The 2019 AMSSM Position Statement on Concussion — a Podcast with Dr. Kim Harmon

How to manage concussion in sport in 2019: The AMSSM Position Statement, and the new CJSM podcast

As one of our partner societies, the American Medical Society for Sports Medicine (AMSSM) contributes significantly and regularly to the global sports medicine discussion.  When the AMSSM authors a position statement, it’s a document that should be read by the active sports medicine clinician

Prof. Kim Harmon, past-president of the AMSSM

Hence, the publication of the AMSSM Position Statement on Concussion in Sport is news we want to make sure you all know about.  And if you haven’t had the chance to read it yet, you can now take the opportunity to hear about it from the publication’s lead author, Dr. Kimberly Harmon of the University of Washington.

For the new statement, Dr. Harmon notes that she and a panel of expert authors adopted a very specific focus: what does the practicing clinician need to be current when diagnosing and managing a concussion in 2019. This is a document for the sideline, the training room, the clinic.  A document for ‘now.’

It is evidence-based, but also ready to assist clinicians in the areas of concussion where evidence is currently limited.  That is, the statement makes suggestions for needed future research directions, but also reports current best practices informed by consensus or expert opinion.

After reading it, I found myself immediately referencing the statement when conversing with patients and families, whose questions might range from whether their child should take fish oil after their concussion (no, unless your child is a rat, as Dr Harmon may say….) to whether they are ready to drive (well, that depends….).

If you want especially to hear interviews we’ve had with authors of previous AMSSM Position Statements, check out as well our podcasts with Dr. Jonathan Drezner (cardiovascular screening) and this one with Dr. Irfan Asif  (best practices for a sports medicine fellowship).

It’s a New Year — CSJM Blog Journal Club 2019 Starts Now

Japan (and its iconic Mt. Fuji) will be one of the places on the globe that will be enjoying an exciting 2019 in the world of sport.

We here at CJSM hope all of our readers have enjoyed a festive and relaxing holiday season.  I am sure for most of us reading this post, ‘things’ have picked back up, because the global sports world never sleeps.  From Australian Open tennis to the NFL playoffs to the English Premiership, and beyond, the sports (and sports medicine) scenes have been ushered in with a bang.

2019 promises to be an exciting year in sports all over, but perhaps in no place quite like Japan, as it hosts the Rugby World Cup at year’s end and busily prepares for the 2020 Summer Olympic Games in Tokyo.  I just spent my holidays there and fell in love with the country.  I am looking forward to posting more about the upcoming global events Japan is hosting this year and next.

CJSM has entered the new year with a bang as well, as we begin our 29th year with an issue that is full of interesting offerings.

Among the pieces of original research we have just published in this January 2019 issue is this one: Head Impact Exposure in Youth Soccer and Variation by Age and Sex. This piece has already received a good deal of attention. The accompanying editorial arguing (relatively speaking) against a ban on heading in youth soccer has realized a comparable buzz.

We thought this would be a particularly good study to ‘de-construct’ in the Journal Club, and so we contacted our regular correspondent Jason Zaremski MD to pen one of his ever popular, recurring posts.  Thanks Dr. Zaremski, as always.

Introduction:  

The newest edition of the Journal Club commentary for the Clinical Journal of Sports Medicine (CJSM) will be a review of an original research manuscript highlighting a very interesting topic, heading in “soccer” (referred to as “football” outside the United States) and its effects on our youth athletes. As the authors note, there are more than ¼ of a billion soccer players worldwide. In the USA, there are approximately 24 million soccer players and more than 37% are youth players. In the past few years there have been growing concerns about heading in youth soccer and possible associations with concussions and sub-concussive head impact exposures (HIE). Due to these concerns, individuals and some leagues (from local levels to national) have suggested a ban of heading to limit body contact and potential HIE. However, prior research has suggested that the actual number of youth players heading a soccer ball as well as intentional impacts with head to ball are low and heading restrictions may not be indicated. (Comstock et al JAMA Ped 2015, Lynall et al MSSE 2016, Press and Rowson CJSM 2016). Therefore, in order to obtain more objective data, the authors of this study wanted to objectively measure HIE in males and females at the youth level.

Purpose/Specific Aim(s):

The purpose of this study was to measure HIE using adhesive-mounted accelerometers during 1 month of soccer. Read more of this post

Concussions: The “Injury of 2018”

Concussions remain a dominant subject in the sport medicine literature and media at large — Photo: PET Scan Brain, Wikimedia

As 2018 winds down, the Clinical Journal of Sport Medicine, like so many of its sister media, finds itself in a reflective mood.

Time magazine, for instance, has just named its “Person of the Year”: a group of journalists the magazine notes has been ‘targeted’ for the work they do pursuing the truth.  Time calls them The Guardians. It is an interesting selection:  a media outlet honoring other professionals in its own line of work.

I thought it time that CJSM do its own version of “Person of the Year,” but with a sport medicine twist — Injury of the Year.

I’m naming “Concussion” the Injury of the Year.  In 2019, I’ll have my ‘act together’ and put out a Twitter poll in late November for reader contributions; but in 2018, I’ll have to play judge and jury, given that it’s nearly mid-December. Thanks for indulging me!

Like LeBron James of the NBA, who could probably be named MVP in any year he has played in the league, concussion is a sports injury which could probably earn this distinction in any year over the last decade or more.

In truth, 2018 was a red banner year for the injury, so to speak.  As an example, nearly our entire March 2018 issue was devoted to original research on various aspects of the subject, including a systematic review on the long-term consequences of traumatic brain injury in professional football players.  Continuing this line of reasoning, I would draw your attention to another noteworthy systematic review just published in our last issue of 2018 (November).   This one looks at the utility of blood biomarkers in the assessment of sports-related concussions (spoiler alert:  we have a long way to go in developing these for ‘prime time’).

The dominant theme of our 2018 podcasts was, again, concussion.  Read more of this post

CJSM podcast with Chris Nowinski: What FIFA might consider doing differently in 2022

It was a whirlwind of a month that just ended:  World Cup 2018 has been rightfully celebrated as a wonderfully exciting display of sport.  Media outlets around the globe are reflecting on the highs and lows of the tournament. 

One of my favorite comments was a tweet conversation involving former English professional footballer Gary Lineker:  “Back to politics now, eh?/ What a depressing thought.’ 

Politics. Ugh.

Twitter was also the media where I read some of the most insightful commentary on the various concussion controversies that occurred this tournament, and Chris Nowisnki, Ph.D. was among the most prolific and penetrating in his analyses of the injuries to Matuidi and others.

Dr. Chris Nowinski of the Concussion Legacy Foundation

Dr. Nowinski will be a familiar figure to anyone involved in the management of sport-related concussions. Dr. Nowinski is the CEO and co-founder of the Concussion Legacy Foundation and a co-founder of the Boston University CTE center. He has been a guest on the CJSM podcast previously.

He was the perfect analyst to review what sport still gets wrong about concussions in 2018, and to review the directions where we all might consider going as we turn toward FIFA 2022 in Qatar.

Go to our podcast link on the CJSM website or on iTunes — listen to what Dr. Nowinski has to say, and then let us know what you think.
