Interesting From ‘Gus’

Here is a TEDx Talk with Kevin Guskiewicz

There are some good moments and some moments that make one scratch their head.  Take a watch (bout 17 minutes) and comment below…

    Good comments, really no talk about CTE, what’s worse, the cou contra cou concussion or the development of CTE and what mechanism is creating CTE. Why only some individuals get it and other don’t. This remains the problem, there is no research that connects repeated cou contra cou concussion to the development of CTE. Just as there none for helmets or any empirical data that shows oral appliances help reduce temporal lobe complex trauma, only anecdotal. Still lots of work to do on what types of trauma are most dangerous, what bio-markers to look for and what to do. Yet alternative research remains far behind for a number of reasons, political, institutional and legal. All we really know, as Dr. Guskiewicz states, concussions are really bad.

    Perhaps GUZ would like to retract his statements regarding damage to children under 15. Mounting evidence is clearly showing long-term effects from m-TBI in children and adolescents see:

    Diffusion Abnormalities in Pediatric Mild Traumatic Brain Injury
    The Journal of Neuroscience, 12 December 2012, 32(50): 17961-17969; doi: 10.1523/JNEUROSCI.3379-12.2012

    Corwin’s Presentation at AMSSM on April 17th, 2013.

    I know GUZ is on Goodell’s payroll and he finances his lifestyle through the NFL but he needs to wake up. On the other hand, he is good enough not to be a hypocrite and has his sons play the game as opposed to the children of union head De Smith and Comm. Goodell (these guys are only interested in you damaging your own kids so they can collect their checks).

    I could go on on as the flaws in this carefully scripted NFL promotional piece (that is what it is – nice job Mr. Aiello) but that would not change anything. GUZ is a go to man for both the NFL and NCAA and will keep making bank by doing there masters bidding by promoting game changers that amount to a little bit of technology and flawed science being spun by a charismatic snake oil salesman practicing outside his field (he is neither a neuroscientist nor a technologist just an ATC like most people reading the board, a clinician) with just enough reality to make it convincing.

    It will be interesting what comes out of his upcoming deposition in the NCAA case. Maybe he and Putukian can explain why they believe college and pro players should be treated with different RTP protocols.

    Sooner or later, GUZ will get thrown under the bus just like Cantu. It is a Faustian deal when you take money from the NFL. Once your soul is sold, it is sold. Enjoy the ride GUZ, the fall is going to be spectacular. Going from a genius to hack in a few short years.

    • Some thoughts on the below cited JAMA article…note the lead author’s name…

      Michael McCrea, PhD; Stephen W. Marshall, PhD; Robert C. Cantu, MD; Christopher Randolph, PhD; William Barr, PhD; James A. Onate, PhD, ATC; James P. Kelly, MD

      Cumulative Effects Associated With Recurrent Concussion in Collegiate Football Players: The NCAA Concussion Study


      In my 2004 Dissertation re Active & Retired Players’ Knowledge of Concussions I raised a significant methodological concern re the contents of the above and frequently cited 2003 JAMA article.

      The narrowness of the operational definition of a concussion was challenged by ths clinician.

      In the article Concussion was defined as:

      an injury resulting from a blow to the head

      that caused an alteration in mental status and 1 or more of the following symptoms: headache, nausea, vomiting, dizziness/balance problems, fatigue, difficulty sleeping, drowsiness, sensitivity to light or noise, blurred vision, memory difficulty, and difficulty concentrating.


      My 2004 Dissertation excerpt follows:

      Guskiewicz et al.’s (2003) recent NCAA study of 2905 college level football players

      found there was a relationship between acknowledged past concussions and the increased probability of a player sustaining another concussion.

      These findings also suggested that players who reported a history of three or more concussions were 3 times more likely to experience another concussion when compared to players who did not report a concussion history.

      The authors also indicated that an analysis of the data “suggested that as few as one previous concussion may present a cumulative effect” (p.2553). They also indicated that the neurological recovery time from a concussion was prolonged for athletes who sustained more than one concussion when compared to athletes who did not report experiencing an earlier concussion.

      It should be pointed out that the above study had a significant methodological limitation due to the narrowness of the operational definition of concussion. The construct was defined “as an injury resulting from a blow to the head …” (p.2550).

      Thus this definition did not include the notion of the whiplash effect and probably led to an under-reporting of the numbers of concussions. The exclusion of the whiplash effect may also misinform the reader pertaining to the pathophysiology of a concussion (p. 41, Brady, 2004).


      Another obvious and significant limitation of the study was the extremely small number of the concussion symptoms utilized.

      Thus it is reasonable to assume that these gross and significant omissions within the concussion definition assuredly led to both:

      1- an under-reporting of the numbers of concussions; and

      2- an under-reporting of the probability rate of experiencing another concussion.

    ALL football players should be required to be examined by an Upper Cervical Specific Doctor of Chiropractic PRIOR to each season to permit safer contact. If the head and neck are in proper stable alignment there will be much less of a chance of sustaining serious injury.
    I am blessed to see it everyday in my office where we find the injury and fix it in basically all concussion cases.
    Furthermore, when it is fixed properly, they do not have second or third concussions. Especially if it is maintained properly over time and monitored, we have yet to see a future concussion take place.
    The athletes best equipment is in their body rather than on their body. Helmets and mouthpieces can reduce some of the forces but it is the upper neck alignment it mis-alignment that is the most important determining factor when it comes to concussions.

    Dr. Guskiewicz if you read this, i hope you expand and/or create another study looking at suicide rates and soccer players. The force at which player begin heading the ball-with no protection- is amazing, game after game, practice after practice. I raised 2 elite female athletes who both earned full rides to D-1 schools to play soccer. There’s data to be collected from this sports population that began hitting & heading balls unprotected FAR earlier than football players do. Young football players usually start their careers in Pop Warner-like leagues which prohibit full tackling. Soccer is a huge sport here in some pockets of the country thanks to the Women’s National Team. Only recently have they come up with a head gear that absorbs some impact little ones receive when they jump up to head a ball. There’s a sizable population, now in their 20s & 30s, who are no longer playing-or are playing rec ball-that I’m sure have data for your team to collect.
    Good work & it’s about time we start showing the underbelly of glory.

      Suggest you:

      1- Google lifeafterthegame soccer blog.

      Lauren Long and Samnatha Sanderson are former soccer players whose careers ended prematurely due to experiencing the adverse effects of multiple concussions…some reportedly soccer related and some nonsoccer.

      Their blog discusses there personal experiences with the lingering adverse effects of suffering numerous
      brain injuries.

      2- Further reflect upon:

      a) Joe Blogg’s above comments

      b) My above comment re a 2003 study. There is a growing concern that concussions / brain injuries are being under-reported.


      Finally, there is existing research that reports comparable concussion rates for football, hockey and soccer.
