Filter by:The purpose of this study is to investigate the efficacy, safety, and tolerability of two dorsolateral prefrontal cortex (DLPFC) repetitive transcranial magnetic stimulation (rTMS) protocols to alleviate symptoms of depression in United States (U.S.) military service members and veterans with a history of concussion/mild traumatic brain injury (TBI).
Concussions are consequences of inopportune interactions between an impact force and the head that causes the head (and brain) to move too rapidly. This project involves two parts. 1. The outcome of head-impact depends upon the force and the biomechanical properties of the head-and-neck. Modern microelectrical mechanical systems (MEMS) head-impact sensors only measure the physical parameters of external forces. The researchers have developed a next-generation smart MEMS sensor fortified with artificial intelligence (AI) that can help define a personalized concussive threshold. The researchers sensor machine-learns the biomechanical properties of the participant's head-and-neck and accurately determines the likelihood for concussive injuries. The researchers first goal is to field-test the sensor in soccer players. 2. Researchers hypothesize that an increase in neck stiffness should reduce concussive risks. The researchers have developed a training protocol that involves a conditioned response (CR) to increase neck stiffness during a head-impact event and thereby decrease concussion risk. The Researchers have also developed technology to monitor neck stiffness. The smart sensor is fully integrated into the training protocol and monitors the neck stiffness to validate the effectiveness of the training. The second goal is to optimize and finalize our training protocol and conduct a field-test in soccer players.
The ICONICC Study is a randomized controlled clinical trial designed to compare the proportion of successful treatment outcomes between children assigned to standard concussion care only, standard concussion care plus simple convergence procedures, or standard concussion care plus office-based vergence/accommodative therapy in children aged 11 to 17 years with symptomatic post-concussion syndrome. Children with post-concussion syndrome (4-12 weeks post-concussion injury) and symptomatic CI will be randomized to a 12-week treatment program of either standard concussion care (SC), SC plus simple convergence procedures (SC+), or SC plus office-based vergence/accommodative therapy SC+OBVAT (1:1:1 ratio). The study will also compare the effect of treatment on clinical measures of both accommodation and vergence, symptom level/burden, health-related quality of life, clinical measures of saccadic eye movement, and objective eye movement measurements of disparity vergence, saccadic function, and accommodative function. The attainment of objective eye movement measures provides an opportunity to understand the underlying neurophysiology of the vergence and accommodative systems. Objective eye movement recordings are powerful because of the rich foundation from primate single-cell recordings that show a direct correlation with vergence and accommodative parameters in the supraoculomotor area of midbrain2, 3 and the oculomotor vermis of the cerebellum.4, 5 Thus, a combined approach of acquiring both clinical vision function measures and objective eye movement recordings in children with PCS-CI may lead to better characterization of the oculomotor phenotype with subsequent improved and personalized therapeutic interventions.
Sport concussions are among the most commonly occurring injuries in sport and recreation and pose significant public health implications for Canadians. Many individuals who sustain a concussion recover in the initial 7-10 days but up to 74% of youth and 31% of adults may suffer from persistent symptoms. Little research is currently available evaluating the effects of treatment for individuals who are slower to recover following sport-related concussion. An initial RCT identified a significant treatment effect in individuals with persistent symptoms of dizziness, neck pain and/or headaches following sport-related concussion when treated with a combination of cervical and vestibular physiotherapy compared to a typical protocol of rest followed by graded exertion (Schneider et al, 2014). Low level aerobic exercise in combination with sport specific training may also be of benefit to facilitate recovery in children and youth following concussion (Gagnon et al, 2009, 2016). Further evaluation of these treatments is required to better understand the effects of each treatment in isolation and in combination. This trial will have the ability to inform future multifaceted clinical trials as well as clinical practice. Ultimately, identification of optimal treatment paradigms will lead to a decrease in persistent symptoms and functional alterations in children and youth from this commonly occurring injury.
In the past 20 years, the incidence of concussion in direct contact sports has significantly increased. The incidence of concussion in rugby players ranges between 8 to 17 episodes / 1000 playing hours. A recent study published by the French Rugby Federation (FFR) and the National Rugby League (LNR) showed similar results. The latter study was performed analyzing the French "TOP14", which includes 14 teams participating in professional rugby championships. At least two concussions were diagnosed each week. Despite the recent evidence, cognitive assessment remains the only means to determine whether or not players experiencing concussions can return to the game or not.
