CONTEXT: Anecdotal and qualitative evidence has suggested that some clinicians face pressure from coaches and other personnel in the athletic environment to prematurely return athletes to participation after a concussion. This type of pressure potentially can result in compromised patient care. OBJECTIVE: To quantify the extent to which clinicians in the collegiate sports medicine environment experience pressure when caring for concussed athletes and whether this pressure varies by the supervisory structure of the institution's sports medicine department, the clinician's sex, and other factors...

BACKGROUND: The Balance Error Scoring System (BESS) is a useful means of measuring postural stability, which frequently exhibits deficits after a concussion. However, it has limited applicability for children since there is insufficient normative data available for the BESS in the pediatric population. The purposes of this study were to report scores for the BESS in children 10 to 17 years old with no history of concussion and to identify whether BESS score is correlated with age, sex, sports participation, height, weight, or body mass index...

INTRODUCTION: Sports-related concussion (SRC) represents an important cause of morbidity in young athletes. Baseline and postconcussive neurocognitive testing is useful in managing concussed athletes. The Concussion in Sport Group has postulated that the use of psychotropic medications is a modifying factor in the management of SRC. About 7% of US adolescents are prescribed psychotropics in a given year. Our aim was to investigate whether psychotropic medication use or history of depression and/or anxiety affects baseline neurocognitive test scores...

Time to symptom resolution, return to school, and return to play after a sport-related concussion in children and adolescents (8-17 years of age) was examined using a retrospective cohort design. A total of 198 patients aged 8 to 17 years were included, with a mean age of 13.5 years (SD = 2.2). Patients aged 8 to 12 years were symptom-free in a median of 12.0 (range 1-60) days whereas 13- to 17-year olds were symptom-free in a median of 14.0 (range 1-300) days (P = .04). Patients aged 8 to 12 years returned to learn in a median of 4...

OBJECTIVE: Concussion is the most common type of traumatic brain injury, and results from impact or impulsive forces to the head, neck or face. Due to the variability and subtlety of symptoms, concussions may go unrecognized or be ignored, especially with the pressure placed on athletes to return to competition. The King-Devick (KD) test, an oculomotor test originally designed for reading evaluation, was recently validated as a concussion screening tool in collegiate athletes. A prospective study was performed using high school football players in an attempt to study the KD as a concussion screening tool in this younger population...

UNLABELLED: Abstract Objective: To assess the characteristics of current clinical trials investigating the treatment of concussion. BACKGROUND: Recent systematic literature reviews have concluded that there is minimal evidence to support any specific treatment for concussion, including the principles of return-to-activity protocols such as type or duration of rest. DESIGN/METHODS: Clinical trial data was extracted from and seven additional World Health Organization primary registries...

OBJECTIVE: This study reviewed several topics related to post-concussion syndrome and psychological factors associated with concussion. Topics include neurobiological perspectives, psychological predictors of post-concussion syndrome including pre-morbid anxiety, anxiety sensitivity and cognitive biases and misattribution. In addition, the iatrogenic effects of excessive rest are reviewed and treatment options are discussed briefly. MAIN RESULTS: Animal models of concussion and mild traumatic brain injury suggest that a concussion can result in anxiety and fear reactions...

Pediatric mild traumatic brain injury (pmTBI) is the most prevalent neurological insult in children and is associated with both acute and chronic neuropsychiatric sequelae. However, little is known about underlying pathophysiology changes in gray matter diffusion and atrophy from a prospective stand-point. Fifteen semi-acute pmTBI patients and 15 well-matched healthy controls were evaluated with a clinical and neuroimaging battery, with a subset of participants returning for a second visit. Clinical measures included tests of attention, processing speed, executive function, working memory, memory, and self-reported post-concussive symptoms...

The aim of this study was to determine the frequency, mechanism(s), and impact of recurrent traumatic brain injury (TBI) over a 1-year period. Population-based TBI incidence and 1-year outcomes study with embedded case-control analysis. All participants (adults and children) who experienced a recurrent TBI (more than one) in the 12 months after an index injury and matched controls who sustained one TBI within the same period were enrolled in a population-based TBI incidence and outcomes study. Details of all recurrent TBIs sustained within 12 months of the initial index injury were recorded...

The Balance Error Scoring System (BESS) is widely recognized as an acceptable assessment of postural control for adult patients following a mild traumatic brain injury (mTBI) or concussion. However, the measurement properties of the BESS as a post-mTBI assessment test for younger patients are not well understood. The purpose of this study was to evaluate the utility of the BESS as a post-mTBI assessment test for children and adolescents aged 8 to 18 years through 2 investigations: (1) a retrospective medical records review of the relationship among age, BESS scores, and other common post-mTBI assessment tests; and (2) a prospective study comparing BESS scores for a cohort of children with a recent mTBI and BESS scores for a cohort of matched healthy peers...

The objective of this study was to determine whether the type of intracranial traumatic lesions, the number of simultaneous traumatic lesions, and the occurrence of skull and facial bone fractures have an influence on S100 calcium binding protein B (S100B) serum levels. Patients with blunt traumatic brain injury were prospectively enrolled into this cohort study over a period of 13 months. Venous blood samples were obtained prior to emergency cranial CT scan in all patients within 3 h after injury. The patients were then assigned into six groups: 1) concussion, 2) epidural hematoma, 3) subdural hematoma, 4) subarachnoid hemorrhage, 5) brain contusions, and 6) brain edema...

Concussions are common in athletes and often go unreported. A likely contributor to underreporting of concussions in athletes is lack of knowledge of concussion-related symptoms. The current study assessed concussion symptom knowledge in 382 Division I athletes and 230 nonathletes. Participants were asked to identify potential symptoms following a concussion from a list of both real symptoms and distractors. Student-athletes expected significantly more total symptoms following a concussion than did nonathletes, and they correctly identified symptoms such as nausea and/or vomiting and being easily upset by loud noises more frequently than controls...

As the number of high school students participating in athletics continues to increase, so will the number of sports-related concussions unless effective concussion prevention programs are developed. We sought to develop and validate a cost-effective tool to measure neck strength in a high school setting, conduct a feasibility study to determine if the developed tool could be reliably applied by certified athletic trainers (ATs) in a high school setting, and conduct a pilot study to determine if anthropometric measurements captured by ATs can predict concussion risk...

OBJECTIVE: To determine why athletes decide not to seek medical attention during a game or practice when they believe they have suffered a concussion. DESIGN: A retrospective survey. SETTING: University Sport Medicine Clinic. PARTICIPANTS: A total of 469 male and female university athletes from several varsity team sports were participated in the study. MAIN OUTCOME MEASURES: Athletes were surveyed about the previous 12 months to identify specific reasons why those athletes who believed they had suffered a concussion during a game or practice decided not to seek attention at that time, how often these reasons occurred, and how important these reasons were in the decision process...

BACKGROUND/AIM: Concussion is a common injury in sport. Most individuals recover in 7-10 days but some have persistent symptoms. The objective of this study was to determine if a combination of vestibular rehabilitation and cervical spine physiotherapy decreased the time until medical clearance in individuals with prolonged postconcussion symptoms. METHODS: This study was a randomised controlled trial. Consecutive patients with persistent symptoms of dizziness, neck pain and/or headaches following a sport-related concussion (12-30 years, 18 male and 13 female) were randomised to the control or intervention group...
