Concussion

BACKGROUND: Concussion, or mild traumatic brain injury, is a growing public health concern, affecting approximately 1.2% of the population annually. Among children aged 1-17 years, concussion had the highest weighted prevalence compared to other injury types, highlighting the importance of addressing this issue among the youth population. OBJECTIVE: This study aimed to assess adherence to Return to Activity (RTA) protocols among youth with concussion and to determine if better adherence affected time to recovery and the rate of reinjury...

OBJECTIVE: To examine the likelihood of head acceleration events (HAEs) as a function of previously identified risk factors: match time, player status (starter or substitute) and pitch location in elite-level men's and women's rugby union matches. METHODS: Instrumented mouthguard data were collected from 179 and 107 players in the men's and women's games and synchronised to video-coded match footage. Head peak resultant linear acceleration (PLA) and peak resultant angular acceleration were extracted from each HAE...

The unconsolidated motor and cognitive skills that are typical of the early childhood period place infants, toddlers, and preschoolers at risk for a variety of traumatic injuries. Such injuries may include mild traumatic brain injury or concussion. Knowledge regarding the risk, diagnosis, outcomes, and management of early childhood concussion is limited, especially compared with what is known about concussion in school-age children, adolescents, and adults. This state-of-the-art review aims to provide current knowledge on the epidemiology, physical signs, behavior, and clinical outcomes associated with early childhood concussion...

CONTEXT: Evidence indicates a 2 to 3 times increased risk of musculoskeletal injury after return to play from concussion. Undetected neuromuscular control deficits at return to play may relate to increased musculoskeletal injury risk. Rehabilitation to improve neuromuscular control may benefit patients with concussion, but access to rehabilitation professionals and/or poor adherence may limit efficacy. Our purpose was to determine the feasibility of an 8-week virtual neuromuscular training (NMT) program administered through a novel smartphone application among physically active, uninjured adults...

This exploratory video analysis study aimed to review characteristics of potential head injury situations during a men's professional international football tournament. For 64 matches of the FIFA World Cup Qatar 2022™ FIFA analysts used match footage to record all potential head injury situations. A potential head injury situation was defined as a player staying down for more than 5 s and/or requesting medical attention, and where the body impact location included the player's head. Characteristics were further recorded for match, player (i...

BACKGROUND: There is a research gap in the survey of injuries and illnesses in the sport of luge. OBJECTIVE: To analyse the type, frequency and burden of injuries and illnesses that occurred over a preparation period and a competition period in elite luge athletes. METHODS: In total 40 elite luge athletes, who were all part of a national team and competed internationally, self-reported acute injuries, overuse injuries and illnesses weekly using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems...

Sports concussion is a common and costly injury, and increased public injury awareness could help reduce costs. Many factors, including public messages about sports concussion by the sports media, shape public injury awareness. Empirical analyses show that this messaging can be poor. The proposed solutions include providing media guidance, but little is known about this topic. This scoping review will enable a systematic search and synthesis of guidance materials for improved health messaging of sports concussion by the mass media...

Intimate partner violence (IPV) is a major global concern, and IPV victim-survivors are at an increased risk of brain injury (BI) due to the physical assaults. IPV-BI can encompass both mild traumatic brain injury (mTBI) and non-fatal strangulation (NFS), but IPV-BI often goes undetected and untreated due to a number of complicating factors. Therefore, the clinical care and support of IPV victim-survivors could be enhanced by BI screening and assessment in various settings (e.g., first responders, emergency departments, primary care providers, rehabilitation, shelters, and research)...

The epidemiology of injury among subgroups of minors, older adults, students, and athletes has previously been investigated; however, studies investigating employee-related injuries are limited. We aimed to retrospectively analyze the epidemiological characteristics and dynamic change trends of injury among employees over a nine-year period in a coastal area in China to provide a reference for formulating injury prevention and control measures among employees. All 14,168 employee injury cases registered in a hospital injury monitoring system were analyzed from January 2013 to December 2021...

Following a mild traumatic brain injury (mTBI; also known as concussion), physiotherapists may be involved in injury identification, assessment and rehabilitation. However, how people perceive and experience the physiotherapist's role is not well understood. Semistructured interviews were undertaken with patients who saw a physiotherapist individually or as part of a multidisciplinary team following mTBI in New Zealand. Interviews were recorded, transcribed verbatim and analysed using the interpretive descriptive approach...

Traumatic brain injury (TBI) is a leading cause of long-term disability across the world. Evidence for the usefulness of imaging and fluid biomarkers to predict outcomes and screen for the need to monitor complications in the acute stage is steadily increasing. Still, many people experience symptoms such as fatigue and cognitive and motor dysfunction in the chronic phase of TBI, where objective assessments for brain injury are lacking. Consensus criteria for traumatic encephalopathy syndrome, a clinical syndrome possibly associated with the neurodegenerative disease chronic traumatic encephalopathy, which is commonly associated with sports concussion, have been defined only recently...

OBJECTIVES: Evaluate professional rugby players' self-reported perceived understanding of the head injury assessment (HIA) and return to play (RTP) processes and determine factors related to understanding and trust pertaining to these processes. METHODS: An electronic survey measured concepts of interest. A thematic analysis of player understanding was performed, and player statements were coded. RESULTS: 207 U.S. Major League Rugby (MLR) players participated (26...

Mild traumatic brain injury (mTBI) is known to result in chronic somatic, cognitive, and emotional symptoms. Depression is commonly reported among individuals suffering from persistent concussion symptoms; however, the underlying mechanisms are not understood. The glutamatergic system has recently been linked with mTBI and depression due to reports of similar changes in expression of glutamatergic proteins. Using a closed-head controlled cortical impact (cCCI) model in adult male rats (n = 8/group), this study investigated the emergence of self-care deficits and changes in social interaction behaviors at four, eight and twelve weeks post-injury...

Engaging community members is essential for successful development, implementation, and sustainability of viable interventions. The objective of this study is to develop and pilot test an evidence-based intervention to reduce head impact exposure in youth American football (i.e., football), using a community-engaged approach...

Crown fractures with pulp exposure in mature permanent teeth present a challenging situation that requires immediate attention. Mineral trioxide aggregate (MTA) as a sealing material after pulpotomy has proven to be a reliable treatment in these cases compared to traditional root canal therapy. This case report emphasizes the importance of early diagnosis and careful treatment planning for complicated crown fractures and concussion injuries in a mature permanent incisor of a young child. Total pulpotomy using MTA has proven to be an effective treatment for fractures in young mature incisors with pulp exposure, as evidenced by a one-year follow-up in our case, which showed no discoloration...

Intimate partner violence is a serious, but underappreciated, issue that predominantly affects women and often results in concussion (i.e., mild traumatic brain injury). However, concussion in intimate partner violence is unique because it often involves a concomitant strangulation which may exacerbate or alter the physiology and clinical presentation of the brain injury. Therefore, here we conducted human and rodent studies to provide insight into knowledge gaps related to the detection, pathophysiology, and functional consequences of intimate partner violence-related brain injury...
