Filter by:The purpose of this study is to compare a 4-week, moderately intensive, lab and home-based aerobic exercise program versus exercise plus cognitive training. Participants will include individuals who experience lingering symptoms of a head injury or concussion.
This two-part study seeks to improve symptoms such as pain and sleep problems after concussion, or mild traumatic brain injury (mTBI). Study I evaluates symptoms of mTBI through a series of 10 office sessions in which musical tones are echoed, or mirrored back in real time, to reflect one's own brain activity. Those who take part in the study will be randomly assigned to receive either tones that are based on their brain activity/brainwaves, or random tones. Study II evaluates symptoms of mTBI through either 10 office sessions of the same acoustic stimulation linked to brain activity/brainwaves as Study I compared to 5 office sessions of acoustic stimulation plus intermittent very low level electrical stimulation of the scalp linked to brain activity.
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 objective of this study is to evaluate the efficacy of magnesium in symptomatic reduction of mild traumatic brain injury in the adolescent population in the acute setting of injury.
Investigators will measure cerebrovascular reactivity (CVR) using functional near-infrared spectroscopy (fNIRS) and magnetic resonance imaging (MRI) during the chronic phase after repetitive mild traumatic brain injury (rmTBI) as a biomarker of traumatic cerebrovascular injury (TCVI). We hypothesize that CVR will be decreased in patients with rmTBI and that these decreases will correlate with clinical outcomes. Furthermore, we predict that 5 week administration of a phosphodiesterase 5 (PDE5) inhibitor, sildenafil citrate, will augment CVR in patients with a history rmTBI.
Millions people, all over the world, are admitted in the Emergency Department after a trauma or simply to receive medical cares. In France, it represents 10 million patients. Probably because of stress associated with the event, 20% will suffer a combination of non-specifics symptoms which persist for many months and with daily life quality impairment. The investigators hypothesize that an early intervention, such as Eye-Movement, Desensitization and Reprocessing (EMDR) could be performed in the ED and could prevent the occurrence of these symptoms.
The study will ask the question as to whether or not it is possible to deliver education material to patients with a mild traumatic brain injury in a consistent matter. The question will be asked as to whether an educational intervention decreases symptom reporting specifically looking at headache symptoms. Half of the patients will receive the current standard of care in the tertiary clinic they have been referred to while the other half will also receive the current standard of care with the addition of targeted headache educational material at various time points.
Although the vast majority of individuals sustaining a sport-related concussion (SRC) will receive medical clearance to return to sport within 7-10 days, approximately 30% of children and adolescents reporting to the emergency department will experience symptoms that last longer than a month. Research has demonstrated that exercise below the threshold that results in increases in symptoms, beyond those experienced at rest, (sub-symptom threshold aerobic exercise) may be beneficial in recovery. However, the optimal amount and intensity of aerobic exercise for an individual to experience the most beneficial outcomes is currently unknown. Unfortunately there are limited Randomized Controlled Trials (RCT's) evaluating the benefits of aerobic exercise in a youth population. The current evidence includes studies with relatively small sample sizes, unreliable measurements of physical activity (self-report), and inherent biases through inadequate blinding. There is a need to develop and validate evidence-informed interventions as a means of treatment for limiting time loss from sport, and school in adolescents who experience persistent symptoms of sports related concussion beyond 10 days.
A concussion occurs when a person receives an impact to the head. The most common persistent symptoms that generate from a concussion are headaches, depression, lack of balance and dizziness. One recommendation to alleviate persistent symptoms of concussion is rest. Research findings indicate that the benefit of rest is inconclusive to help individuals suffering from a concussion return to activities of daily living. One treatment approach in reducing concussion symptoms is physical exercise therapy. Research findings, however, are limited to treatments being administered before the symptoms are considered persistent. Based on this rationale, the aim of this study is to examine the effect of a physical therapy intervention in minimizing persistent symptoms of concussion using measures of cognition and brain function, mental and physical health, and driving performance. If successful, this physical therapy intervention may help treat persistent concussion symptoms, improving the quality of life and ability for individuals to function normally in their daily lives, and resulting in savings to the healthcare system
This study evaluates the effect of binasal occlusion (BNO) glasses on balance and eye movement in adults with dizziness after a concussion. Participants will stand on a force plate while rapidly reading a series of numbers both with and without the BNO glasses. It is thought that the BNO glasses will improve both balance and the time to read the numbers.
