Autonomy, relationality, and brain-injured athletes: a critical examination of the Concussion in Sport Group’s Consensus Statements between 2001 and 2023

ABSTRACT This article critically examines the development and consensus outputs of the Concussion in Sport Group. We examine the six Consensus Statements between 2001 and 2023 to explore the challenges that the presence of contextual forces pose to the development of effective and ethically justifiable medical guidelines to manage situations involving brain-injured athletes. First, we discuss the implicit and explicit ethical framework and goals underlining the statements. Secondly, drawing on a relational account of athlete choice, we expound on the limitations of the framework, concentrating on those resulting from a simplified understanding of athlete autonomy. Thirdly, we conclude by proposing a series of recommendations to improve concussion management protocols: (1) adopting a broader understanding of autonomy built upon relational accounts, beyond just the healthcare professional-athlete relationship; (2) further minimizing conflicts of interest that increase athletes’ vulnerability and hinder decision-making ability; (3) enhancing healthcare professional training to allow better adjustment of treatment plans to athletes’ contexts; and (4) promoting research on sociocultural elements affecting athletes’ vulnerability and autonomy.

Associations of Sex and Sport Contact-Level with Recovery Timelines Among Collegiate Athletes with Sport-Related Concussion

BackgroundGrowing interest has motivated recent studies to examine differences in recovery after sport-related concussion (SRC) by sex. However, heterogeneity in study design, participants, and recovery outcomes has led to mixed findings. Further work is needed to evaluate potential differences by sex and to investigate the role of related characteristics, such as sport contact-level, in recovery timelines. This study aimed to investigate whether concussion recovery trajectories differ by sex, considering a priori clinical and demographic covariates, and accounting for the sequence of recovery outcomes. Our secondary question was whether sport contact-level modifies the relationship between sex and time to outcomes. Using data from the Ivy League–Big Ten Epidemiology of Concussion Study, we included SRCs reported across five academic years; 2015–2020 (February 2020). We used Cox proportional hazards regressions to estimate associations between sex and time from injury to three outcomes: (1) symptom resolution, (2) return to academics, (3) return to full play, accounting for measured confounders.ResultsAmong 1160 SRCs (male, n = 667; female, n = 493) with complete data, median age overall was 20 years (25th-75th percentiles:19–21), and most occurred among athletes playing high-contact sports (78.0%). Males were slightly more likely to complete symptom resolution over time compared to females (HR = 1.18, 95%CI = 1.05–1.33), but results were attenuated in fully adjusted models (HR 1.13, 95%CI = 0.99–1.29). Similarly, the HR of full academic return for males compared to females was 1.22 (95%CI = 1.07–1.38), but was attenuated in fully adjusted models (HR = 1.11, 95%CI = 0.97–1.28). The HR of full return to play for males compared to females was 1.14 (95%CI = 1.02–1.28), and was attenuated after adjustment (HR = 1.06, 95%CI = 0.93–1.20) as well. The interaction between sex and playing a high/low-contact sport was not statistically significant across models, though differences were apparent.ConclusionsAmong a cohort of collegiate athletes with SRC, recovery timelines appeared similar between male and female athletes, adjusting for measured confounders. Differences by sex, considering sport contact-level, were evident and may be important clinically and in future studies. This study used robust methods, accounting for nesting in the sequence of RTP outcomes. Results inform concussion management protocols and planned qualitative work to further elucidate how collegiate athletes experience concussion recovery.Key PointsHeterogeneity in study design, participants, and recovery outcomes has led to mixed findings in determining differences in recovery trajectories after concussion by sex.We found that having longer time to symptom resolution, and also the sequence of having academic return before symptoms resolve and longer time to academic return were confounders in the relationship between sex and RTP timelines. Time to sequential recovery outcomes appeared similar between male and female athletes, adjusting for observable confounders. Further differences by sex were evident when considering contact-level, and may be important to consider clinically and in future research.Results indicate that differences in concussion recovery trajectories by sex may be largely attributed to and driven by differences in sports with a men’s or women’s team only, such as football, and this should be explored further.

Concussion and brain injuries in sport: conceptual, ethical and legal perspectives

ABSTRACT This special issue examines critical ethical, legal, and policy debates surrounding brain trauma in sport, focusing on challenges in concussion management practices and protocols. Brain injury concerns extend beyond traditional contact sports like boxing, encompassing sporting activities involving rapid acceleration, deceleration, and surface impacts, such as cycling and equestrian sports. Among such problems are the identification and management of brain injuries, the roles of officials and healthcare professionals, and the broader implications for sport integrity and athlete careers. The special issue is organized into four sections: ethics of concussion medicine, socio-legal aspects, sport ethical dimensions, and public health policies. Contributions discuss concussion management in youth sport, sport federations’ and athletes’ duties involvement in concussion-related research, strategies to support and enhance athlete autonomy, public health-informed brain injury frameworks, conflict of interest in concussion management protocols, litigation and liability in concussion research and collaboration, race and genomics in brain-injury scientific discourses, rule changes in sport to reduce head impact, the contextual nature of brain injury and athlete decision-making, the ethical use of genetic testing in brain-injury related research, marketing strategies to advertise tackle football to children and adolescents, and policy purposes and evidence underpinning concussion management practices. This comprehensive exploration offers diverse disciplinary insights, making it a crucial resource for sport humanities scholars, policymakers, and medical professionals. Keywords: brain injury, sport ethics, concussion, sport law, sport policy.

'Do it afraid': An arts-based reflexive collective case study exploring youth responses to post-concussion communication changes in daily life.

Concussion and communication researchers have yet to study how post-concussion communication changes affect youths' daily lives. The lack of attention paid to how young people respond to communication changes during concussion recovery constitutes a significant gap in current concussion management research and practices. To explore how youth respond to the effects of post-concussion communication changes in their daily life, including (1) daily routines, (2) relationships with family members, (3) relationships with peers and (4) participation in school/work and community activities. Five youths (16-25 years) and three family members participated in this arts-based reflexive collective case study. Ecocultural theory provided the theoretical framework for study design, data collection and analysis. Cases consist of (1) pre-interview demographic information, (2) three 60-90-min virtual interviews, (3) optional family member interviews, (4) multi-media arts-based participant-generated materials representing participants' experiences of communication change and concussion, and (5) researcher observations, discussions and reflexive journal entries. Reflexive thematic analysis was used to analyse the data. Analysis yielded four themes that illustrate the ways youth navigated and adapted to post-concussion communication changes: (1) navigating changes in communication tasks, daily roles, and identity; (2) re-negotiating relationships and emotional reactions; (3) seeking control and learning to let go during recovery; and (4) helping youth adapt to post-concussion communication changes. The study findings deepen our understanding of the impact of post-concussion communication changes on youths' daily lives and underscore considerations critical to the development ofcommunication-focused concussion education programs and interventions tailored specifically for youth. What is already known on the subject Youth is a critical period of social and emotional development. Communication is integral to identity, relationships, participation in daily activities and well-being. Concussions can affect speech clarity, fluency, understanding and use of language, and social interactions. Re-engaging in routine activities and pre-injury roles can be challenging for youth experiencing communication changes as part of complex concussion recoveries. What this paper adds to the existing knowledge Findings from this research illuminate how youth navigate and adapt to communication changes post-concussion and support the development of youth-focused communication education programs, assessments and interventions. Youth participants actively managed their recoveries by developing innovative strategies to support their communication during daily activities, learning about communication, practicing communication tasks sequentially, and facing fears. Youth also reframed and challenged narrow views of 'normal communication'. What are the potential or actual clinical implications of this work? Findings highlight the need for more youth- and communication-focused education materials and programs within youth concussion management protocols. Information about the specific ecological and sociocultural factors youth encounter during concussion recovery is needed to develop targeted communication-focused education and intervention programs for youth and their families to mitigate risks of isolation, loneliness, and mental health concerns and increase youths' participation in family, community and cultural life. By learning from youth about how communication changes affected their participation in daily activities, identity and relationships, clinicians can provide information and interventions to reduce adverse listener reactions and help young people feel supported and understood.

Return to play after head injury in adolescent sports: evaluating football versus other sports.

Increased adolescent sports participation has raised concerns about higher rates of concussions, a prevalent injury among young athletes with potential long-term effects. Discrepancies in concussion recovery and management protocols across various sports underscore a critical issue in youth athletics. This study aimed to examine the relationship between sport type and the number of games missed following a concussion to inform targeted management strategies. Data from 7445 postinjury ImPACT tests for athletes aged 12-22 years, collected from 2009 to 2019, were analyzed across different sports: baseball, basketball, cheerleading, football, ice hockey, lacrosse, soccer, softball, swimming, track and field, volleyball, and wrestling. The number of days and normalized missed games (NMG), a metric accounting for the different number of games in a season for different sports, were used to evaluate the effect of concussions across different sports. ANOVA, t-tests, and linear regression analyses were performed to model the effect of sport type on games missed in a season while controlling for sex, age, concussion history, diagnosed learning disability (DLD), and attention-deficit/hyperactivity disorder (ADHD). Multivariable linear regression analysis demonstrated that football participation significantly increased NMG (β 1.681, 95% CI 0.807-2.554; p < 0.001) and days missed (β 1.637, 95% CI 1.044-2.231; p < 0.001) after head injury. Concussion diagnoses were also found to significantly increase NMG (β 2.344, 95% CI 1.629-3.059; p < 0.001) and days missed (β 1.560, 95% CI 1.074-2.045; p < 0.001), as well as history of prior concussion (NMG: β 7.791, 95% CI 7.368-8.215; p < 0.001; days missed: β 5.232, 95% CI 4.945-5.520; p < 0.001). In contrast, factors such as age, sex, DLD, ADHD, and concussions causing loss of consciousness did not significantly affect NMG or days missed. ANOVA with Tukey Honest Significant Difference indicated that compared with football, ice hockey (mean difference [MD] 5.4 days, p = 0.011) and track and field (MD 4.1 days, p = 0.006) were associated with significantly more days being missed after head injury. Conversely, basketball (MD -3.0, p < 0.001) and volleyball (MD -2.6, p = 0.005) were associated with fewer missed games. Adolescents playing football missed fewer days and games after concussion than other contact and noncontact sports, including ice hockey and track and field, raising questions about variations in return-to-play protocols and cultural attitudes within sports. Further research is needed to determine the factors affecting games missed across sport types in adolescent athletics and return-to-play protocols.

Match official experiences with the Blue Card protocol in amateur rugby: implementing Rowan’s Law for concussion management

ABSTRACT The Blue Card protocol was introduced to domestic amateur rugby competitions to bring Rugby Canada into compliance with provincial concussion legislation. The Blue Card protocol formalises how match officials can remove an athlete with a suspected concussion from play and prevents athletes from returning to sport without medical clearance. This exploratory study examined the experiences of Canadian rugby match officials with the novel Blue Card process. Semi-structured interviews conducted with six Canadian rugby match officials were subjected to Interpretive Phenomenological Analysis. Findings revealed interpersonal (e.g. stakeholder collaboration and peer support) and intrapersonal (e.g. concerns about personal liability and comfort with the administration of the Blue Card) factors related to the successful implementation of concussion management protocols. Match officials distinguished actions from members of the rugby community as either supporting (e.g. information sharing) or actively resisting (e.g. questioning match official decisions regarding the Blue Card) efforts to implement the Blue Card protocol. Those who had personal experience removing an athlete from play due to a suspected concussion or who administered a Blue Card during the 2019 season reported feeling more comfortable with the process than less experienced peers. However, in this early policy implementation phase, 50% of participants expressed concerns about their personal liability associated with the Blue Card process. Implications for the design and implementation of sport-related concussion research and policy at the amateur level are discussed.

12 Measuring effort on a continuum provides improved insight into concussion baseline cognitive assessments

Objective:Baseline assessment of cognitive performance is common practice under many concussion management protocols and is required for collegiate athletes by the NCAA. The purpose of baseline cognitive assessment is to understand an athlete’s individual uninjured cognitive performance, as opposed to using population normative data. This baseline can then serve as a reference point for recovery after concussion and can inform return-to-play decisions. However, multiple factors, including lack of effort, can contribute to misrepresentation of baseline results which raises concern for reliability during return-to-play decision-making. Measuring effort across a continuum, rather than as a dichotomous variable (good versus poor effort) may provide informative insight related to cognitive performance at baseline.Participants and Methods:Collegiate athletes (n = 231) completed the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) as part of their baseline pre-participation concussion evaluation. ImPACT creates composite scores of Verbal Memory, Visual Memory, Visual-Motor Speed, and Reaction Time. Baseline self-reported symptoms and total hours of sleep the night prior to testing are also collected through ImPACT. ImPACT has one embedded indicator within the program to assess effort, and research has identified an additional three embedded indicators. Athletes were also administered one stand-alone performance validity test, either the Medical Symptom Validity Test (n = 130) or the Rey Dot Counting Test (n = 101), to independently measure effort. Effort was estimated across a continuum (zero, one, two, or three or more failed effort indicators) with both stand-alone and embedded effort indicators. We evaluated the relationship between effort, symptoms, self-reported sleep, Reaction Time composite score and Visual-Motor Speed composite score using a linear regression model.Results:We found that 121 athletes passed all effort indicators, while 39 athletes failed only one effort indicator, 40 athletes failed two effort indicators, and 31 athletes failed three or four (three+) effort indicators. Self-reported symptoms and total hours of sleep were not related to effort, but Reaction Time and VisualMotor Speed composites were. Specifically, performance on the Visual-Motor Speed composite was significantly worse for athletes who failed two or three+ effort indicators compared to athletes who did not fail any, and performance on the Reaction Time composite was significantly worse only for athletes who failed three+ effort indicators. Additionally, athletes who failed one or more effort indicators and reported less sleep performed worse on both the Visual-Motor Speed and Reaction Time composites, compared to those who reported less sleep and did not fail any effort indicators.Conclusions:Athletes who failed one effort indicator did not perform significantly worse on Reaction Time and Visual-Motor Speed composites compared to those who passed all effort indicators. However, 31% of athletes failed two or more effort indicators and these athletes performed worse on cognitive tests, likely due to factors impacting their ability to put forth good effort. These results suggest that effort is more complex than a previously used dichotomous variable and highlights the importance of using several indicators of effort throughout baseline assessments. In addition, the importance of sleep should be emphasized during baseline assessments, especially when effort is questionable.

Concussion Management Among National Collegiate Athletic Association Swim Programs

The nuances of swimming make the application of traditional return-to-play progressions following concussion challenging. Our purpose was to describe athletic training services and concussion management protocols among National Collegiate Athletic Association swim programs and compare them between the National Collegiate Athletic Association divisions. We surveyed 228 athletic trainers assigned to or with knowledge of their institution’s swim programs from a convenience sample of 539 (response rate = 42.3%) athletic trainers. Athletic training services were provided to 98.6% (214/217) of the programs. Nearly 80% (164/207) of the programs administered baseline concussion testing to swimmers, with differences observed between divisions (p &lt; .001). No differences (p = .108) in the number of concussions sustained by swimmers in the past academic year were noted between divisions. Specific return-to-swim protocols were reported by 51.8% (115/222) of respondents with no differences in the presence of a specific return-to-swim protocol between divisions (p = .790). While concussions are reported less frequently in swimming than other sports, appropriate medical care, including a specific return-to-swim protocol, is warranted and provided for future use.

Assessment of a collaborative concussion management strategy in a school-based sport program: Prospective cohort study.

To analyze the implementation of a concussion management protocol in which a team physiotherapist is involved in the identification of concussions and return-to-play (RTP) decisions. A prospective injury surveillance cohort study in a school-based Canadian football program (4 teams; grades 8 to 12) over 4 years. For years 1 to 2, the team physician made all RTP decisions; over years 3 to 4, the team physiotherapist was allowed to make some RTP decisions using pre-established criteria defined in the protocol. A high school in Québec, Que. Male student athletes between 11 and 17 years old. Same-season recurrence (SSR) of concussion symptoms following RTP. A total of 119 concussions were identified (55 during the first 2 years and 64 during the last 2 years) during 27,741 athlete-exposures in 672 athlete-years for an incidence rate of 4.3 per 1000 athlete-exposures. During years 1 to 3, no SSR was observed following RTP clearance. During year 4 there was 1 case of SSR that occurred 11 days after clearance. The overall SSR rate of concussion symptoms following RTP clearance was 0.8%. A very low rate of SSR was achieved whether the team physician made all RTP decisions or the team physiotherapist was allowed to make some of the RTP decisions through the terms of the protocol.

Leadership Lessons in Concussion Management for Team Physicians.

Over the last decade, with emphasis on concussion awareness and potential long-term deficits, concussions have become a public health concern. Although common, concussions are complex in nature and often require a collaborative treatment approach across multiple disciplines. In an athletic setting, the Team Physician plays a critical leadership role in the organization, management, and provision of care for concussed athletes. However, leadership strategies for the provision of concussion care utilized by the Team Physician have not been adequately described. This manuscript intends to describe advanced planning for concussion management and highlight best practices for the provision of care for the concussed athlete, to assist the Team Physician in coordinating optimal care. Specific emphasis will be placed on outlining a concussion management protocol aligned with evidence-based best practices.

A-137 Role of Neuropsychology in Framing and Assisting the Development of Recovery Efforts: Education for Providers across Disciplines

Abstract Objective Information regarding differences in concussion and mild TBI recovery management protocols and recovery expectations vary across disciplines. This often leads to imprecise expectations for prognosis and adverse impacts on effective treatment and recovery. National groups and institutions provide training regarding concussion by neuropsychologists and rehabilitation psychologists to psychologists; however, broadband cross-discipline training is limited. Clinically, psychoeducation and clarification fall on Neuropsychologists and Rehabilitation psychologists. The purpose of this poster is to highlight the importance of the role of neuropsychologists in the education of concussion versus TBI recovery to support medical providers, teachers, and educators to facilitate appropriate care. Data Selection The current literature was review and obtained through the search within various databases such as PsycInfo, Google Scholar, and OhioLink. Keywords such as concussion, mild traumatic brain injury, psychoeducation, and neuropsychology were utilized to provide an inclusive review of the current research (2016–2021). Data Synthesis The focus of existing literature supports the education of concussions for patients and their families. Much of the literature supports the role of many disciplines to aid in recovery. There is limited research to support neuropsychology/Rehabilitation psychology’s efficacy to provide didactic training for providers of different fields supporting this population. Conclusion Through research, advocacy, and program development, the field of Neuropsychology and Rehabilitation psychology can utilize the holistic framework of the brain–body relationship to further facilitate the discussion of concussion and TBI recovery for providers of other disciplines serving these populations. Since treatment is multi-disciplinary for this clinical population, further programmatic evaluation provides interdisciplinary didactics to improve patient care.

Available supports and resources for postsecondary students with traumatic brain injury: A systematic review of the literature

BACKGROUND: Postsecondary students with traumatic brain injuries (TBI) are a rapidly growing population, encompassing those who sustained injuries prior to attending postsecondary education and those who endure injuries during their postsecondary studies. Not only do these individuals face a broad range of symptoms, all of which can affect academic achievement, but they also do not achieve comparable academic outcomes to their peers without disabilities. OBJECTIVE: There is a need to develop and examine the effectiveness of available supports and resources to meet the needs of these students. METHODS: Twenty-three articles were systematically reviewed to illustrate what supports are currently described in the literature for postsecondary students with TBI and what research methods were used to assess the effectiveness of these supports. RESULTS: Three categories of supports emerged, including concussion management protocols, typical study/learning strategies and accommodations, and interventions developed specifically for this population. Findings also indicated a lack of rigorous research methods used to assess these interventions’ effects. CONCLUSIONS: Implications for future research include a need for additional study of all supports and resources described in this review, and assessment of whether or not education professionals, including postsecondary disability services professionals, are aware of and using the tools and strategies addressed in this review.

Brain smart – Let's play safely: Evaluation of a concussion education program in schools

Objectives There are two objectives for this paper. First, to determine effects of a concussion education program in a local school board in terms of concussion-specific knowledge in children and confidence in identifying and managing concussion in adults. Second, to identify differences and similarities in concussion knowledge between children who participate in sports and those who do not and between children with a history of one or more concussions and those without. Design A cross sectional survey regarding concussion knowledge was distributed randomly to students and adults at both pre- and posteducation timepoints. A concussion education program was disseminated across the school board for students between the distribution survey timepoints. Following the education program, adults and students completed their respective post-test surveys. Chi-squared tests in SPSS determined the significance of between-group differences. Results All 17 adults (100.0%) who had received concussion education recently reported confidence in their knowledge of concussion management, compared to 35.7% adults who had not received education for over a year (p = 0.020). For students, all of whom completed the concussion education training between the pre- and post-tests, there were no significant differences in concussion knowledge scores between athletes and non-athletes (either in or outside of school) or between those with a history of concussion and those without. There were no significant changes in concussion knowledge between the pre- and post-tests, except for one question. Conclusion Concussion education programs increase confidence of concussion management protocols in adults involved in sport, but they require improvements to better support knowledge amelioration, particularly for target groups that are at high risk of sustaining another injury.

Medical Supervision of Illinois Public and Private High School Athletics

ABSTRACT Background High-school sports participation in the United States has increased over the years with a corresponding increase in the number of injuries. Leading medical and sports organizations nationwide advocate for an increase in proper medical supervision of athletes. Objectives To analyze athletic medical coverage in Illinois high schools and compare differences between public and private Illinois high school. Methods A survey addressing various components of sports medical coverage was distributed in 2018 to all 810 Illinois High School Association (IHSA) high schools to be completed electronically. Results The response rate was 50% (407/810 schools). Of the responding schools, 14% were private high schools and 86% public high schools. An orthopedic surgeon, family doctor, pediatrician, or another type of physician were present on sidelines in 9.2% of private high schools and 8.5% of public high schools. Athletic trainers (ATs) were present on sidelines in 91% of private high schools and in 79% of public high schools. There was 68% of private high schools reporting coaches trained in CPR versus 85% in public high schools. Both private and public high schools had high rates of having written emergency action plans (89% vs 91%), AED on site (100% vs 99%), written concussion management protocols (96% vs 97%). Conclusion Our study found similar rates of high school medical coverage as compared to national studies, with some significant differences found between private and public high schools. Most Illinois high schools had high rates of having written EAPs, concussion management protocols and AEDs on site. Overall, an increase of medical supervision and emergency preparedness is needed, which should come in the form of increasing AT and physician presence alongside community and school engagement for improved implementation of coverage.

Evaluation of Concussion Management Protocol in Adaptive Sports: The Guidelines for Conducting Proper Baselines

To discuss current concussion management guidelines in Adaptive Sports and educate clinicians on our Concussion Management Protocol (CMP).

Incidence reporting via online high school concussion surveillance by certified athletic trainers and school nurses, 2015\u20132018

BackgroundThere is an increasing concern over adolescent concussions in sports due to risks of long-term negative effects. This study analyzed data over three school years on reported concussion incidence rates by season, high school grade levels and gender, and reported symptoms by school nurses versus athletic trainers, from New Jersey student-athlete concussion data available from an online school-based surveillance system.MethodsSchool nurses and athletic trainers reported 300 concussions within five days from when each occurred over three school years, 2015–2018, in team sports and physical education in New Jersey high schools. Analysis was further conducted on symptoms and number of symptoms reported by school nurses versus school athletic trainers for each documented student-athlete concussion. Estimated concussion incidence rates were calculated using state agency verified school enrollment data.FindingsConcussions most commonly occurred during fall, followed by spring, then winter. Concussion incidence rates ranged from 6.3/1000 (4.99, 7.55) – 9.1/1000 (7.27, 10.98) students over the three school years of the study. Athletic trainers completed 86% of the reports while nurses completed 11% (position or title of 3%, or n = 7, were not disclosed); the values were similar when considering only fall pre-season and regular season sports (88, 10, 2%, respectively). On average, across the three school years, athletic trainers reported about 3.5 symptoms per report while nurses reported 2.7 (values in fall seasons only were 3.7 and 3.1, respectively.)ConclusionsCertified athletic trainers, compared to school nurses, more often completed concussion report forms and reported more symptoms per injured student, perhaps due partly to closer contact and immediate care provided after injury. Additionally, this study had a higher concussion incidence rate during fall sports seasons compared to winter and spring. Future research can further improve our understanding of concussions among adolescent student-athletes to better inform concussion identification, management and recovery protocols.

Evaluating Adherence to Return to School and Activity Protocols in Children After Concussion.

The need to have a pediatric-specific concussion management protocol on Return to School (RTS) and Return to Activity (RTA) after concussion has been recognized internationally. The first step to evaluate the protocol effectiveness is to establish whether children and youth are adhering to these recommendations. The objective of this study was to explore the prevalence and predictors of adherence to RTS and RTA concussion management protocols for children/youth. A prospective cohort of children/youth with concussion. Childhood Disability Research Centre. One hundred thirty-nine children/youth aged 5 to 18 years, diagnosed with concussion and symptomatic upon enrollment, were followed for up to 6 months. Primary recruitment occurred from a Children's Hospital Emergency Department. Provision of RTS/RTA guidelines. Measurement of adherence came from multiple sources, including the child's and parent's knowledge of protocols, research personnel evaluations, and self-reported stages of RTS/RTA and Post-Concussion Symptom Scale (PCSS) scores. Spearman correlations and logistic regression were used, investigating the relationship between PCSS and progression of protocols and determining predictors of adherence. Significant negative associations between total PCSS score and stage of RTS/RTA protocols were found. Fifty-three percent and 56% of the participants adhered to the RTS and RTA protocols, respectively. Children's knowledge of protocols and total PCSS scores significantly predicted adherence to RTS/RTA and may be the most important factors in predicting adherence during recovery from concussion.

Nonverbal hand movement durations indicate post-concussion symptoms of athletes

ObjectiveConcussions are common in sports and appear to be a risk factor for cognitive impairment and mental health problems. Methods of post-concussion diagnosis are still of debate, regarding sensitivity, objectivity, reliability, and costs. Spontaneous displays of nonverbal hand movement behavior during interaction are indicative of psychopathology and relatively simple to record and analyze.BackgroundIncreased durations of continuous (/irregular) body-focused hand movement activity in particular indicates psychopathology that overlaps in symptomatology with that of sport related concussions (SRC). We therefore hypothesized that the duration of irregular, on body, and act on each other hand movements is increased in athletes with SRC who suffer from post-concussion symptoms.Design/MethodsThree matched groups were investigated: 14 symptomatic athletes with a concussion, 14 asymptomatic athletes with a concussion, and 12 non-concussed athletes. Four certified raters analyzed with the NEUROGES analysis system all nonverbal hand movements that were displayed during a videotaped standardized anamnesis about concussion history, incidence, course of action, and post-concussion symptoms.ResultsIrregular Structure units of symptomatic athletes are significantly longer when compared to asymptomatic athletes. Hand movement durations of irregular, on body, and act on each other correlate positively with post-concussion symptoms. The duration of irregular units significantly predicts the PCS score.ConclusionsIncreased durations of irregular hand movement units indicate post-concussion symptoms in athletes with sport-related concussions. Because the recording of spontaneous displays of nonverbal hand movement behavior is relatively simple and cost-efficient, we suggest using the neuropsychological analysis of hand movement behavior as a future diagnostic parameter of concussion management protocols.

Medical Supervision of High School Athletics in Chicago: A Follow-up Study.

Background:High school sports participation in the United States has increased dramatically over the past 25 years. A corresponding increase in the number of injuries has been noted, particularly in contact sports such as football. This has led medical and sports organizations nationwide to advocate for proper medical supervision of athletes at games and practices.Purpose:To gather information from Chicago public high schools to gauge how medical supervision for high school sports has changed in 2017 compared with 2003.Study Design:Cross-sectional study.Methods:Survey questionnaires were sent to the athletic directors of all 99 Chicago public high schools to complete via email. The questionnaire survey contained the same questions as in a survey conducted in 2003 by Tonino and Bollier, with the addition of 4 novel questions relating to emergency action plans (EAPs), automated external defibrillators, concussion management policy, and tackling progression drills.Results:The response rate was 66.67% (66/99 schools). Of the 66 responding schools, all with football programs, no school had a physician on the sideline at home games (decrease from 10.6% in 2003), 37.9% had an athletic trainer present (increase from 8.5% in 2003), and 63.6% had a paramedic available (decrease from 89.4% in 2003). In 2017, 65.6% of responding schools had a coach certified in cardiopulmonary resuscitation (CPR) available at practice to handle medical problems, compared with 89.4% in 2003 (P < .001). Regarding the 4 novel questions, 93.9% of the responding schools had proper tackling progression drills in place, followed by 89.1% who had appropriate EAPs and 93.9% with concussion management protocols, including return-to-play and return-to-learn protocols.Conclusion:Although significant improvement was found in athletic trainer coverage, especially at games, physician coverage was lacking and fewer coaches were certified in CPR in 2017 compared with 2003. EAPs and concussion management protocols were present in most Chicago public high schools. Overall, greater medical supervision is needed, which we believe should come in the form of increased athletic training and physician involvement and coverage, given that expert, expedited medical care saves lives.

Nonverbal Hand Movement Durations Indicate Post-Concussion Symptoms of Athletes.

Methods of post-concussion diagnosis are still under debate with regard to sensitivity, objectivity, reliability, and costs. Spontaneous displays of nonverbal hand movement behavior during interaction are indicative of psychopathology and are relatively simple to record and analyze. Increased continuous (irregular) body-focused hand movement activity in particular indicates psychopathologies that overlap in symptomatology with those of sport-related concussions (SRCs). We therefore hypothesized that the duration of "irregular," "on body," and "act on each other" hand movements is increased in athletes with SRC who suffer from post-concussion symptoms. Three matched groups of 40 athletes were investigated: 14 symptomatic athletes with a concussion, 14 asymptomatic athletes with a concussion, and 12 non-concussed athletes. Using the Neuropsychological Gesture (NEUROGES)-Elan analysis system, four certified raters analyzed all nonverbal hand movements that were displayed during a videotaped standardized anamnesis about concussion history, incidence, course of action, and post-concussion symptoms. The duration of irregular Structure units among symptomatic athletes was significantly longer compared with asymptomatic athletes. Irregular, on body, and act on each other hand movement durations correlated with post-concussion symptoms. Whereas the duration of irregular units significantly predicted the post-concussion symptom score, working memory performances showed only marginal effects. Increased duration of irregular hand movement units indicates post-concussion symptoms in athletes with SRC. Because the recording of spontaneous displays of nonverbal hand movement behavior is relatively simple and cost efficient, we suggest using the neuropsychological analysis of hand movement behavior as a future diagnostic parameter of concussion management protocols.
