Implementation of the 2017 Berlin Concussion in Sport Group Consensus Statement in contact and collision sports: a joint position statement from 11 national and international sports organisations

Implementation of the 2017 Berlin Concussion in Sport Group Consensus Statement in contact and collision sports: a joint position statement from 11 national and international sports organisations

Br J Sports Med.

In July 2017, representatives from 10 sports and 11 sports governing bodies/federations met to examine, develop and implement practical, sport-specific strategies for diagnosing and managing concussion across varying ages and levels of participation. Major sections of the consensus statement cover defining and diagnosing concussion, using video technology, return to sport recommendations, independence in the concussion management process, practical implementation and translation of concussion management protocols, as well as concussion awareness and education.

Prescreenings as Possible Genesis of I Can’t Dance

Risk factors for musculoskeletal injury in elite-professional modern dancers: A prospective cohort prognostic study

Bronner S & Bauer NG. Physical Therapy in Sports. 2018; Online Ahead of Print January xx, 2018.  Doi: 10/1016/j.ptsp.2018.01.008

Take Home Message: Dancers who had low or high hypermobility score, muscular tightness, poorer technique, or a recent injury history (as assessed through preparticipation screening) had higher injury risk.
Clinicians are increasingly using screening visits to determine injury risk in many settings/sports, and this includes elite-modern dancers.  The extreme demands of dance may predispose someone to injury; but, we know very little about risk factors for dance-related injuries.  Therefore, the authors of this study retrospectively investigated some common risk factors (hypermobility, technique, muscular tightness, recent injury history) among participants in a university modern dance program.

2018 International Olympic Committee consensus statement on prevention, diagnosis and management of paediatric anterior cruciate ligament (ACL) injuries

2018 International Olympic Committee consensus statement on prevention, diagnosis and management of paediatric anterior cruciate ligament (ACL) injuries.

Ardern CL, Ekås G, Grindem H, Moksnes H, Anderson A, Chotel F, Cohen M, Forssblad M, Ganley TJ, Feller JA, Karlsson J, Kocher MS, LaPrade RF, McNamee M, Mandelbaum B, Micheli L, Mohtadi N, Reider B, Roe J, Seil R, Siebold R, Silvers-Granelli HJ, Soligard T, Witvrouw E, Engebretsen L. Knee Surg Sports Traumatol Arthrosc. 2018 Feb 17. doi: 10.1007/s00167-018-4865-y. [Epub ahead of print]

The International Olympic Committee organized a meeting of an international panel of physiotherapists and orthopedic surgeons who specialize in treating and researching pediatric anterior cruciate ligament (ACL) injuries to develop a consensus statement on the prevention, diagnosis, and management of pediatric ACL injuries. The key sections cover injury prevention (e.g., 11+ for kids program, factors that impact injury prevention effectiveness); diagnosis, clinical tests, and imaging; treatment of ACL injuries (e.g., rehabilitation, surgical techniques); treatment decision modifiers; pediatric patient-reported outcomes; ethical considerations; and future research.

Pecking Away at the Truth about Woodpecker Brains’ Resistance to Brain Injury

Tau accumulations in the brains of woodpeckers.

Farah G, Siwek D, Cummings P. PLoS One. 2018 Feb 2;13(2):e0191526

Take Home Message: Tau accumulations were seen in woodpeckers but not in control bird brains. This suggests that that pecking may induce the accumulation of tau in woodpecker brains.
Tau accumulation, which is associated with Alzheimer’s disease and chronic traumatic encephalopathy (CTE), may be a result of repetitive mild traumatic brain injury. Many believe that woodpeckers – who experience over 1000g’s while pecking – are resistant to neurotrauma and have become a model for head safety equipment (helmet). However, we have little evidence that woodpecker are resistant to repetitive head trauma. Therefore, the authors dissected the brains of previously preserved brain tissues of 10 woodpeckers and 5 control birds to observe for tau accumulation (neurofibrillary tangles) and axonal injury.

Following Guidelines to Prevent Exertional Heat Illness? Let’s Reconsider Those Guidelines

Fatal exertional heat stroke and American football players: The need for regional heat-safety guidelines.

Grundstein AJ, Hosokawa Y, and Casa DJ. J Athl Training. 2018. 53(1) 43-50.

Take Home Message: Regional activity modification guidelines may be more effective at preventing fatal exertional heat strokes than current guidelines.

Exertional heat illness is a potentially dangerous development during training in hot conditions, especially in football. While weather-based activity modification guidelines are intended to reduce the risk of exertional heat illness, these guidelines fail to account for regional geographic differences. Therefore, Grundstein and colleagues completed a retrospective study to determine if fatal exertional heat strokes among American football players occurred more frequently on days with abnormally high wet bulb globe temperatures (WBGTs) based on the local climate and to assess how regional activity-modification guidelines would have altered activity.

High School Ankle Sprain “Care”cteristics

Athletic Training Service Characteristics for Patients with Ankle Sprains Sustained During High School Athletics

Simon JE, Wikstrom EA, Grooms DR, Docherty CL, Dompier TP, Kerr ZY. J Athl Train. 2018;53(1):000–000, doi: 10.4085/1062-6050-449-16.

Take Home Message: High school athletic trainers commonly treat ankle sprains with therapeutic exercise and neuromuscular reeducation, with an increased number of services for athletes with time-loss ankle sprains.

Ankle sprains are prevalent among high school athletes and there is plentiful information on incidence and common factors associated with ankle sprains. However, less is known on how these athletes are treated by healthcare professionals. Thus, the authors conducted an analysis of the National Athletic Treatment, Injury, and Outcomes Network (NATION) data to determine what services were provided to high school athletes with time-loss and non-time-loss ankle sprains during 3 school years (2011-2014).

Hands on Approach to Massage Wins Over Instruments

Comparison of Compressive Myofascial Release and the Graston Technique for Improving Ankle-Dorsiflexion Range of Motion.

Stanek J, Sullivan T, Davis S. Journal of Athletic Training. 2018, 53(2):000-000. doi: 10.4085/1062-6050-386-16
Full Text Freely Available

Take Home Message: A single 5-minute compressive myofascial release treatment improved dorsiflexion range of motion more than instrument-assisted soft tissue mobilization.
Insufficient ankle dorsiflexion range of motion predisposes healthy individuals to lower extremity injuries. Clinicians use compressive myofascial release (CMR) or instrument-assisted soft tissue mobilization (IASTM) to target myofascial lesions in the triceps surae that limit ankle flexibility. However, there is little evidence to determine which method may be better at improving ankle dorsiflexion. Therefore, Stanek and colleagues performed a randomized controlled trial to assess the short-term effects of a single 5-minute session of CMR or IASTM (Graston technique) on the triceps surae for improving closed-chain ankle dorsiflexion range of motion among physically active people.
