Concussions are common neurologic events that affect many athletes. Very little has been studied on the treatment of concussions with supplements and medications. The U.S. Food and Drug Administration (FDA) reminds us that no supplement has been proven to treat concussions. Many animal studies show that supplements have potential for improving the effects of a brain injury but none have been shown to be of consistent benefit in human studies. Animal studies on severe traumatic brain injury (TBI) may not therefore be applicable transfer to sports-related concussions (SRC)...

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...

Tad Seifert
Neurologic injuries of both an acute and chronic nature have been reported in the literature for various combat sport styles; however, reports of the incidence and prevalence of these injury types vary greatly. Combat sports clinicians must continue to strive for the development, implementation, and enforcement of uniform minimum requirements for brain safety. These health care providers must also seize on the honor to provide this oft-underserved population with the health care advocacy they very much deserve, but often do not receive...

REVIEW
Kenneth Podell, Chase Presley, Howard Derman
The sideline assessment of concussions is a complex multisystem assessment to detect whether an athlete shows signs or symptoms of concussion and should be removed from practice or competition to prevent greater neurologic compromise. Sideline concussion assessments are challenging given some of the environmental conditions, substitution rules of some sports, the possibility of athletes underreporting symptoms, and the difficulties of defining a concussion. The SCAT is the standard of care and is augmented with other procedures to enhance sensitivity and specificity...

Concussion is a complex injury that requires a multimodal assessment to identify and manage the resulting dysfunction. To appropriately manage concussion, clinicians must be aware of the accompanying pathophysiology and dysfunction that occurs following the injury. The current best practice model of care includes symptom, motor, and neurocognitive assessment and management. Furthermore, clinicians should be aware that lifetime accumulation of head impacts may also play a role in neurologic presentation and response to concussion...

BACKGROUND: Epilepsy is one of the most common neurological diseases. Its high prevalence, economic relevance and impact on daily life make it crucial that we study this condition in further detail. Our study seeks to investigate whether the lifestyle of people diagnosed with epilepsy is different to that of people without epilepsy, in order to better understand our patients. METHODS: We designed and delivered a questionnaire about quality of life and daily habits to patients from our hospital's Epilepsy Unit...

Mild Traumatic Brain Injury (mTBI) can result in the acute loss of brain function, including a period of confusion, a loss of consciousness (LOC), focal neurological deficits and even amnesia. Athletes participating in contact sports are at high risk of exposure to large number of mTBIs. In terms of the level of injury in a sporting athlete, a mTBI is defined as a mild injury that does not cause gross pathological changes, but does cause short-term neurological deficits that are spontaneously resolved. Despite previous attempts to model mTBI in mice and rats, many have reported gross adverse effects including skull fractures, intracerebral bleeding, axonal injury and neuronal cell death...

BACKGROUND: Chiari type I malformation (CM-I) is characterised by caudal displacement of the cerebellar tonsils through the foramen magnum, crowding the craniocervical junction. It is being increasingly diagnosed in asymptomatic patients due to the widespread availability of MRI, and there are case reports of these patients suffering sudden death or neurological injury following head or neck trauma, raising the issue of whether they should be prohibited from contact sport participation, given the likelihood of frequent trauma...

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). 179 junior-level contact sport athletes completed preseason testing - 42 reported never having experienced a concussion (Hx-) while 31 had endured three or more (Hx3+)...

Trudy Rebbeck
Synopsis The majority of people with whiplash associated disorder (WAD) do not have neurological deficit or fracture and are therefore largely managed with non-surgical interventions such as exercise, patient education, and behavioral based-interventions. To date clinical guidelines, systematic reviews, and the results of high quality randomized controlled trials recommend exercise and patient education as the primary interventions for people in both acute and chronic stages after injury. However, the relatively weak evidence and small effect sizes in individual trials have led authors of some systematic reviews to reach equivocal recommendations for either exercise or patient education and for policy makers and funders to question whether the more expensive intervention (exercise) should be funded at all...

Low back pain is the most common complaint expressed by adult patients in the primary care setting, and the incidence of low back pain in adolescents is rising. Adolescents who are involved in athletics most commonly suffer from spondylolysis, spondylolisthesis, mechanical low back pain, and herniated disks, whereas adult athletes most commonly suffer from lumbosacral strain and herniated or degenerative disks. Initial nonsurgical management aims to reduce inflammation and noninvasively strengthen damaged tissues...

OBJECTIVE: Traumatic brain injury (TBI) is a major brain injury type commonly caused by traffic accidents, falls, violence, or sports injuries. To obtain mechanistic insights about TBI, experimental animal models such as weight-drop-induced TBI in rats have been developed to mimic closed-head injury in humans. However, the relationship between the mechanical impact level and neurological severity following weight-drop-induced TBI remains uncertain. In this study, we comprehensively investigated the relationship between physical impact and graded severity at various weight-drop heights...

PURPOSE: Radial head arthroplasty (RHA) is a viable treatment for complex radial head fracture. Whereas elbow stability and function is typically restored at short- to mid-term follow-up, the outcome in higher-demand populations is not well defined. We sought to characterize the functional and occupational outcomes following RHA in an active duty military population with intense upper extremity demands. METHODS: We retrospectively reviewed the records of all U.S...

Telehealth refers to health care interactions that leverage telecommunication devices to provide medical care outside the traditional face-to-face, in-person medical encounter. Technology advances and research have expanded use of telehealth in health care delivery. Physical medicine and rehabilitation providers may use telehealth to deliver care to populations with neurologic and musculoskeletal conditions, commonly treated in both acute care and outpatient settings. Patients with impaired mobility and those living in locations with reduced access to care may particularly benefit...

William J Mullally
Concussion has been recognized as a clinical entity for more than 1000 years. Throughout the 20th century it was studied extensively in boxers, but it did not pique the interest of the general population because it is the accepted goal of the boxer to inflict such an injury on their opponent. In 2002, however, the possibility that repetitive concussions could result in chronic brain damage and a progressive neurologic disorder was raised by a postmortem evaluation of a retired player in the most popular sports institution in the United States, the National Football League...

In the quest for a viable non-gravity dependent method to "lift weights" in space, our laboratory introduced iso-inertial resistance (YoYo™) exercise using spinning flywheel(s), more than 25 years ago. After being thoroughly tested in individuals subjected to various established spaceflight analogs, a multi-mode YoYo™ exercise apparatus was eventually installed on the International Space Station in 2009. The method, applicable to any muscle group, provides accommodated resistance and optimal muscle loading through the full range of motion of concentric actions, and brief episodes of eccentric overload...

Emerging evidence indicates that repetitive head impacts, even at a sub-concussive level, may result in exacerbated or prolonged neurological deficits in athletes. This study aimed to: 1) quantify the effect of repetitive head impacts on the alteration of neuronal activity based on functional magnetic resonance imaging (fMRI) of working memory after a high school football season; and 2) determine whether a neck collar that applies mild jugular vein compression designed to reduce brain energy absorption in head impact through "slosh" mitigation can ameliorate the altered fMRI activation during a working memory task...

Repetitive mild traumatic brain injury (rmTBI; e.g., sports concussions) is common and results in significant cognitive impairment. Targeted therapies for rmTBI are lacking, though evidence from other injury models indicates that targeting N-methyl-d-aspartate (NMDA) receptor (NMDAR)-mediated glutamatergic toxicity might mitigate rmTBI-induced neurologic deficits. However, there is a paucity of preclinical or clinical data regarding NMDAR antagonist efficacy in the rmTBI setting. To test whether NMDAR antagonist therapy improves outcomes after rmTBI, mice were subjected to rmTBI injury (4 injuries in 4days) and randomized to treatment with the NMDA antagonist memantine or with vehicle...
