Filter by:200 adolescent rugby players (aged 15-19) from the Senior Cup Teams of 5 Rugby Playing schools (Members of Irish Schools Rugby) will be invited to enroll for inclusion in the study. The study will collect data on brain health, including computer based skill testing, eye tracking and balance and on task completion, cover existing tests in the established SCAT 3 alongside response to exercise testing and a clinical examination including baseline blood tests known to influence recovery from concussion in a rugby playing population of adolescent schoolboys. The initial data will be taken before the 2016/2017 season starts. The volume of rugby training and match play will be recorded along with activity monitoring in general. For those subjects who sustain concussion a dedicated clinic will provide all after care including repeat clinical examination and magnetic resonance imaging along with a graduated return to exercise and a compressive rehabilitation programme at Sports Surgery Clinic (SSC). A Consultant Sports Physician will manage the return to play programme with an exercise, cognitive, balance, eye movement and neck strength programme.
The purpose of this study is to assess cognitive function using a rapid, portable, computerized neurocognitive testing device in a wide variety of clinical settings.
A prospective, single-blind, four-group multi-center randomized controlled trial (RCT) of targeted rehabilitation exercises for vestibular symptoms and impairments (T-REV) in civilians with mild traumatic brain injury (mTBI) will be conducted at the University of Pittsburgh Medical Center Sports Medicine Concussion Program (UPitt). The four treatment groups will consist of the factorial combinations of low (30%) and high (70%) intensity of exercise crossed with low (12-18 min, 1x/day) and high (12-18 min, 2x/day) frequency. A total of 125 participants aged 18-50 years will be enrolled across years 1-4, with approximately 100 participants completing the whole study. After potential participants with mTBI are screened for the vestibular clinical profile, using domain-specific tests and measures, and enrolled into the study, participants will complete primary and secondary outcome measures and receive a home exercise program that a) targets participants individual deficits, and b) is of the appropriate intensity and frequency for the participant's randomly assigned treatment group. Participants will return for in-clinic visits once per week to receive treatment and progress assigned exercises.
About 300,000 people are hospitalized for traumatic brain injury (TBI) each year. After TBI, secondary brain injury escalates due in part to heightened levels of oxidant injury, inflammation, and vascular injury. Traumatic cerebral vascular injury (TCVI) may begin almost immediately after the primary injury and evolve into chronic neurodegenerative conditions. TCVI is a very complex TBI endophenotype and microvascular injuries have been described in a plethora of animal and human TBI studies. These injuries consist of endothelial injury, disruption of the blood brain barrier (BBB), a reduction of capillary density, intravascular microthrombi, and white-matter degeneration. Recently, use of magnetic resonance imaging (MRI)-Blood Oxygen Level Dependent (BOLD) combined with hypercapnia (high spatial and temporal resolution) by our research group has proven to be more sensitive at measuring alterations of cerebral blood flow (CBF) in TBI subjects. The goal of the proposed research is to test the efficacy of Viagra® (sildenafil) at normalizing CBF and improving cognitive outcomes in people that have experienced a TBI. Sildenafil is a phosphodiesterase-5 (PDE-5) inhibitor that has previously been administered as a therapy for high blood pressure and erectile dysfunction. In people that have been affected by stroke-induce neurotrauma, sildenafil improved CBF and was found to be neuroprotective. With respect to chronic TBI, previous studies have demonstrated that sildenafil therapy potentiates cardiovascular reactivity (CVR) in areas of the brain with damaged endothelium. In this proposal, the investigators will test the hypothesis that sildenafil treatment in boxers/Mixed Martial Arts (MMA) fighters soon after concussion normalizes CBF, potentiates CVR, reduces post-concussion symptoms, and improves cognition.
The purpose of this study is to evaluate the effectiveness of brain training in a Virtual Reality set up in neurotypical populations as well as in the traumatic brain injury population.
Sport-related concussions occur during different types of sport and are still an underestimated brain injury. Especially children are affected due to their lacking movement control and thereby at higher risk of situations leading to concussion. However, research about the rehabilitation of balance and coordination in children after sustaining a concussion is lacking. Therefore, the return-to-sport question cannot be answered reliable due to the missing understanding of the underlying mechanisms disturbing coordination, yet. Analyzing postural control, meaning the ability of the body controlled by the brain to maintain balanced, is suggested to be a valid method to investigate movement coordination. A newer method to analyze postural control using reflective marker data will be used to study the rehabilitation process. The findings may help to improve concussion treatment and give implication to the return-to-sport decision. The investigators expect to see an altered postural control after sustaining a concussion visible in the movement amplitude especially short after the injury. Moreover, the researchers assume coordination patterns which are not visible to be altered for an extended time period of up to 30 days as well. Participants will be children aged 10 to 16 years and the aim is to recruit 30 children and adolescents who suffer from a concussion. The data of the concussed participants will be compared with data of healthy volunteers.
Each year millions of Americans suffer concussions as a result of accidents in sports, at work or through military service. Adolescents take the longest to recover from the effects of concussion yet no therapy exists to help speed their recovery. This project aims to see if a program of early guided aerobic exercise can safely speed recovery from concussion in adolescents and investigates some reasons for why this type of therapy could be effective.
This study will prospectively examine the effect of screen time on recovery from concussion. Patients 12 to 25 years of age presenting to the ED with a concussion will be randomized to allow for screen time as tolerated or to abstain from screen time for the first 48 hours of recovery. The amount of screen time use and duration of concussive symptoms will be assessed through daily surveys and a daily post-concussive symptom score (PCSS).
Perhaps no issue in sports medicine has attracted so much media attention and academic interest in recent years as the potential long-term neurodegenerative sequelae of sports-related concussion on athlete's brain health. Rugby has a high incidence of concussion. Recent research findings from a cohort of former professional players found that the number of concussions sustained during their professional careers was associated with the rate of diagnosed clinical depression and late-life cognitive impairment. A limitation of these studies is the use of a self-reported history of concussion. The reliability of professional rugby players to recall and self-report concussion history has never been quantified in the literature to date. Imperfect recall can generate bias in epidemiologic studies when the proportion of events recalled is associated with the health end points of interest. Associations observed may be spurious and due to recall bias if athletes differ in their knowledge and recognition of concussion symptomology in a manner that is associated with the health outcome of interest ie. under/overreporting of concussion. It is difficult to estimate the magnitude of the bias in the absence of any "gold-standard" measure of concussion history. Due to these concerns about the quality of self-reported concussion history, the investigators considered that it was important to evaluate the reliability of self-reported concussion history.
The purpose of this research study is to test whether a portable goggle system (I-PAS) is good at diagnosing mild traumatic brain injury (mTBI) in a community setting. The goal is to determine whether the IPAS goggle system can be used reliably in an urgent care or emergency department setting.
