High adherence to a neuromuscular injury prevention programme (FIFA 11+) improves functional balance and reduces injury risk in Canadian youth female football players: a cluster randomized trial
Steffen K, Emery CA, Romiti M, Kang Jian, Bizzini M, Dvorak J, Finch CF, and Meeuwisse WH. Br J Sports Med. 2013; [Epub Ahead of print].
Take Home Message: High adherence to a neuromuscular injury prevention program like the FIFA 11+ decreases the risk of injury.
Injury prevention programs typically are multifaceted warm-up programs that focus on neuromuscular recruitment. Although various programs aim to improve performance and decrease injury risk no investigation has shown a link between improved physical performance and the quality and adherence of neuromuscular injury prevention training. Therefore, Steffen and colleagues completed a cluster-randomized trial to assess the influence of player adherence and delivery method of the FIFA 11+ injury prevention program (approximately 20 minutes, 15 exercises) on injury risk among females.

Early decrease of serum biomarkers of type II collagen degradation (Coll2-1) and joint inflammation (Coll2-1 NO2 ) by hyaluronic acid intra-articular injections in patients with knee osteoarthritis: A research study part of the Biovisco study
Henrotin Y, Chevalier X, Deberg M, Balblanc JC, Richette P, Mulleman D, Maillet B, Rannou F, Piroth C, Mathieu P, Conrozier T; Osteoarthritis Group of the French Society of Rheumatology. J Orthop Res. 2013 Jun;31(6):901-7. doi: 10.1002/jor.22297. Epub 2013 Feb 19.
Take Home Message: Hyaluronic acid injections decrease factors related to collagen degradation. Some blood tests may differentiate responders and nonresponders to these injections.
Knee osteoarthritis, one of the leading causes of disability, has no cure and current treatments commonly involve medications to decrease inflammation and pain. Hyaluronic acid (HA) injections have become a popular form of treatment for knee osteoarthritis. However, the mechanism of action has yet to be determined. Therefore, the authors examined serum biomarkers of collagen breakdown (Coll2-1 and Coll2-1 NO2) in 45 patients with various stages of knee osteoarthritis before (-15 days), at the time of injection, and following treatment (30 and 90 days) with HA injections.

Does an Individual’s Fitness Level Affect Baseline Concussion Symptoms?
Mrazik, M; Naidu, D; Lebrun, C; Game, A; Matthews-White, J. Journal of Athletic Training In-Press. doi: 10.4085/1062-6050-48.3.19
Take Home Message: Fitness level may influence baseline concussion symptom reporting with fitter individuals reporting fewer concussion symptoms. Athletes also appear to report more concussion symptoms when reporting after exercise.
Baseline testing in concussion management, including graded symptom assessment, has become commonplace in multiple sports on almost every level of competition. Different assessment tools (e.g., Sideline Concussion Assessment Tool [SCAT3], Immediate Post-Concussion Assessment and Cognitive Testing [ImPACT]) establish a baseline for many nonspecific symptoms so that post-injury symptoms may be compared to baseline results. Previous research has shown that multiple factors, including physical-activity level, can result in reports of more neurological symptoms. Therefore, Mrazik, et al sought to evaluate if an individual’s fitness level correlated with report of concussion symptoms at baseline. They hypothesized that after exertion, athletes with higher fitness levels would report fewer symptoms at baseline.

Knee and Ankle Osteoarthritis in Former Elite Soccer Players: A Systematic Review of the Recent Literature
Kujit MK, Inklaar H, Gouttebarge V, & Frings-Dresen MHW. Journal of Science and Medicine in Sport. 2012 15: 480 - 487.
Take Home Message: Elite soccer athletes may be at an increased risk for knee and ankle osteoarthritis compared with the general population. This group should be identified as high risk and preventative measures should be taken.
While participation in elite-level sports is often viewed as a good thing, there is an established increased risk of short-term injuries (e.g., sprains, strains). This increased injury risk may leave athletes at an increased risk for long-term disability (e.g., osteoarthritis [OA]). The purpose of this systematic review was to investigate the prevalence of knee and ankle OA among former elite-level soccer players.

Comparison of the balance accelerometer measure and balance error scoring system in adolescent concussions in sports
Furman G.T., Lin C-C., Ballanca, J.L., Marchetti G.F., Collins M.W., Whitney S.L. The American Journal of Sports Medicine. 2013; ahead of print.
Take Home Message: The balance error scoring system (BESS) test is more effective in assessing high school age students’ concussions compared to the Balance Accelerometer Measure (BAM) assessment. The tandem leg stances on firm and foam surface of the BESS test are the most sensitive and specific positions for the detection of a concussion.
Assessing balance after a concussion provides useful information not only for diagnosis and prognosis but also during the athlete’s return to play progression. Many clinicians evaluate balance with the balance error scoring system (BESS), which may be imprecise and susceptible to inter-rater error; however, it was specifically designed to assess concussion injuries. In contrast, the Balance Accelerometer Measure (BAM), which is assessed by the patient wearing small sensors, provides accurate balance assessments but was not designed to assess concussed athletes. Therefore, the purpose of this study was to compare the BAM test with the BESS test regarding the ability to detect differences in postural differences between 43 high school students with concussions compared to 27 age-matched controls.

Comparison of a laboratory grade force platform with a Nintendo Wii Balance Board on measurement of postural control in single-leg stance balance tasks.
Huurnink A, Fransz DP, Kingma I, and van Dieen JH. J Biomech. 2013; 46:1392-1395.
Take Home Message: The Wii Balance Board is an acceptable substitute for measuring the center of pressure during single leg stance balance tests.
While a laboratory grade force plate is the gold standard for both testing and training balance, these force plates are limited to research laboratories. Due to the importance of balance testing and training during the rehabilitation process, a cost effective, widely available and portable force plate is desirable. Therefore, Huurnink and colleagues compared a laboratory grade, in-floor force plate to the Wii Balance Board (WBB).

Nonsteroidal Anti-inflammatory Drug Use in Collegiate Football Players
Holmes N, Cronholm PF, Duffy AJ, Webner D. Clin J Sport Med. 2013. Epub ahead of print
Take Home Message: NSAIDs are a common treatment method for musculoskeletal injuries; however, over-the-counter availability, overuse, self-medication, and trends of initial use in high school may interfere with appropriate consumption among college athletes.
Nonsteroidal anti-inflammatory drugs (NSAIDs), a common treatment for athletic injuries, are generally safe medications when used short-term but can become problematic when used long-term and without oversight from a medical professional. There is a discrepancy between the amount of NSAIDs used in athletics and the number of studies that address their safety in athletics. In this cross-sectional study, Holmes et al. surveyed 211 collegiate football players at two institutions on two occasions (beginning of 2006 and 2009 seasons) regarding their NSAID use during the respective seasons.
