Filter by:The purpose of this study is to determine if the pulse pressure changes are different whether patients are training in a traditional tilt table as compared to a robotic assisted tilt table, which induces leg movement.
The purpose of this research study is to investigate how useful three balance tests are in predicting fall risk in the individual with traumatic brain injury (TBI). These tests are the Functional Gait Assessment (FGA), the Berg Balance Scale (BBS), and the mini-Balance Evaluation Systems Test (mini-BESTest).
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.
The primary purpose of this research is to increase adherence to outpatient rehabilitation of chronically underserved individuals with traumatic brain injury (TBI). The intervention will be a TBI rehabilitation-focused education tool suitable for use with a wide variety of patients, including those with poor literacy skills and those with Limited English Proficiency (LEP), hereafter referred to as the Multimedia Multicultural Educational Program for TBI (MMEPT).
The main objective of this study is to examine the effect of Goal Management Training for patients with executive difficulties after acquired brain injury in a randomized controlled trial. The effect on cognitive functioning will be examined, as will the relationship between treatment effects and lesion location and size. The effect of Goal Management training on regulating emotions, quality of life and coping will be examined. The generalizability of treatment effects across etiologies will be explored by comparing effects in three patient groups; traumatic brain injury, cerebrovascular accidents and resected brain tumors. Structural Magnetic Resonance Imaging (MRI) scans and measures of white matter connectivity will be used to establish detailed lesion descriptions. Functional MRI data will provide information on the neural underpinnings of treatment related change. A secondary objective is to expand the Goal Management Training protocol with increased focus on emotional regulation and adherence to homework assignment.
The purpose of this open trial is to investigate the feasibility, acceptability, and effect of metacognitive therapy in patients with prolonged post-concussive symptoms after mild traumatic brain injury.
Traumatic brain injury (TBI) is the leading cause of death or disability in children. Each year in the United States, pediatric TBI results in an estimated 630,000 emergency room visits, 58,900 hospitalizations, and 7000 deaths. The incidence of long-term disability after severe TBI is high, with over 60% of children requiring educational or community based supportive services 12 months post-injury. Over 5,000 children require inpatient rehabilitation after TBI each year and an estimated 145,000 US children are currently living with disabilities after a severe TBI. Hospital costs for the acute treatment of children with TBI are estimated at ~$2.6 billion each year, while the gross annual costs accounting for long-term care and lost productivity approach $60 billion. Therefore, pediatric TBI is a major public health concern and new ways to diagnose and treat TBI are urgently needed.
The study will be conducted over 18 months. The main objective of this study is to explore the relationships between autobiographical memory and specific cognitive measures, as well as emotional and behavioural measures in patients who have suffered a moderate to severe TBI. Secondary objectives are to assess the psychometric properties of a self-defining memories questionnaire and to characterize autobiographical memory in the TBI population.
There are concerns that the use of positive end-expiratory pressure (PEEP) for the treatment of pulmonary complications in patients with brain injury may potentially elevate intracranial pressure (ICP), and deteriorate neurological status. It is suggested that both respiratory system compliance and ventricular compliance would contribute to the elevation of ICP when PEEP increases. In theory, PEEP may cause elevation of ICP by increasing intrathoracic pressure and diminish venous return. However, the transmission of PEEP into thoracic cavity depends on the properties of the lung and chest wall. Experimental study showed that when chest wall compliance is low, PEEP can significantly increases intrathoracic pressure; whereas low lung compliance can minimize airway pressure transmission. It is generally recognized that the lung compliance decreases in acute respiratory distress syndrome (ARDS) patients due to extensive alveolar collapse. However, it has been report that the elastance ratio (the ratio between elastance of the chest wall and the respiratory system, where elastance is the reciprocal of compliance) may vary from 0.2 to 0.8. Therefore, it is important to distinguish the compliance of the chest wall and the lung when investigating the effect of PEEP on ICP. Because intrathoracic pressure (pleural pressure) is difficult to measure in clinical situations, esophageal pressure (Pes) is considered as a surrogate of intrathoracic pressure. In the present study, the investigators determine the effect of PEEP on intrathoracic pressure and ICP by Pes measurement.
This study (Part 2) is designed to build a database including EEG, neurocognitive performance, clinical symptoms, history and other relevant data, which will be used to derive a multimodal EEG based algorithm for the identification of concussion and tracking of recovery. In addition, neuroimaging will be conducted at time of injury and following Return to Play (RTP).
