"Severe traumatic brain injury (TBI) is a serious condition, common in young adults. It leads to sensorimotor and cognitive sequelae that hinder social reintegration. Neuronal plasticity must be used quickly before natural recovery impedes neuronal regrowth. In this respect, stopping sedation as soon as possible and early mobilization, even if the patients are unconscious, are recognized as useful measures to promote recovery. However, at the early stage, the environment of the ICU and the acute condition of the patients limit the rehabilitation possibilities. In such a context, functional proprioceptive stimulations (Vibramoov™ system, Techno Concept, France) could be a tool of interest. By using the proprioceptive signatures of cyclic movements, proprioceptive stimulations can elicit the illusion of these movements. A motor response can even be obtained through the interactions between the peripheral nervous system and the central nervous system. Finally, such stimulations facilitate the initiation of the mimicked movements. Some studies have already shown the benefits of proprioceptive vibrations. However, so far, these benefits have only been studied at the chronic stage of neurological diseases. The investigators hypothesized that early functional proprioceptive stimulations (FPS) may reduce spasticity and promote recovery in patients with severe traumatic brain injury. To test the hypothesis, the investigators conduct a randomized controlled trial on patients with severe traumatic brain injury. Every patient will be included as soon as possible in the ICU and receive either FPS, either sham stimulations to the joints of the lower limbs, 4 times a week during 8 weeks. The primary outcome measures will assess spasticity. The investigators also assess pain, coma recovery; muscle wasting and cognitive impairments. "
By longitudinal, prospective research in children with neurodisabilities including severe motor impairments and their parents to explore the beneficial effects of participating in an intensive habilitation program on the child's adaptive functioning and parental empowerment in order to treat and reduce the consequences of early brain damage.
Rebion has developed a device, the Rebion trauma tool (referred to as the head and intraocular trauma tool, or "HITT"), that detects ocular fixation and alignment using a binocular retinal scan. Preliminary data obtained from hospitalized patients with a clinically-confirmed traumatic brain injury (TBI) and uninjured controls indicates that the device can detect changes in ocular fixation, alignment, and saccades that are related to brain injury. This study seeks to evaluate the ability of the Rebion trauma tool to assess perturbations in eye movements resulting from TBI. The study will enroll 100 TBI patients and 100 controls.

Throughout the course of the wars in Iraq and Afghanistan, more than 250,000 service members sustained traumatic brain injuries, mostly characterized as mild traumatic brain injuries (mTBI) or concussions. While most with mTBI recover over days to weeks, a significant percentage continue to experience post-concussive symptoms such as headaches, cognitive difficulties, and dizziness for months to years. As a result, treatment of post-concussive symptoms after mTBI is of significant importance in the Department of Defense and Veterans healthcare systems. Several studies have shown that cognitive rehabilitation can be effective for individuals with mTBI, including Service Members and Veterans with post concussive symptoms. Cognitive rehabilitation is a type of treatment in which patients work with a therapist to improve everyday memory and thinking skills and develop strategies to reduce the impact of cognitive difficulties in their everyday lives. While these treatments have great potential benefits, protocols studied to date are time intensive, requiring up to 60 hours of treatment. These time demands are impractical for many Service Members and Veterans, and place a time-burden on clinics providing the treatment. The current study proposes to identify key ingredients of an evidence-based cognitive rehabilitation protocol to develop a streamlined version that is feasible and acceptable to Service Members and Veterans. This briefer protocol will increase the number of Service Members and Veterans who can access treatment. To accomplish this goal the investigators will first spend six months analyzing manualized treatments from a successful cognitive rehabilitation intervention developed for Service Members. The investigators will analyze manuals using a framework developed to identify active ingredients in rehabilitation. Based on those results the investigators will develop a manualized streamlined treatment protocol, which the investigators will deliver to 25 Service Members and 50 Veterans over 18 months in person or via telehealth. The investigators will determine feasibility and acceptability of this intervention, and collect preliminary efficacy data. The project addresses access to therapy services and enhanced treatment compliance, a key barrier to participation in cognitive rehabilitation by Veterans and Service Members with TBI. Additionally, although this study focuses on Service Members and Veterans with mTBI, the investigators expect that this streamlined intervention can also be translated to civilian populations with mTBI.
Traumatic brain injury (TBI) is the leading cause of disability in children and young adults. Children with moderate to severe TBI are typically at risk of poor functional outcome in terms of neurocognitive impairment and behavior problems. Neurocognitive impairments include deficits in attention and working memory, learning and memory, and executive functioning, whereas behavior problems include anxiety, depression and aggression. Neuroimaging techniques based on multi-modal magnetic resonance image (MRI) can detect the structural and functional brain abnormalities objectively and sensitively. Recent evidence indicates that even after mild TBI, children with risk factors for intracranial pathology are at risk of poor neurocognitive and behavioral outcome.Meanwhile, recently, the concept of "gut-brain axis" has been proposed and hint gut microbiota could shape the brain. Some studies have emphasized that human gut microbiota plays an important role in the pathogenesis and development of TBI. However, how the gut affects the brain in patients with TBI is unclear. Thus, combining analysis of neuroimaging and "gut-brain axis" will provide more information for finding the risk factors and imaging diagnostic markers of brain impairment in TBI. It will also helpful for explaining the underlying mechanisms of brain impairment in TBI, providing an objective basis for clinical diagnosis and prediction of the prognosis.
This Randomized Controlled Trial (RCT) will explore the effect of sub-symptom threshold aerobic exercise on persistent post-concussion symptoms and exercise intolerance in patients with mild Traumatic Brain Injury (TBI). The hypothesis is that sub-symptom training will reduce the symptom pressure, normalize exercise tolerance, reduce patient-specific activity limitations and improve health-related quality of life. To improve the chances of conducting a high-quality RCT, a feasibility trial will be completed prior to the definitive RCT.
This study will look to validate predictive algorithms developed in a previous study where we collected relevant data from trauma registry and after using advanced signal-processing and machine-learning, determined prediction scores regarding neuroworsening and other outcomes following traumatic brain injury.
