  •  That sounds fantastic (8+ / 0-)

    It also sounds like the test needs some refinement.  Possibly testing player's reaction times at the beginning of each season, and determining a significant prolongation time as a ratio would be a more sensitive test.  Players will start with different reaction times, and individual player's slowing after a hit might be a more sensitive test.  Averaging three tries might also refine the technique.

    I also wonder if this could be used in other areas of neurological illness, such as early dementia or Parkinson's diagnosis.  Thanks for bringing this interesting news.

    •  Thing is Teens & 20 Somethings are Remarkable (4+ / 0-)

      for learning manual tasks on few numbers of tries. As a recreational instrumental music teacher of that age range, the observation that the athletes often did even better on a 2nd try is very familiar.

      By mid to late 20's that doesn't happen any more. From teens to 20's because of the superior ability to learn manual tasks it might be that almost any decline in speed might indicate a problem, though simple fatigue would be something to account for.

      •  Perhaps - more study is definitely indicated (3+ / 0-)

        Of course, if fatigue is also impairing reaction time, that too might be a good reason all in itself to have an athlete take a break - they're more likely to get injured.

        Part of the problem is that the players themselves have a huge incentive to go back out on the field - and coaches have one to send them as well - regardless of how they may be feeling. Nobody wants to lose a big game (or even a small one) and nobody want's to get a rep as being injury prone or 'unmotivated'. Competition is all about pushing limits.

        That this test is simple, easy to interpret, and hopefully objective will make the decision to go or not go back into a game a lot easier to make.
