Filter by:RESCUE-RACER is jointly sponsored by the University of Cambridge and Cambridge University Hospitals NHS Foundation Trust. The RESCUE-RACER programme evaluates motorsports competitors at baseline (CArBON) and post-injury (CARS). The CArBON study (Competitor Assessment at Baseline; Ocular, Neuroscientific) collects a battery of neuroscientific data in a baseline assessment. The CARS study (Concussion Assessment and Return to motorSport), repeats the CArBON battery throughout the recovery period in competitors who sustain a potentially concussive event during motorsport. The primary outcome of the RESCUE-RACER programme is to establish the natural history of concussive symptoms and signs in motorsport competitors using a comprehensive neuroscientific battery. The standard clinical assessment of concussive symptoms will be correlated with objective clinical scoring, in addition to neurocognitive and neuropsychological assessments. Advanced brain imaging with MRI will be used to further characterize head injuries in motorsport. Finally, salivary biomarkers will be collected to monitor the measurable biological effects of a potentially concussive event immediately following injury and through recuperation in the recovery period. The secondary outcome is investigation of a novel diagnostic tool for concussion, in the form of a 3D head-mounted display and eye tracking system capable of assessing ocular, vestibular and reaction time (OVRT) functions (the I-PAS device, now re-named Dx 100). The results of RESCUE-RACER will form an evidence base for medical decision-making track side after a potentially-concussive incident and will advise on clinic management of motorsports concussion, including the important 'return-to-race' decision.
The aim is to evaluate the study design, procedure and measurements in a randomised controlled pilot study.
The objective of this study is to investigate the treatment effect of repetitive transcranial magnetic stimulation in patients with a history of both persistent post-traumatic headache and post-concussion symptoms. In this double-blind, sham-controlled, concealed allocation, randomized clinical trial, 20 patients aged 18-65 yrs will be recruited from the Calgary Brain Injury Program (CBIP) and the Calgary Headache Assessment and Management Program (CHAMP) / Calgary Chronic Pain Centre, Calgary, Alberta, Canada. Patients will engage in a two-week rTMS treatment protocol (10 treatments) and will be followed for 6 months after therapy.
Neck pain, dizziness and headache are common symptoms following mild traumatic brain injury (mTBI). The efficacy of cervical spine and vestibular-ocular system impairments intervention need to be determined. In this randomized clinical trial, a 6-week personalized clinical rehabilitation program on subacute mTBI will be compare to a conventional approach. The rehabilitation program will include cervical spine exercise combined with manual therapy as well as vestibular-ocular rehabilitation. Overall symptoms will be measured by the Post-Concussion Symptoms Scale (PCSS). Disability and symptoms severity related with neck pain, headache and dizziness will also be evaluated after the treatment period and at 6-week post-treatment.
This study is Part 2 of data collection from 13-25 years old subject population for validation of previously derived algorithms. This data will be combined with that collected under NCT02957461 (Part 1 with subject age range 18-25 years) for the final analyses of validation of the algorithms.
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.
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.
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).
This research aims to develop an intervention that combines mTBI-specific motor and cognitive challenges into a progressive and challenging rehabilitation program. We plan to develop and refine a combined motor and cognitive intervention using healthy athletic young adults (n=12) and people with a positive history of non-resolving mTBI (n=12). We will conduct limited feasibility testing by conducting 6 week training sessions with each subject group. We also plan to identify best measures for determining readiness for duty or full function by incorporating and testing 3 dual-task assessment measures using state-of-the-art wearable sensors to quantify movement.
The overall objective is to provide an onsite diagnosis with subsequent return to play criteria, as well as, lower the risk of traumatic brain injury by primary prevention through cervical spine neuromuscular control and vision training. The central hypothesis is that improved understanding of neurocognitive measures and function will provide improved diagnosis of concussion and help reduce the incidence of subsequent sports-related injury.
