Nathan Gibbs, Mark Watsford
BACKGROUND: Concussion incidence rates in professional Australian football may be underreported due to the injury classification definition. A myriad of factors contribute to concussion risk; however, there is limited long-term surveillance in Australian football. This study analysed concussion in one Australian football team over an extended period. METHOD: Match-play concussion injuries in one team (n = 116 participants) were diagnosed and treated by the team physician over 14 years...

Dmitry Esterov, Brian D Greenwald
A mild traumatic brain injury (mTBI) is a complex pathophysiologic process that has a systemic effect on the body aside from solely an impairment in cognitive function. Dysfunction of the autonomic nervous system (ANS) has been found to induce abnormalities in organ systems throughout the body, and may contribute to cardiovascular dysregulation and increased mortality. Autonomic dysfunction, also known as dysautonomia, has been studied in moderate and severe TBI, and has emerged as a major contributing factor in the symptomatology in mTBI as well...

Sport-related concussions in young athletes are common, generally under reported and often go unrecognized. Concussion in sport may result either from a direct impact to the head or from indirect forces transmitted to the brain from impact elsewhere on the body. Concussions may also result from sudden acceleration, deceleration or rotational forces to the brain. The key features of concussion include confusion, impaired memory and reduced speed of information processing. Recovery may occur from a few days to several weeks or months...

Dilip R Patel, Diana Fidrocki, Venu Parachuri
Sport-related concussions in young athletes are common, generally under reported and often unrecognized. Preventive strategies include education, modification of sport rules, use of equipment such as headgears, face masks and mouth guards, and neck muscle training. Evidence is limited to support effectiveness of these preventive measures with the exception of rule modification in some sports. In the United States, laws have been enacted that require medical evaluation and clearance prior to return to play; however, evidence thus far does not show that laws have been effective in reducing the incidence of concussions in sport...

Purpose: In this article, we describe an academic concussion management protocol designed for grades Pre-K to 12, called Cognitive Return to Exertion (CoRTEx). Collaboration between the speech-language pathologist (SLP) and athletic trainer (AT) is highlighted. Method: A description of CoRTEx is provided, and the need for collaboration is emphasized. A case study illustrates an example of how CoRTEx can be implemented at the individual student level. Results: A total of 165 students went through CoRTEx from the pilot in April 2014 through December 2016...

BACKGROUND: The risk of sport-related concussion (SRC) has emerged as a major public health concern. In rare instances, sport-related head injuries can be even more severe, such as subdural hemorrhage, epidural hemorrhage, or malignant cerebral edema. Unlike SRCs, sport-related structural brain injury (SRSBI) is rare, may require neurosurgical intervention, and can lead to permanent neurologic deficit or death. Data characterizing SRSBI is limited and many have recognized the need to better understand these catastrophic brain injuries...

Noncontact sports are associated with a variety of neurologic injuries. Concussion, vascular injury (arterial dissection), and spinal cord trauma may be less common in noncontact sports, but require special attention from the sports neurologist. Complex regional pain disorders, muscle injury from repetitive use, dystonia, heat exposure, and vascular disorders (patent foramen ovale), occur with similar frequency in noncontact and contact sports. Management of athletes with these conditions requires an understanding of the neurologic consequences of these disorders, the risk of injury with return to play, and consideration for the benefits of exercise in health restoration and disease prevention...

Sports-related concussions (SRCs) are common among athletes in the United States. Most athletes who sustain an SRC recover within 7 to 10 days; however, many athletes who sustain the injury do not recover as expected and experience prolonged, persistent symptoms. In this document, the authors provide an overview of the empirical evidence related to the use of blood-based brain biomarkers in the athlete population for diagnosis of SRCs, prognosis of recovery and return to play guidelines, and indications of neurodegeneration...

CONTEXT:   Dynamic balance deficits have been described postconcussion, even after athletes return to play. Lower extremity (LE) musculoskeletal injury rates increase for up to 1 year after concussion, but the long-term musculoskeletal implications of concussion are unclear. OBJECTIVE:   To (1) examine the association of concussion and LE injury histories with osteoarthritis (OA) prevalence in retired National Football League players and (2) examine the association of concussion and LE injury histories with OA prevalence in those ≤55 years of age...

BACKGROUND: Concussion diagnosis and management remains a largely subjective process. This investigation sought to evaluate the utility of a novel neuroelectric measure for concussion diagnosis and return to play decision-making. HYPOTHESIS: Brain Network Activation (BNA) scores obtained within 72-h of injury will be lower than the athlete's preseason evaluation and that of a matched control athlete; and the BNA will demonstrate ongoing declines at the return to play and post-season time points, while standard measures will have returned to pre-injury and control athlete levels...

Sport-related concussion has been shown to alter cerebral blood flow (CBF) both acutely and chronically, and may exert cumulative effects across multiple injuries. Such dysfunction may be mediated by trauma-induced deficits to CBF control mechanisms, though our understanding of these effects is limited, including dynamics of neurovascular coupling (NVC) responses (i.e., CBF responses to neurologic demand). A total of 179 junior-level contact sport athletes completed preseason testing; 42 reported never having experienced a concussion (Hx(-)) while 31 had endured three or more (Hx(3+))...

BACKGROUND: Baseline visual acuity (VA) loss from static to dynamic head conditions assessed using the Dynamic Visual Acuity Testing (DVAT) have not been established in NCAA football players. DVAT assesses the Vestibulo-Ocular Reflex (VOR) which is measured in Logarithm of the Minimum Angle of Resolution (logMAR). Decreased VA beyond baseline measures may detect VOR impairment and impact treatment protocols and assist in return to play decisions post-concussion. HYPOTHESIS/PURPOSE: To establish normative VA mean scores during a static head posture as well as dynamically during the DVAT with a head speed of 150 deg/s in the pitch (vertical) and yaw (horizontal) planes rotating 20 degrees in each direction...

BACKGROUND: The prevalence of primary headache disorders in the general population provides a unique challenge in the evaluation of headache occurring in the context of sport. Despite a wealth of studies exploring the epidemiology of headache in the layperson, little is known about the prevalence and nature of headaches in collegiate student-athletes. These scenarios are challenging in the return to play context, as it is often unclear whether an athlete has an exacerbation of a primary headache disorder, new onset headache unrelated to trauma, or has suffered a concussive injury...

Kathryn L Higgins, Robert L Denney, Arthur Maerlender
The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called "sandbagging," in order to return to their baseline cognitive scores, and thus to play, more quickly...
