Filter by:A large proportion of concussion patients with long-term consequences of concussion experience visually related symptoms such as headache, blurred vision, double vision, and fatigue. These patients often have difficulties coordinating the movement of the two eyes (convergence insufficiency) which is essential for single and clear vision to be obtained and is hence a likely explanation for the symptoms. 100 patients with long-term symptoms of concussion and convergence insufficiency will be offered either exercises or placebo treatment the evaluate the effect of exercises aimed at improving coordination between the two eyes. The study will provide data to support clinicians in deciding whether to use exercises or not as a treatment of symptoms for patients with convergence insufficiency as a long-term consequence of concussion.
In this study, the investigator plans a randomized trial of melatonin versus placebo post acute pediatric concussion. The investigator hypothesizes that patients with acute concussions managed with melatonin will have improved sleep, decreased depressive symptoms, decreased risk of prolonged concussion symptoms and faster resolution of concussion symptoms.
Approximately 1.9 million youth sustain a concussion each year, and up to 30% experience persistent post-concussive symptoms (PPCS) such as headache, dizziness, and difficulty focusing that continue for weeks or months. PPCS results in greater utilization of sub-specialty care and can impact immediate and long-term social development, cognitive function and academic success. Previous recommendations for treating PPCS have focused on cognitive and physical rest, but more recently guidelines have shifted based on new research suggesting the benefit of rehabilitative exercise for PPCS. The rationale behind using exercise to treat youth with concussion is that gradually increasing physical activity facilitates return to full function. Rehabilitative exercise has since become one of the most common approaches to treating youth with PPCS, but access is challenging since most programs require weekly centralized visits with a concussion specialist. To bridge this gap, the investigators developed a telehealth-delivered approach to treat PPCS, utilizing physical activity trackers (Fitbits) and weekly video conferences with trained research staff. They then conducted a series of pilot studies with this approach, finding excellent feasibility, acceptability, and evidence for more rapid declines in concussive symptoms compared to controls. The investigators also found preliminary evidence that mechanisms behind this intervention may stem from both physiologic processes due to increased moderate-to-vigorous physical activity (MVPA) and psychologic processes such as reducing fear- avoidance of concussive symptoms. They now propose a fully-powered randomized controlled trial (RCT) to asses the efficacy of the "Mobile Subthreshold Exercise Program" (M-STEP) for treating youth with PPCS.
The purpose of this study is to identify changes in salivary micro ribonucleic acid (miRNA) levels that are predictive of symptom duration and character following mild traumatic brain injury (mTBI) in children.
EEG signals have been collected and studied since the early 1990's as a way of assessing brain function at a gross level. As early as the 1930's a derivative of the raw EEG signal - event-related potentials (ERPs) - have been computed. The current research is primarily focused on three ERP components: the N100, P300 and N400. Each of the three ERPs have been studied in the academic laboratory for multiple decades. Through this research, a strong understanding has been developed regarding what can affect these components (e.g. task set, emotional state, etc.). However, these signals within various pediatric populations (e.g., those with persistent mTBI symptoms or multiple concussions) are not well characterized. Being able to safely and effectively employ the NeuroCatch™ Platform in a post-concussive pediatric cohort could provide researchers with the potential to elucidate the persistence of objective measures of impairment, patterns of recovery, and chronicity of problems due to mTBI in children. Secondly, understanding the degree to which these neurophysiological components fluctuate over time is crucial to the understanding of brain functioning. However, for this type of technology to be useful in quantifying brain health in this population,the degree to which a post-concussive pediatric brain naturally fluctuates in its processing capability must be quantified. NeuroCatch™ Platform has the ability to measure changes in several domains of brain function. These cognitive processes are foundational blocks for some of the highest cognitive processes: information integration and executive functioning.
The purpose of this randomized controlled trial is to examine whether systematic sub-threshold exercise is effective in improving recovery time in athletes after sport related concussion (SRC) compared to those who participate in a placebo/stretching protocol. subjects will be randomized into either an Exercise group or a Placebo/stretching group. subjects in the Exercise group will participate in an individualized exercise program supervised by their athletic trainer while the Placebo/stretching group will engage in a standardized stretching routine supervised by their athletic trainer throughout the duration of their recovery. Hypothesis 1: subjects in the aerobic Exercise group will require fewer days to recover from SRC than those who follow a placebo/stretching protocol. Hypothesis 2: heart rate threshold (HRt) achieved on the graded treadmill test will be associated with days to recovery (i.e., the lower the HRt, the longer the time to recovery). Hypothesis 3: Vestibular Ocular Motor Screen (VOMS) performance will be indicative of time to clinical recovery from concussion as evidenced by a strong correlation between VOMS score and days to clinical recovery. Hypothesis 4: Sub-threshold aerobic exercise will facilitate improvement in VOMS post-concussion. Hypothesis 5: subjects in the aerobic exercise group will demonstrate greater dynamic stability as evidenced by greater reach in each of the 3 primary directions (anterior, posterior medial and posterior lateral) for their right and left lower extremity.
