Contact injuries in field hockey and the potential role for personal protective equipment.

Field hockey is played with sticks and a hard ball. It is fast-paced, with athletes playing together in close proximity. Athletes may be at increased risk of sustaining injuries through contact. The aim of this study was to investigate the epidemiological characteristics of contact injuries in field hockey. Data were collected during the 2017/2018 and 2018/2019 Irish Hockey League seasons. This study included two methods of data collection among male athletes: self-reported injuries and via those reported by the teams' physiotherapists. Injuries were defined as any physical complaint sustained during field hockey, supplemented by medical attention and time-loss injuries. Only contact injuries were included for analysis. Overall, 107 contact injuries were incurred, giving rise to an injury incidence rate of 3.1/1000 h, and accounting for 33.1% of all injuries. Athletes had an absolute risk of 0.372 of sustaining a contact injury. Contusions (48.6%) were the most common type of contact injury, while injuries to the head/face (20.6%) were the most frequently reported location. Contact injuries represent an important proportion of all injuries. Rule changes to mandate the use of personal protective equipment in field hockey may assist in reducing the absolute risk and severity of contact injuries in field hockey.

Feasibility and acceptability of a brief intervention to improve mild traumatic brain injury recovery: Problem-solving training-concussion.

OBJECTIVE: Mild traumatic brain injuries (mTBIs) are common among Veterans. Although the majority of neurobehavioral symptoms resolve following mTBI, studies with Veteran samples demonstrate a high frequency and chronicity of neurobehavioral complaints (e.g., difficulties with attention, frustration tolerance) often attributed to mTBI. Recent opinions suggest the primacy of mental health treatment, and existing mTBI practice guidelines promote patient-centered intervention beginning in primary care (PC). However, trial evidence regarding effective clinical management in PC is lacking. This study evaluated the feasibility and acceptability of a brief, PC-based problem-solving intervention to reduce psychological distress and neurobehavioral complaints. RESEARCH METHOD/DESIGN: Mixed method open clinical trial of 12 combat Veterans with a history of mTBI, chronic neurobehavioral complaints, and psychological distress. Measures included qualitative and quantitative indicators of feasibility (recruitment and retention metrics, interview feedback), patient acceptability (treatment satisfaction, perceived effectiveness), and change in psychological distress as measured by the Brief Symptom Inventory-18. RESULTS: The protocol was successfully delivered via in-person and telehealth treatment modalities (4.3 sessions attended on average; 58% completed the full protocol). Patient interview data suggested that treatment content was personally relevant, and patients were satisfied with their experience. Treatment completers described the intervention as helpful and reported corresponding reductions in psychological distress (ES = 1.8). Dropout was influenced by the onset of the COVID-19 pandemic. CONCLUSIONS/IMPLICATIONS: Further study with a more diverse, randomized sample is warranted. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Changes in sport-related concussion and traumatic brain injury in New Zealand during the first two years of the COVID-19 pandemic.

OBJECTIVES: To quantify changes in sport-related concussion and traumatic brain injury claims in New Zealand during the first two years of the COVID-19 pandemic (i.e., 2020 and 2021). DESIGN: Population-based cohort study. METHODS: This study included all new sport-related concussion and traumatic brain injury claims that were registered with the Accident Compensation Corporation in New Zealand during 1 January 2010 to 31 December 2021. Annual sport-related concussion and traumatic brain injury claim rates per 100,000 population from 2010 to 2019 were used to fit autoregressive integrated moving average models, from which forecast estimates with 95 % prediction intervals for 2020 and 2021 were derived and compared against corresponding observed values to obtain estimates of absolute and relative forecast errors. RESULTS: Sport-related concussion and traumatic brain injury claim rates were 30 % and 10 % lower than forecasted in 2020 and 2021, respectively, equating to an estimated total of 2410 fewer sport-related concussion and traumatic brain injury claims during the two-year period. CONCLUSIONS: There was a large reduction in sport-related concussion and traumatic brain injury claims in New Zealand during the first two years of the COVID-19 pandemic. These findings highlight the need for future epidemiological studies examining temporal trends of sport-related concussion and traumatic brain injury to account for the impact of the COVID-19 pandemic.

Higher rates of concussion following COVID-19 infection in high school athletes.

OBJECTIVE: To compare concussion rates (CRs) over one academic year in high school athletes with and without a COVID-19 infection prior to concussion. METHODS: Illness and concussion were prospectively reported for male and female high school athletes across six states over one academic year in the Players Health Rehab surveillance system. Concussion was truncated to 60 days following recovery and return to sport from COVID-19. CRs were estimated per 1000 athletes per academic year and stratified by those who tested positive for COVID-19 infection (with COVID-19) and those who did not (no COVID-19). Poisson regression analyses estimated rate ratio (RR) of concussion controlling for state, gender and an offset of the log athlete participation (with COVID-19 and no COVID-19). RESULTS: Of 72 522 athletes, 430 COVID-19 infections and 1273 concussions were reported. The CR was greater in athletes who reported COVID-19 (CR=74.4/1000 athletes/year, 95% CI 49.6 to 99.3) compared with those who did not (CR=17.2, 95% CI 16.3 to 18.2). Athletes with recent COVID-19 had a threefold higher rate of concussion (RR=3.1, 95% CI 2.0 to 4.7). CONCLUSION: Athletes returning from COVID-19 had higher CRs than those who did not experience COVID-19. This may be related to ongoing COVID-19 sequelae or deconditioning related to reduced training and competition load during the illness and when returning to sport. Further research is needed to understand the association of recent COVID-19 infection and concussion in order to inform preventive strategies.

Association of headgear mandate and concussion injury rates in girls' high school lacrosse.

OBJECTIVES: Headgear use is a controversial issue in girls' lacrosse. We compared concussion rates among high school lacrosse players in an American state with a headgear mandate (HM) to states without an HM. METHODS: Participants included high schools with girls' lacrosse programmes in the USA. Certified athletic trainers reported athlete exposure (AE) and injury data via the National Athletic Treatment, Injury and Outcomes Network during the 2019-2021 seasons. The HM cohort was inclusive of high schools from the state of Florida, which mandates the use of ASTM standard F3137 headgear, while the non-HM (NHM) cohort was inclusive of high schools in 31 states without a state-wide HM. Incidence rate ratios (IRRs) and 95% CIs were calculated. RESULTS: 141 concussions (HM: 25; NHM: 116) and 357 225 AEs were reported (HM: 91 074 AEs; NHM: 266 151 AEs) across all games and practices for 289 total school seasons (HM: 96; NHM: 193). Overall, the concussion injury rate per 1000 AEs was higher in the NHM cohort (0.44) than the HM cohort (0.27) (IRR=1.59, 95% CI: 1.03 to 2.45). The IRR was higher for the NHM cohort during games (1.74, 95% CI: 1.00 to 3.02) but not for practices (1.42, 95% CI: 0.71 to 2.83). CONCLUSIONS: These findings suggest a statewide HM for high school girls' lacrosse is associated with a lower concussion rate than playing in a state without an HM. Statewide mandates requiring ASTM standard F3137 headgear should be considered to reduce the risk of concussion.

The implementation of a neck strengthening exercise program in elite rugby union: A team case study over one season.

OBJECTIVES: To investigate the effect of a neck strengthening program on maximal isometric neck strength and incidence of head and neck injuries including concussion, and to evaluate the acceptability and feasibility of the program within one professional men's rugby union team over one season. DESIGN: Pre- and post-intervention study. METHODS: A phased neck strengthening program was implemented in one rugby union team (n = 26 Forward Group; n = 13 Back Group) throughout the 2020 Super Rugby season, with maximal isometric neck strength measured at each training phase. Strength changes were analysed using one-way, repeated measures analysis of variance and paired samples t-test. Injury data from 2019 to 2020 were compared using incidence rate ratios (IRR). Player and staff surveys, reported as percentage of agreement, assessed program acceptability and feasibility. RESULTS: Forward Group's neck flexors (p < 0.001), left-lateral flexors (p = 0.04) and flexor/extensor ratio (p < 0.001) and Back Group's neck flexors (p = 0.01) significantly improved across the season, with uncertain evidence to support the reduction of head and neck injuries (IRR:0.86 (0.23-2.56) and concussion (IRR:0.63 (0.06-3.34) between seasons. Survey responses revealed high percentages of agreement for the program's acceptability and feasibility. CONCLUSIONS: Targeted sport-specific neck exercises have the potential to increase the maximal isometric neck strength of professional rugby players and may assist in reducing head and neck injuries including concussion.

Comorbid Affective Symptomatology and Neurocognitive Performance in College Athletes.

OBJECTIVES: The current study aims to examine the prevalence rates and the relationship of symptoms of depression, anxiety, and comorbid depression/anxiety with neurocognitive performance in college athletes at baseline. We hypothesized a priori that the mood disturbance groups would perform worse than healthy controls, with the comorbid group performing worst overall. METHODS: Eight hundred and thirty-one (M = 620, F = 211) collegiate athletes completed a comprehensive neuropsychological test battery at baseline which included self-report measures of anxiety and depression. Athletes were separated into four groups [Healthy Control (HC) (n = 578), Depressive Symptoms Only (n = 137), Anxiety Symptoms Only (n = 54), and Comorbid Depressive/Anxiety Symptoms (n = 62)] based on their anxiety and depression scores. Athletes' neurocognitive functioning was analyzed via Z score composites of Attention/Processing Speed and Memory. RESULTS: One-way analysis of variance revealed that, compared to HC athletes, the comorbid group performed significantly worse on measures of Attention/Processing Speed but not Memory. However, those in the depressive symptoms only and anxiety symptoms only groups were not significantly different from one another or the HC group on neurocognitive outcomes. Chi-square analyses revealed that a significantly greater proportion of athletes in all three affective groups were neurocognitively impaired compared to the HC group. CONCLUSIONS: These results demonstrate that collegiate athletes with comorbid depressive/anxiety symptoms should be identified, as their poorer cognitive performance at baseline could complicate post-concussion interpretation. Thus, assessing for mood disturbance at baseline is essential to obtain an accurate measurement of baseline functioning. Further, given the negative health outcomes associated with affective symptomatology, especially comorbidities, it is important to provide care as appropriate.

Effects of the COVID-19 Pandemic on Patients with Concussion Presenting to a Specialty Clinic.

The purpose of this study is to examine the effects of the COVID-19 pandemic on patients presenting with concussion at a specialty clinic. This study used a retrospective cohort design to compare participants (n = 3021) with a suspected concussion, including a Pandemic cohort (n = 1139; March 2020-February 2021) and a Pre-Pandemic cohort (n = 1882; March 2019-February 2020). Concussions and patient characteristics including age, sex, days since injury, and injury mechanism were extracted from an electronic health record. There were 39.5% (n = 743) fewer concussions in Pandemic. Pandemic presented to the clinic 25.8 days later (p < 0.001) and were 1.9 years older (p < 0.001) than Pre-Pandemic. Sport-related concussions decreased 59.6% overall for Pandemic. Pandemic was associated with proportional increases of concussions involving recreational activities (odds ratio [OR] = 6.11; p < 0.001), motor vehicle collisions (OR = 1.39; p < 0.001), and falls/assaults (OR = 1.33; p < 0.001). A total of 9.4% (107/1139) of all Pandemic concussion initial clinical visits were performed using telehealth (0% in Pre-Pandemic). Concussion visit volume to a sub-specialty clinic decreased by approximately 40% during the COVID-19 pandemic and patients presented to the clinic nearly 1 month later. The increase in telehealth highlights the potential to expand clinical care outreach during the current and future pandemics or similar restrictive time periods.

Examining the Emergency Medical Treatment and Active Labor Act: impact on telemedicine for neurotrauma.

The Emergency Medical Treatment and Active Labor Act (EMTALA) protects patient access to emergency medical treatment regardless of insurance or socioeconomic status. A significant result of the COVID-19 pandemic has been the rapid acceleration in the adoption of telemedicine services across many facets of healthcare. However, very little literature exists regarding the use of telemedicine in the context of EMTALA. This work aimed to evaluate the potential to expand the usage of telemedicine services for neurotrauma to reduce transfer rates, minimize movement of patients across borders, and alleviate the burden on tertiary care hospitals involved in the care of patients with COVID-19 during a global pandemic. In this paper, the authors outline EMTALA provisions, provide examples of EMTALA violations involving neurosurgical care, and propose guidelines for the creation of telemedicine protocols between referring and consulting institutions.
