Sports related concussion

AIMS: We applied the 2021 consensus criteria for both chronic traumatic encephalopathy neuropathological change and traumatic encephalopathy syndrome in a small case series of six former elite-level Australian rugby code players. METHODS: Neuropathological assessment of these cases was carried out at the Sydney and Victorian Brain Banks. Clinical data were collected via clinical interviews and health questionnaires completed by the participants and/or their next of kin, and neuropsychological testing was conducted with participants who were capable of completing this testing...

Sport-related concussion (SRC) is a serious injury in youth team sports, including handball. While research on the prevention of SRC has made progress over the past 5 years, prevention strategies are lacking in handball. The aim was to explore and develop strategies focusing on information, rules and training that may prevent concussion in youth handball by incorporating knowledge from experts and end users. Using a participatory methodology, experts (physiotherapy, biomechanics: n=3) and end users (players, coaches, referees, coach educators: n=7) contributed their experience and knowledge in a 2-hour online workshop...

Sports-related concussions may cause white matter injuries and persistent post-concussive symptoms (PPCS). We hypothesized that athletes with PPCS would have neurocognitive impairments and white matter abnormalities which could be revealed by advanced neuroimaging using ultra-high field strength diffusion tensor (DTI) and diffusion kurtosis (DKI) imaging metrics and cerebrospinal fluid (CSF) biomarkers. A cohort of athletes with PPCS of a severity limiting the ability to work/study and participate in sport school and/or social activities for ≥ 6 months completed 7T MRI (morphological T1-weighed volumetry, DTI and DKI), extensive neuropsychological testing, symptom rating and CSF biomarker sampling...

PURPOSE: Many sports-related concussion (SRC) outcomes can be prevented by removing affected athletes and allowing return after full recovery. Diagnosing concussions on the side-line is challenging, as tools often rely on visual performance assessment. Since acute exercise can affect vision, it is vital to determine if exercise can mask potential brain injury if visual performance assessments are used. The aim of this study was to determine the effect of a single bout of maximal aerobic exercise on acute visual performance...

CONTEXT: Assessment of sport-related concussion (SRC) has begun to include patient- reported outcome measures (PROMs). However, there is a limited understanding of which health limitations are most meaningful to adolescents following SRC. OBJECTIVE: To explore patient-perceived activity limitations following SRC and throughout recovery to return-to-play (RTP) and mapped according to the International Classification of Functioning, Disability, and Health (ICF) model...

Concussion in para athletes with vision impairment (VI) is poorly understood. Recently published studies have suggested that athletes with VI may be more likely to sustain sport-related concussions compared to non-disabled athletes and athletes with other impairment types. There is a critical need for objective concussion incidence measures to determine concussion injury rates and risks more accurately. The aim of this review was to examine the limited available evidence of concussion incidence rates across six different para sports for athletes with VI and encourage the future collection of concussion incidence data and the adoption of injury prevention strategies in VI para sport...

Sport-related concussion (SRC) can impair the cerebrovasculature both acutely and chronically. Transcranial Doppler (TCD) ultrasound assessment has the potential to illuminate the mechanisms of impairment and provide an objective evaluation of SRC. The current systematic review investigated studies employing TCD ultrasound assessment of intracranial arteries across three broad categories of cerebrovascular regulation: neurovascular coupling (NVC), cerebrovascular reactivity (CVR), and dynamic cerebral autoregulation (dCA)...

Neurovascular coupling (NVC) uniquely describes cerebrovascular response to neural activation and has demonstrated impairments following concussion in adult patients. It is currently unclear how adolescent patients experience impaired neurovascular coupling acutely following concussion during this dynamic phase of physiological development. The purpose of this study was to investigate NVC in acutely concussed adolescent patients relative to controls. We recruited patients presenting to a sports medicine practice within 28 days of a concussion or a musculoskeletal injury (controls)...

Mild traumatic brain injuries (mTBI) are often caused by a blow to the head or a sudden jolt resulting in a wide range of physical, cognitive, and emotional temporary symptoms. Mild TBI diagnosis can be challenging and most commonly followed by post-concussion syndrome (PCS). When the symptoms are present for more than 3 months, prolonged post-concussive syndrome (PPCS) can be suspected. This review aims to identify and summarize the current status of the knowledge regarding the risk factors and predictors of the recovery from PCS and PPCS...

INTRODUCTION: Musculoskeletal (MSK) injuries in US trail sports are understudied as trail sport popularity grows. This study describes MSK injury patterns among hikers, trail runners, and mountain bikers from 2002 through 2021 and investigates MSK injury trends acquired during mountain sports. METHODS: The National Electronic Injury Surveillance System (NEISS) was used to identify US emergency department (ED) patients from 2002-2021 (inclusive) who endured MSK injuries during hiking, trail running, or mountain biking...

OBJECTIVES: People may experience a myriad of symptoms after mild traumatic brain injury (mTBI), but the relationship between symptoms and objective assessments is poorly characterized. This study sought to investigate the association between symptoms, resting heart rate (HR), and exercise tolerance in individuals following mTBI, with a secondary aim to examine the relationship between symptom-based clinical profiles and recovery. METHODS: Prospective observational study of adults aged 18 to 65 years who had sustained mTBI within the previous 7 days...

Sport-related concussion (SRC) is a prevalent injury. There are significant disparities in SRC outcomes across racial and ethnic groups. These disparities may be attributed to the unequal distribution of political power (or influence) and resource allocation in various communities shaping individuals' social determinants of health (SDoH). However, the influence of SDoH on SRC outcomes remains understudied. In this clinical commentary we use the National Institute of Minority Health and Health Disparities Research Framework and describe how it's application can help address gaps in our understanding of SDoH and SRC...

BACKGROUND: Concussion is a pathophysiological process that occurs due to a traumatic biomechanical force. Concussions are an "invisible" and common traumatic brain injury with symptoms that may be underestimated. This necessitates fundamental improvements in public knowledge specifically addressing young university athletes and different genders. This cross-sectional study aimed to explore the possibility of gender differences with respect to university student athletes' concussion knowledge, attitude and reporting behaviors...

BACKGROUND: Sport-related concussion (SRC) is a traumatic brain injury that occurs during sport or exercise activity. SRC is a growing health concern in Australia, with increasing public awareness and presentations to general practitioners being increasingly common. OBJECTIVE: This article will focus on the assessment and management of SRC in general practice, including guidance for returning patients to sport. Concussion prevention, potential long-term complications, and the decision-making process regarding retirement from sport are beyond the scope of this article...

There is still much uncertainty surrounding the approach to diagnosing and managing a sport-related concussion (SRC). Neurobiological recovery may extend beyond clinical recovery following SRC, highlighting the need for objective physiological parameters to guide diagnosis and management. With an increased understanding of the connection between the heart and the brain, the utility of assessing cardiovascular functioning following SRC has gained attention. As such, this review focuses on the assessment of cardiovascular parameters in the context of SRC...

OBJECTIVE: To examine whether a "letter to my future self" analyzed using structural topic modeling (STM) represents a useful technique in revealing how participants integrate educational content into planned future behaviors. METHODS: 453 club-sports athletes in a concussion-education randomized control study wrote two-paragraph letters describing what they hoped to remember after viewing one of three randomly assigned educational interventions. RESULTS: A six-topic solution revealed three topics related to the content of the education and three topics related to the participant behavioral takeaways...

OBJECTIVE: To assess student-athletes' knowledge and attitudes towards sport-related concussions and to investigate concussion history and reporting behaviours. METHODS: The cross-sectional, survey-based study was conducted from September 2020 to June 2021 after approval from the research ethics committee of Universiti Malaya, Malaysia, and comprised student-athletes of either gender aged 18 years or above at various universities across Pakistan and who played contact or collision sports for their universities...

The aim of the present study was to evaluate the characteristics of match injury in male beach soccer players. Video recordings of all official beach soccer tournaments in which the European national male beach soccer teams participated from 2018 to 2021 were analysed by two sports medicine specialists retrospectively. Regarding each injury, data including the mechanism, location of the injury, whether the injury led to time-loss, and the relationship of the injury to the bicycle kick (BK), etc. were documented...

PURPOSE: The aim was to describe the demographic and post-injury factors that influence time to return to learn (RTL) among student-athletes enrolled in the Concussion Assessment, Research and Education (CARE) Consortium. METHODS: A total of 47,860 student-athletes enrolled in the National Collegiate Athletic Association-Department of Defense (NCAA-DoD) CARE Consortium study from 2014 to 2020, with 1485 sport-related concussions (SRCs) analyzed in the present dataset...

Sport-related concussion incidence has increased in many team-based sports, such as rugby, Gaelic (camogie, hurling, football), and hockey. Concussion disrupts athletes' brain function, causing an "energy crisis" that requires energy and nutrient support to restore function and heal. Performance dietitians and nutritionists play a role in supporting athletes' post-injury nutritional demands. This study aimed to investigate Irish performance dietitians' and nutritionists' knowledge and implementation of nutritional strategies to manage and support athletes' recovery following concussion...
