Filter by:This study aims to determine the validity and safety of disparity driven vergence using a portable goggle system (I-PAS) using a pseudorandom ternary sequence of frequencies for testing.
This study aims to investigate the efficacy and tolerability of fMRI-targeted repetitive transcranial magnetic stimulation (rTMS) in the treatment of depressive symptoms in service members with a history of concussive traumatic brain injury (TBI). Up to ninety participants will be randomized to active or sham treatment. Participants randomized into the active group will receive 20 sessions of left-sided dorsolateral prefrontal cortex (DLFPC) high-frequency rTMS, followed by right-sided DLFPC low-frequency rTMS. The DLPFC treatment area will be identified by using individual subject-level resting state network estimation (Hacker et al., 2013). Participants randomized into the sham treatment group will receive 20 sham treatments designed to have similar sound and tactile sensation, without producing active treatment. Participants will also be asked to complete regular follow-up evaluations for up to a total of six follow-up sessions. Those who do not respond to the treatment will have the option to receive active treatment through this study regardless of group assignment to active or sham.
Study will test the use of a short virtual reality driven goggle test as a means of detecting mTBI in a diverse group of athletes
This study is being conducted to quantify the clinical safety and efficacy of head and neck cooling when applied up to 8 days after mild traumatic brain injury (mTBI) among adolescents participating in sporting activities.
Children and youth are at a greater risk of concussions than adults, and once injured, take longer to recover. The increased incidence of sports-related concussion in youth and the potentially serious long-term negative impact on their developing brains has enormous repercussions. While most young athletes recover within several days, many continue to experience symptoms for many months post-concussion. Symptoms are wide ranging and include - most notably: headache, sleep disturbances, brain fog, irritability as well as impairments in emotion and cognitive function (i.e. attention, memory, concentration, etc.). Yet there are no evidence-based intervention studies that have successfully addressed these symptoms. Thus, there is an urgent need for improved therapeutic strategies, which promote optimal functional recovery in youth concussion. Transcranial direct current stimulation (tDCS) is a safe, non-invasive neurostimulation technique that can modulate neural excitability in the brain to positively impact cognition, behaviour and mood, particularly when combined with a behavioural intervention. Our long-term goal is to determine whether exercise combined with neurostimulation improves recovery from concussion. However, to our knowledge, the therapeutic potential of tDCS has not been studied in youth with concussion. Our objectives are as follows: 1. To determine the tolerability of a 20-minute session of tDCS in symptomatic youth athletes; 2. To evaluate the association between symptoms and EEG metrics at baseline and following a single session of tDCS in symptomatic athletes and compare these associations in symptomatic athletes who do not receive tDCS.
Every year 1.7 million people sustain a traumatic brain injury (TBI) in the United States and of these, 84 % are considered mild TBI (mTBI). mTBI is common both in civilian and military populations and can be debilitating if symptoms do not resolve after injury. Balance problems are one of the most common complaints after sustaining a mTBI and often prevent individuals from returning to their previous quality of life. However, the investigators currently lack clear guidelines on when to initiate physical therapy rehabilitation and it is unclear if early physical therapy is beneficial. The investigators believe that the underlying problem of imbalance results from damage to parts of the brain responsible for interpreting sensory information for balance control. The investigators hypothesize that retraining the brain early, as opposed to months after injury, to correctly interpret sensory information will improve recovery. The investigators also believe this retraining is limited when rehabilitation exercises are performed incorrectly, and that performance feedback from wearable sensors, can improve balance rehabilitation. There are three objectives of this study: 1) to determine how the timing of rehabilitation affects outcomes after mTBI; 2) to determine if home monitoring of balance exercises using wearable sensors improves outcomes; and 3) to develop a novel feedback system using wearable sensors to provide the physical therapist information, in real-time during training, about quality of head and trunk movements during prescribed exercises. The findings from this research could be very readily adopted into military protocols for post-mTBI care and have the potential to produce better balance rehabilitation and quality of life for mTBI patients and their families.
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.
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.
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.
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.
