Impact Indicator measures force and duration from chinstrap microsensor

PRIMEAU BELIEVES HELMET DEVICE CAN CUT DOWN ON CONCUSSIONS

This story sourced from- TORONTO –“http://www.tsn.ca/nhl/teams/players/?name=keith+primeau”>

Keith Primeau is hoping a little green light can help lessen the debilitating effects of concussions that he knows far too well. The former NHLer, whose career was cut short by post-concussion syndrome in 2006, is helping promote the Impact Indicator, a device with a small light that’s worn as part of a chin strap and measures the impact of a blow. A green light is normal. A dangerous hit and the light will flash red. “Everything to this point has been subjective, we go to the sideline and ask our coach or trainer or parent whether they feel we’ve suffered through a possible concussive event,” said Primeau. “With this, as a coach, it would enable me to remove a player from competition, to err on the side of caution, to see if in fact (a concussion) was the case.” Primeau hosted a media conference Monday to spread the word about concussion education, and Impact Indicator was only part of his message. It’s also part of the information he and former hockey player Kerry Goulet provide on their website — http://www.stopconcussions.com. Primeau, 39, played 16 years in the NHL before his fourth documented concussion — while with the Philadelphia Flyers — forced him to retire. He still feels crippling effects: headaches, head pressure, dizziness and fatigue. “I’m still not able to exercise or exert high energy levels, because it makes me lightheaded,” said the six-foot-five former centre. He coaches his sons Camden and Corey in Philadelphia, and both teams will be outfitted with the Impact Indicator, which costs about $100 per unit for a season. The Toronto Bulldogs, including Mason Primeau Keith Primeau brother Wayne — will also wear the device, which is a padded chin guard with a tiny LED light. The microsensor measures the force and duration of a hit. A red light means a level of impact that has a 50 per cent or higher probability of concussion. Because concussion symptoms often develop over several hours, a red light takes out the guesswork about whether to remove a player from the game before another more devastating blow. Primeau noted the hit on Buffalo’s Ryan Miller in Sunday’s game against Boston. The Sabres goalie was hit midway through the first period, stayed in the game until early in the third period and was later diagnosed with a concussion. Chris Circo, president of U.S.-based Battle Sports Science which developed the device, said thousands of football players in the U.S. have started wearing it since it became available for purchase last month. It’s only now available for sale for hockey players. “What we’re trying to do in this fight is put a different set of eyes out on the field, out on the ice, wherever you play your game, to help people understand that high level impacts are more likely to cause head trauma,” Circo said. “These are lifelong effects from head injuries, they’re not a week, they’re not two weeks. They can be forever.” Texans wide receiver Derrick Mason wears the device along with several of his Houston teammates, said Circo. The target users, however, are young athletes who as pro players will be far more reluctant to wear anything that forces them to the sideline, he said. “Athletes are notorious. . .99 per cent are not going to pull themselves out of game,” he said. Players on the West Mall Lightning, a midget triple-A team in the Greater Toronto Hockey League, are wearing the device. “When you get hit, if you get hit hard enough, it makes you feel safer because you know if you’re hurt or not so you can go get help if you need it, said Ryan Kosmynka, a 15-year-old player on the Lightning. “Normally it’s like: do I stay out or do I go see if I’m hurt or not?” Kosmynka said the device doesn’t feel noticeably different. It doesn’t affect field of vision. Numerous speakers took the podium at Monday’s event at a Toronto restaurant next door to the Hockey Hall of Fame. Doctors discussed the importance of baseline testing, while former athletes talked about battling concussion symptoms. Goaltender Paul Rosen, who won gold with Canada’s sledge hockey team at the 2006 Turin ParaOlympics, said dealing with the loss of his leg in 1999 was easy compared to his post-concussion symptoms. “Losing my leg was an absolute joke in the way I dealt with it compared to what I’m dealing with on a day to day basis,” said Rosen, who suffered a concussion after a sled hit him in the head. “Thing was, they told me to suck it up. We have to get out of this mentality, whether kids are 10 years old or playing professional hockey, is get out of that mentality of suck it up. “One hit to the head is one hit too many.” Primeau and Goulet also announced the introduction of a scholarship fund to help concussed athletes, in memory of Eric Pelly. The Pittsburgh athlete was 18 when he died in 2006 after suffering a concussion in a rugby game.

With concussions becoming a growing concern among athletes at both pro and Joe levels, new products are on the way to help coaches and parents better determine when a player might have suffered one. Over the next few weeks, a U.S. company called Battle Sports Science is making its Impact Indicator available throughout Canada and the United States. It is a sensor that is fastened to a helmet chin strap and detects when the user’s head undergoes an impact likely to cause a concussion. Football versions of this device should be on the way to Canada in two weeks, said Battle Sports CEO Chris Circo, and one for hockey is expected to be available in late September or early October. When attached and operating, a green light will be illuminated at the player’s chin. If the light turns red, it’s indicating that the player has been hit hard and should be evaluated before returning to play. “Most leagues and organizations have some protocol that they typically follow (for assessing possible concussions) but (a red light is) saying this kid has had an impact . . . They need to be looked at before they’re allowed to be hit again,” Circo said. The Impact Indicator is programmed to turn red if it senses an impact of 240 HICs (head injury criteria), noting that research shows there’s about a 50 per cent chance of a concussion being suffered at this level of impact. Circo explained that HICs take into consideration gravitational force (G-force) and how long the impact was felt. The 240-HIC threshold, he explained, is essentially a G-force of 75 sustained for five milliseconds. With a personal history of concussions himself, Circo had a motive for moving forward with such a product. Circo, now 42, had three concussions as a child. When he was an adult, he started having seizures. After a battery of tests, it turned out the condition was the result of those childhood concussions. “There are long-term effects on people who sustain concussions,” he said “We have to do something about this.” In recent years, the dangers of concussion and their longer-term effects have gained more attention. Parents have become increasingly concerned about the safety of their children in sports after seeing some high-profile athletes, such as Pittsburgh Penguins star Sidney Crosby, being seriously affected by concussion. Crosby, perhaps hockey’s biggest star, missed half of last season because of concussion, and his status remains uncertain as the NHL season approaches. Because concussions are difficult to detect and young athletes, just like the pros, often want to avoid sitting out, the Impact Indicator is meant to act as an “extra pair of eyes” for coaches, trainers or parents, Circo said. A handful of National Football League players, including Detroit Lions defensive tackle Ndamukong Suh and Denver Broncos receiver Eddie Royal, wear the Impact Indicator, Circo said, even though the device is geared more toward younger athletes. Circo said the Impact Indicator will cost about $200 in Canada and be good for two seasons of play. Ottawa-based Impakt Protective Inc., also has developed a helmet device, called the Shockbox, that detects and records impact to an athlete’s head. It’s a sensor that gets placed inside an athlete’s helmet. When the Shockbox detects a significant amount of impact — a G-force of 60 or more — it sends an alert wirelessly to a smartphone or laptop computer within a range of about 100 metres. It will send an orange signal for hits creating a G-force of between 60 and 90, and red for anything greater than 90. “A number of clinical studies have pointed 90 G or more as being where 65 per cent of concussions occur,” said Impakt Protective CEO Danny Crossman. It comes with software that will prompt the recipient of the alert to perform standardized tests on the player affected to determine whether the athlete has been concussed. It also will maintain history on players’ occasions in which they sustained a significant hit, and whether it resulted in an actual concussion. Crossman said, for the next year or so, the Shockbox will be in trials with unnamed National Hockey League and junior hockey teams. About a year from now, it’s expected to be available as a feature embedded in hockey helmets, and some time after sold separately and as a feature in helmets for other sports. As a stand-alone item, he said it will sell for about $90. <div>Read more: <a href=”http://www.canada.com/news/Technology+lends+hand+concussion+prevention+sports/5274044/story.html#ixzz1du4n1OPt

CINCINNATI, OH (FOX19) – Big hits are a big part of football, but many bring big injuries in the form of concussions. Now there’s a new product that may help protect players and it’s as easy as buckling your chin strap. “We hope to be another tool in the tool box that people can reach for when they want to take that extra step to protect their kids,” said Chris Circo, CEO of Battle Sports Science. Concussions are happening at a faster rate. More than 173,000 happen a year for kids 19-years old and under according to the center for disease control. “My head has vibrated back and forth it’s kind of set me dizzy here and there,” said Nolan Keller, youth football player. Eighth grader Nolan Keller has been playing football for several years. According to Dr. Lori Shutter, a neurologist at U. C. Hospital, Nolan is the type of player most at risk. “Their brains are not completely developed yet,” said Dr. Shutter. And the number of injuries to under-developed brains is growing as emergency room visits are up 60-percent in the last decade. But the bigger concern is that many more go un-detected. “We were able to correlate what was going on in the chin to what is going on in the center of gravity in the head,” said Circo Circo, The CEO of Battle Sports Science thinks his company may have an answer, A chin strap he says can help detect concussion grade hits to the head. “We’ve impacted this device a number of times in the lab,” said Circo The device was tested throughout a 2 1/2 year period at Wayne State University’s Bio-Engineering Lab. When the device is on, a green light is illuminated. The device turns red once hit with enough force to generate a concussion. But Dr. William Knight from the neuro critical care unit at UC Hospital has a concern. “If I have this on my chin, what happens if I get hit in the back of the head, what happens if I get hit on the side of the head,” said Dr. Knight. Despite some of the concerns our doctors have about the device they agreed it’s a step in the right direction. “Parents may want to consider this, consider devices like this,” said Dr. Shutter. And most importantly the chin strap can be an extra pair of eyes for parents, coaches and even the players. If the light goes red are you going to take yourself out of the game? “I would consider it, because I’m thinking about my best interest, as much as I want to stay out there, I know it’s good for my health to come out if I have a concussion,” said Keller. The neurologist FOX!9 talked to for this story had other concerns. We asked Battle Sports Science to address these concerns. There answers are in bold print. 1)      Since the product is on the chin, what happens if the athlete gets hit on the back or side of the head. Will the indicator pick up those hits? Yes, we have placed multiple accelerometers in the device that detects hits from every angle.  2)      Your product’s sensitivity is set conservatively, will the indicator pick up the weaker hits that don’t generate the impact factor but can certainly lead to a concussion? No, we had to select a threshold that was appropriate based on scientific research and studies. If we were to indicate at every impact level, the device would be constantly indicating with few, if any, injuries. Almost all field studies show concussions occurring above the levels we have currently set. Although it happens, the studies show very few impacts below our threshold that result in concussion. We are very clear to everyone involved that the Indicator will not indicate below our threshold and everyone must remain vigilant in terms of watching for the signs of  strong>mild traumatic brain injury (MTBI) at all times.   3)      Also, one neurologist has concerns about the product location on the chin, stating “the forces generated to the lower part of the jaw, may not always be the same forces that the brain is absorbing.” The basis for our product and its functionality is our ability to correlate what happened at the chin back to center of gravity in the head (CG). The doctor is right. That’s why we had to correlate the software to read from the chin back to the force at CG. The correlation work was repeatable and accurate. This is the basis for our products functionaIity. 4)     Does the impact indicator create a false sense of security? If a player receives a big hit and the light remains green, does it set an athlete up for more severe injury because they stay in the game? <strong>It is our belief that a player is at more risk for a severe injury if a head injury is not detected at all. Without the IMPACT INDICATOR, the likelihood of that is much higher. Wouldn’t we choose to have a device to take an extra step in detecting the probability of a serious head injury vs. not? Our IMPACT INDICATOR is calibrated at a conservative level based on research provided by Wayne State University. If the LED light does not flash red, the impact on the field did not register at levels identified through these studies as impacts forceful enough to potentially cause a concussion. Hard hits are going to occur and as we’ve heard from countless coaches and trainers, the biggest issue in youth sports is that kids will not take themselves out. Feedback like this tells us that there’s already a false sense of security issue with kids. The fact that these players are young and have a feeling that they are invincible, is an issue that we believe the IMPACT INDICATOR can be one part of the solution to help coaches and trainers identify a potential head injury and take action. The avoidance of false-positives have been and will continue to be a major focus for us with the IMPACT INDICATOR which is why our company went through the process of working with Wayne State University and put the IMPACT INDICATOR through the most intensive testing in the sports industry. The G-force thresholds set on the IMPACT INDICATOR are a result of these studies.Copyright 2011 FOX19. All Rights Reserved.

Finally a accelerometer to measure force and direction for measuring potential concussions. It’s definitely a start.
