Collisions. Headers. Goalpost run-ins. Soccer athletes and fans can't help but wonder which elements contribute most to the frequency of concussions in the sport, particularly among young girls. Researchers have been collecting data in helmeted sports for many years using accelerometers embedded in head gear, but non-helmeted sports have presented obvious challenges. Impact data has provided some of the most critical science in the concussion field. As a result, the forces that players sustain in various contact sports are well-documented and found, in some cases, to be alarming. The latest addition to the data bank was the inclusion of an impact study on 7-and 8-year-old football players and the adult-sized forces they incurred during practices. Now the focus is turning to other sports, including soccer. A new study by researchers at Wayne State University, published in the Journal of the American College of Sports Medicine offers insight into head acceleration in girls' youth soccer (U14) during game play. HITS The Head Impact Telemetry System (HITS) used to measure the force impacts, was utilized in this study. Small accelerometers typically mounted inside helmets, transmit data wirelessly to researchers on the sideline. In this case, soccer headbands with the padding removed were outfitted with the instrumentation. Impacts over 10g, or 10x the force of gravity, were recorded and analyzed at a later time alongside corresponding video footage to determine the nature of the hit. For reference, a sneeze might be 3g, a fighter pilot might "pull" 9g during maneuvers, and high school football players regularly sustain hits ranging from 60-100g and higher, many without reporting concussion symptoms. A total of 24 girls participated in the study, conducted during scrimmages on grass fields. Scrimmages lasted 30 to 65 minutes each. None of the players suffered a concussion during the research. Results There were 47 header impacts and 20 non-header impacts observed during the study. Non-header impacts included collisions with another player, player falls, collisions with goalposts, and unintended collisions with the ball. Researchers found: - majority of non-header impacts (40%) were player-to-player collisions - most headers impacted the front of the head; the peak linear acceleration (force) recorded was 4.5g- greatest header force occurred on the right side of the head and was measured at 62.9g - most head impacts players sustained in one scrimmage was four - side headers resulted in greater forces than back headers - player collisions resulted in the highest number of nonheader impacts and had a maximum force of 56.7g - impacts from player falls measured a maximum force of 23.7g - a goalpost collision measured a maximum of 27.1g Researchers hypothesized that non-header impacts would exceed those from heading the ball, but that was not what the case. Many of the players experienced multiple impacts in a single scrimmage, the cumulative effects of such impacts within a short time frame are unknown. Conclusions Concussions can occur in any sport and amending equipment and making rule changes to decrease the frequency and severity of the injury depends on science. Soccer has emerged as the leading cause of sport-related concussions for young girls and researchers are working to unravel the reasons why. Hypotheses range from less neck strength, to hormonal differences to better reporting by females.

COLUMBUS, Ohio – There is no magic test to determine when an athlete is ready to get back into the game after they have suffered a head injury. Researchers have started using an interactive video game, a tool many athletes are already using in rehabilitation, to test balance for concussion assessment and management. The reliability of the video game for assessing athletes’ concussions has not been confirmed, but a study by a sports medicine researcher from The Ohio State University Wexner Medical Center may provide insight to the use of the Nintendo’s Wii Fit for concussion management. Team athletic trainers often determine whether an athlete has a concussion based on their physical examination, cognitive ability, self-report of symptoms and balance. "Student athletes love it because we have incorporated fun into their rehabilitation and concussion assessment," said Tamerah Hunt, director of research at the OSU’s Sports Medicine Concussion Program. “For many school districts, it is an affordable option and can be portable, making it convenient for sideline testing and travel with the team for away games.” Researchers from Ohio State and the University of Maryland are conducting baseline testing for concussion management in collegiate athletes, and will soon do the same among high-school athletes. Recent concussion guidelines suggest postural control is an important part of the assessment process, which makes balance an important piece of information in determining recovery from a head injury. “It’s not the perfect system, but can be considered as an option to provide basic objective information about balance,” said Hunt, whose previous research includes examining concussion recovery patterns among high school students in several states. “It’s another tool to have in our toolkit because determining when an athlete has recovered can be subjective,” Hunt admits. “Athletes are more likely to engage with a video game than to take another boring concussion test or admit they are still hurt,” said Hunt. “We currently base much of our assessment on an athlete telling us about their symptoms. The video game allows us to broadly analyze center of gravity, to help us be more objective.” Athletes participate in three different yoga poses as demonstrated on the Wii Fit game and are given a score which determines how well the athlete maintained center of balance. Baseline testing provides athletic trainers with an idea of how an athlete normally functions. If an athlete suffers a head injury at a later date, the athletic trainer can assess the balance of the athlete compared to their normal ability. According to Hunt, an athletic trainer must obtain the baseline measures to compare the athlete to themselves because everyone performs differently. Preliminary data suggests a moderate correlation to current methods used in concussion assessment, ranging from 0.75-0.82, depending on the stance. “Additional studies need to be performed to determine the long-term reliability of the measures and other factors associated with test scores, such as fatigue,” said Hunt. This is just the beginning of studies using alternative measures of balance assessment like the Wii Fit for concussion management. The National Collegiate Athletic Association concussion guidelines support using the video game as a postural assessment tool. It is not yet approved as a medical device by the Food and Drug Administration.

Reducing the number of concussions suffered by student-athletes is on the minds of many, including those that lead some of the most prestigious universities in the nation. Soon, following in the footsteps of changes made last year to Ivy League football programs, athletes in other sports may see the adoption of more protective measures as well. Ivy League football players saw significant changes in their practices last season after the eight presidents, two of whom are medical doctors, acted to reduce the number of impacts to their student-athletes' brains in an effort to minimize concussions. In July 2011 the Ivy League Concussion Committee developed a new set of regulations limiting full-contact practices to two per week, three less than allowed by the NCAA. In addition, of the preseason "two-a-days" only one can be full contact. Similar sport-specific regulations may be applied to other activities such as lacrosse, hockey, and soccer in the near future. “We are leading other conferences,” said Ivy League Executive Director Robin Harris. “I don’t know of any conference looking at this in the same manner that we are. We really see this as an area that we can be a leader in terms of the medical care safety of our athletes as well as in terms of the research we contribute to our collective understanding of concussions and athletics,” according to the The Harvard Crimson. Ivy League Deputy Executive Director Carolyn Campbell- McGovern was apart of this game change, “A lot of the recommendations from the football report were naturally going to be applied to other sports as well, particularly the education components, sideline testing components, and any other of those types of enhancement,” Campbell-McGovern said. Recommendations for each sport, lacrosse, soccer, and hockey, will likely be different. On Wednesday, the Ivy League Concussion Committee met in New York to discuss what changes will be made. The committee will also review recommendations made by each sport's subcommittee. Athletic trainers, including Harvard Head Athletic Trainer Brant Berkstresser, physcians, and administrators make up the concussion committee. It is co-chaired by presidents David Skorton of Cornell, and Jim Kim of Dartmouth. Harvard Medical School instructor and doctor at Children's Hospital Boston's Division of Sports Medicine, Michael J. O'Brien has ideas for change. He says he sees 300-400 concussions every month, 98 percent of them sports-related. “The bigger risk is the athlete who gets injured, flies under the radar a little bit and gets a hit a few more times in that game or in the next two or three games. The injuries to that athlete tend to be exponential, their threshold to injury is much worse, and the damage is exponential. Using computer based testing to get objective information rather than just reporting symptoms would help," O'Brien said.

Researchers at Nationwide Children's Hospital in Columbus, Ohio, found that of the 14,635 high-school sports injuries reported during the 2008-2010 school year, 13% were concussions. The majority of them were uncomplicated, in fact, 40% of the students who suffered concussions saw their symptoms disappear within three days. Most returned to play within three weeks, but a significant number -- about 25% -- returned to play the same day they were injured, a situation many state concussion laws are designed to address. "This improper practice was widespread," noted researchers Mallika Marar, Natalie McIlvain, Sarah Fields and R. Dawn Comstock, who found it in 12 of the 20 sports they studied. "This clearly violates the consensus statement on sports-related concussion, which recommends that no adolescent athlete who sustains a concussion should return to play on the day of the injury,"reported WPTV.com. Other findings included: Most common symptoms: headache (94.2%), dizziness (75.6%) and difficulty concentrating (54.8%) More than one: Eleven percent had suffered concussions before, highest rate of recurrence was boys' wrestling (20%) Most by number: football (47%) followed by girls' soccer (8.2%) Most common practices/games: games; exception was cheerleading, participants were 10x more likely to be hurt during practice Most by gender: boys; although concussions in girls' sports represented a higher number of overall injuries Most common occurrence: athlete-to-athlete contact; girls were more likely to suffer a concussion from striking the ground or being struck by another players' piece of equipment such as a hockey stick The study was published in the January edition of the American Journal of Sports Medicine.

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.

Q: What would you tell athletes about concussions? The NFL is in a state of evolution and recent changes will only make it safer for younger athletes. The league and the NFLPA (National Football League Players’ Association) have made huge strides to address the concussion issue, while maintaining the excitement of the game for both fans and players. It’s important that all athletes remember that you only get one brain and as we learn more about the long-term and adverse effects of contact sports and repetitive head injury, we know that smaller hits over the course of a career- even a high school career- can accumulate. Learn to recognize the symptoms of head trauma. You can have headaches or you might be slightly dizzy …these are all bearable and many athletes mask these symptoms by taking a Tylenol and then they go out and play again. But a concussion is not an ankle or shoulder injury…later in life you can have surgery on that ankle or have knee replacement surgery but you only get one brain. You can’t get a brain replacement. If you mask head trauma you can be risking increased problems in the future for Alzheimer’s or dementia. Head trauma has to be looked at very differently. Yes, in a way it’s a body part like a shoulder, but your brain must be treated very differently. You can ice and elevate an ankle but can’t do that with your brain. Real damage may show up later in life …and it’s not just football, it can happen in any sport. We used to look at toughness and playing through injuries as a badge of honor. That you were tough both mentally and physically and that continuing to play while hurt brought you the respect of your peers. But we need to change the culture now, and that starts with you. You need to believe that it’s OK to miss a game or a week or longer. If you do have to sit out, it means you were playing hard and you took one for the team. You shouldn’t feel ashamed. And if you care about your friends and your teammates, keep them from harm.https:// If you see a friend of yours doing something to hurt themselves, like playing with a concussion, step up and help them. You’re doing them a huge injustice by allowing them to continue to play. You are your brother’s keeper. Become a hero in their life and help them realize what they probably know deep down inside anyway. Someday they’ll look back and know what you did for them, and they’ll respect you more, later in their lives. Be a leader and help change the game. Help create a new norm.

"Short term memory's not good," Jim McMahon, former Chicago Bears quarterback and two-time Super Bowl champion tells ESPN. "I won't remember a lot about this interview in about 10 minutes." McMahon and his girlfriend give a rare look inside the daily struggles he says were a result of repeated blows to the head incurred during his 15-year NFL career. McMahon and hundreds of other former NFL players are suing the league for allegedly concealing information about the risk of concussions. ESPN Outside the Lines -- Taking Its Toll (8:12)(video) The 52-year-old McMahon says he suffered three documented concussions during his career, impacts significant enough that he was unaware of his surroundings. Now he has good days and bad days according to his girlfriend, Laurie Navon, who has programmed the GPS in his car with their home address in case he gets lost. He repeatedly purchases the same books on his e-reader. The Chicago Bears selected McMahon in the first-round of the 1982 NFL Draft where he won the starting quarterback position as a rookie. McMahon led the Bears to a Super Bowl victory in 1985, where he became the first quarterback in the championship's history to rush for two touchdowns. He returned to win the Super Bowl a second time as a Green Bay Packer in 1996. On Oct. 12, 1988 the Chicago Tribune reported that McMahon had been evaluated by an athletic trainer on the sideline who said, "He had a concussion, but it cleared by halftime." The NFL has much stricter policies and standards regarding head injury today, as more information on concussions has become available.

Wisconsin governor Scott Walker signed youth concussion legislation into law today at Lambeau Field in Green Bay. Support for the bill came from physicians, student-athletes, the NFL's Green Bay Packers and other organizations. NFL Commissioner Roger Goodell has exhibited an unwavering committment to the adoption of concussion legislation nationwide, starting with the Washington state concussion law named after middle school football player Zackery Lystedt, who was injured during a game in 2006. Like the Lystedt Law, Wisconsin's concussion law calls for the removal of any athlete suspected of having suffered a concussion and requires a player to obtain written medical authorization before resuming activity. The new law also requires the state Department of Public Instruction to work in conjunction with the Wisconsin Interscholastic Athletic Association to develop guidelines and education standards for parents, coaches, and athletes.

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. The UPMC clinicians and researchers treat more than 13,000 patients a year, and published more than 75 clinical research studies in peer-reviewed scientific journals. About ImPACT ImPACT™ (Immediate Post-Concussion Assessment and Cognitive Testing) is an independently validated and researched concussion-evaluation system that has become the most widely used in the United States. Co-founded in the early 1990s by Drs. Mark Lovell, Joseph Maroon and Michael “Micky” Collins, who have a proprietary interest in ImPACT Applications, Inc., ImPACT is a 20-minute test that is a standard tool used as part of comprehensive clinical concussion management adopted across the NFL, NHL, NBA, Major League Baseball, college and high-school athletics -- with roughly 3 million people tested.
