Efforts to Improve Diversity, Equality, and Inclusion in Sports Medicine via Community Engagement Initiatives Within American Cities Divided by Racial, Social, and Economic Factors.

Although the twenty-first century has seen major advances in evidence-based medicine to improve health, athletic performance, and injury prevention, our inability to implement these best practices across underserved American communities has limited the impact of these breakthroughs in sports medicine. Rochester, NY is stereotypical of American communities in which an economically challenged racially diverse urban center with grossly underperforming public schools is surrounded by adequately resourced predominantly Caucasian state-of-the-art education systems. As these great disparities perpetuate and further degrade our society in the absence of interventions, the need for community engagement initiatives is self-evident.

Focus areas and methodological characteristics of North American-based health disparity research in sports medicine: a scoping review.

OBJECTIVE: Health disparities are widely prevalent; however, little has been done to examine and address their causes and effects in sports and exercise medicine (SEM). We aimed to summarise the focus areas and methodology used for existing North American health disparity research in SEM and to identify gaps in the evidence base. DESIGN: Scoping review. DATA SOURCES: Systematic literature search of PubMed, Scopus, SPORTDiscus, CINAHL Plus with Full Text, Web of Science Core Collection and Cochrane Central Register of Controlled Trials. ELIGIBILITY CRITERIA: Full-text, peer-reviewed manuscripts of primary research, conducted in North America; published in the year 2000 or after, in English; and focusing on organised sports were included. RESULTS: 103 articles met inclusion criteria. Articles were classified into five focus areas: access to and participation in sports (n=45), access to SEM care (n=28), health-related outcomes in SEM (n=24), provider representation in SEM (n=5) and methodology (n=1). Race/ethnicity (n=39), socioeconomic status (n=28) and sex (n=27) were the most studied potential causes of health disparities, whereas sexual orientation (n=5), location (rural/urban/suburban, n=5), education level (n=5), body composition (n=5), gender identity (n=4) and language (n=2) were the least studied. Most articles (n=74) were cross-sectional, conducted on youth (n=55) and originated in the USA (n=90). CONCLUSION: Health disparity research relevant to SEM in North America is limited. The overall volume and breadth of research required to identify patterns in a heterogeneous sports landscape, which can then be used to inform positive change, need expansion. Intentional research focused on assessing the intersectionality, causes and consequences of health disparities in SEM is necessary.

Tarsal Navicular Bone Stress Injuries: A Multicenter Case Series Investigating Clinical Presentation, Diagnostic Approach, Treatment, and Return to Sport in Adolescent Athletes.

BACKGROUND: Tarsal navicular bone stress injuries (BSIs) are considered "high risk" because of prolonged healing times and higher rates of nonunion in adult populations but, to our knowledge, have not been comprehensively examined in adolescent athletes. PURPOSE: To describe the characteristics of tarsal navicular BSIs in adolescents. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A retrospective analysis of patients aged 10 to 19 years with a radiographically diagnosed tarsal navicular BSI was performed at 8 academic centers over a 9-year study period. Age, sex, body mass index (BMI), primary sport, physical examination findings, imaging, treatment, surgical technique, return-to-sport time, and complications were analyzed. RESULTS: Among 110 patients (mean age, 14.7 ± 2.7 years; 65% female), common primary sports were cross-country/track and field (29/92 [32%]) and gymnastics/dance (25/92 [27%]). Grade 4 BSIs were identified in 44% (48/110) of patients, with fracture lines present on radiography or magnetic resonance imaging. Nonoperative treatment (mean age, 14.4 ± 2.6 years), consisting of protected weightbearing and either a protective boot (69/88 [78%]) or a cast (19/88 [22%]), was trialed in all patients and was successful in 94 patients (85%). Operative treatment (mean age, 17.1 ± 1.4 years) was ultimately pursued for 16 patients (15%). Patients who required surgery had a higher BMI and a higher percentage of fracture lines present on imaging (nonoperative: 36/94 [38%]; operative: 14/16 [88%]). The median time to return to weightbearing, running, and full sport was significantly longer in duration for the operative group than the nonoperative group (P <.05). Complications associated with surgery included 1 case each of delayed union, nonunion, and painful implants, the latter of which required secondary surgery. CONCLUSION: Adolescent tarsal navicular BSIs were identified most commonly in female patients in leanness sports. Adolescents who required surgery were more likely to be older, have higher BMIs, and have grade 4 BSIs, and they returned to sport within a median of 5 months after single- or double-screw fixation with a low risk of postoperative complications. A better understanding of the presenting signs and symptoms and appropriate diagnostic imaging of navicular BSIs may lead to an earlier diagnosis and improved outcomes.

Clinical performance of a multiparametric MRI-based post concussive syndrome index.

Introduction: Diffusion Tensor Imaging (DTI) has revealed measurable changes in the brains of patients with persistent post-concussive syndrome (PCS). Because of inconsistent results in univariate DTI metrics among patients with mild traumatic brain injury (mTBI), there is currently no single objective and reliable MRI index for clinical decision-making in patients with PCS. Purpose: This study aimed to evaluate the performance of a newly developed PCS Index (PCSI) derived from machine learning of multiparametric magnetic resonance imaging (MRI) data to classify and differentiate subjects with mTBI and PCS history from those without a history of mTBI. Materials and methods: Data were retrospectively extracted from 139 patients aged between 18 and 60 years with PCS who underwent MRI examinations at 2 weeks to 1-year post-mTBI, as well as from 336 subjects without a history of head trauma. The performance of the PCS Index was assessed by comparing 69 patients with a clinical diagnosis of PCS with 264 control subjects. The PCSI values for patients with PCS were compared based on the mechanism of injury, time interval from injury to MRI examination, sex, history of prior concussion, loss of consciousness, and reported symptoms. Results: Injured patients had a mean PCSI value of 0.57, compared to the control group, which had a mean PCSI value of 0.12 (p = 8.42e-23) with accuracy of 88%, sensitivity of 64%, and specificity of 95%, respectively. No statistically significant differences were found in the PCSI values when comparing the mechanism of injury, sex, or loss of consciousness. Conclusion: The PCSI for individuals aged between 18 and 60 years was able to accurately identify patients with post-concussive injuries from 2 weeks to 1-year post-mTBI and differentiate them from the controls. The results of this study suggest that multiparametric MRI-based PCSI has great potential as an objective clinical tool to support the diagnosis, treatment, and follow-up care of patients with post-concussive syndrome. Further research is required to investigate the replicability of this method using other types of clinical MRI scanners.

Athlete Identity and Mental Health of Student Athletes during COVID-19.

The purpose of our study is to evaluate athletic identity (AI) and mental health measures of youth and young adult athletes during the COVID-19 pandemic. This cross-sectional study recruited athletes aged 11-25 years from universities, high schools, and middle schools in California and New York. Participants were emailed a link to an anonymous, cross-sectional electronic survey. The measure included the athletic identity measurement scale (AIMS), the Patient Health Questionnaire-4 (PHQ-4), and demographic variables. Chi-square, Fisher's Exact Test, and linear regression were used to examine the relationships between AI, symptoms of anxiety, and symptoms of depression by age, gender, and race. The survey was completed by 653 participants. AI was stratified by tertiary percentiles. The odds of positively scoring for symptoms of anxiety were 60% higher for participants in college compared with high school (OR: 1.60, 95% CI: [1.09, 2.35]). Conversely, the odds of scoring positively for symptoms of depression were 68% higher for participants in high school compared to college (OR: 1.68, 95% CI: [1.09, 2.59]). The odds of scoring positively for symptoms of depression were higher for athletes who scored as high AI, compared to those who scored as moderate (OR: 1.72, 95% CI: [1.11, 2.68]) or low (OR: 1.93, 95% CI: [1.20, 3.12]). The odds of scoring positively for symptoms of anxiety on the PHQ-4 were 3.2 times higher for participants who identified as female (OR: 3.19, 95% CI: [2.31, 4.41]), and the odds of scoring positively for symptoms of depression were 2.4 times higher for participants who identified as female (OR: 2.35, 95% CI: [1.56, 3.54]). Female athletes experienced symptoms of depression and anxiety at significantly higher rates than male athletes during the COVID-19 pandemic. High school students experienced fewer symptoms of anxiety, but greater symptoms of depression as compared to the collegiate group, while college students experienced greater odds of symptoms of anxiety. Athletes in the high AI group were more likely to report symptoms of depression than moderate or low identity groups. Female athletes reported lower AI than male athletes, but still had greater symptoms of anxiety and depression.

Stress Injuries of the Knee.

Stress injuries to the bone and physis of the knee are common in the active adolescent patient and can be broken down into bone stress injuries (BSIs) and chronic physeal stress injuries. BSIs result from prolonged, repetitive bone loading, whereas chronic physeal stress injuries develop from repetitive loading to the apophysis or epiphysis. Most stress injuries of the knee resolve with relative rest but will occasionally need surgical intervention in more severe cases. Early and accurate identification is paramount for optimal management and to avoid long-term consequences.

Sports Bra Preferences by Age and Impact of Breast Size on Physical Activity among American Females.

For many females, sports bras are an essential piece of equipment for participation in sports and physical activity. Breast pain or discomfort from lack of support may be a contributing factor to the noted gender disparity in physical activity of females compared to males. Our objective was to evaluate sports bra usage and characterize sports bra preferences of an active female cohort. This multicenter cross-sectional survey study was conducted at five geographically distinct academic centers. Our measure was administered during outpatient sports medicine clinic visits to females aged 11-64 years old. Chi-square tests were used to compare characteristics across subgroups. Our analysis consisted of 438 respondents, with a mean age of 22 ± 12.2 years. More than a quarter (27.4%) reported lack of breast support prevented them from being active or exercising. Age (p = 0.03), breast size (p < 0.0001), and household income (p = 0.01) were significantly associated with greater frequency of physical activity being limited by lack of breast support. Lack of breast support may be an important barrier for young females of specific populations to meeting physical activity recommendations. Further research is needed to improve the understanding of this important piece of sporting equipment for women.

Athletic Identity in Youth Athletes: A Systematic Review of the Literature.

Athletic identity (AI), the degree of personal connection to sport, is well-described in adult research; however, this social trait has been less studied in younger age groups. This systematic review describes epidemiological characteristics of AI in youth athletes. PubMed, Embase and PsycInfo were searched to identify AI studies involving quantitative athlete identity outcomes and cohorts 22 years and younger. The search strategy was developed for each database using the Boolean method. PRISMA guidelines and the Appraisal Tool for Cross-Sectional Studies (AXIS) were utilized. Ten out of ninety-one studies met inclusion criteria. AI scores differed by race/ethnicity. Two studies found increased AI during adolescence compared to later in ones' training. Mental health-focused studies revealed higher AI levels protect against burnout, but in injured athletes, increased depression risk. Transitioning to a higher level of play during adolescence can correlate with stronger senses of AI. Further research should explore the concept of athletic identity saliency as one moves through an athletic career or training program and how thoughts of perceived success, professional progression, recruitment prospect or injury affect levels of athletic identity.

Strategies for Gait Retraining in a Collegiate Runner with Transfemoral Amputation: A Case Report.

BACKGROUND: More than fifty percent of people with limb amputations participate in sports or physical activity following amputation. Athletes with limb amputations may face additional challenges including phantom limb pain (PLP), psychological barriers, prosthetic complications, and gait abnormalities. Prevalence of PLP in the general amputee population is estimated to be as high as 85%. Despite the high prevalence of PLP, there is little research regarding the use of gait training as a treatment for PLP among both the general amputee population and athletes. CASE DESCRIPTION: A 20-year old female collegiate track and field athlete presented with phantom knee pain brought on with running. The athlete demonstrated deficits in core and hip strength as well as decreased single leg stability bilaterally. Running gait analysis revealed circumduction with the prosthesis for limb advancement and increased vaulting with push off on the sound (uninvolved) limb. Gait retraining strategies were implemented to address video analysis findings and create a more efficient running gait and address phantom limb pain symptoms. OUTCOMES: Rehabilitation and gait retraining strategies were effective in improving several clinical and functional outcomes in this case. Significant improvements were noted in PLP, running gait mechanics, and the patient's psychological and functional status as measured with a standardized outcome tool, the Patient-Reported Outcomes Measurement Information System® (PROMIS®). DISCUSSION: Running gait training following amputation could be a crucial component of rehabilitation for athletes in an attempt to lessen pain while running, especially in those experiencing phantom limb pain (PLP). Utilization of a multidisciplinary team in the gait retraining process is recommended. There is a need for further research to determine the effects of running gait retraining for management of PLP in athletes with amputation. LEVEL OF EVIDENCE: 5.

Racial and Ethnic Diversity of Athletic Trainers of the National Collegiate Athletic Association: A Retrospective Study.

CONTEXT: Athletic trainers (ATs) are the most visible members of the sports medicine team and are responsible for the health and well-being of student-athletes (SAs). OBJECTIVE: Quantifying the representation from Black, Indigenous, and People of Color (BIPOC) ATs in National Collegiate Athletic Association (NCAA) member institutions has not been previously studied. DESIGN: Retrospective study Setting: National Collegiate Athletic Association's (NCAA) Demographic Database Participants: NCAA teams' athletic personnel at NCAA member institutions. MAIN MEASURES: Chi-square tests were employed to assess differences in racial and ethnic frequencies across division, calendar year and gender. Linear regressions models were used to examine change in racial and ethnic distributions of head and assistant ATs over time. RESULTS: The majority of NCAA athletic trainers were categorized as white (88%), which was reflected in both head (90.8%) and assistant (87.2%) AT positions. Black ATs made up the largest proportion of a specific racial/ethnicity group within BIPOC ATs (3.4% of head ATs, 4.6% of assistant ATs), with the next most prevalent being Hispanic (2.8% of head ATs, 3.9% of assistant ATs). Historically Black College and Universities (HBCUs) showed higher proportions of BIPOC ATs in both head and assistant categories compared to non-HBCU institutions. Division I schools had the greatest AT racial/ethnicity diversity in comparison to Division II and Division III (p<0.0001). In our linear regression models, we found statistically significant increases in many of the racial/ethnic categories for both head and assistant ATs. CONCLUSIONS: Our study demonstrates that BIPOC ATs represent a small proportion of the ATs currently working at NCAA member institutions. Although there has been an increase in BIPOC athletic trainers over the past ten years, a large racial and ethnic discordance gap still exists between student athletes and the ATs caring for them. Future studies may identify barriers encountered by BIPOC ATs and the effectiveness of current diversity initiatives.

Sports Medicine-Related Breast and Chest Conditions-Update of Current Literature.

ABSTRACT: This article reviews the most up-to-date evidence-based recommendations pertaining to breast and upper chest conditions, specifically for the sports medicine physician. Because of the unique circumstances of the team physician, they can see a wide breadth of pathology. Athletes may not have a primary care physician and may prefer to present to their team physician for breast and upper chest conditions. It is often more comfortable and convenient for athletes to seek treatment in the team setting. Therefore, it is important that the medical professional be aware of not only common pathology but also of that which is rarer. Any delay in evaluation can result in unnecessary morbidity and lead to complications or extended time lost from sport. Consequently, it also is important to facilitate an atmosphere encouraging early presentation and workup.

Track and field injuries resulting in emergency department visits from 2004 to 2015: an analysis of the national electronic injury surveillance system.

OBJECTIVES: Determine national estimates of injuries, mechanisms of injury (MOI), and injury severity among men and women engaging in track and field activities in the United States (U.S.), aged 18 years and older, who present to emergency departments (ED). METHODS: Retrospective analyses of injury narratives were conducted using data from the National Electronic Injury Surveillance System (NEISS) of the Consumer Product Safety Commission (CPSC), comprising individuals 18 and older presenting to U.S. EDs from 2004 to 2015, with injuries associated with track and field, applying the NEISS product code 5030 and patient narratives. National injury estimates were calculated using sample weights. National injury incidence rates were determined using U.S. census estimate data (denominator), and comparisons of categorical variables by gender were made using a chi-squared test, and associated p-values. RESULTS: Estimated 42,947 ED visits among individuals 18 and older presented for track and field-related injuries in the U.S. from 2004 to 2015, consisting of 23,509 incidents among men, and 19,438 among women. The highest rates of injury occurred in 2010 among men, and 2011 among women, with 3.47, and 2.70 injuries per 100,000 U.S. population, respectively. No statistically significant differences (α = 0.05) were found between genders for injury severity (p = 0.32), injury diagnosis (p = 0.30), and body region (p = 0.13), but there was a significant difference overall between genders for mechanism of injury (p = 0.01). CONCLUSIONS: To develop appropriate injury preventive interventions for track and field athletes, additional studies exploring associations between injury characteristics, namely the mechanisms of injury, and gender, are necessary.

Female Athlete and Sports-Related Concussions.

Female athletes are participating in collision sports in greater numbers than previously. The overall incidence of concussion is known to be higher in female athletes than in male athletes participating in similar sports. Evidence suggests anatomic, biomechanical, and biochemical etiologies behind this sex disparity. Future research on female athletes is needed for further guidance on prevention and management of concussion in girls and women.

Use of Fitbit Data to Evaluate the Effects of an Athletic Performance and Injury Prevention Training Program on Daily Physical Levels in Underrepresented Minority Female High School Athletes: A Prospective Study.

A marginal number of adolescents meet the recommended guidelines of 60 minutes of moderate to vigorous daily physical activity, and even fewer underrepresented minority females achieve this metric as compared to their male and white counterparts. While potential interventions exist to address these low levels of activity, which is a known risk for acute injuries and chronic disease, there is lack of consensus on the devices used to measure the intensity of daily activity levels. Wearable activity trackers such as Fitbit™ have been utilized to quantify human motion and exercise intensity, but there is little precedence for these measures being assessed in adolescent wearers. Thus, our objective was to assess the feasibility of using Fitbit to assess daily physical activity levels in underrepresented minority adolescent females, who attend an economically challenged urban high school, over the course of a physical activity intervention. We also aimed to identify candidate Fitbit outcome measures for future prospective studies. A 10-week physical activity intervention was implemented in a cohort of 24 high school female athletes. From within this cohort, a sample of five students were provided Fitbit™ devices, from which we obtained data sets from three students. Activity on the days of the exercise intervention was measured and compared to activity on non-intervention days. Post-hoc assessments were performed based on individual heart rate reserves, the predefined levels set by the Inspire Fitbit™ device and the American College of Sports Medicine (ACSM) 2009 guidelines. The results showed that while compliance is challenging, wearable devices can be used to assess daily physical activity levels and intensities in underrepresented minority high school female athletes during an extended physical activity intervention. Of the Fitbit outcomes currently available, assessment of moderate-vigorous activity (min/day) appeared to be the best as a measure of global physical activity. Prospective research is now warranted to validate these thresholds, and to test novel interventions for their ability to transition inactive adolescents at risk of sports-related injuries and long-term chronic disease, into a more active lifestyle.

Timing and Reasons Behind Single-Sport Specialization in Soccer: A Survey of 64 Major League Soccer Athletes.

BACKGROUND: Single-sport specialization at the exclusion of other sports has become increasingly popular in youth sporting culture. The purpose of this study was to survey Major League Soccer (MLS) athletes to examine factors influencing the timing of single-sport specialization in soccer. HYPOTHESIS: The majority of surveyed athletes will have participated in multiple sports prior to specialization and specialized primarily as a result of a coach's recommendation, with no significant impact on specialization timing stemming from birth or high school location, obtaining a collegiate scholarship, MLS experience, or position. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 4. METHODS: Anonymous surveys were distributed to 3 MLS organizations and completed by MLS athletes during preseason physicals. Surveys evaluated the age and reason(s) behind an athlete's decision to specialize in soccer, birth location, geographic high school location for US-born athletes, participation in a developmental league, college scholarship, years in the MLS, and position played. RESULTS: Approximately 74% (64/86) of athletes returned completed surveys. Athletes reported beginning soccer at a mean age of 5.1 ± 2.1 years and specializing at age 12.6 ± 4.3 years. Athletes who participated in no other sports prior to specialization (P < 0.001), athletes reporting soccer to be their first sport played at an advanced level (P < 0.001), and athletes receiving a college scholarship (P = 0.02) specialized at a significantly younger age. Internationally born athletes specialized at significantly younger ages when compared with US-born athletes (P < 0.001). CONCLUSION: The majority of athletes participated in multiple sports prior to specialization and eventually specialized to focus exclusively on soccer. The timing of sport specialization in professional MLS athletes was not associated with multisport participation prior to specialization, playing soccer at an advanced level prior to other sports, receiving a college scholarship, or being born outside the United States. CLINICAL RELEVANCE: Timing of sport specialization is associated with multiple factors prior to athlete promotion to the MLS that warrant further investigation to better understand the impact of specialization on injury incidence, performance, and career length.
