In a follow-up, and what I believe to be the same presentation that Elanor Profetto’s video is from a very strong and wonderful woman, Sylvia Mackey, “Mrs. 88″ gives a talk about brain injury. She also has intimate and troubling experience with what brain injury/disease can do as she took care of the great John Mackey in is twilight.
Keep on learning and listening!
Been on a video binge lately… Look for more, but for today please take a listen to Eleanor Perfetto. There are some points that some may (including me) not agree with entirely, but she has earned the right to be heard! Not only is she a pharmaceutical epidemiologist, she is the widow of Ralph Wenzel.
Look for more video tomorrow…
I am finding it hard to find time to post, obviously, but I will get back to this as soon as I can. For the time being here is a decent video I have had forwarded to me that can be a good example of concussion or mTBI…
I would love to see discussion on this, below!
I occasionally look for videos for education purposes. Today, I found a really good one, except for the “minor concussion” note early on…
More to come today…
I found a very interesting email about research being done at the University of Oregon. It was so well written I thought I would just place it on the blog…
In what may be the first study of its kind, the University of Oregon’s Motion Analysis Laboratory released a fascinating and chilling new video that illustrates the dramatic effect a concussion can have on high school athletes’ ability to control balance while walking.
Using computer generated images from reflective markers worn by the subjects, the video shows the gaits of two high school students – one a healthy subject and the other a victim of a concussion from a helmet-to-helmet collision in football practice two days prior – to emphasize the poor control and balance of the concussed athlete.
The full study included 40 high school athletes – 20 who were diagnosed with a concussion from sports including football, soccer, volleyball and wrestling, and 20 similar healthy athletes – who were tested over a two-month period. The results showed that the concussed athletes had trouble maintaining balance and walking speed while also responding to auditory cues as long as two months following the concussion.
Research on concussion recovery time, like what is being done at the University of Oregon, may help improve safety and better pinpoint when it is safe for to return to field or court.
First I want to lead this off by saying it is not a “crisis” just for the NFL, or football, this is an issue for everyone. Once again this provides me the opportunity to say; the injury of concussion is not the problem/elephant in the room, rather it is the mismanagement of those injuries that have created this problems we are facing.
This video is from YouTube and I was tipped off by Dave Pear to its existence.
It is 11 minutes in length but there are some good sound bites in it. If you can wade your way through the minutia you will see that the repeating issue is what I have stated above. Basically doing nothing to fix the real problem.
I have posted many a video about concussions here on the blog but this one (thanks to Tommy Dean) may be the best for its pure simplicity and message about management;
People need to understand that concussions don’t have to involve a hit to the head. I have seen throngs of people on Twitter and other places not grasping this. Perhaps none more so in the product development sector; those very intuitive people with good ideas that think protecting the head will reduce concussions. Be it a helmet addition, or better helmet, or those that want to remove helmets from the game, what they fail to grasp is that linear hits to the head with linear forces alone do not constitute the majority of concussion sequale. The concussion comes as a result of a constellation of factors; the biggest of which is the acceleration/deceleration of the head, followed closely by the shearing (due to angular and rotational forces) of the head. If you notice most mechanisms of injury one would easily note that knocks to the head with limited movement of the head itself, are not the vast majority of concussions seen. The hits a person takes in sports and LIFE that are unanticipated and have multiple vectors is where we get a lot of concussions from.
For a better visual, if I were to say to you I am going to punch you in the face from the right side, and you had a chance to brace for it, there is a good chance you could absorb that blow with little to no problems. However if I were to not say a word and walk up and hit you in the same spot with the same force, the chances you will be “hurt” are much greater. When you anticipated the hit you would have braced and made the force almost strictly linear, with little rotation due to your neck muscles… Where as, the sucker punch would move your head sideways and back; quickly accelerating your head then suddenly it would be decelerated by the spine range of motion limits.
I hope this has provided some positive learning for everyone…
What I believe was at the same conference as the previous video by Dr. Jeffrey Kutcher; former coach Lloyd Carr speaks about concussions;
Coach Carr was the head football coach at the University of Michigan from 1995 – 2007, it is worth listening to this perspective. Although coaches can be to blame for much of the “complaining” when it comes to the necessary changes in any sport as it relates to concussion, their input is very worthy.
We can sit in our offices and come up with “dream” ideas, but these are the men/women that must implement all the “bright” ideas. There is something to be said for those that have “been-there-done-that”, so as long as it is both constructive and respectful. I believe that Coach Carr did a good job of this.
A quick side note; this was in 2011 and he spoke of leading with the head, now the NCAA and NFL will possibly eject players for leading with the crown of the helmet (a very hot debate, and will be once the season begins).
The University of Pittsburgh Medical Center and the University of Pittsburgh did something that has not been done up to this point; an intensive study on youth football. Using geography as its selector the prestigious group looked into Pop Warner football and concussion rates. The sample size is impressive, over 11,000 athletic exposures over an entire season of play (2011).
However, instead of heralding the work more questions have been raised about the conclusions drawn by lead researcher Micky Collins, PhD. I don’t want to “lead the witness” before you had the chance to hear yourself, watch Dr. Collins below;
Interestingly enough Dr. Collins’ points regarding the depth and breadth of this investigation are spot on, it was both needed and welcome. It is good to have a starting point and something to say “this is where we came from” at all levels of sport – with regards to concussions. After that, I personally Continue reading
For a long time the “father” of CTE, the first pathologist to find/identify the disease in an American football player, Bennet Omalu has been relatively quiet; going about his normal business and continuing his work with CTE. Last week he was highlighted on the ESPN Outside the Lines/PBS Frontline story about the Junior Seau death aftermath.
Even more recently Dr. Omalu was invited to speak at the 2013 Football Veterans Conference – a sport specific event put on by Dave Pear and his blog;
Well, we just wrapped up our 2013 Football Vets’ Conference in Las Vegas at the South Point Resort and it was our best yet! In two packed days, we covered everything retired football players need and want to know, from concussion lawsuits to CTE to visual rights and everything in between. Our sessions were packed and no one wanted to miss a single discussion. And thanks to the amazing Jennifer Thibeaux, all of our discussions from Friday are already processed and uploaded so you won’t have to miss a minute of it either!
Thanks to Dave we can bring you the entire talk by Omalu – although over an hour its worth your time.
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…
This is a re-post, sort of, of a video created by Bryson Reynolds a neuroscience graduate student. His area of study is concussions and mTBI. He shortened the original video for easier consumption, it still holds the essence of what makes it a good too for us to use; stark and striking objective mechanisms of injuries, across all sports.
It is barely over a minute in time, again this is a great teaching tool for those trying to understand the mechanisms of concussion. If I counted correct only 4 of the clips show head-to-head contact. THIS IS EXTREMELY NOTEWORTHY, as concussions occur without direct blows to the head. Also note the concussions (presumed by the filmmaker due to descriptions of the original videos) that occur due to contact with the ground or ball. Perhaps the most disturbing videos are the last two, youth sports.
Neurologists at Mayo Clinic in Arizona have taken a promising step toward identifying a test that helps support the diagnosis of concussion. Their research has shown that autonomic reflex testing, which measures involuntary changes in heart rate and blood pressure, consistently appear to demonstrate significant changes in those with concussion.
Appearing on their website, the information researchers are delving into is a new angle on concussions. It is widely known that traumatic brain injured (TBI) patients have autonomic system (ANS) deficits/abnormalities. However the group from Arizona thought an investigation into concussed patients was worth the effort. Low and behold their findings are a promising first step in possible assessment and management of the concussion.
One interesting note, was this notion on dizziness;
“Contrary to popular belief, the symptoms of ‘dizziness’ that patients feel just after a concussion may, in some cases, be symptoms of autonomic system impairment rather than a vestibular or inner ear disturbance,” says Bert Vargas, M.D., a Mayo neurologist.
No one is telling you to take blood pressures with assessment (ergo baselines), yet, but with this information could come not only objective testing but biomarkers associated with ANS changes;
“This study shows a possible electrophysiological biomarker that indicates that a concussion has occurred — we are hopeful that with more research this will be confirmed and that this may also be a biomarker for recovery,” he says.
Here are a couple concussion videos that I have found recently…
This first one from Mayo Clinic is an AWESOME example of what happens at the lower levels when you try to push through a concussion and keep doing what you were doing;
I was watching this video and looking at good example of how NOT to hit. Most of these hits are from 2010 or before, and you know what, I really feel like we seeing less and less of these hits in the game. Perhaps the rules actually being enforced are making a change?
Stephania Bell of ESPN absolutely knocked this teachable moment on concussions out of the park. I really appreciate her discussing not only the qualifiers/labels on concussions – BTW Eagles just as there is no such thing as a “mild” concussion there is no such thing as a “significant concussion” they are all significant brain injuries – but the recovery time associated with concussions. Thank you for listening Stephania and thank you for this great segment!
FWIW, from my sources around the league the NFLPA may want a specialist on the sideline, but the owners are resistant to this for two primary reasons: 1. cost and 2. unfamiliarity with the players. The second would be more of a player issue rather than an owner issue, however it seems we will not see any owner override his MD’s on the sideline. Again this all boils down to possible conflicts of interest.
USA Football has put together a series of concussion education videos. They can be found on YouTube but here are all five of them;
This video was posted to YouTube and – merely guessing here – it seems it was for an English 2 project. Other than the occasional spelling error and “liberties” taken with the information about players taking their lives it really is a fine piece. So take five and give it a watch, as of last week there was 11 views.
There are many places that provide modules for concussion education. One of the newest entries in this area is the University of Michigan and Michigan NeuroSport. Watch this video and once again see an example from a high school athlete.
Apparently it is video day here at TCB. This video appears to be a class project, it may not be the best quality, and they did not cite all of their sources (ahem), but the information is solid and can be useful for parents/general public.
This video is from Fox Sports and is a quick editorial from Dr. Mark Adickes (@jocktodoc) about the concussion issue, particularly the Dave Duerson case;
Look at #81 at the top of the screen after a hit by a Bronco defender. Not only the hit, but him trying to get back up.
Tony Moeaki Stumbles After Hard Hit
Thanks Coach F. for alerting me to this video.
If anyone knows how I can embed this, previous setting not working, simple paste of embed code in HTML page is resulting in just a link.
Via YouTube. A side note, for some reason the videos are not embedding like they used to. If anyone has a clue as to how to fix that, can you let me know?
For all those that may have missed it here is the video of Stewart Bradley after the hit that he sustained the concussion on…
THIS IS A PERFECT EXAMPLE OF WHAT REFEREES, COACHES, AND OTHERS SHOULD BE LOOKING FOR IN HIGH SCHOOL FOOTBALL…
