Filter by:The purpose of this study is to develop a diagnostic algorithm to help with the detection, diagnosis, and monitoring of sub-concussive head impacts.
The main hypothesis is that exposure to repeated shocks is associated with a greater decrease in the thickness of optical nerve fibres. In order to show a association between the occurrence of concussions (in number and severity) and the variation in the thickness of the retinal nerve fibre layer, all participating rugby players will have an ophthalmologic examination (OCT and (retinophotography) at the beginning and end of the Rugby season.
The purpose of this study is to establish the tolerability of mindfulness and yoga therapy in the post-concussion period.
Approximately 15-20% of patients diagnosed with a concussion/mild traumatic brain injury (mTBI) have persistent symptoms that continue up to six months or longer. Typical problems identified by these patients include difficulty with memory, multi-tasking, the ability to complete tasks quickly, and higher executive functions (e.g., inhibition, initiation, insight, motivation) (Belanger & Vanderploeg, 2005; Mott, McConnon, & Rieger, 2012, Rabinowitz & Levin, 2014). If these symptoms persist they can not only affect thinking, but also communication abilities (e.g., verbal and nonverbal interactions, reading, and writing) (ASHA, 2007). Therefore, it is hypothesized that screening measures that evaluate both thinking and communication can better identify individuals at-risk for persistent symptoms at two week and four weeks post-injury. Also, if cognitive-communication therapy was administered earlier post-injury, then outcomes related to return to daily activities, work, and/or the academic setting could possibly change. This study intends to investigate the use of cognitive and communication screening measures for the identification of persistent symptoms and the provision of early cognitive-communication therapy if problems persist.
This study is part of a larger, multi-centered project done with the collaboration of University Of Victoria. This study holds three separate studies on the mild traumatic brain injured population and the use of perceptual-cognitive training (3D-MOT).
This will be a prospective study of the implementation of a real-time assessment and intervention of a text messaging tool in mild traumatic brain injury (mTBI) patients post-discharge from the emergency department.
Significant morbidity, mortality, and related costs are caused by traumatic brain injury (TBI). A simple, effective, and lightweight device worn by athletes or war fighters in the field, designed to mitigate TBI resulting from blast trauma or concussive events, would save lives, and the huge costs currently being experienced for life-treatment of surviving victims. An externally-worn medical device that applies mild jugular compression according to the principle of the Queckenstedt Maneuver. PURPOSE: To monitor changes in vital signs, blood physiologies, oxygen consumption, biomechanics, strength, neurological capabilities, and balance in a population of athletes wearing the Device. Secondly, to determine the tolerance and acceptance of the Device while undergoing exertion.
Adolescents with concussion will be randomly assigned to a treatment group where they will receive sub-threshold exercise, or assigned to a placebo group where they will receive structured stretching exercises. Both groups will receive standard medical coverage with regular clinic visits. All participants will record symptoms daily on a dedicated web site. All participants will be evaluated at time 1 with (1) structured physical exam, and (2) structured exercise stress test which is terminated when there is symptom exacerbation. The primary outcome measure is time to recovery where recovery is defined as (1) asymptomatic for two consecutive days, and (2) ability to exercise to exhaustion without exacerbation of symptoms, and (3) confirmed by a physician based on a structured physical exam.
Significant morbidity, mortality, and related costs are caused by traumatic brain injury (TBI). An externally-worn medical device that applies mild jugular compression according to the principle of the Queckenstedt Maneuver (the Device). Preliminary research suggests that the Device has the potential to reduce the likelihood of TBI. The currently developed collar has been approved for studies in humans and the results indicate safety for use during high demand and maximal exertion activities, This study will investigate the effectiveness of this device in high school athletes playing a collision sport such as football. The use of helmets during such a high-risk sport will allow for collision measurement devices to be embedded in the helmet and will not affect play or fit of equipment. Athletes participating in this study will be randomly assigned to one of two groups: 1) Device wearing during the season or 2) Non-device wearing during the season. The helmets of all participants will be outfitted with an accelerometer which will measure the magnitude of every impact to the head sustained by the athlete. Effectiveness of the device will be determined via differences in longitudinal brain imaging and functional testing following competitive football participation. A subset of athletes who report a diagnosed concussion will also receive additional brain neuroanatomical and neurophysiological testing within a week following the diagnosed concussive event. The purpose of the study is to monitor longitudinal changes in brain structure and function between the preseason and postseason, in a population of football playing athletes wearing the Device and compared to a similar population not wearing the device. Secondly, the purpose is to determine the protection of the device relative to amount and magnitude of sustained head impacts.
A post-concussion syndrome (PCS) diagnosis has historically led to a recommendation of continued mental and physical rest to minimize symptoms. However, this conservative approach does not consider the pathophysiological mechanisms and neurological subsystem dysfunction which mediate persistent signs and symptoms. Recently, developing research is recommending targeted therapies for specific post-concussion disorders (physiologic, vestibulo-ocular and cervicogenic). The Buffalo Concussion Treadmill Test (BCTT) is a graded aerobic test that has emerged as safe, reliable, and effective in distinguishing between post-concussion syndrome sub-types, quantifying physiological recovery, and guiding return to play decision making. It has been proposed that the results of a BCTT can be used to prescribe progressively intensifying whole body aerobic exercise (such as walking or biking), maintained at a sub-symptom threshold, to improve autoregulatory function with the potential to improve PCS symptoms. Positive results with BCTT have now made it the standard of care at the University of Buffalo Concussion Clinic and Pan Am Clinic during the management of sport related concussions. Despite its increased use in patients with post-concussion syndrome there is currently no data on the use of exercise treatment in the early stages of concussion recovery.
