adolescents, perhaps even more than younger and older athletes, take longer to recover full cognitive function and should be held out of play longer. One study found that concussed adolescents have difficulty recovering the ability for high level thinking after injury and may require extended recuperation before full recovery of so-called 'executive function' is achieved, with researchers at the University of Oregon and University of British Columbia finding that executive function was disrupted in concussed adolescents for up to 2 months after injury when compared to healthy control subjects.[11]

      In the absence of daily testing by a health care professional with concussion expertise (certified athletic trainer, school/team/primary care/sports medicine physician, neuropsychologist) to clear a student-athlete to begin the graduated return-to-play protocol, a student-athlete should observe a 7 day rest/recovery period before commencing the protocol. This means that, for such athletes, return to sports will take at least two weeks. Some leading concussion experts, including Dr. Rosemarie Scolaro Moser, a sports concussion neuropsychologist featured in the new PBS documentary, "The Smartest Team: Making High School Football Safer," recommend taking a minimum of three weeks off before returning to sports after a concussion.

      Younger students (K-8) should observe the 7 day rest/recovery period after they are symptom-free at rest prior to initiating the graduated-return-to play protocol.

      s young athletes tend to consider only a small subset of their potential symptoms when reporting their recovery or saying they are "back to normal" after concussion,[6] caution is urged in considering athletes' self-reported symptoms in their return-to-play decisions, and the same caution is warranted in relying solely on neurocognitive test scores having returned to normal before the graduated exercise protocol is begun.

      Indeed, a recent study [9] of concussed student-athletes who reported no symptoms and had returned to baseline on computerized neurocognitive tests taken before beginning the graduated exercise protocol, found that more than a quarter exhibited declines in verbal and visual memory on the tests after moderate exercise, prompting a recommendation that student-athletes not be cleared for full contact activity until they are able to demonstrate stability, particularly in memory functioning, on neurocognitive concussion testing performed after the exercise protocol is begun. While this was only one study, additional post-exercise neurocognitive testing may eventually become an important part of the RTP protocol.

      In practical terms, this more conservative approach means that:

      • Children and teens should not, under any circumstances, be allowed to return to practice or play until completely free of symptoms (note: a recent study; 
      • No return to play on the same day as the injury, regardless of competitive level (as is now the law in an all but a handful of U.S. states)and
      • "Modifying factors" (i.e. previous history of concussion, learning disabilities), take on more importance in the investigation and management of concussion. 

      Return to play guidelines

      Return to play after concussion should follow a six-step process:

      Stage
       Activity Objective

      1. No activity
      Symptom limited physical and cognitive (e.g. mental) rest (see above)
      Recovery

      2. Light aerobic exerciseWalking, swimming or stationary bicycle keeping intensity less than 70% of maximum predicted heart rate; no resistance trainingIncrease heart rate

      3. Sport-specific exerciseSkating drills in ice hockey, running drills in soccer.  No head impact activities
      Add movement

      4. Non-contact training drills
      Progression to more complex training drills, e.g. passing drills in football and ice hockey; may start progressive resistance trainingExercise, coordination and use of brain

      5. Full contact practice
      Following medical clearance, participate in normal training activities
      Restore confidence and allow coaching staff to assess functional skills

      6. Return to play
       Normal game play
       

       

      While many of the youth sports concussion safety laws passed by the states in recent years contain broad language allowing any "qualified health care professional" to make the return-to-play decision, studies show that many primary care physicians [10] lack the expertise required to make return to play decisions.  Because they have more training and experience in concussion diagnosis and management, certified athletic trainers, team doctors, and neuropsychologists are usually the best qualified to decide when it is safe for an athlete to return to play.

       

       

      7 + days to recover

      Generally, each step should take at least 24 hours, so that, assuming the athlete does not experience a reoccurrence of concussion symptoms at rest or with exercise as she progresses through the exercise program, she will be able to return to sports in about a week's time after symptoms have cleared.   

      If any post-concussion symptoms occur at any level, the athlete needs to drop back to the previous level at which she was symptom-free, and try to progress again after a further 24-hour period of rest has passed.

      The Model Policy and Guidance for Prevention and Treatment of Sports-Related Concussions and Head Injuries recently issued by the New Jersey Department of Education pursuant to that state's concussion safety law suggests that, in the absence of daily testing by a health care professional with concussion expertise (certified athletic trainer, school/team physician) to clear a student-athlete to begin the graduated return-to-play protocol:

      • A student-athlete should observe a 7 day rest/recovery period before commencing the protocol.
      • Younger students (K-8) should observe the 7 day rest/recovery period after they are symptom-free at rest prior to initiating the graduated-return-to play protocol. 

      While not as conservative as the model concussion management policy proposed by the New Jersey Department of Education, California recently became the first state to mandate a minimum 7-day waiting period after a concussion before a return to sports for interscholastic athletes, and to require the successful completion of a graduated return-to-play exercise protocol supervised by a health care professional which can only begin once a student-athlete is no longer experiencing concussion symptoms.

      Non-compliance is serious problem

      In their desire to return to the playing field, some high school athletes fail to comply with return to play guidelines.  A 2009 study [4] by researchers at Nationwide Children's Hospital in Columbus, Ohio found that at least 40.5% and 15.0% of athletes who sustained concussions returned to play prematurely under the now-outdated American Academy of Neurology (AAN) and then current Zurich return-to-play guidelines.  

      2011 study[5] however, shows for the first time the important role computerized neuropsychological testing is playing in concussion assessment and return to play decisions. Athletes who had taken a pre-season, baseline ImPACT computerized neuropsychological test, and took the ImPACT test again after suspected concussion were less likely to return to play on the same day, and less likely to return to play within a week of their injury, than the three out of four injured athletes who did not undergo such testing.

      The authors suggested three possible reasons:

      1. that the computerized tests are more reliable in guaging whether an athlete's cognitive functioning had returned to baseline than self-reporting by athletes of signs and symptoms (which, in the interest of a quick return to play, an athlete may downplay or fail to report altogether)(a hypothethesis which was confirmed in a more recent study; [6]
      2. that the use of such tests by those providing concussion management leads them to be more conservative in return-to-play decisions; and
      3. that neurocognitive testing is used more often in cases of severe concussions that require extended recovery times before return to play.

      Post-exercise neurocognitive testing recommended 

      2013 study [9] of concussed student-athletes who reported no symptoms and had returned to baseline on computerized neurocognitive tests taken before beginning the graduated return to sports protocol, found that more than a quarter (27.7%) exhibited declines in verbal and visual memory on the tests after moderate exercise. 

      The findings prompted the study's authors, led by sports concussion neuropsychologist Neal McGrath, Ph.D. of Sports Concussion New England, to recommend that neurocognitive testing become an "integral component of the athletic trainer's post-exertion evaluation protocol and that student-athletes should not be cleared for full contact activity until they are able to demonstrate stability, particularly in memory functioning, on such post-exertion neurocognitive concussion testing."

      "Given the unreliable nature of self-reported symptoms in athletes, a group typically motivated to return to play and minimize symptoms, the sensitivity of computerized neurocognitive testing to incomplete recovery and the importance of identifying any indicators that an athlete may not remain stable in his/her baseline functioning prior to return to contact sports action, post-exertion neurocognitive testing appears to be a logical tool to consider." 

      "Our thinking," said McGrath, "is that since exercise is known to cause recurrence of symptoms in some athletes who may not be fully recovered, and since neurocognitive testing has been shown to reveal persisting cognitive deficits in athletes who say or feel that they are symptom-free[6] any significant decline in post-exercise cognitive test scores for those athletes who have reached the point of feeling fully symptom-free, with resting neurocognitive scores that are back to baseline, would indicate that more recovery time is needed before returning to contact sports action. We would follow those athletes until their post-exercise neurocognitive test scores remain stable at baseline levels before clearing them to return to play."
