Building a better test concussion ;

When athletes get your bell rung in the field or court, there is often tension between his I desire to keep playing and responsibility of a coach to prevent further harm to themselves. The problem with concussion in the standard field protocols, including the most recently used by the National Football League, is that several of its components are subjective and prone to human error.

Researchers at San Diego State University have developed a cheap, ultraportable balance table called BTrackS that provides rapid and objective information ultimately the interruption of an athlete after suspicion of a concussion. The results of the first screening study concussion team have shown that it is twice as effective as the test most widely used to balance the commotion across the country.

balance problems is one of the main symptoms of a recent concussion. Most governing bodies in sport recommends three test components in a concussion protocol: physical symptoms, cognitive function and balance. For the part of balance, most sports organizations use what is known as the test BESS (Balance Error Scoring System). Using this system, the coaches ask athletes to be in a variety of positions while remaining as still as possible. Coaches begin to count the number of errors, such as out of position or removing your hands from the hips, and determine whether the person is likely to shock or not.

Research suggests that the BESS test accurately captures a concussion about 30 percent of the time, according to SDSU kinesiologist Dann Goble, inventor of BTrackS and first author of the study.

“The problem with the BESS system is that it is very unreliable,” Goble said. “We often get different results from the score of different people watching the same athlete go through the protocol.”

You can measure the balance objectively using force plates that track precisely how much a person is balanced, but most of these devices are either very large, very expensive, or both, making them unlikely to gain traction in sports. Goble has adapted this technology on a balance board about the size of a suitcase that connects to a computer or laptop, all for less than $ 1,000. The project was initially supported by Zahn SDSU Innovation Platform implementation.

To test whether the technology could accurately detect concussions in a real environment, Goble and colleagues took measurements of balance baseline from more than 500 NCAA Division I student-athletes at SDSU compete in a variety of sports, such as soccer, rugby, lacrosse, soccer, basketball and water polo. Then followed the athletes throughout the season.

If a player suffered a head injury, coaches measure their balance using BTrackS and the new score is compared to the initial score. If the new domain score was on average higher than 5 centimeters baseline, then the system predicts an interruption indicative Goble balance of concussion. Athletes also received follow-up care from a doctor who can diagnose reliably whether or not they were a concussion.

Of the 25 athletes, determined by a medical team to have bruises received, BTrackS detected 16 of them, giving the technology Goble a success rate of 64 percent, more than double that of the BESS test. The results were published this week in the International Journal of Sports Physical Therapy .

“We would like as many sports organizations such as the possible change to the best technology,” Goble said. “This device must be everywhere.”
