Simple Balance Test Is Able To Identify Non Contact Lower Extremity Injury Risk

Star Excursion Balance Test Anterior Asymmetry is Associated with Injury Status in Division I Collegiate Athletes

Stiffler MR, Bell DR, Sanfilippo JL, Hetzel SJ, Pickett KA, Heiderscheit BC. J Orthop Sports Phys Ther. 2017; 29:1-27.

Take Home Message: A clinician could use Star Excursion Balance Test anterior asymmetries to possibly differentiate collegiate athletes at greater risk for non-contact knee or ankle injury.

Clinicians use the Star Excursion Balance Test (SEBT) to identify athletes at risk for lower extremity injury. However, athletes’ performance on SEBT has been inconsistent across populations. Factors such as sex and type of sport the athlete plays may contribute to this discrepancy. It is unclear if these factors affect the relationship between SEBT score and risk of injury. Therefore, the authors retrospectively evaluated whether preseason SEBT scores from 147 healthy athletes were related to who experienced a non-contact knee or ankle injury during a season, while controlling for sport, sex, and athletic exposure (starter vs. non starter).

Athlete before Athletic: Consequences of Sport Specialization on Youth Athlete Health

The association of sport specialization and training volume with injury history in youth athletes.

Post EG, Trigsted SM, Riekena JW, Hetzel S, McGuine TA, Brooks MA.
Bell DR. Am J Sports Med. March 2017; [Epub ahead of print]

Take Home Message: An athlete engaged in highly specialized sport participation was more likely to report an injury within the previous year.

The positive benefits of youth sport participation are well-documented, but an emergence of specialized training among youth athletes has led to volume and frequency recommendations by professional medical organizations. These recommendations were well-intended but generated on limited evidence. The authors aimed to establish a relationship between sport specialization and injury history in youth athletes and identify the association of training volume recommendations and injury history.

Acute Care Needs to Focus More on Preventing Chronic Ankle Issues

Current Trends in the Management of Lateral Ankle Sprains in the United States

Feger MA, Glavniano NR, Donavan L, Hart JM, Saliba SA, Park JS, & Hertel J. Clin J Sport Med. 2017; 27:145-152. doi: 10.1097/JSM.0000000000000321

Take Home Message: Most common care after an ankle sprain involved multiple physician visits. Very few patients receive supervised rehabilitation. 

Lateral ankle sprains are one of the most common acute injuries among physically active individuals.  Ankle sprains cause short-term pain and disability and may cause long-term chronic ankle instability and joint damage.  Therefore, the question remains as to how ankle sprains are managed and whether the deficits exist due to initial management or if they develop after recovery from the primary injury.  The authors of this study aimed to describe lateral ankle sprain management within 30 day of injury using a database of national health insurance records in the United States for 2007 to 2011.

FIFA 11 ... (But Really FIFA 11 +) Programs Are Effective in Reducing Football (Soccer) Injuries

Effect of specific exercise-based football injury prevention programmes on the overall injury rate in football: a systematic review and meta-analysis of the FIFA 11 and 11+ programmes

Thorborg K, Krommes KK, Esteve E, Clausen MB, Bartels EM, Rathleff MS. Br J Sports Med. 2017 Apr;51(7):562-571. doi: 10.1136/bjsports-2016-097066. Epub 2017 Jan 13.

Take Home Message: The FIFA 11+ program reduces injury rates in recreational and sub-elite soccer players.

There are a variety of training programs to prevent injury in athletics, particularly in soccer. Many of these programs target anterior cruciate ligament (ACL) injury prevention but these programs are also able to reduce the risk of injury in general. The FIFA Medical Assessment and Research Centre (F-MARC) created the FIFA 11 and 11+ programs to reduce injury and allow for continued participation in soccer. While various investigators have implemented these programs, their effects on injury have been conflicting. Therefore, the authors conducted a meta-analysis to pool data from individual studies to increase our ability to precisely estimate the possible effects of these programs.

Elbow Stress May Compromise Elbow Health

Risk factors for cartilage damage and osteoarthritis of the elbow joint: case-control study and systematic literature review

Spahn G, Lipfert JU, Maurer C, Hartmann B, Schiele R, Holm Torsten K, Gifka J, Hofmann GO. Arch Orthop Trauma Surg. 2017; 137(4):557-566

Take Home Message: Workers and athletes exposed to greater elbow stress (from vibration, high forces, or high repetition) may be more likely to develop elbow osteoarthritis. 

Elbow anatomy is complex and the joint is often put under mechanical stress.  This stress spans across both sexes and many occupations, from athletics to construction or assembly. Review of the literature fails to demonstrate if osteoarthritis (OA) of the elbow joint is related to trauma, age-related changes, occupation, or if there is no relationship between OA and these possible risk factors. Therefore, Spahn and colleagues reviewed previous research and conducted a case-control study to compare people with no elbow joint issues to a group of patients who experienced chronic symptoms that required elbow surgery.

Don’t Let Your Concussed Athletes Spin Out of Control; PT is Feasible!

Feasibility of Early Physical Therapy for Dizziness After a Sports-Related Concussion: A Randomized Clinical Trial

Reneker JC, Hassen A, Phillips RS, Moughiman MC, Donaldson M, Moughiman J. Scand J Med Sci Sports. 2017; ahead of print.

Take Home Message:  Closely supervised cervical and vestibular ocular therapy may help safely return concussed athletes to play.

Dizziness is one of the most common symptoms reported following a concussion. Clinicians can use rehabilitative techniques to treat dizziness; however, it remains unknown whether these techniques are safe and effective for patients suffering dizziness following an acute concussion. Therefore, the authors developed a double-blind, randomized control feasibility trial to assess treatment benefits, patient retention, protocol management, and participant safety between 2 treatment strategies.

Possible Keys For Running Away From Injury

A Prospective Comparison of Lower Extremity Kinematics and Kinetics Between Injured and Non-Injured Collegiate Cross Country Runners

Dudley RI, Pamukoff DN, Lynn SK, Kersey RD, & Noffal GJ. Human Movement Science. 2017; 52:197-202. doi: 10.1016/j.humov.2017.0.007

Take Home Message: Cross country runners who developed a running-related injury during a season had greater knee valgus and ankle eversion velocity before the season started compared with runners who remained injury free. 

Running is generally considered to have many positive benefits; however, runners are at greater risk for injury due to the repetitive loads associated with running.  It remains unclear if a runner’s biomechanics may predispose them to a running-related injury. Hence, the researchers in this specific prospective study followed collegiate cross country runners with a goal to identify factors related to a new running-related injury.
