Vick's concussion: The sideline assessment

By now, you’ve probably seen the hit that forced Eagles quarterback Michael Vick from Sunday’s game with a concussion—his second in as many seasons.

This afternoon, typically reticent coach Andy Reid revealed that Vick’s was a “pretty significant” concussion, so in hindsight the decision to hold him out of the contest was likely an easy one. But the quarterback was evaluated on the sideline before the leaving for the locker room. What can doctors determine during that brief period?

We asked Robert Franks, D.O., who specializes in concussion management at the Rothman Institute and contributes regularly to this blog. Dr. Franks says the first assessment happens literally on the field. ‘You have to determine whether they’re stable enough to come off the field,” he says. “Is there an associated neck injury, or do you suspect something catastrophic that needs to be transported immediately?”

Once the doctor clears that hurdle, sideline assessment can begin. A cranial nerve exam, muscle strength and reflexes are all tested before beginning the SCAT2 (Standardized Concussion Assessment Tool) test.

“That’s what most athletes are put through,” Dr. Franks says. “The NFL has its own sideline examination that uses the SCAT2 as a template, but it’s a little more in depth.”

The SCAT2 looks at some basic parameters typically assessed in an office. For example:

  • Balance. A BESS (Balance Error Scoring System) test walks the athlete through a few different stances—standing on one leg, one foot in front of the other, then both feet together. It’s about a 20-second test conducted on a 30-point scale, with points deducted for each deficit in balance.
  • Symptom Checklist. “What symptoms do they have, and how bad are they?” asks Dr. Franks. Based on a series of simple questions—do you have a headache? Do you feel foggy or drowsy?—as well as assessing irritability and emotion, the doctor can assess the level of involvement.
  • Maddocks Score. This part of the test focuses on questions that should be answered rather easily. Where are we today? Who did you play last week? Who scored the last touchdown?
  • Standardized Assessment of Concussion (SAC) Test. This consists of general orientation questions—what time is it, what month is it?—followed by evaluating immediate memory. “I’ll give them a list of words, like ‘elbow, apple, carpet, saddle, bubble’ and they’ll have to repeat the words back to me,” says Dr. Franks. “Then I give the player a string of digits, and have him repeat them to me backwards. So if I give them ‘4-9-3’ they need to give me ‘3-9-4’.”  

The coordination examination—the widely-known ‘follow my finger’ test—is followed by a return to the SAC test. “I have them give me those five words again—elbow, apple, carpet, saddle, bubble,” he says.

Through that assessment—which Dr. Franks says can be performed in 10-15 minutes—you can gain a feeling of the functionality of the athlete. “We’ll give them a cumulative score, based on everything they just did on the sideline,” he says. “You’re scoring them on a basis of 0-100.”

While experts are hard at work to establish one, right now there’s no magic number for what constitutes a ‘good’ or ‘bad’ score. “The closer to 100 you score, the better off you are,” says Dr. Franks. “Ideally, you want to see them get 30 out of 30 on the balance scale, 5 out of 5 for delayed recall on the SAC questions and so on.”
