(For all Inside Slant posts nike

the moment, and everything that followed, down to its finest detail. As a
Detroit Lions defensive end in 2010, Jackson was chasing Dallas Cowboys
quarterback Jon Kitna. When Kitna sidestepped him, Jackson collided with
teammate Kyle Vanden Bosch, spun in a helicopter motion and felt himself go limp
for a few seconds."When I got to the sideline," Jackson said, "I knew I was
concussed. But I wasn't disoriented. It wasn't like I didn't know where I was. I
just had a headache and I could tell. But at that time, the test was pretty easy
if you don't have a significant concussion. It still is. They asked me what day
it was, approximately what time it was, what quarter we were in. They wanted me
to say the months backwards and a few other things. I got those right. I didn't
look disoriented, so they really didn't have any choice but to let me go back in
the game."[+] EnlargeTimothy T. LudwigUSA TODAY Sports"Unless you're
really screwed up," Lawrence Jackson said, "anybody can pass a sideline
[concussion] test."Jackson returned, sacked Kitna on his third play back and
went on to one of his better games in a Lions uniform. Taking care to avoid
further contact with his head, and playing through what he felt was an
"out-of-body experience," he totaled 1.5 sacks in 32 snaps. He reported his
symptoms the following day and was held out of the Lions' next game, a sequence
of events that Jackson recalled via phone this week amid continuing discussion
about the condition of New England Patriots receiver Julian Edelman in Super
Bowl XLIX.Edelman, as we noted at the time, displayed concussion symptoms based
on the NFL's current protocol after a hit from Seattle Seahawks safety Kam
Chancellor. Edelman did not leave the game -- although he was administered a
sideline concussion assessment between possessions chaussures nike air
max , according to The Associated Press -- and he ultimately scored
the winning touchdown. Edelman has refused to discuss the hit, most recently
during an interview with the New York Times last weekend, citing the Patriots'
rules about discussing injuries publicly.To Jackson, speaking not from a medical
sense but from personal experience, the episode is fairly simple. Edelman,
Jackson guesses, endured what players refer to as "getting your bell rung," but
what is in reality a sub-concussive injury. It leaves players altered and
vulnerable but still aware enough to pass a typical sideline test if they don't
disclose their condition verbally.Of course, we don't know the details of
Edelman's circumstance and might never find out. But the issue, along with
Jackson's story, illuminates what is currently an unavoidable gap in the NFL's
concussion-related efforts. Whether or not it happened with Edelman, players
still can and do beat the sideline test despite the best efforts of medical
science and a protocol the league enhanced in 2013."Unless you're really screwed
up," Jackson said, "anybody can pass a sideline test."This mindset doesn't come
as a surprise to the NFL's medical community. I spoke this week with Dr. Javier
Cardenas, the medical director of the Barrow Concussion and Brain Injury Center
in Phoenix. Cardenas also serves on the NFL's head, neck and spine committee and
was one of the league's two independent sideline neurologists at the Super Bowl.
Although he couldn't speak specifically about Edelman's case -- other than to
say: "If there is a question about evaluations being made, I can assure you they
were made" -- he readily acknowledged the shortcomings of the current sideline
protocol.When I told him Jackson's theory about beating the test, Cardenas said:
"It's true. It's true. The test is as good as we have today. We do our best. The
truth of the matter is, this is a two-way street. Of course, not always are the
athletes aware of their injuries. Some of them don't recognize they have a
concussion nike

they have a responsibility to their team, to themselves, to their loved ones of
declaring that they don't feel right. The tests are only as sensitive as they
can be. They're imperfect."Cardenas estimated that only 10 percent of
concussions result in an easily diagnosed loss of consciousness or obvious
disorientation. The rest lead to varying stages of what is termed "altered
consciousness," the type Jackson said he suffered in Dallas.The NFL's enhanced
protocol put an independent neurologist such as Cardenas on each sideline; they
stand at catty-corner 25-yard lines to maximize coverage of the field. An
independent athletic trainer is stationed in the press box, and the three scan
the field throughout the game for possible concussions, using a video assembly
on the sideline to review hits when necessary.[+] EnlargeKen BlazeUSA
TODAY SportsDoctors hope to one day be able to test for concussions
chemically through saliva or blood.The NFL has distributed guidelines for the
initial sideline test of a player displaying symptoms, viewable here. Cardenas
said he first asks a player to describe "what happened," knowing that any gap in
the story is usually a sign of a concussion. Players must recite facts such as
the opponent, what quarter the game is, who scored last, who won the previous
week and then repeat a series of numbers and words. If the player's responses
are deemed unsatisfactory, he is taken to the locker room for a full
assessment.But it's the initial test that a slightly altered player, or one
whose symptoms could be delayed, can reasonably pass. To combat this
shortcoming, Cardenas' research group is among those searching for a more
objective assessment tool that would identify the release of certain chemicals
from the brain associated with concussions.The "holy grail," Cardenas said, is a
custom mouth guard that would change colors when it detects the
concussion-related chemicals in saliva. Research to that end is underway, but
reliable tests are 锘? 20.
