The new 2013 sale louboutins shoes guidelines call for any athlete suspected of having a concussion to be immediately removed from play and not returned until after an assessment by a licensed health care professional trained in concussion. The recommendations stress a gradual return to the game -- and only after all symptoms are gone.

"If in doubt, sit it out," said Dr. Christopher Giza, a children's neurologist at the University of California in Los Angeles and one of the lead authors of the guidelines that were published Monday in the online issue of the journal Neurology. "There is no set timeline for safe return to play."

The old guidelines, in use since 1997, grade the severity of christin louboutins shoes concussion on a scale of I to III. Most experts classify a mild concussion when the athlete is confused but has full memory of the event as Grade I. Typically, the athlete is told to sit on the sidelines for a few minutes before returning to play.

Grade III concussions are characterized by loss of consciousness and memory loss for a period of time surrounding the events. Athletes diagnosed with a Grade II or III concussion are usually asked to stop play and practice for at least a week and return after being cleared by a physician.

The problem with the old guidelines, Giza said, is that they find sale christian louboutin, shoes outlet, louboutins shoes cheap emphasize prevention and aren't very good at predicting how long someone might experience symptoms such as headaches, dizziness and memory deficits, which can plague someone after the initial injury.

"Sometimes an athlete who is knocked unconscious will recover quickly, while an athlete who gets what seems like a small bump on the head struggles for weeks," he said.

The new guidelines were developed by reviewing all available evidence published from 1955 through 2012. Neurologists, athletic trainers, rehabilitation medicine specialists, sports medicine experts, epidemiologists and a host of other specialty experts contributed to the final recommendations.
