Concussion Spectrum in College Athletes Wearing Helmets: 'Not So Simple,' Say Researchers

What does it mean to have a head concussion? Much has been written in recent years about the short- and long-term consequences of concussions sustained in sports, combat, and accidents. However, there appear to be no steadfast rules guiding the definition of concussion: the characteristics associated with this type of traumatic head injury have shifted over time and across medical disciplines. Within the context of a larger longitudinal investigation of the biomechanical factors in play that correlate with concussions in collegiate helmeted contact sports, researchers in New England and Virginia used data they obtained to investigate which signs, symptoms, and clinical histories were used by athletic trainers to define concussion in individual players. The investigators found that a heterogeneous collection of acute clinical characteristics currently exists for those events diagnosed as concussion in college athletes engaged in contact sports. Together with her colleagues, Dr. Duhaime, Director of Pediatric Neurosurgery and of Neurotrauma and Intensive Care in the Neurosurgical Service of Massachusetts General Hospital, examined concussions diagnosed in athletes participating in helmeted contact sports (football and ice hockey) at three universities: Dartmouth, Brown, and Virginia Tech. Both male and female athletes participated in the study. The students' helmets were outfitted with Head Impact Telemetry (HIT) System™ technology to record and measure peak linear and angular acceleration of impacts. The helmets were worn during practice sessions and games throughout two to four seasons. The investigators did not attempt to influence how trainers and team medical personnel defined concussion operationally, but instead relied on the clinical characteristics deemed indicative of concussion by the universities' athletic departments. More than 486,000 head impacts were recorded in 450 athletes, and concussion was diagnosed in 44 of these athletes (48 concussions) by team medical staff. Unlike concussions more often diagnosed in emergency departments, where a single, identified contact event leads to a loss of consciousness or other clear alteration in consciousness, most diagnoses in this sports setting were based on self-reports by athletes, and only a few were based on changes in athletes' clinical conditions that were observed by others. Thirty-one concussions could be directly associated with a specific impact, whereas a relationship with a specific impact could not be verified in the other cases of concussion. Only half of the athletes noted symptoms immediately after a contact event; in many athletes, the onset of symptoms was delayed. The most common reported symptoms were mental clouding, headache, and dizziness; only one case involved a loss of consciousness. The diagnosis of concussion by trainers often occurred in an even more delayed fashion: the diagnosis was made immediately after the event in 6 cases and at a later time in the other cases (median 17 hours postinjury). In general, the mean peak linear and angular accelerations for specific impact events that could be directly linked to concussions tended be in the high percentiles for the sports examined; however, there was considerable variability in the ranges of these measurements (mean peak linear acceleration 86.1 ± 42.6 g [range 16.5.9 g], mean peak angular acceleration 3620 ± 2,166 rads/sec2 [range 183,589 rads/sec2]). The variety of signs and symptoms, the imprecise timing of symptom appearance and relationship to a specific contact event, the lack of externally observed findings, and the broad ranges of the linear and angular accelerations of the impacts that coalesce in a diagnosis of concussion in college sports make it difficult to identify predictors of acute, intermediate, and long-term risks of adverse consequences resulting from sports-related head impacts. By describing the heterogeneity inherent in diagnoses of concussion as a "concussion spectrum," the authors point out the need for renewed efforts to determine which factors -- clinical, mechanical, genetic, or others -- influence outcomes in patients with single as well as repeated head impacts. The authors point out that while a clinical diagnosis is important to protect players from additional and potentially more serious consequences, it is also possible that athletes who do not receive the diagnosis of "concussion" may be at similar risk. Likewise, it is possible that some players who receive a diagnosis of concussion do not fall into a high-risk category for specific consequences. The authors note that there is still much to be learned, and that the terminology in use can sometimes oversimplify a more complex set of processes that still need to be teased apart. In their response to an accompanying editorial, they state, "By carefully characterizing exactly what we are talking about and by continued investigation, which will take more time ... , neurosurgeons and others will be best positioned to offer effective treatments and to advocate knowledgeably for appropriate injury-prevention strategies."

The Dynavision D2 ™

The Dynavision D2 ™ is an FDA cleared medical device with a long history concerning sports performance enhancement and an even longer history concerning neuro visual rehabilitation of stroke and brain injured patients. Physical medicine rehabilitation practitioners have used it to train brain injured patients to improve hand eye coordination since the 1980s. With a pedigree from the neuroscience community concerning rehab and from the sports community for improving performance it was a logical fit that the D2 ™ be applied to the management of the athlete with a concussion. The Dynavision D2 ™ is a light board with 64 lights mounted in a board along with a small screen. The primary task is to hit the red or green lights. It assesses speed and coordination. When the computer screen and lights are used together there are numerous tasks the athlete can be asked to do. Several universities and professional sports organizations have adopted the Dynavision D2 ™ as part of the concussion management program, and for good reason. The Dynavision D2 ™ can be used as part of baseline testing. The results of the baseline tests are used for comparisons should a concussion occur. These same athletes may also train their eye hand coordination using the Dynavision D2 ™ for performance enhancement. This means the device is familiar to them and true baseline and performance parameters can be obtained. After a concussion, the Dynavision D2 ™ can be used as part of a traditional neuro cognitive examination and monitoring program. The baseline Dynavision D2 ™ results can be compared to repeat tests to see if deficits are present. Further, programs designed to assess multiple brain cognitive parameters can be performed in just a few minutes. The three tests assess: eye-hand coordination while multi-tasking, memory and cognition, cognition and executive functions. Observing the subject and noting their scores allows for an assessment of their concussion status. One of the strengths of the Dynavision D2 ™ is that it has an established cadre of programs that anyone can use. These programs can be used for rehab, prehab and diagnostics. Plus it has a relatively intuitive program option that allows more experienced practitioners and ADT trained individuals to design their own programs to meet their needs. This means that the Dynavision is a highly flexible and adaptable platform. Every person who works with athletes, injured athletes and neuro patients knows that each person is different and unique; training and rehab methods need to be personalized. Fortunately the Dynavision allows us to customize the programs to address the needs of the patient. There are numerous anecdotes where a patient who expresses a deficit that he/she is having to a rehab person who can write and try a program to help that patient during that very rehab session. One of my patients at the concussion clinic in theUniversityofCincinnatiwas injured in a wind storm. During her baseline neuro exam, we utilized the tests mentioned above and additional tests based on her specific results. The D2 was able to demonstrate the patient was unable to multi-task, making numerous math errors on simple 1 digit additions. In addition, based on a general neuro exam, the patient exhibited deficiencies in ocular motor, memory and executive function. This patient specifically benefited from the D2 as part of her neuro exam because the D2 gave measurable, unbiased results. The results of the exam were utilized to incorporate D2 training into her rehab program to improve binocularity, reaction time, multi-tasking, and cognition skills. In my opinion, without using the D2, this patient’s rehab would not have been as successful and it could have been possible to overlook subtle deficiencies that D2’s measurable results are able to track. In the center of the Dynavision D2 ™ is a tachistoscope; or small computer screen. This screen is used in several of the evaluation and rehabilitation methods. It adds tremendous flexibility to the system because it can be used to add tasks to what the subject is required to do. With the tachistoscope the patient can now be required to do a hand-eye task as well as reading or other task from the screen. This allows for multitasking to be performed and adds to the flexibility and strength of the Dynavision D2 ™ as a tool to manage the concussion patient. Repeating the evaluations on the Dynavision D2 ™ can be used as part of quantitative monitoring of the subjects as they progress through concussion rehab. The Dynavision produces reliable numbers that reflect the subjects’ performance or highlights deficiencies. When the Dynavision D2 ™ is used as part of the rehab training it becomes a cornerstone in the patient’s care and the patient can see, based on their own results, how well they are doing. Rehabilitation methods can be tailored to the needs of the patient and with many years of experience from the stroke and brain injury literature there are numerous options for the Dynavision D2 ™ to aid in a concussion rehabilitation program.

Female Athletes Show No Difference from Males in Neurocognitive Testing After Suffering Sports-Related Concussions

As female participation in sports grows rapidly, there is a popular notion that there are gender-related differences in athletes' responses to sports-related concussion, and prior research has supported these gender discrepancies. However, a Vanderbilt University Medical Center study, conducted to review symptoms and neurocognitive findings in male and female high school soccer players, shows no gender-related differences. "There has been good data that suggests girls score worse on neurocognitive testing following a sports-related concussion. Our hypothesis was that a tightly-controlled study would replicate what others have shown previously," said Scott Zuckerman, M.D., a neurosurgery resident who conducted the study with colleagues at the Vanderbilt Sports Concussion Center. The researchers selected 40 male and 40 female concussed patients who were matched, as closely as possible, for age, medical/psychiatric history, years of education, lack of special education assistance, history of psychiatric treatment, number of prior concussions, timing of pre- and post-concussion testing, and sport (all engaged in soccer). This is the first study to control for type of sport played when looking a gender differences, Zuckerman said. "Prior studies have used mixed groups of athletes from a variety of sports. We suspected that since concussions vary from sport to sport (i.e., helmets vs. none, varying biomechanical forces, etc.), if the variable of sport was controlled, gender differences might disappear." The only significant gender-related difference they could identify was that female soccer players reported a greater number of symptoms post-concussion. There were no significant differences in post-concussion neurocognitive scores. "We were somewhat surprised and were not sure what to expect in such a tightly controlled population," Zuckerman said. "Our hypothesis was that females would experience greater levels of acute, post-concussive, neurocognitive impairment than males, fitting with what most of the prior literature says, but we found virtually no difference between males and females." Zuckerman said this is a significant finding for the treatment of sports-related concussion. "When we see any child after concussion, we don't want to make snap decisions based on gender. Gender may not be as big a modifying factor as previously thought." This study is the first from V-SCoRe, or Vanderbilt Sports Concussion Research. Collaborators include Allen Sills, M.D., Gary Solomon, Ph.D., Andrew Gregory, M.D., Alex Diamond, D.O., and Jonathan Forbes, M.D., and medical students Mitchell Odom and Young Lee. "This effort is just getting off the ground, and we're investigating many more modifying factors in concussion, including age, sleep, symptoms, prior history of attention deficit disorder," Zuckerman said. "Our goal is to create new knowledge in this area and help providers better understand when a young athlete can return to play safely."

Does CTE infect neuron to neuron?

NFL Hall of Famer "Iron Mike" Webster's life ended in 2002 when he suffered a heart attack at age 50. Four Super Bowl rings, nine Pro Bowls, and voted to the NFL's all-time team in 2000, the driven, ultra-competitive Steelers' center drifted into a life of drug use, homelessness, and enormous suffering after retiring in 1988. In 2005, his son Garrett told ESPN that the only way his father could get to sleep was to taser himself into unconsciousness. Former teammates and friends offered assistance over the years but it wasn't enough. After Webster's death, forensic neuropathologist Dr. Bennet Omalu was determined to find neurological reasons for his cognitive decline. Seventeen years in the NFL at a time when safety precautions and concussion awareness were both minimal had resulted in thousands of impacts to his head. Though his brain looked normal at autopsy, Omalu pressed on until he found the abnormalities that we now call Chronic Traumatic Encephalopathy, or CTE. CTE and Alzheimer's CTE and Alzheimer's are both “neurodegenerative diseases.” That is, they are brain diseases that result in the progressive destruction of brain cells, eventually leading to cognitive, behavioral, and other impairments. Both Alzheimer’s and CTE can only be accurately diagnosed postmortem through a neuropathological examination of the brain and their progression has remained elusive. But clues about how Alzheimer's spreads from neuron to neuron are now emerging. Whether the same process of progression applies to CTE is currently unclear. Photo: Alzheimer's infects from neuron to neuron The inexorable spread of Alzheimer’s disease through the brain leaves dead neurons and forgotten thoughts in its wake. Researchers at Linköping University in Sweden are the first to show how toxic proteins are transferred from neuron to neuron. Through experiments on stained neurons, the research team – under the leadership of Martin Hallbeck, associate professor of Pathology – has been able to depict the process of neurons being invaded by diseased proteins that are then passed on to nearby cells. “The spread of Alzheimer’s, which can be studied in the brains of diseased patients, always follows the same pattern. But until now how and why this happens has not been understood,” says Hallbeck, who along with his research group has now published their results in The Journal of Neuroscience. The illness starts in the entorhinal cortex – a part of the cerebral cortex, and then spreads to the hippocampus. Both of these areas are important for memory. Gradually, pathological changes take place in more and more areas of the brain, while the patient becomes even sicker. Two proteins have been identified in connection with Alzheimer’s: beta amyloid and tau. Normally tau is found in the axons – the outgrowths that connect between neurons – where it has a stabilising function, while beta amyloid seems to have a role in the synapses where the neurons transfer signal substances to each other. But in Alzheimer’s patients, something happens with these proteins; autopsies reveal abnormal accumulations of both. Why they become abnormal is still unknown, but what is known is that it’s not the large accumulations, or plaques, that damage the neurons. Instead, smaller groups of beta amyloid – called oligomeres – seem to be the toxic form that gradually destroy the neurons and shrink the brain. “We wanted to investigate whether these oligomeres can spread from neuron to neuron, something many researchers tried earlier but didn’t succeed,” Hallbeck says. The study was inaugurated with an experiment on neuron cultures, where researchers injected oligomeres stained with a phosphorescent red substance called TMR using a very thin needle. The next day the neighbouring, connected neurons were also red, which showed that the oligomeres had spread. To test whether a sick neuron can “infect” others, they conducted a round of experiments with mature human neurons stained green and mixed with others that were red after having taken up stained oligomeres. After a day, approximately half of the green cells had been in contact with a few of the red ones. After two more days, the axons had lost their shape and organelles in the cell nucleus had started to leak. “Gradually more and more of the green cells became sick. Those that hadn’t taken up the oligomeres, on the other hand, weren’t affected,” Hallbeck says. The study is a breakthrough in understanding Alzheimer’s and its progress. If a way of stopping the transfer can be found, it could lead to a more effective inhibitor against the disease.

Progesterone seems to protect neurons after injury

It is not yet known why girls suffer concussions at a higher rate than boys. The most prevalent theories range from lesser neck and upper body strength, to better reporting among females, to hormonal differences. Researchers at Emory University in Atlanta are currently in the third phase of a clinical trial designed to determine if the hormone progesterone, normally associated with female reproductive processes, can protect damaged neurons. Administered within four hours of the injury and lasting for three days, results of the treatment have been positive so far. Although catastrophic injuries in sports are rare, the question regarding applicability of a related treatment for concussion remains open. Pilot study highlighted efficacy Every 15 seconds, someone in the United States sustains a significant traumatic brain injury. Approximately 2 million adults and children in the United States suffer from traumatic brain injuries each year - leading to 50,000 deaths and 80,000 new cases of long-term disability, according to the Centers for Disease Control and Prevention. Despite the enormity of the problem, scientists have failed to identify effective medications to improve outcomes following a traumatic brain injury. Emory researchers, however, concluded in an earlier pilot clinical trial that giving progesterone to trauma victims shortly following brain injury appears to be safe and may reduce the risk of death and long-term disability. Their previous three-year study, called ProTECT I (Progesterone for Traumatic brain injury--Experimental Clinical Treatment), enrolled 100 participants at Grady Memorial Hospital. It was designed to evaluate whether progesterone can be administered intravenously in a safe and reliable way. "We found evidence that progesterone is not only safe for use in patients suffering from traumatic brain injuries," says Wright. "We also found a 50 percent reduction in mortality in those patients treated with progesterone. Even though this was a small pilot study, we found signs that progesterone improved functional outcomes and reduced disability in patients with moderate brain injury. "By expanding our test sites to 17 major trauma centers across 15 states and enrolling more than 1,000 patients, we hope to confirm these preliminary findings and determine if progesterone benefits victims of acute traumatic brain injury," says Wright. Progesterone common in males and females Progesterone is naturally present in small but measurable amounts in the brains of males and females. Human brain tissue is loaded with progesterone receptors. Laboratory studies suggest that progesterone is critical for the normal development of neurons in the brain and exerts protective effects on damaged brain tissue. Donald G. Stein, PhD, Asa G. Candler Professor of Emergency Medicine, Emory School of Medicine, and director of Emory's Department of Emergency Medicine Brain Research Laboratory, pioneered discoveries regarding the effect of progesterone following traumatic brain injury - first discovering the neuro-protective properties of progesterone in the laboratory more than 25 years ago. "The results that we are now seeing, and hope to continue validating, are an incredible and gratifying reward for more than 25 years of concentrated research," says Stein. "My work first started when I began to notice evidence that women tended to respond to treatment and recover better than men after suffering from brain injury and stroke. Many people do not realize that it's not just a female hormone; both men and women produce progesterone directly in the brain, as well as other tissue. "Ultimately, we learned that progesterone basically does in brain injuries what it also does during fetal development - protect cells and tissue," says Stein. "To now witness the translation of this laboratory research into a treatment that may have life-saving benefits is breathtaking."

Girls' lacrosse; a referee's view

As a new womens' lacrosse referee I initially had mixed feelings about the ongoing debate on the use of helmets in play. Listening to the discussion in referee training sessions that stressed the finesse of the game and the need of the referee to control or slow down play, verses the struggle I felt as a person having a medical degree and realizing the potential hazards of brain injuries, I tried to see both sides. Some people think that helmets will make the game more physical. But after my first official day as a referee standing on the sidelines watching my daughter’s middle school team begin their game, my beliefs became clear. Female lacrosse players need to wear helmets. During the first eight minutes of the game there were three injuries, one related to a child’s head and neck. This player had been checked from behind causing her neck to snap back. She then fell and hit her head on the turf. I witnessed every parent’s/referee’s/coach’s nightmare: a player down and seizing. To my dismay, this player returned to play in less than three weeks and went on to have another concussion and seizure. She is now barred from impact sports for the rest of her life. What I found out about my local school district surprised me and motivated me to try to educate parents and give people the best information possible. After speaking to the athletic trainers in my school district, I was made aware that high school students are given baseline concussion testing but younger players are not. We are now in the process of offering that testing to younger players. Also, while coaches can have in-person or online concussion training it seems that more could be done to help the coaches and parents become more informed about concussions. There are numerous issues that could explain the high incidence of concussions in women's lacrosse. One might be to consider the nutrition and health of girls playing the game today. Both men and women today are better nourished and physically stronger, faster and more powerful than the players of previous years. This has created a weight imbalance as some players can actually outweigh others by a large margin. The physics of combining speed and extra mass can lead to a dangerous combination. Equipment has also evolved to allow for lighter and faster sticks, causing unintended hits in some instances, I'm sure. Another factor is the increase in new players due to the popularity of the sport. Putting players of different skill levels in the same game can set up a difficult dynamic. It is important for players to be aware of their body position in space and reference to other players. This is a skill that comes with time and coaching. Coaching is another aspect of the game that helps teams work together better and control the speed of their game. Neck strengthening exercises can decrease the whiplash motion often caused by a hit to the cranial region. As for me, I have now completed my first season as a referee. I feel that helmets and proper body equipment in womens' lacrosse will make the game safer for everyone. My feeling is that there are too many factors that increase the potential for head injuries and we should mitigate them as best we can. While I realize helmets do not prevent concussions, I do believe they would be helpful to protect young women from unintended hits to the head. Dr. Lori McGowan is an Adjunct Professor of Biology at Harrisburg Area Community College in Harrisburg, Pennsylvania.

UPMC study; early indicators of prolonged concussion recovery

PITTSBURGH – The unpredictable nature of concussions is one of the most frustrating factors to the millions of sufferers each year, but early neurological indicators and symptoms can predict a protracted healing time in certain cases, according to specialists at UPMC and the University of Pittsburgh School of Medicine. “It’s a highly variable injury with a variety of outcomes,” said Michael “Micky” Collins, Ph.D., director of the UPMC Sports Medicine Concussion Program and co-investigator of the Pitt/UPMC study published in the February issue of Neurosurgery. “We see some patients who take a day or two to recover, and some who take a year or longer to recover. If clinicians had a way of determining within two days of injury who’s going to take a month or longer to recover, that’s a very important piece of information to have. It’s a game-changer.” The study, one of the first to examine concussion prognoses, showed that specific neurocognitive “cut-off” scores derived from ImPACT™ (Immediate Post-concussion Assessment and Cognitive Testing) improved clinicians’ ability to predict which sports-related concussions could take longer –- as much as five times longer -- to rehabilitate than others. They found, in as many as 85 percent of the cases, the scores could warn athletes, parents, coaches, schools, teams and health professionals when a concussion is likely to take on average a month to heal. Such an objective prognosis could help clinicians to better prepare a treatment plan, arrange academic accommodations for students and set tangible expectations for return to play and school, Dr. Collins said. The study reviewed 108 high-school football players who were given ImPACT tests within a median of two days after their concussions. Fifty boys experienced a recovery lasting, on average, 33 days before returning to play, and those longer rehabilitations could be forecast by specific “cut-off” scores in ImPACT Visual and Processing Speed testing. Migraine and cognitive symptoms also appeared to have predictive power. Study participants who scored above the threshold levels recovered within a median of seven days. “We’ve established statistical ‘cut-offs’ that indicate people who take a month or longer to recover,” Dr. Collins said. “Eighty percent of concussed people recover inside of three weeks. This prognostic information allows us to develop a risk profile of athletes who don’t recover well from this injury. Other study authors include Brian Lau, B.S., from the Pitt School of Medicine, and Mark Lovell, Ph.D., the Concussion Program’s founding director who retired from UPMC last summer. About UPMC Sports Medicine Cohttps://n Program The first-of-its-kind UPMC Sports Medicine Concussion Program, established in 2000, is the largest multi-disciplinary clinical and research program that focuses on the diagnosis, evaluation and management of sports-related concussion in athletes of all levels.

Warning: examine concussion equipment claims before purchase

KANSAS CITY, Mo. -- The National Operating Committee on Standards for Athletic Equipment (NOCSAE) issued a warning to athletes and parents of athletes to thoroughly understand the extent of protection provided by – or not provided by – athletic equipment worn while playing sports. This warning follows claims made by several companies that products such as head bands, supplements or mouth guards reduce the incident of concussion. NOCSAE issued the warning at the onset of its summer meeting held this year in Kansas City. NOCSAE is an independent organization with the dual purpose of setting standards for the performance of athletic equipment and funding research necessary to advance the science of sports. Through NOCSAE's independent process, physicians, academic researchers, coaches, trainers and manufacturers come together to establish standards based on accepted science and reliable data. "Parents, athletes and coaches are becoming more informed about concussions, and this increased awareness is vitally important to advancing athlete safety. But it also creates a demand for quick solutions. Unfortunately there are quick solutions offered for sale which have neither scientific nor medical support that validate their claims to prevent or reduce concussions," said Mike Oliver, NOCSAE executive director. "Any device or supplement promoted as being able to prevent, diagnose or cure a concussion must be supported by scientific data and peer-reviewed research. Currently there is no definitive scientific research linking mouth guards, head bands, supplements or other specialty products to a reduction in concussion risk or severity. For companies to suggest otherwise misleads athletes, parents and coaches into a dangerous false sense of protection against concussion. NOCSAE warns athletes and parents of athletes to get the facts about sports equipment and concussion protection and not rely solely on marketing and promotional materials when making equipment decisions." NOCSAE does not maintain any standards for such products, and, therefore, no such products can be claimed as meeting the NOCSAE standards. While protective equipment certified to the NOCSAE standard play an incredibly important role in protecting athletes on the field of play, they should be not the primary approach to protecting against concussion. Learning to avoid unnecessary head impacts, reporting concussion symptoms to a coach or parent and following trained medical management decisions about when a concussed athlete can return to play are far more likely to prevent a concussion or reduce the chance of chronic problems that may be related to untreated concussions. For more information, please visit www.nocsae.org. About NOCSAE NOCSAE, the Nhttps:// Operating Committee on Standards for Athletic Equipment, is an independent and nonprofit standard-setting body with the sole mission to enhance athletic safety through scientific research and the creation of performance standards for protective equipment. Formed in 1969, NOCSAE is a leading force in the effort to improve athletic equipment and, as a result, reduce injuries. NOCSAE efforts include the development of performance and test standards for football helmets and facemasks, baseball and softball batters and catchers helmets, baseballs and softballs, ice hockey helmets, soccer shin guards, lacrosse helmets and facemasks and polo helmets. NOCSAE is comprised of representatives from a number of groups which have an interest in athletic equipment – including manufacturers, reconditioners, athletic trainers, coaches, equipment managers, sports medicine and consumer organizations. These diverse interests have joined forces in an attempt to arrive at a common goal of reducing sports-related injuries.

Pop Warner limits contact practices

Pop Warner, the nation's largest youth football organization announced Tuesday it is taking steps to eliminate hits to the head and reduce the number of concussions suffered by players. Chairman of the Pop Warner medical advisory board, Dr. Julian Bailes said, "The impact of head-to-head contact causes the most severe concussions, so we felt it was imperative that Pop Warner take a proactive approach and limit contact in practices. We're trying to take away all at once the head-to-head contact in practice." Pop Warner is the nation's oldest and largest youth football, cheerleading and dance program, with over 400,000 members ranging in age from 5-14. Starting in August many teams practice nine hours a week until Labor Day when most are then shortened to six hours. Research has shown that some of the hardest hits and many concussions occur during practice, not games. New rules prohibit head-to-head hits and limit contact in practices to 40 minutes a day. Full-speed head-on blocking and tackling drills where players line up more than three feet apart are no longer allowed. In April 2012, veteran journalist and former Dateline co-anchor, Stone Phillips produced a report entitled, "Hard Hits, Hard Numbers," detailing a Virginia Tech study on head impacts in youth football. Accelerometers placed inside 7- and 8-year-old players' helmets recorded hits from 15g-100g, surprising researchers. Previously, many believed that players that age did not have the speed or strength to deliver hits of those magnitudes. Over 4 million sports- and recreation-related concussions occur each year in the United States and more than half of those are suffered as a result of football, reported NBC News.

The Dynavision D2 ™ is a light board with 64 lights mounted in a board along with a small screen. The primary task is to hit the red or green lights. It assesses speed and coordination. When the computer screen and lights are used together there are numerous tasks the athlete can be asked to do.

Several universities and professional sports organizations have adopted the Dynavision D2 ™ as part of the concussion management program, and for good reason. The Dynavision D2 ™ can be used as part of baseline testing. The results of the baseline tests are used for comparisons should a concussion occur. These same athletes may also train their eye hand coordination using the Dynavision D2 ™ for performance enhancement. This means the device is familiar to them and true baseline and performance parameters can be obtained.

After a concussion, the Dynavision D2 ™ can be used as part of a traditional neuro cognitive examination and monitoring program. The baseline Dynavision D2 ™ results can be compared to repeat tests to see if deficits are present. Further, programs designed to assess multiple brain cognitive parameters can be performed in just a few minutes. The three tests assess: eye-hand coordination while multi-tasking, memory and cognition, cognition and executive functions. Observing the subject and noting their scores allows for an assessment of their concussion status.

One of the strengths of the Dynavision D2 ™ is that it has an established cadre of programs that anyone can use. These programs can be used for rehab, prehab and diagnostics. Plus it has a relatively intuitive program option that allows more experienced practitioners and ADT trained individuals to design their own programs to meet their needs. This means that the Dynavision is a highly flexible and adaptable platform. Every person who works with athletes, injured athletes and neuro patients knows that each person is different and unique; training and rehab methods need to be personalized. Fortunately the Dynavision allows us to customize the programs to address the needs of the patient. There are numerous anecdotes where a patient who expresses a deficit that he/she is having to a rehab person who can write and try a program to help that patient during that very rehab session.

One of my patients at the concussion clinic in theUniversityofCincinnatiwas injured in a wind storm. During her baseline neuro exam, we utilized the tests mentioned above and additional tests based on her specific results. The D2 was able to demonstrate the patient was unable to multi-task, making numerous math errors on simple 1 digit additions. In addition, based on a general neuro exam, the patient exhibited deficiencies in ocular motor, memory and executive function. This patient specifically benefited from the D2 as part of her neuro exam because the D2 gave measurable, unbiased results. The results of the exam were utilized to incorporate D2 training into her rehab program to improve binocularity, reaction time, multi-tasking, and cognition skills. In my opinion, without using the D2, this patient’s rehab would not have been as successful and it could have been possible to overlook subtle deficiencies that D2’s measurable results are able to track.

In the center of the Dynavision D2 ™ is a tachistoscope; or small computer screen. This screen is used in several of the evaluation and rehabilitation methods. It adds tremendous flexibility to the system because it can be used to add tasks to what the subject is required to do. With the tachistoscope the patient can now be required to do a hand-eye task as well as reading or other task from the screen. This allows for multitasking to be performed and adds to the flexibility and strength of the Dynavision D2 ™ as a tool to manage the concussion patient.

Repeating the evaluations on the Dynavision D2 ™ can be used as part of quantitative monitoring of the subjects as they progress through concussion rehab. The Dynavision produces reliable numbers that reflect the subjects’ performance or highlights deficiencies. When the Dynavision D2 ™ is used as part of the rehab training it becomes a cornerstone in the patient’s care and the patient can see, based on their own results, how well they are doing. Rehabilitation methods can be tailored to the needs of the patient and with many years of experience from the stroke and brain injury literature there are numerous options for the Dynavision D2 ™ to aid in a concussion rehabilitation program.
