Catastrophic High School and Collegiate Cheerleading Injuries in the United States: An Examination of the 2006-2007 Basket Toss Rule Change

Safety in Cheerleading: Epidemiology and Recommendations: Policy Statement

Participation in cheerleading has continued to increase over the last decade, and the sport has evolved to require a higher level of athleticism. More than 3.5 million youth currently participate, with the vast majority being females between the ages of 6 and 17 years. Cheer occurs in both scholastic and nonscholastic settings; participants may perform to support other interscholastic teams or engage in competitions to showcase their skills against other squads. With the increased athletic demands of the sport and the year-round nature of competition, the number of injuries, including concussions, has risen. The overall injury rate for cheer is fairly low, but average time away from sport after injury is lengthy suggesting injuries can be severe. This policy statement reviews the epidemiology of cheerleading injuries and offers recommendations on how to improve the safety of cheerleading for all youth.

Catastrophic Sports Injuries: Causation and Prevention

➤ Catastrophic injuries in U.S. high school and college athletes are rare but devastating injuries.➤ Catastrophic sports injuries are classified as either traumatic, caused by direct contact during sports participation, or nontraumatic, associated with exertion while participating in a sport.➤ Football is associated with the greatest number of traumatic and nontraumatic catastrophic injuries for male athletes, whereas cheerleading has the highest number of traumatic catastrophic injuries and basketball has the highest number of nontraumatic catastrophic injuries for female athletes.➤ The incidence of traumatic catastrophic injuries for all sports has declined over the past 40 years, due to effective rule changes, especially in football, pole-vaulting, cheerleading, ice hockey, and rugby. Further research is necessary to reduce the incidence of structural brain injury in contact sports such as football.➤ The incidence of nontraumatic catastrophic injuries has increased over the last 40 years and requires additional research and preventive measures. Avoiding overexertion during training, confirming sickle cell trait status in high school athletes during the preparticipation physical examination, and developing cost-effective screening tools for cardiac abnormalities are critical next steps.

Prevalence of Suspected Concussions Among K-12 Students in Utah: Findings From Utah's Student Injury Reporting System

BACKGROUND

To inform prevention strategies, this study provides incidence, factors, and actions taken when a suspected concussion occurred in K-12 schools in Utah.

METHODS

Data were collected using Utah's Student Injury Reporting System (SIRS) from the academic years 2011-2012 to 2018-2019. SIRS is a unique online system that tracks injuries that occur in the school setting among K-12 students in Utah. Descriptive statistics were computed to characterize students with a suspected concussion. Chi-square (χ² ) analysis looking at characteristics by school level was also conducted.

RESULTS

Over 63,000 K-12 students in Utah sustained an injury at school during the study period. Suspected concussions comprised 10% of all injuries. The prevalence of concussions was highest among males (60.6%) and elementary school students (42.6%) and most often occurred outdoors (57.6%) or on a playground/playfield (33.9%), and in sports- and recreation-related activities (75.1%) (specifically contact sports, 24.0%). Most students with a suspected concussion were absent 1 day or less from school (71.4%) but about 68% were seen by a medical professional. Further, there were differences by school level. Females and students playing contact sports had a higher percentage of suspected concussions as school level increased, whereas males and concussions sustained during school hours had a lower percentage of suspected concussions as school level increased.

CONCLUSIONS

SIRS enables schools in Utah to identify groups at risk for concussion, as well as activities most commonly associated with these injuries, within the school environment. Using this information, schools may implement targeted prevention strategies to protect students.

Understanding the Cheerleader as an Orthopaedic Patient: An Evidence-Based Review of the Literature

Cheerleading is a highly popular youth sport in the United States and has been increasingly recognized in recent years for its athleticism and competitive nature. The sport has changed dramatically since its inception. When the sport of cheerleading was first developed, its primary purpose was to entertain crowds and support other athletes. Today, cheerleaders are competitive athletes themselves. Cheerleaders, most of whom are in the pediatric age group, and their parents commonly approach orthopaedic surgeons and sports medicine physicians with questions regarding the risks associated with participation in the sport. Appropriate clinical guidance is especially important for athletes returning to the sport after an injury. However, unlike other popular sports (eg, football, basketball, and volleyball), the intricacies of cheerleading are not well-known to those outside the sport, including many health care providers. Previous studies have reported on the epidemiological patterns of injuries associated with cheerleading and how such aesthetic sports affect the body, finding that fractures and concussions are prevalent and that catastrophic injuries are more common than in most other sports. Here, we provide an evidence-based discussion of 10 pertinent topics regarding cheerleading and its risks to the musculoskeletal system. The purpose of this review is to provide a comprehensive resource for orthopaedic surgeons and sports medicine physicians who care for these athletes.

Progress in Cheerleading Safety: Update on the Epidemiology of Cheerleading Injuries Presenting to US Emergency Departments, 2010-2019

Background

Although the athleticism required of cheerleaders has increased, the risks of cheerleading have been less studied as compared with other sports.

Purpose

To update our understanding of the epidemiology of cheerleading-related injuries.

Study Design

Descriptive epidemiology study.

Methods

We analyzed the National Electronic Injury Surveillance System (NEISS) for cheerleading-related injuries presenting to nationally representative emergency departments (EDs) in the United States from January 2010 through December 2019. Extracted data included patient age and sex, injury characteristics (diagnosis, body region injured, time of year, and location where injury occurred), and hospital disposition. Using patient narratives, we recorded the cheerleading skills, settings, and mechanisms that led to injury. NEISS sample weights were used to derive national estimates (NEs) from actual case numbers.

Results

From 2010 to 2019, a total of 9868 athletes (NE = 350,000; 95% CI, 250,000-450,000) aged 5-25 years presented to US EDs for cheerleading injuries. The annual number of injuries decreased by 15%, from 982 (NE = 35,000; 95% CI, 27,000-44,000) to 897 (NE = 30,000; 95% CI, 18,000-42,000) (P = .048), corresponding to a 27% decline in the injury rate per 100,000 cheerleaders (P < .01). The annual number of injuries caused by performing stunts decreased by 24%, from 240 (NE = 8700; 95% CI, 6700-11,000) to 216 (NE = 6600; 95% CI, 4000-9200) (P = .01), with a 36% decline in the corresponding injury rate per 100,000 cheerleaders (P < .01). Despite these decreases, annual incidence of concussions/closed head injuries increased by 44%, from 128 (NE = 3800; 95% CI, 2900-4700) to 171 (NE = 5500; 95% CI, 3400-7700) (P = .02), and patients requiring hospital admission increased by 118%, from 18 (NE = 330; 95% CI, 250-410) to 24 (NE = 720; 95% CI, 440-1000) (P < .01). The hospital admission rate increased by 9.0% (P = .02).

Conclusion

The number of cheerleading-related injuries presenting to US EDs decreased from 2010 to 2019. However, the incidence of concussions/closed head injuries and hospital admissions increased, suggesting that further measures are needed to improve safety for cheerleaders.

Epidemiology of Sport-Related Concussion

Sport-related concussions are common in the United States. Concussion rates have increased over time, likely due to improved recognition and awareness. Concussion rates vary across level (high school vs college), sex, and sport. Concussion rates are the highest among men, particularly in football, wrestling, ice hockey, and lacrosse where collisions and contact are inherent to the sports, although girls'/women's soccer rates are high. In gender-comparable sports, women have higher concussion rates. Continued data collection will increase understanding of sport-related concussion and provide areas for targeted prevention in the future.

Nationwide sports injury prevention strategies: A scoping review

National strategies to prevent sports injuries can potentially improve health outcomes at a population level and reduce medical costs. To date, a compilation of the strategies that countries have attempted, and their effectiveness, does not exist. This scoping review sets out to: identify nationwide attempts at implementing sports injury prevention strategies; examine the impact of these strategies; and map them onto the Translating Research into Injury Prevention Practice (TRIPP) framework. Using Levac's scoping review method, we: (a) identified the research questions, (b) identified relevant studies, (c) identified the study selection criteria, (d) charted the data, and (e) reported the results. A search of MEDLINE, Scopus, SPORTDiscus, CINAHL, and Web of Science databases for articles published pre-June 2019 was conducted. We identified 1794 studies and included 33 studies (of 24 strategies). The USA (n = 7), New Zealand (n = 4), Canada (n = 3), the Netherlands (n = 3), Switzerland (n = 2), Belgium (n = 1), France (n = 1), Ireland (n = 1), South Africa (n = 1), and Sweden (n = 1) have implemented nationwide sports injury prevention strategies with 29 (88%) of the included studies demonstrating positive results. Mapping the strategies onto the TRIPP framework highlighted that only four (17%) of the 24 included strategies reported on the implementation context (TRIPP Stage 5), suggesting an important reporting gap. Nationwide sports injury prevention efforts are complex, requiring a multidimensional approach. Future research should report intervention implementation data; examine the implementation context early in the research process to increase the likelihood of real-world implementation success; and could benefit from incorporating qualitative or mixed research methods.
