National Athletic Trainers' Association Position Statement: Prevention of Anterior Cruciate Ligament Injury

National Athletic Trainers' Association Position Statement: Prevention of Anterior Cruciate Ligament Injury

Padua DA, DiStefano LJ, Hewett TE, Garrett WE, Marshall SW, Golden GM, Shultz SJ, Sigward SM. J Athl Train. 2018 Jan 9. doi: 10.4085/1062-6050-99-16. [Epub ahead of print]

The National Athletic Trainers’ Association has released a new position statement on the prevention of anterior cruciate ligament injury. The document focuses on multicomponent injury-prevention training programs. The recommendations fall under 5 headings: 1) effects of injury-prevention training programs on injury reduction and performance enhancement, 2) exercise selection and training intensity, 3) training volume (frequency and duration), 4) implementation of multicomponent injury-prevention training programs (program adoption and maintenance), and 5) targeting individuals for injury-prevention training programs. The document also includes a nice summary of the literature.

Note: The Journal of Athletic Training has a new twitter account: @JAT_NATA. They plan to share their latest publications and roll out new initiatives to engage scholars/clinicians.

FMS is Not a Crystal Ball

The Functional Movement Screen as a predictor of injury in National Collegiate Athletic Association Division II athletes.

Dorrel B, Long T, Shaffer S, and Myer GD. J Athl Training. 2017. [Epub Ahead of Print].

Take Home Message: The Functional Movement Screen is slightly better than flipping a coin at predicating who will get an athletic injury.

Businessman Consulting Glowing Crystal Ball The Functional Movement Screen (FMS) is a tool which helps clinicians identify body asymmetries and identify inefficient movement patterns. While FMS may differentiate injured and uninjured people some investigators have challenged the notion that FMS could identify athletes at risk for injury. Therefore, Dorrel and colleagues completed a prospective study to examine the prognostic accuracy of FMS to predict injury among NCAA Division II athletes.

Concussion Prognosis May Be In Your Saliva

Association of salivary microRNA changes with prolonged concussion symptoms

Johnson JJ, Loeffert AC, Stokes J, Olympia RP, Bramley H, Hicks SD. 2017. Am J JAMA Pediatr: ahead of print.

Take Home Message: Measuring levels of microRNAs in saliva may help predict who will have prolonged concussion symptoms.

Clinical tests that enable medical professionals to predict the length of concussion recovery would be helpful to curate rehabilitation programs and to decrease the athlete’s anxiety of when they can return to daily activities. Currently, no such tool exists. Epigenetic molecules known as microRNAs change after a traumatic brain injury; however, no one has examined the predictive ability for microRNA to detect prolonged concussion recovery. Therefore, the authors evaluated 52 people between ages of 7 and 21 years to determine the efficacy of salivary microRNAs to identify people with a concussion who are at risk for prolonged symptoms.

Neuromuscular Training Programs Reduce the Risk of Injury in Youth Athletes

Dose-response relationship of neuromuscular training for injury prevention in youth athletes: A meta-analysis.

Steib S, Rahlf AL, Pfeifer K, and Zech A. Front Physiolo. (8) 2017.

Take Home Message: A 10-15-minute neuromuscular training program deployed at least 2-3 sessions per week could offer more than a 45% reduction in risk of lower extremity injury.
Youth athletes are at greater risk of injury than nonathletes. Neuromuscular training programs effectively decrease sports-related injury rates, yet dose-response guidelines are unavailable. Therefore, Steib and colleagues completed a systematic review and meta-analysis to identify the optimal dose of neuromuscular training to prevent lower extremity injuries in youth sports.

Orthoses Clinically Reduce Lower Extremity Injuries

Effectiveness of foot orthoses for the prevention of lower limb overuse injuries in naval recruits: a randomised controlled trial

Bonnano DR, Murley GS, Munteanu SE, Landorf KB, & Menz HB. Br J Sports Med. 2017; Online Ahead of Print December 9, 2017.  

Take Home Message: Prefabricated orthoses may reduce the risk of chronic lower extremity injury during a naval recruit training program.
Foot structure and function play a large role in overuse lower extremity injuries.  As clinicians, it may be valuable to use exercises or external devices – such as orthotics – to prevent these injuries.  Hence, these authors conducted a double-blind randomized controlled clinical trial to compare the incidence of chronic lower extremity injuries between approximately 150 naval recruits who received prefabricated orthotics to about 150 who had flat insoles during an 11-weeks training period.

Even Elite Athletes Suffer the Backfire of Sport Specialization

The effects of playing multiple high school sports on national basketball association players’ propensity for injury and athletic performance

Rugg C, Kadoor A, Feeley BT, Pandya NK. 2017. Am J Sports Med: ahead of print.

Take Home Message: Though most of the NBA first round draft picks were single-sport athletes in high school they were also more likely to suffer injuries and participate in less games compared with their multi-sport peers.
Young athletes who specialize in one sport at an early age are at a high risk of burnout and injury. Many parents and athletes believe sport specialization is necessary to achieve athletic success later in life (college/university scholarship, professional status); however, there is little evidence to support this belief. Therefore, the authors identified the 237 National Basketball Association (NBA) first-round draft picks from 2008 to 2015 (who played at least one NBA game) to determine the frequency of athletes who played a single sport or multiple sports in high school and compare injury rate and length of careers.
