Every Picture Tells A Story: Managing Exertional Heatstroke with Rotating Ice Water Towels

ABSTRACT

A 23-year-old woman completing her first marathon collapsed near the finish line at 4 hours 6 min with a rectal temperature of 41.8°C. She was in good health before the race with no recent illness, had completed a full training program, and was taking no medications or supplements. On the initial exam, she was unconscious with a response to painful stimulus, spontaneous breathing, rapid pulse, eyes closed, fully dilated pupils, poor muscle tone, and pale skin that was warm to touch. The medical team initiated whole-body cooling using rapidly rotating ice water towels and ice packs placed in the neck, axilla, and groin. She developed echolalia during active cooling. About 20 minutes into the cooling procedure, she "woke up," was able to answer questions coherently, and her pupils were normal size and reactive. She was discharged home with instructions to follow-up in 2 d for evaluation and blood chemistry testing.

Implementation of Exercise Management Services Among Sports Medicine Physicians in the United States

OBJECTIVE

Assessment of physical activity and exercise prescription has been widely supported by many organizations, yet provision of such services remains limited in the United States. We sought to uncover why such services have not been widely adopted.

DESIGN

The American Medical Society for Sports Medicine organized a task force to canvas physicians and survey the American Medical Society for Sports Medicine membership.

SETTING

Peer-to-peer and telecommunication discussions and web-based questionnaires.

PARTICIPANTS

Sports medicine physicians in the United States.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Percentage of sports medicine physicians who provide exercise management services and mechanisms of billing for exercise management, identify barriers to such services, and identify industry collaborations for promoting physical activity through physicians.

RESULTS

Three of 4 sports medicine physicians spend at least 1 min encouraging exercise with patients, using Evaluation and Management codes to bill or receive credit. Exercise counseling is often bundled within other patient care. Few health plans leverage the patient's relationship with a primary care physician to promote exercise. Most employed sports medicine physicians do not receive incentives to incorporate exercise counseling into practice, and only 1 in 6 have decision-making authority to hire an exercise professional. Major obstacles are the lack of a business model and knowledge about exercise prescription.

CONCLUSION

The existing E&M codes adequately characterize the work, but physicians desire greater payment or credit for providing exercise management services. Physicians desire to do more exercise prescription, but health system bureaucracy, inadequate support, and economic disincentives are barriers to the provision of exercise management services.

Mass Participation and Tournament Event Management for the Team Physician: A Consensus Statement (2022 Update)

ABSTRACT

Mass participation events include endurance events (e.g., marathon, triathlon) and/or competitive tournaments (e.g., baseball, tennis, football (soccer) tournaments). Event management requires medical administrative and participant care planning. Medical management provides safety advice and care at the event that accounts for large numbers of participants, anticipated injury and illness, variable environment, repeated games or matches, and mixed age groups of varying athletic ability. This document does not pertain to the care of the spectator.

Exertional calf pain at kilometer five - Finding the cause

A 23-year-old professional distance runner with several years of exertional calf pain was diagnosed with a unique mixed type III and functional popliteal artery entrapment syndrome (PAES). Surgical reduction of the obstructing tissue allowed her to return to professional running. This case highlights the importance of including PAES in the differential for chronic intermittent lower extremity claudication and outlines the work-up required to diagnose this vascular obstruction in younger athletes.

Bias and Conflict of Interest in the Underreporting of Sexual Abuse in Competitive Sports: A Literature Review

ABSTRACT

The prevalence of sexual abuse in competitive sports is increasing worldwide and requires a united call to action. The underreporting of such abuses gained media attention resulting from recent high-profile cases. In this article, we report the results of a systematic literature review, identifying root causes of underreporting sexual abuse in competitive sports. We identify that biases and conflicts of interest work against effective reporting of abuse by athletes at the individual, organizational, and cultural levels. We offer conflict of interest and bias mitigation approaches from the social science, law, business, research, and diagnostic error literature that may apply. Competitive sports organizations may use this analysis to identify barriers and improve the effective reporting of sexual abuse.

A Pilot Study: Do Children Who Run Marathons Have More Osteoarthritis in the Lower Extremities as Adults

OBJECTIVE

To compare self-reported osteoarthritis of the knee and hip in adults who ran at least 1 marathon as a child with adults who ran high-school cross country (HSCC).

DESIGN

Subject self-recall retrospective survey.

SETTING

Electronic survey.

PARTICIPANTS

319 adults who either ran a marathon under age 18 or ran HSCC recruited from running clubs, marathon participants, and on-line interest groups.

INTERVENTIONS

Survey.

MAIN OUTCOME MEASURES

Self-reported history of osteoarthritis (OA), joint pain, anterior cruciate ligament injury, still running or running marathons, and number of marathons as an adult.

RESULTS

One hundred twenty-three respondents ran a marathon under age 18 (26% female) and were 40 years old (sd 16) and 196 ran HSCC (53% female) and were 36 years old (sd 13). The mean age of first marathon was 15 (sd 2.3, range 5-17); 50% ran 1% and 50% ran >1 marathon. Child marathoners reported a family history of OA in knees or hips (26%) or a joint replacement (30%) compared with 24% and 28% of HSCC runners. 10% of child marathoners and 7% of HSCC reported OA and 24% and 21% reported daily or weekly joint pain. 91% of all respondents are still running; 78% of child marathoners (mean 17, range 1-91) and 80% HSCC ran ≥1 marathons as adults (mean 10, range 1-80).

CONCLUSIONS

Adults who ran marathons as children compared with adults who ran HSCC self-report similar rates of the knee and hip OA, chose to participate of their own accord, continue to run as adults, played other sports, and did not "specialize" in marathons.

ACSM Expert Consensus Statement on Exertional Heat Illness: Recognition, Management, and Return to Activity

ABSTRACT

Exertional heat stroke is a true medical emergency with potential for organ injury and death. This consensus statement emphasizes that optimal exertional heat illness management is promoted by a synchronized chain of survival that promotes rapid recognition and management, as well as communication between care teams. Health care providers should be confident in the definitions, etiologies, and nuances of exertional heat exhaustion, exertional heat injury, and exertional heat stroke. Identifying the athlete with suspected exertional heat stroke early in the course, stopping activity (body heat generation), and providing rapid total body cooling are essential for survival, and like any critical life-threatening situation (cardiac arrest, brain stroke, sepsis), time is tissue. Recovery from exertional heat stroke is variable and outcomes are likely related to the duration of severe hyperthermia. Most exertional heat illnesses can be prevented with the recognition and modification of well-described risk factors ideally addressed through leadership, policy, and on-site health care.

Running-related injuries in middle school cross-country runners: Prevalence and characteristics of common injuries

BACKGROUND

Understanding the prevalence and factors associated with running-related injuries in middle school runners may guide injury prevention.

OBJECTIVE

To determine the prevalence of running-related injuries and describe factors related to a history of injury.

DESIGN

Retrospective cross-sectional study.

SETTING

Survey distributed online to middle school runners.

METHODS

Participants completed a web-based survey regarding prior running-related injuries, training, sleep, diet, and sport participation.

MAIN OUTCOME MEASUREMENTS

Prevalence and characteristics differentiating girls and boys with and without running-related injury history adjusted for age.

PARTICIPANTS

Youth runners (total: 2113, average age,  13.2 years; boys: n = 1255, girls: n = 858).

RESULTS

Running-related injuries were more prevalent in girls (56% vs. 50%, p = .01). Ankle sprain was the most common injury (girls: 22.5%, boys: 21.6%), followed by patellofemoral pain (20.4% vs. 7.8%) and shin splints (13.6% vs. 5.9%); both were more prevalent in girls (p < .001). Boys more frequently reported plantar fasciitis (5.6% vs. 3.3%, p = .01), iliotibial band syndrome (4.1% vs. 1.4%, p = .001) and Osgood-Schlatter disease (3.8% vs. 1.2%, p = .001). Runners with history of running-related injuries were older, ran greater average weekly mileage, ran faster, had fewer average hours of sleep on weekends, skipped more meals, missed breakfast, and consumed less milk (all p < .05). Girls with history of running-related injuries reported higher dietary restraint scores, later age of menarche, more menstrual cycle disturbances, and higher likelihood of following vegetarian diets and an eating disorder diagnosis (all p < .05). Runners with no history of running-related injuries were more likely to have participated in ≥2 years of soccer or basketball (p < .001).

CONCLUSIONS

Most middle school runners reported a history of running-related injuries and certain injuries differing by gender. Modifiable factors with the greatest association with running-related injuries included training volume, dietary restraint, skipping meals, and less sleep. Sport sampling, including participation in ball sports, may reduce running-related injury risk in this population.

Exertional heat stroke: An evidence based approach to clinical assessment and management

NEW FINDINGS

What is the topic of this review? The treatment of exertional heat stress, from initial field care through the return-to-activity decision, is reviewed. What advances does it highlight? Clinical assessment during field care using AVPU and vital signs to gauge recovery Approaches to field cooling and end of active cooling Shared clinical decision making for return to activity recommendations ABSTRACT: Exertional heat stroke (EHS) is a potentially fatal condition characterized by central nervous system dysfunction and body temperature often but not always >40°C that occurs in the context of physical work in warm or hot environments. In this paper, we review the continuum of care, from initial recognition and field care to transport and hospital care, and finally return to duty considerations. Morbidity and mortality can be greatly reduced if not eliminated with prompt recognition and aggressive cooling. If medical personnel are not present at point of collapse during or immediately following exercise, EHS should be the presumptive diagnosis until a formal diagnosis can be determined by qualified medical staff. EHS is the rare medical situation where initial treatment (cooling) takes precedence over transport to a medical facility, where advanced medical care may be required for severe EHS casualties. Recovery from EHS and return to activity is usually straightforward and unremarkable provided the casualty is rapidly cooled at time of collapse and adequate time is allowed for body healing. However, evidence-based data to guide return to activity following EHS is limited. Current research suggests that most individuals recover completely within a few weeks though some individuals may suffer prolonged sequalae and additional evaluation may be warranted, including heat tolerance testing. Several aspects of the care of the EHS casualty are based on best practices derived from personal experience and continued research is necessary to optimize evaluation and management.

COVID-19-Positive Testing in Minnesota High School Fall and Winter Sports: A Guide for Sports Risk

OBJECTIVE

To assess the effectiveness of coronavirus disease 2019 (COVID-19) prevention strategies used during sports participation.

DESIGN

To analyze prospective reports of student-athletes with COVID-19-positive tests to assess prevention strategies and risk factors by sports and seasons.

SETTING

Minnesota high schools.

PARTICIPANTS

Fall 2020 (August 24-October 30) and winter 2021 (January 2-March 12) student-athletes.

ASSESSMENT OF RISK FACTORS

Sports, indoor location, mask use, physical distancing, and season.

MAIN OUTCOME MEASURES

COVID-19-positive test rates.

METHODS

Self-selected schools voluntarily reported, in 2-week intervals, the number of student-athletes with COVID-19-positive tests in each sport and the number of athletes participating in each sport during the fall and winter sports seasons. The positive testing rates per 100 000 athletes were calculated for participants in each sport and compared by sports type and risk variables.

RESULTS

The high school age community-positive testing rate was 1298 per 100 000 students in the fall and 2396 in the winter. The student-athlete positive testing rate was 1500 per 100 000 athletes during the fall and 2800 during the winter (χ2 = 1.98, df = 1, P = 0.350). Positive tests per 100 000 athletes ranged from 197 (girls alpine skiing) to 4151 (wrestling). The incidence rates comparing indoor with outdoor sports (P = 0.001) and close-contact with physically distanced sports (P = 0.023) were significantly different, but the incidence rates comparing indoor masked with unmasked sports (P = ns) were not different.

CONCLUSION

Athletes competing in outdoor individual sports have less risk of a COVID-19-positive test compared with age-matched individuals in the community and indoor sports participants either wearing or not wearing masks during competition. Unmasked athletes in close proximity have the highest positive test rates, and unenforced masking is not associated with lower positive testing rates. More study is needed to understand mask effectiveness.

COVID Vaccination in Athletes and Updated Interim Guidance on the Preparticipation Physical Examination During the SARS-Cov-2 Pandemic

The group held a series of meetings beginning in July 2021 and reviewed the available literature while using an iterative process and expert consensus to finalize this guidance statement. This document is intended to provide clinicians with suggestions on how to incorporate the COVID vaccination during the preparticipation physical examination for athletes in all levels of training and competition. The statement is not intended to address treatment, infection control principles, safety, ethical discussion, or public health issues related to SARS-CoV-2. The AMSSM task force acknowledges the clinical uncertainty, evolving public health objectives, and the limited data currently available to create this guidance statement.

Mental Health Aspects of Voluntary and Involuntary Sport Retirement

ABSTRACT

Sports participation is an important factor in the mental health of athletes. A change in sports participation affects athlete mental health, in addition to other components of the athlete's life, including overall health and fitness, future career plans, current and future financial status, and available social network. Athletes should be encouraged to develop balanced lives that involve rewarding activities outside their sport. Clinicians should evaluate the mental health of athletes leaving sport for any reason, develop protocols to address any concerns, and assist with postsport career and life planning.

Burden of Injury and Illness in the Road Race Medical Tent: A Narrative Review

OBJECTIVE

To summarize the literature relating to prehospital care at 5 km through marathon distance road races and present the epidemiology of common medical encounters, significant medical complications, and medical outcomes.

DATA SOURCES

We searched PubMed and Google Scholar for the published literature pertaining to road race medical tent encounters at 5 km through marathon distance road races from 2000 to 2018. We included English-language, original articles reporting on injury and illness incidence.

MAIN RESULTS

Standard medical encounter definitions have recently been formulated in response to the previous lack of uniform definitions. The incidence of medical complications at road races may be influenced by environmental conditions and race distance. Minor and moderate medical encounters, such as dermatologic injuries, musculoskeletal injuries, and exercise-associated collapse, are common. Serious and life-threatening medical complications, including exertional heat stroke, exercise-associated hyponatremia, and cardiac arrest, are less frequent. Fatalities are also rare, with rates of 0.3 to 5 per 100 000 participants reported at marathons. The ratio of hospital transports to medical encounters is low.

CONCLUSIONS

On-site medical services play a key role in the safety of both runners and the community. Future research and care initiatives in this field should focus on optimizing treatment protocols, promoting injury prevention efforts and reducing host community costs.

The Collaborative Scholarship Intensive: A Research-Intensive Course to Improve Faculty Scholarship

BACKGROUND AND OBJECTIVES

Learning to balance the clinical, educational, and scholarly elements of an academic career is challenging for faculty. To increase research output amongst family medicine faculty with limited to no publications, we developed the Collaborative Scholarship Intensive (CSI) to provide participants with intensive instruction in research methodology coupled with structured writing support and protected time for writing.

METHODS

The CSI was developed by the University of Minnesota Department of Family Medicine and Community Health as a six-session faculty development program that enrolled 23 participants in its first three classes.

RESULTS

Findings reveal that faculty participants significantly improved their pre- to postcourse self-ratings of 12 research competencies, and significantly increased their scholarly output.

CONCLUSIONS

Our CSI faculty development program successfully engaged clinical faculty in a collaborative research program. Our results suggest that a program focused on intensive instruction in research methodology coupled with structured writing support and protected writing time may be a model for faculty development in other academic departments.

Proceedings From the Ice Hockey Summit III: Action on Concussion

OBJECTIVES

The Ice Hockey Summit III provided updated scientific evidence on concussions in hockey to inform these 5 objectives: (1) describe sport related concussion (SRC) epidemiology; (2) classify prevention strategies; (3) define objective, diagnostic tests; (4) identify treatment; and (5) integrate science and clinical care into prioritized action plans and policy.

METHODS

Our action plan evolved from 40 scientific presentations. The 155 attendees (physicians, athletic trainers, physical therapists, nurses, neuropsychologists, scientists, engineers, coaches, and officials) voted to prioritize these action items in the final Summit session.

RESULTS

To (1) establish a national and international hockey database for SRCs at all levels; (2) eliminate body checking in Bantam youth hockey games; (3) expand a behavior modification program (Fair Play) to all youth hockey levels; (4) enforce game ejection penalties for fighting in Junior A and professional hockey leagues; (5) establish objective tests to diagnose concussion at point of care; and (6) mandate baseline testing to improve concussion diagnosis for all age groups.

CONCLUSIONS

Expedient implementation of the Summit III prioritized action items is necessary to reduce the risk, severity, and consequences of concussion in the sport of ice hockey.

Integrating Transwomen and Female Athletes with Differences of Sex Development (DSD) into Elite Competition: The FIMS 2021 Consensus Statement

Sport is historically designated by the binary categorization of male and female that conflicts with modern society. Sport’s governing bodies should consider reviewing rules determining the eligibility of athletes in the female category as there may be lasting advantages of previously high testosterone concentrations for transwomen athletes and currently high testosterone concentrations in differences in sex development (DSD) athletes. The use of serum testosterone concentrations to regulate the inclusion of such athletes into the elite female category is currently the objective biomarker that is supported by most available scientific literature, but it has limitations due to the lack of sports performance data before, during or after testosterone suppression. Innovative research studies are needed to identify other biomarkers of testosterone sensitivity/responsiveness, including molecular tools to determine the functional status of androgen receptors. The scientific community also needs to conduct longitudinal studies with specific control groups to generate the biological and sports performance data for individual sports to inform the fair inclusion or exclusion of these athletes. Eligibility of each athlete to a sport-specific policy needs to be based on peer-reviewed scientific evidence made available to policymakers from all scientific communities. However, even the most evidence-based regulations are unlikely to eliminate all differences in performance between cisgender women with and without DSD and transwomen athletes. Any remaining advantage held by transwomen or DSD women could be considered as part of the athlete’s unique makeup.

Recommendations on Youth Participation in Ultra-Endurance Running Events: A Consensus Statement

Participation in ultra-endurance running (UER) events continues to grow across ages, including youth athletes. The 50- and 100-km are the most popular distances among youth athletes. Most youth athletes are between 16-18 years; however, some runners younger than 12 years have successfully completed UER events. Parents, athletes, coaches, race directors, and medical professionals often seek advice regarding the safety of youth athletes participating in these events, especially with regard to potential short and long-term health consequences. UER may impact key organ systems during growth and development. We propose a decision-making process, based on current knowledge and the experience of the consensus group that addresses age regulations, medical and psychological well-being, training status and race-specific factors (such as distance, elevation change, remoteness, ambient temperatures, level of medical assistance, and type of provisions provided by the race organizers) to use until evidence of long-term consequences of UER in youth athletes is available. These recommendations are aimed at safe participation in UER events for youth athletes with a proper and individualized assessment.

Interim Guidance on the Preparticipation Physical Examination for Athletes During the SARS-CoV-2 Pandemic

The American Medical Society for Sports Medicine (AMSSM) convened a writing group to address the current evidence and knowledge gaps regarding preparticipation evaluation of athletes during the SARS-CoV2 pandemic. The writing group held a series of meetings beginning in April 2020. The task force reviewed the available literature and used an iterative process and expert consensus to finalize this guidance statement that is intended to provide clinicians with a clinical framework to return athletes of all levels to training and competition during the pandemic. The statement is not intended to address treatment, infection control principles, or public health issues related to SARS-CoV2. The AMSSM task force acknowledges the clinical uncertainty, evolving public health objectives, and the limited data currently available to create this guidance statement.

Prevention of Sport-Related Concussion

Concussion remains a common injury among sports participants. Implementing risk-reduction strategies for sport-related concussion (SRC) should be a priority of medical professionals involved in the care of athletes. Over the past few decades, a multifaceted approach to reducing SRC risk has been developed. Protective equipment, rule and policy change/enforcement, educational programs, behavioral modifications, legislation, physiologic modifications, and sport culture change are a few of the programs implemented to mitigate SRC risk. In this article, the authors critically review current SRC risk-reduction strategies and offer insight into future directions of injury prevention for SRC.

Youth running consensus statement: minimising risk of injury and illness in youth runners

Despite the worldwide popularity of running as a sport for children, relatively little is known about its impact on injury and illness. Available studies have focused on adolescent athletes, but these findings may not be applicable to preadolescent and pubescent athletes. To date, there are no evidence or consensus-based guidelines identifying risk factors for injury and illness in youth runners, and current recommendations regarding suitable running distances for youth runners at different ages are opinion based. The International Committee Consensus Work Group convened to evaluate the current science, identify knowledge gaps, categorise risk factors for injury/illness and provide recommendations regarding training, nutrition and participation for youth runners.

The COVID-19 pandemic and physical activity

The SARS-CoV-2-caused COVID-19 pandemic has resulted in a devastating threat to human society in terms of health, economy, and lifestyle. Although the virus usually first invades and infects the lung and respiratory track tissue, in extreme cases, almost all major organs in the body are now known to be negatively impacted often leading to severe systemic failure in some people. Unfortunately, there is currently no effective treatment for this disease. Pre-existing pathological conditions or comorbidities such as age are a major reason for premature death and increased morbidity and mortality. The immobilization due to hospitalization and bed rest and the physical inactivity due to sustained quarantine and social distancing can downregulate the ability of organs systems to resist to viral infection and increase the risk of damage to the immune, respiratory, cardiovascular, musculoskeletal systems and the brain. The cellular mechanisms and danger of this "second wave" effect of COVID-19 to the human body, along with the effects of aging, proper nutrition, and regular physical activity, are reviewed in this article.

Controversies in exertional heat stroke diagnosis, prevention, and treatment

During the past several decades, the incidence of exertional heat stroke (EHS) has increased dramatically. Despite an improved understanding of this syndrome, numerous controversies still exist within the scientific and health professions regarding diagnosis, pathophysiology, risk factors, treatment, and return to physical activity. This review examines the following eight controversies: 1) reliance on core temperature for diagnosing and assessing severity of EHS; 2) hypothalamic damage induces heat stroke and this mediates “thermoregulatory failure” during the immediate recovery period; 3) EHS is a predictable condition primarily resulting from overwhelming heat stress; 4) heat-induced endotoxemia mediates systemic inflammatory response syndrome in all EHS cases; 5) nonsteroidal anti-inflammatory drugs for EHS prevention; 6) EHS shares similar mechanisms with malignant hyperthermia; 7) cooling to a specific body core temperature during treatment for EHS; and 8) return to physical activity based on physiological responses to a single-exercise heat tolerance test. In this review, we present and discuss the origins and the evidence for each controversy and propose next steps to resolve the misconception.

Youth Distance Running: Strategies for Training and Injury Reduction

Running is a popular sport for children in the United States. However, review of available literature on health effects and safety recommendations for youth running has not been previously conducted. Unique factors for injury include periods of growth during puberty and potential for growth plate injury. Youth runners may benefit from activities that incorporate high-impact loading and multidirectional movement for optimal bone maturation, exercises to strengthen tendons and muscles, and strategies aimed at improving running biomechanics to reduce risk of injury. In addition, addressing lifestyle factors, including nutrition and sleep is essential for a runner's general health. Similar to other sports, sports specialization should not be encouraged in youth runners. Reducing running-related injury in growing children and assessing readiness for running should be based on a combination of physical, emotional, psychological, social, and cognitive factors. Youth runners require individualized training and competition to safely participate in the sport.

Medical encounters (including injury and illness) at mass community-based endurance sports events: an international consensus statement on definitions and methods of data recording and reporting

Mass participation endurance sports events are popular but a large number of participants are older and may be at risk of medical complications during events. Medical encounters (defined fully in the statement) include those traditionally considered 'musculoskeletal' (eg, strains) and those due to 'illness' (eg, cardiac, respiratory, endocrine). The rate of sudden death during mass endurance events (running, cycling and triathlon) is between 0.4 and 3.3 per 100 000 entrants. The rate of other serious medical encounters (eg, exertional heat stroke, hyponatraemia) is rarely reported; in runners it can be up to 100 times higher than that of sudden death, that is, between 16 and 155 per 100 000 race entrants. This consensus statement has two goals. It (1) defines terms for injury and illness-related medical encounters, severity and timing of medical encounters, and diagnostic categories of medical encounters, and (2) describes the methods for recording data at mass participation endurance sports events and reporting results to authorities and for publication. This unifying consensus statement will allow data from various events to be compared and aggregated. This will inform athlete/patient management, and thus make endurance events safer.

American Medical Society for Sports Medicine position statement on concussion in sport

Sport-related concussion (SRC) is a common injury in recreational and organised sport. Over the past 30 years, there has been significant progress in our scientific understanding of SRC, which in turn has driven the development of clinical guidelines for diagnosis, assessment and management of SRC. In addition to a growing need for knowledgeable healthcare professionals to provide evidence-based care for athletes with SRC, media attention and legislation have created awareness and, in some cases, fear about many issues and unknowns surrounding SRC. The American Medical Society for Sports Medicine (AMSSM) formed a writing group to review the existing literature on SRC, update its previous position statement, and to address current evidence and knowledge gaps regarding SRC. The absence of definitive outcomes-based data is challenging and requires relying on the best available evidence integrated with clinical experience and patient values. This statement reviews the definition, pathophysiology and epidemiology of SRC, the diagnosis and management of both acute and persistent concussion symptoms, the short-term and long-term risks of SRC and repetitive head impact exposure, SRC prevention strategies, and potential future directions for SRC research. The AMSSM is committed to best clinical practices, evidence-based research and educational initiatives that positively impact the health and safety of athletes.

Eliminating Fighting and Head Hits from Hockey: Opportunities and Barriers

Removing fighting from ice hockey is an essential concussion prevention strategy that will improve the safety of the game at all levels.
