CJSM Blog Journal Club — NMT to prevent ankle sprains in youth soccer and basketball athletes

Our Jr. Assoc Editor Dr Zaremski — already awarded an AMSSM Travelling Fellowship. Is there something bigger in his future?

It’s July, and our fourth edition of 2018 has just published.  One of the headlining pieces of original research we have in this edition is new work from the Sport Injury Prevention Centre in Calgary, Alberta Canada (chaired by Caroline Emery, the well-known researcher and author): Prevention of Ankle Sprain Injuries in Youth Soccer Cland Basketball: Effectiveness of a Neuromuscular Training Program

Our Jr. Assoc. Editor Jason L Zaremski, MD  is today reprising his role as guest author for the CJSM blog journal club  and will take us through his read of the study.  Join in the conversation over this important new, original research by reading the article, the journal club post below, and sharing your thoughts in the ‘reply’ section below this post, or on Twitter at @cjsmonline

Title: Owoeye OBA, Palacios-Derflingher LM, Emery CA. Prevention of Ankle Sprain Injuries in Youth Soccer and Basketball: Effectiveness of a Neuromuscular Training Program and Examining Risk Factors.

Introduction:  The summer Journal Club commentary for the Clinical Journal of Sports Medicine will be an analysis of the new research examining the effects of injury reduction of ankle sprains in soccer and basketball using neuromuscular training (NMT) program in youth athletes. The secondary objective of this study included the evaluation of risk factors for Ankle Sprain Injury (ASI).

Methods:  This study was a secondary data analysis from 3 cohort studies and 2 randomized control trials (RCTs) over the course of 1 season of player in soccer and basketball from 2005-2011. There were a total of 2265 patients aged 11-18 years that play soccer and basketball in Alberta, Canada. Player characteristics (sex, age, weight, height, BMI, sport exposure time, previous ASI, previous lower extremity injury with and without ASI) were divided based upon if a player participated in a NMT program or did not. Frequency between all variables was very similar except for No NMT between females (n=952) and males (n=439) and sport participation without exposure to NMT (soccer = 965, basketball = 426). Average age, weight, height, and BMI were all similar. Exposure time for the NMT group was 72.56 (70.98-74.15) hours versus 62.92 (61.48-64.37) hours for No NMT group.

The Effectiveness of Ankle Taping

To tape or not to tape, that is the question.

And the answer is of interest to a lot of folks out there.

“Residual Mechanical Effectiveness of External Ankle Tape Before and After Competitive Professional Soccer Performance,” published in our January issue, has been our most emailed study so far this year.  On our twitter feed, @csjmonline, I can also tell you that the posts I’ve been making have been getting a lot of traffic.

There is a great deal of interest in this most utilitarian of subjects. It’s original research coming from a group out of Germany:  Best, Mauch, Böhle et al., and currently on the CJSM website it’s FREE!  It’s time to check it out!

All of us in clinical sports medicine can attest to the ubiquity of ankle injuries.  The authors of this study note, for instance, that aside from muscle strains, ankle ‘distortions” are the most frequent injuries seen in professional soccer, accounting for about 20% of all injuries.  They further note that bracing and adhesive taping of the ankle are commonly used to prevent and treat these injuries, though “….the effect of adhesive ankle tape remains inconclusive, in comparison to semirigid orthoses and braces….”

There is considerable debate over the residual effectiveness of taping over the course of a prolonged sporting session.  The issue is of practical significance, as the author’s note that during soccer matches, a disproportionately high number of injuries occur during the last third of each halftime.  To date, there have been few studies that have evaluated the mechanical, protective properties of tape beyond 30 minutes of exercise.

It is in this context, then, that the authors’ developed what amounts to their research hypothesis:  “…during realistic competitive soccer performance reflecting a halftime of 45 minutes–ankle tape might lose most of its assumed initial mechanical effectiveness to reliably prevent ankle distortions.”  They set out to test just that.
