Abstract
CONTEXT There is strong evidence that racial and ethnic disparities exist in multiple arenas of health and wellness. The causes of racial and ethnic differences in healthcare are multi- dimensional, one factor that may impact injury/illness communication, interactions, and outcomes is patient-provider racial and ethnic concordance. At present, it is unclear what role patient-provider racial and ethnic concordance and discordance plays in facilitating concussion care for collegiate athletes. OBJECTIVE Investigate the presence of athlete-athletic trainer (AT) racial and ethnic concordance and discordance amongst diagnosed concussion cases, and examine if racial and ethnic concordance and discordance influences time (in days) until diagnosis, symptom resolution, or return-to-sport clinical milestones in collegiate athletes. DESIGN Retrospective cohort study. SETTING Collegiate athletics. PATIENTS OR OTHER PARTICIPANTS A total of 694 concussion cases [38.6% (n=268) sustained by women, 61.4% (n=426) sustained by men] that occurred within the 2015-2016 through 2019- 2020 sport seasons at 9 institutions. MAIN OUTCOME MEASURE(S) The number of days from date of injury to diagnosis, symptom resolution, and return-to-sport; and from date of diagnosis to symptom resolution and return-to- sport. RESULTS Overall, 68.4% (n=475) of concussion cases had patient-provider racial and ethnic concordance and 31.6% (n =219) were discordant. All concordant pairs included a White athlete and White AT. Time to diagnosis differed between the concordant and discordant groups (median[IQR]=1[0,2] versus 0[0,1], respectively) only in the model adjusted for sex, sport-type, and availability of an AT (OR[CI95]=1.46[1.07, 1.85]). There were no other group differences. CONCLUSIONS One-third of concussion cases had athlete-AT racial and ethnic discordance. While this group was diagnosed with a concussion 1-day sooner than the concordant group, no differences were observed for any concussion recovery milestones. These findings suggest that patient-provider racial and ethnic concordance may play a minor role in concussion recognition or reporting, but not necessarily in the management and recovery thereafter.

Describing the appropriate use and interpretation of odds and risk ratios. Res Sports Med 2024; 32:504-510. [PMID: 36217605 DOI: 10.1080/15438627.2022.2132861] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 09/22/2022] [Indexed: 10/17/2022]
Abstract
In sport medicine, epidemiology of sport-related injury provides the foundation for understanding what types of injuries and illnesses occur and who is at the highest risk. Thus, accurate and transparent reporting and interpretation of risk metrics is essential to sports epidemiology. Odds ratios (OR) and risk ratios (RR) are two statistics used to quantify the association between exposure and outcome and are frequently seen in sports medicine literature. While similarities exist, there are optimal ways to use and interpret OR and RR based on the study design and outcome incidence in the target population. In this short communication, we will present common study designs (e.g. prospective cohort, case-control, cross-sectional) along with recommendations for the use and interpretation of OR and RR. This will ultimately assist practitioners in choosing and interpreting these frequently confused measures of association and also help journal reviewers better understand the appropriate use of these measures when evaluating a manuscript.

Physical activity and recovery following concussion in collegiate athletes: a LIMBIC MATARS Consortium Investigation. Brain Inj 2024:1-8. [PMID: 38324635 DOI: 10.1080/02699052.2024.2310791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 01/23/2024] [Indexed: 02/09/2024]
Abstract
OBJECTIVE To investigate whether routine daily activities (RDA), non-prescribed exercise (Non-ERx), or prescribed exercise (ERx) were associated with recovery from sport-related concussion (SRC) in collegiate athletes. MATERIALS AND METHODS Data for this cross-sectional, retrospective chart review of collegiate athletes diagnosed with SRC (n = 285[39.6% female], age = 19.5 ± 1.4 years) were collected during the 2015-16 to 2019-20 athletic seasons. The independent variable was group (RDA, Non-ERx, ERx). Dependent variables included days from date of diagnosis to symptom resolution (Dx-SR) and SR to return to sport (SR-RTS). RESULTS Those in the Non-ERx group took nearly 1.3 times longer to achieve SR (IRR = 1.28, 95% CI: 1.11, 1.46) and, 1.8 times longer for RTS (IRR = 1.82, 95% CI: 1.11, 2.71) when compared to those in the RDA group. No other comparisons were significant. CONCLUSION Collegiate athletes in the Non-ERx group took approximately 1 week longer to achieve SR as compared to the RDA and ERx groups. Our findings suggest that if exercise is recommended following SRC, it must be clearly and specifically prescribed. If exercise parameters cannot be prescribed, or monitored, RDA appear to be similarly beneficial during recovery for collegiate athletes with concussion.

Abstract
Non-disclosed sport-related concussion symptoms pose a significant risk to athletes' health and well-being. Many research investigations have focused on understanding the factors impacting athletes' concussion disclosure behaviors. One of the most robust predictors of the likelihood that an athlete will disclose concussion symptoms to their coaches, athletic trainers, parents, or peers is what researchers term "social norms." The extant literature regarding social norms influencing concussion disclosure behaviors is inconsistent on how the construct should be defined, conceptualized, or measured, often failing to distinguish between descriptive and injunctive social norms and their sources (direct and indirect). In this Technical Report, we provide an overview of these critical distinctions, their importance in assessments, and examples from the literature where scholars have correctly operationalized these constructs in athletic populations. We conclude with a brief set of suggestions for researchers seeking to measure social norms in future research.

Association Between Hospital Participation in Value-Based Programs and Timely Initiation of Post-Acute Home Health Care, Functional Recovery, and Hospital Readmission After Joint Replacement. Phys Ther 2023; 103:pzad123.

Abstract
OBJECTIVES This study examined the association between hospital participation in Bundled Payments for Care Improvement (BPCI) or Comprehensive Care for Joint Replacement (CJR) and the timely initiation of home health rehabilitation services for lower extremity joint replacements. Furthermore, this study examined the association between the timely initiation of home health rehabilitation services with improvement in self-care, mobility, and 90-day hospital readmission. METHOD This retrospective cohort study used Medicare inpatient claims and home health assessment data from 2016 to 2017 for older adults discharged to home with home health following hospitalization after joint replacement. Multilevel multivariate logistic regression was used to examine the association between hospital participation in BPCI or CJR programs and timely initiation of home health rehabilitation service. A 2-staged generalized boosted model was used to examine the association between delay in home health initiation and improvement in self-care, mobility, and 90-day risk-adjusted hospital readmission. RESULTS Compared with patients discharged from hospitals that did not have BPCI or CJR, patients discharged from hospitals with these programs had a lower likelihood of delayed initiation of home health rehabilitation services for both knees and hip replacement. Using propensity scores as the inverse probability of treatment weights, delay in the initiation of home health rehabilitation services was associated with lower improvement in self-care (odds ratio [OR] = 1.23; 95% CI = 1.20-1.26), mobility (OR = 1.15; 95% CI = 1.13-1.18), and higher rate of 90-day hospital readmission (OR = 1.19; 95% CI = 1.15-1.24) for knee replacement. Likewise, delayed initiation of home health rehabilitation services was associated with lower improvement in self-care (OR = 1.16; 95% CI = 1.13-1.20) and mobility (OR = 1.26; 95% CI = 1.22-1.30) for hip replacement. CONCLUSION Hospital participation in BPCI or comprehensive CJR was associated with early home health rehabilitation care initiation, which was further associated with significant increases in functional recovery and lower risks of hospital readmission. IMPACT Policy makers may consider incentivizing health care providers to initiate early home health services and care coordination in value-based payment models.

Cross-sectional study of the association of social relationship resources with Staphylococcus aureus colonization in naturally occurring social groups along the US/Mexico border. PLoS One 2023; 18:e0284400. [PMID: 37053196 PMCID: PMC10101449 DOI: 10.1371/journal.pone.0284400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Accepted: 03/29/2023] [Indexed: 04/14/2023] Open
Abstract
Asymptomatic carriage of Staphylococcus aureus is a major risk factor for subsequent clinical infection. Diminishing returns from mitigation efforts emphasize the need to better understand colonization, spread, and transmission of this opportunistic pathogen. While contact with other people presents opportunities for pathogen exposure and transmission, diversity of social connections may be protective against pathogens such as the common cold. This study examined whether social relationship resources, including the amount and diversity of social contacts, are associated with S. aureus colonization. Participants were community members (N = 443; 68% Hispanic) in naturally occurring social groups in southwestern Arizona. Four types of social relationships and loneliness were assessed, and samples from the skin, nose and throat were obtained to ascertain S. aureus colonization. Overall S. aureus prevalence was 64.8%. Neither the amount nor the diversity of social contacts were associated with S. aureus colonization. The concurrent validity of the social relationship assessments was supported by their moderate intercorrelations and by their positive association with self-rated health. The results suggest that the association of social network diversity and susceptibility to the common cold does not extend to S. aureus colonization. Conversely, colonization prevalence was not higher among those with more social contacts. The latter pattern suggests that social transmission may be relatively infrequent or that more intimate forms of social interaction may drive transmission and colonization resulting in high community prevalence of S. aureus colonization. These data inform communicable disease control efforts.

Abstract
As one of the Research Centers for Minority Institutions (RCMI), the Southwest Health Equity Research Collaborative (SHERC) worked over the first five-year period of funding to foster the advancement of Early Stage Investigators, enhance the quality of health disparities research, and increase institution research capacity in basic Biomedical, Behavioral, and/or Clinical research; all priorities of RCMIs. In year 4, the Technical Assistance Group-Service Center (TAG-SC) was created to help achieve these goals. The TAG-SC provides one-on-one investigator project development support, including research design, data capture, and analysis. Successful implementation of the TAG-SC was tracked using Research Electronic Data Capture (REDCap), a secure, web-based software platform allowing for immediate tracking and evaluation processes. In the first two years, 86 tickets were submitted through the REDCap system for methodological support by TAG-SC experts (faculty and staff) for assistance with health-equity related research, primarily SHERC and externally funded Social/Behavioral research projects. The TAG-SC increased the research capacity for investigators, especially within the SHERC. In this manuscript, we describe the methods used to create the TAG-SC and the REDCap tracking system and lessons learned, which can help other RCMIs interested in creating a similar service center offering an innovative way to build methodological infrastructure.

Abstract
Background The Canada Games are a national level competition held every two years alternating between Summer and Winter Games. Participation in elite level athletics, like the Canada Games, have an inherent risk of injury and illness. Purpose To analyze the incidence and characteristics of injuries and illnesses during Canada Games competitions from 2009-2019 (primarily) and to understand sex differences in odds of musculoskeletal injury for Summer and Winter Canada Games athletes (secondarily). Study Design Descriptive Epidemiology Study. Methods Using a retrospective cohort, data were abstracted from medical incident reports generated during Canada Games from 2009 - 2019. Data were coded for body part injured and injury type or illness system; injuries were also categorized as acute or chronic. Results Across all 10 years of competition, 3160 injuries reported in 8710 male athletes and 3272 injuries reported in 8391 female athletes. Injury incidence was 362.8 and 389.9 and illness incidence was 47.8 and 64.5 per 1000 male and female athletes, respectively. Female athletes had a 1.12 (95% CI: 1.06; 1.19) greater odds of injury and 1.37 (95% CI: 1.20; 1.57) greater odds of illness compared to male athletes. Overall, injury (399.31 vs. 360.31; p < 0.001) and illness (68.67 vs. 47.30; p < 0.001) incidences were higher in Winter Games, compared to Summer Games, per 1000 athletes. When comparing male and female athletes participating in similar sports, sex specific differences exist in odds of both injury and illness. Conclusions Male and female athletes competing in Canada Games competitions demonstrate differences in injury and illness incidence and odds of injury. This suggests a need to examine if additional modifiable risk factors may exist, which could contribute to prevention strategies to reduce injury and illness during Canada Games competition. Level of Evidence 3.

Abstract
ABSTRACT
Disease control relies on pathogen identification and understanding reservoirs. Staphylococcus aureus infection prevention is based upon decades of research on colonization and infection, but diminishing returns from mitigation efforts suggest significant knowledge gaps. Existing knowledge and mitigation protocols are founded upon culture-based detection, with almost no information about pathogen quantities. We employed a qPCR assay on samples from three body sites to characterize colonization more comprehensively than previous studies by describing both prevalence and pathogen quantity. We show a much higher overall prevalence (65.9%) than previously documented, with higher quantities and prevalence associated with the nares, non-Hispanic males (86.9%), and correlating with colonization in other body sites. These results suggest that research and clinical practices likely misclassify over half of colonized persons, limiting mitigation measures and their impact. This work begins the process of rebuilding foundational knowledge of S. aureus carriage with more accurate and wholistic approaches.

Abstract
CONTEXT Athletic training is a multifaceted profession characterized by interpersonal relationships and a team approach to care. Collaborative relationships, by nature, open the door to conflict, which has been reported frequently in the collegiate athletic setting. However, secondary school athletic trainers' (ATs') experiences with conflict and pressure in their role are not readily understood. OBJECTIVE To measure the extent and sources of stress, pressure, and conflict within the secondary school athletic training setting and determine if differences exist across employment characteristics. DESIGN Cross-sectional study. SETTING Secondary school athletics. PATIENTS OR OTHER PARTICIPANTS Secondary school ATs (n = 725, age = 39.8 ± 10.5 years, years certified = 16.7 ± 9.7, years in current role = 10.6 ± 7.8). MAIN OUTCOME MEASURES Participants were asked to reply to an online questionnaire with quantitative measures pertaining to organizational conflict and workplace dynamic. Employment type (school district employee, school district teacher, medical or university facility, independent contractor) and status (full time, part time) served as independent variables. Likert-scale scores (1 = strongly agree to 5 = strongly disagree; 1 = always to 5 = never) and perceived sources of stress, pressure, and conflict were the dependent variables. Analyses consisted of Kruskal-Wallis tests with Mann-Whitney U post hoc tests and odds ratios to assess associations between variables of interest. RESULTS We obtained a 15.3% response rate (725/4745). Although the ATs reported experiencing conflict and pressure, these experiences were relatively infrequent and not universal. Compared with part-time ATs, full-time ATs described higher ratings of strong relationships with coaches (P = .003) and principals (P = .002). The most frequently identified sources of conflict were parents (59%) and coaches (53.9%), followed by athletes (32.6%). Full-time ATs were 1.6 times more likely to report experiencing conflict with a coach than part-time ATs (odds ratio = 1.550, 95% CI = 1.037, 2.317; P = .040). CONCLUSIONS Secondary school ATs' experiences regarding organizational conflict were relatively positive. Instances of pressure and conflict were noted, though relatively infrequently, and these experiences were largely uninfluenced by employment type.

Abstract
Despite vast evidence supporting the effectiveness of lower extremity injury prevention programs in a variety of sport settings, age groups, and levels of competition, there is limited evidence on implementation strategies that positively impact the feasibility, scale-up and sustainability of such programs. Sport-related injury prevention is affected by the research-to-practice gap, a pervasive issue in healthcare, where high-quality experimental research is not used in routine clinical practice. An intervention shown to be efficacious in a controlled environment, such as a lab or in a field-study conducted by scientists, will demonstrate a decline in benefit when implemented in the intended clinical setting. Real-world considerations, such as foundational knowledge and training, time constraints, or end user motivation, influence the quality and consistency of implementation. Acknowledging and addressing implementation barriers in a systematic way is essential to promote effective program dissemination. Study design methods that measure both clinical effectiveness and implementation strategies need to be identified. Hybrid effectiveness-implementation designs simultaneously measure both an intervention's effect on clinical outcomes as well as critical information related to implementation strategy; however these study designs are not frequently utilized. The purpose of this mini-review is to describe: the basics of hybrid designs, rationale for using hybrid designs, and examples of how these designs could be used in athletic healthcare injury prevention research.

Abstract
Purpose To characterize the relationship between adverse childhood experiences (ACEs) and substance use among people incarcerated in a county jail. Design/methodology/approach A questionnaire was administered to 199 individuals incarcerated in a Southwest county jail as part of a social-epidemiological exploration of converging co-morbidities in incarcerated populations. Among 96 participants with complete ACEs data, the authors determined associations between individual ACEs items and a summative score with methamphetamine (meth), heroin, other opiates, and cocaine use and binge drinking in the 30 days prior to incarceration using logistic regression. Findings People who self-reported use of methamphetamine, heroin, other opiates, or cocaine in the 30 days prior to incarceration had higher average ACEs scores. Methamphetamine use was significantly associated with living with anyone who served time in a correctional facility and with someone trying to make them touch sexually. Opiate use was significantly associated with living with anyone who was depressed, mentally ill, or suicidal; living with anyone who used illegal street drugs or misused prescription medications; and if an adult touched them sexually. Binge drinking was significantly associated with having lived with someone who was a problem drinker or alcoholic. Originality Significant associations between methamphetamine use and opiate use and specific adverse childhood experiences suggest important entry points for improving jail and community programming. Social Implications Our findings point to a need for research to understand differences between methamphetamine use and opiate use in relation to particular adverse experiences during childhood, and a need for tailored intervention for people incarcerated in jail.

Abstract
The dynamics of American youth football make it critical to ensure that helmets are appropriately fit to decrease the risk of injuries. Currently, there is only one researcher-developed checklist to determine helmet fit, and psychometric testing is lacking; therefore, the aim of this work was to determine the validity of the checklist. The 13-item checklist was used to measure helmet fit in 267 youth football players prior to the start of the season. Using a Principal Components Analysis to assess validity, a 5-component model was found explaining 58% of the available variance. These results suggest that a single, summative score should not be used for this checklist; rather five scores should be calculated for each component (stability, snugness, size, integrity, and accessory). A more practical and valid tool to assess fit, such as a sub-sectioned chronological American football-specific checklist, can better assist coaches/administrators responsible for helmet fit and player safety.

Abstract
We aimed to estimate the prevalence of cardiovascular risk factors, including hypertension, diabetes, high cholesterol, cigarette smoking, alcohol consumption, and obesity among a sample of individuals incarcerated in an Arizona county jail and compare prevalence estimates to a matched non-institutionalized population. From 2017–2018, individuals housed at a county jail completed a cross-sectional health survey. We estimated the prevalence of hypertension, diabetes, cholesterol, overweight/obesity, cigarette smoking, binge drinking, and self-reported health among individuals incarcerated. We compared prevalence estimates of cardiovascular risk factors to a matched sample of 2017–2018 NHANES participants. Overall, 35.9%, 7.7%, and 17.8% of individuals incarcerated in jail self-reported hypertension, diabetes, and high cholesterol, respectively. Of individuals incarcerated, 59.6% were overweight or obese and 36.8% self-reported fair or poor general health. Over half of individuals incarcerated reported ever smoking cigarettes (72.3%) and binge drinking (60.7%). Compared to a matched sample of NHANES participants, individuals incarcerated in jail had a statistically higher prevalence of cigarette smoking and binge drinking. Screening of cardiovascular risk factors and providing preventive measures and interventions, such as healthy eating, physical activity, or pharmacological adherence interventions, while individuals are incarcerated may contribute to the prevention and management of cardiovascular risk factors and, eventually, cardiovascular disease.

Abstract
BACKGROUND Sports-related concussions are prevalent in the United States. Various diagnostic tools are utilized in order to monitor deviations from baseline in memory, reaction time, symptoms, and balance. Evidence indicates that dehydration may also alter the results of diagnostic tests. PURPOSE The purpose was to determine the effect of exercise-induced dehydration on performance related to concussion examination tools. STUDY DESIGN Repeated measures design. METHODS Seventeen recreationally competitive, non-concussed participants (age: 23.1±3.1 years, height:168.93±10.71 cm, mass: 66.16 ± 6.91 kg) performed three thermoneutral, counterbalanced sessions (rested control, euhydrated, dehydrated). Participants were either restricted (0.0 L/hr) or provided fluids (1.0 L/hr) while treadmill running for 60 min at an intensity equal to 65-70% age-predicted maximum heart rate (APMHR). The Sport Concussion Assessment Tool 3 (SCAT3) was utilized to assess symptoms, memory, balance, and coordination. RESULTS Statistically significant differences were seen among sessions for symptom severity and symptom total. The rested control session had significantly lower values when compared to the dehydrated session. Additionally, the symptom total in the rested control was significantly lower than the euhydrated condition as well. No statistically significant differences were seen for the BESS or memory scores. CONCLUSIONS Mild exercise-induced dehydration results in increased self-reported symptoms associated with concussions. Clinicians tasked with monitoring and accurately diagnosing head trauma should take factors such as hydration status into account when assessing patients for concussion with the SCAT3. Clinicians should proceed with caution and not assume concussion as primary cause for symptom change. LEVEL OF EVIDENCE Level 3.

Reliability of the Tuck Jump Assessment Using Standardized Rater Training. Int J Sports Phys Ther 2021; 16:162-168. [PMID: 33604146 PMCID: PMC7872439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Accepted: 05/24/2020] [Indexed: 11/11/2023] Open
Abstract
BACKGROUND The Tuck Jump Assessment (TJA) is a test used to assess technique flaws during a 10-second, high intensity, jumping bout. Although the TJA has broad clinical applicability, there is no standardized training to maximize the TJA measurement properties. HYPOTHESIS/PURPOSE To determine the reliability of the TJA using varied healthcare professionals following an online standardized training program. The authors hypothesized that the total score will have moderate to excellent levels of intra- and interrater reliability. STUDY DESIGN Cross-sectional reliability. METHODS A website was created by a physical therapist (PT) with videos, written descriptors of the 10 TJA technique flaws, and examples of what constituted no flaw, minor flaw, or major flaw (0,1,2) using published standards. The website was then validated (both face and content) by four experts. Three raters of different professions: a PT, an AT, and a Strength and Conditioning Coach Certified (SCCC) were selected due to their expertise with injury and movement. Raters used the online standardized training, scored 41 videos of participants' TJAs, then scored them again two weeks later. Reliability estimates were determined using intraclass correlation coefficients (ICCs) for total scores of 10 technique flaws and Krippendorff α (K α) for the individual technique flaws (ordinal). RESULTS Eleven of 50 individual technique flaws were above the acceptable level (K α = 0.80). The total score had moderate interrater reliability in both sessions (Session 1: ICC2,2 = 0.64; 95% CI (Confidence Interval) (0.34-0.81); Standard Error Measurement (SEM) = 0.66 technique flaws and Session 2: ICC2,2 = 0.56; 95% CI (0.04-0.79); SEM = 1.30). Rater 1had a good reliability (ICC2,2 = 0.76; 95% CI (0.54-0.87); SEM = 0.26), rater 2 had a moderate reliability (ICC2,2 = 0.62; 95% CI (0.24-0.80); SEM =0.41) and rater 3 had excellent reliability (ICC2,2 = 0.98; 95% CI (0.97-0.99); SEM =0.01). CONCLUSION All raters had at least good reliability estimates for the total score. The same level of consistency was not seen when evaluating each technique flaw. These findings suggest that the total score may not be as accurate when compared to individual technique flaws and should be used with caution. LEVEL OF EVIDENCE 3b.

Abstract
CONTEXT In the event of an acute cardiac event, on-field equipment removal is suggested, although it remains unknown how lacrosse equipment removal may alter time to first chest compression and time to first AED shock. OBJECTIVE To determine time to first chest compression and first AED shock in 2 chest exposure procedures with 2 different pad types. DESIGN Crossover study Setting: Simulation laboratory Participants: Thirty-six athletic trainers (21 females, 15 males; age=30.58±7.81) Main Outcome Measures: Participants worked in pairs to provide 2 rescuer CPR intervention on a simulation manikin (QCPR manikin, Laerdal Medical, Wappingers Falls, NY) outfitted with lacrosse pads and helmet. Participants completed a total of 8 trials per pair (2 chest exposure procedures X 2 pad types X 2 participant roles). The dependent variables were time to first compression (s) and time to first AED shock (s). The independent variables were chest exposure procedure with 2 levels (procedure 1: removal of helmet while initiating CPR over the pads followed by pad retraction and AED application; procedure 2: removal of helmet and removal of pads followed by CPR and AED application) and pad type (Warrior Burn Hitman shoulder pads; Warrior Nemesis chest protector). RESULTS We found a statistically significant interaction between chest exposure procedure and pad type for time to first compression (F1,35=4.66, P=0.04, ω2p=0.10) with significantly faster times during procedure 1 for both the Nemesis pads (16.1±3.4 s) and the Hitman pads (16.1±4.5 s) compared to procedure 2 (Nemesis pads: 49.6±12.9 s, P<0.0001; Hitman pads: 53.8±14.5 s, P<0.0001). CONCLUSIONS Completing the initial cycle of chest compressions over either shoulder pads or a chest protector hastens time to first chest compression without diminishing CPR quality which may improve patient outcomes. Time to first AED shock was not different between equipment procedure or pad type.

Abstract
Recently, protective headgear has been released for women's lacrosse despite the fact that contact to the head is illegal. The purposes of this study were to (1) compare the linear and rotational impact attenuation properties of 2 brands of lacrosse headgear at 4 different locations during laboratory pendulum impacts and (2) determine impact dissipation of new and used lacrosse headgear. We measured peak rotational acceleration (PRA; rad/s2) and linear acceleration (PLA; g) at 4 impact locations (side, rear boss non-centric (NC), front boss, and front) in two headgear brands (Cascade LX, Hummingbird). Two headgear service lives (new headgear, used headgear) were included for the second analysis. During the slower speed, there was a significant interaction between impact location and helmet brand (p = 0.002) for PLA. No other findings were significant. While the Hummingbird headgear reduced linear and rotational accelerations of the headform better than the Cascade headgear during slow velocity impacts to the front and front boss locations, it did so due to extreme motion of the helmet upon impact that we believe may compromise protection of the head and face from lacerations and other injuries.

Abstract
BACKGROUND Understanding concussed athletes' motivations for reporting concussion symptoms is important for health care professionals who are charged with the care, management, and prevention of future injury. OBJECTIVES To examine if athletic and academic identity predict concussion symptom reporting intentions above and beyond traditional socio-cognitive predictors. DESIGN Cross-sectional study using self-report measures during the 2016 collegiate football season. METHOD In a sample of National Collegiate Athletic Association (NCAA) Division I American football athletes (N = 205) we examined the relationship of athletic and academic identity with three indices of symptom reporting behavior: reporting during a game, reporting 24 h after a game, and reporting on behalf of a teammate. We used descriptive statistical analyses, correlations, and linear regression to examine hypotheses. RESULTS Controlling for traditional predictors, athletic identity was associated with a lower likelihood to report symptoms during a game (β = -0.22, t = -3.28, p < .001) or within 24 h (β = -0.28, t = -4.12, p < .001). Academic identity was positively associated with reporting intentions during a game (β = 0.12, t = 1.68, p < .05), 24 h later (β = 0.13, t = 1.85, p < .05), and on behalf of a teammate (β = 0.22, t = -3.36, p < .001). CONCLUSIONS Athletic and academic identities offer additional insight into athletes' motivation for concussion symptom reporting intentions, above and beyond traditional socio-cognitive predictors. Discussion focuses on the benefit of incorporating these important self-identities into educational health interventions to improve their impact.

Abstract
The Cumberland Ankle Instability Tool (CAIT) is used to classify individuals as ankle sprain copers, or as one suffering from chronic ankle instability (CAI). However, literature examining factors contributing to these classifications on the CAIT is lacking, as the CAIT itself does not offer explanations for specific anthropometric measures that influence a patient's classification. Therefore, the purpose was to determine if there was a difference between dorsiflexion active range of motion (AROM) between copers, those with CAI, and a healthy control group. Twenty-two individuals with recent ankle sprains were recruited by a convenience sampling method and placed in the coper (5 females, 5 males, age: 21.9 ± 1.5 years, height: 173.74 ± 7.69 cm, weight: 69.75 ± 10.50 kg) or CAI (10 females, 2 males, age: 21.8 ± 2.3 years, height: 173.99 ± 10.86 cm, weight: 68.14 ± 10.63 kg) groups. The remaining 10 individuals (4 females, 6 males, age: 23.2 ± 1.5 years, height: 178.05 ± 12.92 cm, weight: 75.65 ± 8.00 kg) who participated in the study served as control, as they had never sustained a previous ankle sprain. Dorsiflexion AROM measurements were evaluated using an inclinometer during a weight-bearing lunge. Three measurements were taken for each participant and used for statistical analysis. There was no statistically significant difference in average dorsiflexion AROM between the coper, control, and CAI groups (F2,29 = 2.063, p = 0.15, ω = 0.06, 1 - β = 0.40). Further research is needed to determine if limited dorsiflexion AROM is indeed a contributing factor to an individual's classification as a coper or suffering from CAI, as defined by the CAIT.

Abstract
While research on sport-related concussion has increased dramatically over the past decade, research investigating concussion reporting is in its early stages. The purpose of this project was to assess concussion reporting and work with stakeholders to develop and assess strategies to improve reporting. We used a multi-site, repeated measures design with three NCAA Division I football programs, including 223 athlete participants. A modified community-based participatory research (CBPR) approach was used to develop intervention strategies (Fall 2017 season) with stakeholders designed to increase concussion reporting intentions. Preseason and postseason surveys were administered to determine effectiveness. Main outcome measures included concussion knowledge, intervention effectiveness, and reporting intention measures. For all three programs, concussion knowledge was unrelated to reporting intentions. Two of the three programs implemented the intervention strategies and for these programs there was evidence that the interventions were effective. Specifically, athletes from these two programs perceived more support from coaches about reporting (P< 0.05; t= 2.83), received education more frequently (P< 0.05; t= 2.67), and reported being more likely to report concussion symptoms (P< 0.05; t= 2.14). Our study demonstrates that working with stakeholders to develop site-specific strategies to improve concussion reporting is an effective approach to help improve reporting behaviours.

Abstract
CONTEXT Few researchers have examined the views of important stakeholders in football student-athletes' spheres of influence and whether their views map well in a systems approach to understanding concussion-reporting behavior (CRB). OBJECTIVE To examine the extent to which stakeholders' beliefs about what influences football players' CRBs reflect system-level influences that go beyond individual-level factors. DESIGN Qualitative study. SETTING Four National Collegiate Athletic Association Division I university athletic programs. PATIENTS OR OTHER PARTICIPANTS A total of 26 individuals (athletic directors = 5, athletic trainers [ATs] = 10, football coaches = 11). DATA COLLECTION AND ANALYSIS Semistructured interviews with stakeholders were transcribed and analyzed using the socioecological model according to the Miles and Huberman coding methods. RESULTS Stakeholders largely identified individual-level factors (attitudes), followed by exosystem-level factors (university policies and support for ATs), with fewer microsystem- and mesosystem-level factors (coach influence and communication between coaches and ATs, respectively) and almost no macrosystem-level factors (media influence, cultural norms about aggression and toughness in football). CONCLUSIONS Promising evidence indicates growing stakeholder awareness of the importance of exosystem-level factors (eg, medical personnel and CRB policies) in influencing CRB rates. However, frontline stakeholders and policy makers may benefit from practices that bridge these influences (eg, coach involvement and communication), allowing for a more integrated approach to influence student-athletes' willingness to improve their CRBs.

A Simple Field-Based Tool to Assess Concussion Symptom Reporting Behavior. Am J Prev Med 2019; 56:323-330.

Abstract
INTRODUCTION Prevention and treatment of sport-related concussions is an important public health issue and has led to increased research on concussion symptom reporting behavior. To date, there is neither a common understanding of what constitutes concussion symptom reporting behavior nor measures that capture key features of concussion symptom reporting behavior. Concussion symptom reporting behavior can be initiated by an athlete, an athletic trainer, coach, or teammate and can occur in competition, practice, or days after symptoms appear. Follow-up diagnostics range from asking athletes initial questions about their symptoms to conducting rapid standardized sideline assessments to conducting full comprehensive concussion screens. Currently, for athletes who are not formally diagnosed with concussion, no information about concussion symptom reporting behavior sources, screening methods, or context is collected. METHODS Pilot data were collected from four National Collegiate Athletic Association Division I football programs. Athletic trainers recorded data about key concussion symptom reporting behavior features during the 2016 and 2017 football seasons. The 2016 data were analyzed in Spring 2017 and the reporting form was adapted for the Fall 2017 season. Two programs completed records during the 2017 season. These records were analyzed in Spring 2018. RESULTS Concussion symptom reporting behavior is most often initiated by athletes in practice contexts, followed by athletic trainers in game contexts. The 2017 data revealed that, regardless of source, 45% of initial screens received a comprehensive screen and about 25% of comprehensive screens originated by athlete or athletic trainer concussion symptom reporting behavior resulted in concussion diagnosis. Results led to development of a brief concussion symptom reporting behavior recording tool that can be used in practice, game, and athletic training room settings. CONCLUSIONS The smartphone-supported Concussion Symptom Reporting Tool provides a rapid and easy way to record concussion symptom reporting behavior as well as estimate program-specific data for stakeholders interested in understanding concussion symptom reporting behavior.

Abstract
OBJECTIVE To describe the concept of statistical power as related to comparative interventions and how various factors, including sample size, affect statistical power. BACKGROUND Having a sufficiently sized sample for a study is necessary for an investigation to demonstrate that an effective treatment is statistically superior. Many researchers fail to conduct and report a priori sample-size estimates, which then makes it difficult to interpret nonsignificant results and causes the clinician to question the planning of the research design. DESCRIPTION Statistical power is the probability of statistically detecting a treatment effect when one truly exists. The α level, a measure of differences between groups, the variability of the data, and the sample size all affect statistical power. RECOMMENDATIONS Authors should conduct and provide the results of a priori sample-size estimations in the literature. This will assist clinicians in determining whether the lack of a statistically significant treatment effect is due to an underpowered study or to a treatment's actually having no effect.

Abstract
The Functional Movement Screen (FMS) is a popular movement screen used by rehabilitation, as well as strength and conditioning, professionals. The FMS, like other movement screens, identifies movement dysfunction in those at risk of, but not currently experiencing, signs or symptoms of a musculoskeletal injury. Seven movement patterns comprise the FMS, which was designed to screen fundamental movement requiring a balance between stability and mobility. The 7 movement patterns are summed to a composite FMS score. For an instrument to have wide applicability and acceptability, there must be high levels of reliability, validity, and accuracy. The FMS is certainly a reliable tool, and can be consistently scored within and between raters. Although the FMS has high face and content validity, the criterion validity (discriminant and convergent) is low. Additionally, the FMS does not appear to be studying a single construct, challenging the use of the summed composite FMS score. The accuracy of the FMS in screening for injury is also suspect, with low sensitivity in almost all studies, although specificity is higher. Finally, within the FMS literature, the concepts of prediction and association are conflated, combined with flawed cohort studies, leading to questions about the efficacy of the FMS to screen for injury. Future research on the use of the FMS, either the composite score or the individual movement patterns, to screen for injury or injury risk in adequately powered, well-designed studies are required to determine if the FMS is appropriate for use as a movement screen.

Abstract
BACKGROUND A reliable measure of dynamic postural control is needed for inclusion in the sports-related concussion assessment battery. Currently, there is not a clinical gold standard. The Limits of Stability (LOS) test has potential to be a useful tool to collect objective data on important dynamic postural stability variables. Psychometric properties of the LOS test with healthy young adults are yet to be established. HYPOTHESIS/PURPOSE The purpose of this study was to examine the intra-session and test-retest reliability for the LOS on the NeuroCom® VSR Sport when performed by young adults. STUDY DESIGN Reliability study. METHODS Twenty-seven healthy university students completed four trials of the LOS in each of two testing sessions one week apart. Relative reliability was measured within each session with an intraclass correlation coefficient (ICC[3,k]) for Session 1 and Session 2, respectively, on each of the five dependent variables (movement velocity [MVL], directional control [DCL], maximum excursion [MXE], endpoint excursion [EPE], and reaction time [RT]) provided by the Neurocom. Test-retest reliability was assessed using a repeated-measures analysis of variance along with an ICC (3,k) for relative reliability. An ICC value of 0.90 or higher was defined as having a high reliability, moderate reliability for ICC values between 0.80-0.89, and below 0.80 as questionable. RESULTS The reliability within each session for LOS composite scores for MVL, DCL, and MXE was moderate to high (ICC[3,k]=0.89-0.95). These same three variables also had high levels of test-retest reliability (ICC[3,k]=0.95-0.96). EPE and RT had moderate reliability over time (ICC[3,k]=0.88) but differences for within session reliability. CONCLUSIONS LOS provides a reliable measure of dynamic postural control for young adults. Two trials are recommended at baseline with the first being an adaptation trial to ensure accuracy of findings. Care needs to be taken when interpreting EPE and DCL scores on post-injury tests due to a learning effect for those variables. LEVEL OF EVIDENCE 2c.

Abstract
CONTEXT Patient ventilation volume and rate have been found to be compromised due to the inability to seal a pocket mask over the chinstrap of football helmets. The effects of supraglottic airway devices such as the King LT and of lacrosse helmets on these measures have not been studied. OBJECTIVE To assess the effects of different airway management devices and helmet conditions on producing quality ventilations while performing cardiopulmonary resuscitation on simulation manikins. DESIGN Crossover study. SETTING Simulation laboratory. PATIENTS OR OTHER PARTICIPANTS Thirty-six athletic trainers (12 men, 24 women) completed this study. INTERVENTION(S) Airway-management device (pocket mask, oral pharyngeal airway, King LT airway [KA]) and helmet condition (no helmet, Cascade helmet, Schutt helmet, Warrior helmet) served as the independent variables. Participant pairs performed 2 minutes of 2-rescuer cardiopulmonary resuscitation under 12 trial conditions. MAIN OUTCOME MEASURE(S) Ventilation volume (mL), ventilation rate (ventilations/min), rating of perceived difficulty (RPD), and percentage of quality ventilations were the dependent variables. RESULTS A significant interaction was found between type of airway-management device and helmet condition on ventilation volume and rate ( F12,408 = 2.902, P < .0001). In addition, a significant interaction was noted between airway-management device and helmet condition on RPD scores ( F6,204 = 3.366, P = .003). The no-helmet condition produced a higher percentage of quality ventilations compared with the helmet conditions ( P ≤ .003). Also, the percentage of quality ventilations differed, and the KA outperformed each of the other devices ( P ≤ .029). CONCLUSIONS The helmet chinstrap inhibited quality ventilation (rate and volume) in airway procedures that required the mask to be sealed on the face. However, the KA allowed quality ventilation in patients wearing a helmet with the chinstrap fastened. If a KA is not available, the helmet may need to be removed to provide quality ventilations.

Abstract
CONTEXT Performance of quality cardiopulmonary resuscitation is essential for improving patient outcomes. Performing compressions over football equipment inhibits compression depth and rate, but lacrosse equipment has not yet been studied. OBJECTIVE To assess the effect of lacrosse shoulder pads on the ability to provide quality chest compressions on simulation manikins. DESIGN Crossover study. SETTING Simulation laboratory. PATIENTS OR OTHER PARTICIPANTS Thirty-six athletic trainers (12 men: age = 33.3 ± 9.7 years; 24 women: age = 33.4 ± 9.8 years). MAIN OUTCOME MEASURE(S) No shoulder pads (NSP), Warrior Burn Hitman shoulder pads (WSP), and STX Cell II shoulder pads (SSP) were investigated. Outcomes were chest-compression depth (millimeters), rate (compressions per minute), rating of perceived exertion (0-10), hand-placement accuracy (%), and chest recoil (%). RESULTS We observed a difference in mean compression depth among shoulder-pad conditions ( F2,213 = 3.73, P = .03, ω2 = 0.03), with a shallower depth during the WSP (54.1 ± 5.8 mm) than the NSP (56.8 ± 5.7 mm; P = .02) trials. However, no differences were found in mean compression rate ( F2,213 = 0.87, P = .42, ω2 = 0.001, 1-β = .20). We noted a difference in rating of perceived exertion scores ( F2,213 = 16.41, P < .001, ω2 = 0.12). Compressions were more difficult during the SSP condition (4.1 ± 1.3) than during the NSP (2.9 ± 1.2; P < .001) and WSP (3.3 ± 1.1; P = .002) conditions. A difference was present in hand-placement accuracy among the 3 shoulder-pad conditions (χ22 = 11.14, P = .004). Hand-placement accuracy was better in the NSP than the SSP condition ( P = .002) and the SSP than the WSP condition ( P = .001). CONCLUSIONS Lacrosse shoulder pads did not inhibit the ability to administer chest compressions with adequate rate and depth. With appropriate training to improve hand placement, the pads may be left in place while cardiopulmonary resuscitation is initiated during sudden cardiac arrest.

Abstract
OBJECTIVE To describe the concepts of measurement reliability and minimal important change. BACKGROUND All measurements have some magnitude of error. Because clinical practice involves measurement, clinicians need to understand measurement reliability. The reliability of an instrument is integral in determining if a change in patient status is meaningful. DESCRIPTION Measurement reliability is the extent to which a test result is consistent and free of error. Three perspectives of reliability-relative reliability, systematic bias, and absolute reliability-are often reported. However, absolute reliability statistics, such as the minimal detectable difference, are most relevant to clinicians because they provide an expected error estimate. The minimal important difference is the smallest change in a treatment outcome that the patient would identify as important. RECOMMENDATIONS Clinicians should use absolute reliability characteristics, preferably the minimal detectable difference, to determine the extent of error around a patient's measurement. The minimal detectable difference, coupled with an appropriately estimated minimal important difference, can assist the practitioner in identifying clinically meaningful changes in patients.

Abstract
CONTEXT The Guardian Cap provides a soft covering intended to mitigate energy transfer to the head during football contact. Yet how well it attenuates impacts remains unknown. OBJECTIVE To evaluate the changes in the Gadd Severity Index (GSI) and linear acceleration during drop tests on helmeted headforms with or without Guardian Caps. DESIGN Crossover study. SETTING Laboratory. PATIENTS OR OTHER PARTICIPANTS Nine new football helmets sent directly from the manufacturer. INTERVENTION(S) We dropped the helmets at 3 velocities on 6 helmet locations (front, side, right front boss, top, rear right boss, and rear) as prescribed by the National Operating Committee on Standards for Athletic Equipment. Helmets were tested with facemasks in place but no Guardian Cap and then retested with the facemasks in place and the Guardian Cap affixed. MAIN OUTCOME MEASURE(S) The GSI scores and linear accelerations measured in g forces. RESULTS For the GSI, we found a significant interaction among drop location, Guardian Cap presence, and helmet brand at the high velocity (F10,50 = 3.01, P = .005) but not at the low (F3.23,16.15 = 0.84, P = .50) or medium (F10,50 = 1.29, P = .26) velocities. Similarly for linear accelerations, we found a significant interaction among drop location, Guardian Cap presence, and helmet brand at the high velocity (F10,50 = 3.01, P = .002, ω2 = 0.05) but not at the low (F10,50 = 0.49, P = .89, ω2 < 0.01, 1-β = 0.16) or medium (F5.20,26.01 = 2.43, P = .06, ω2 < 0.01, 1-β = 0.68) velocities. CONCLUSIONS The Guardian Cap failed to significantly improve the helmets' ability to mitigate impact forces at most locations. Limited evidence indicates how a reduction in GSI would provide clinically relevant benefits beyond reducing the risk of skull fracture or a similar catastrophic event.

Abstract
Timely and appropriate rehabilitation of musculoskeletal injuries is the most effective way of restoring full function and decreasing the likelihood of recurrence of the same injury. Application of specific physical therapy modalities and therapeutic exercises is based on the stages of healing. A typical physical therapy protocol progresses sequentially through the following phases: pain control, restoring range of motion, restoring strength, neuromuscular retraining, and return to full activity. The commonly used modalities reviewed here include heat, cold, ultrasound, phonophoresis, iontophoresis, and electrical stimulation. In this article we provide a basic review of physical therapy modalities.
