The CRS-R is a standardized and validated bedside assessment of conscious awareness. It is used routinely for diagnosis and prognosis of patients with disorders of consciousness (DOC) as well as in research settings. One limitation of the CRS-R is the lengthy administration time required to obtain a total score. Administration time can vary from approximately 15-30 minutes, depending on the patient's level of responsiveness. For this reason, the CRS-R is rarely administered in the acute hospital setting. Less time-consuming scales and metrics are used to assess conscious awareness in the acute hospital/ICU setting, but they lack specificity and sensitivity and have not been validated, increasing the potential for misdiagnosis. In conjunction with the developers of the Neuroscore (an unpublished, abbreviated version of the CRS-R), we have developed the CRSR-FAST and aim to test its validity, inter- and intra- rater reliability. We anticipate that, compared with the CRS-R, the CRSR-FAST will be less time-consuming to administer and score, but will maintain a high level of sensitivity to detecting signs of consciousness in severely brain injured patients.
The purpose of this research study is to test whether a portable goggle system (I-PAS) is good at diagnosing mild traumatic brain injury (mTBI) in a community setting. The goal is to determine whether the IPAS goggle system can be used reliably in an urgent care or emergency department setting.
Many patients suffer from a topographical disorientation after a traumatic brain injury. Virtual Reality settings allow us to develop navigational cues, in order to rehabilitate patients or to help them in daily life. Some visual and auditory cues have proved efficient in helping patients navigating in a virtual environment but when administered separately, they never enabled patients to obtain a similar navigation performance as healthy controls. Moreover, the effect of the combination between visual and auditory cues has never been studied before. The objective of the present study is to determine if the combination between visual and auditory cues improve spatial navigation and memory of patients with a traumatic brain injury. Therefore, the investigators intend to include in this prospective randomized study 45 patients who have had a moderate or severe traumatic brain injury and 20 healthy controls. Participants will have to reproduce actively with a joystick three different paths including 6 intersections that they have previously seen on a computer screen. One path will be done without cues, one with visual or auditory cues, and one with combined cues (visual+auditory). The order of the paths will be randomized. Auditory cues consist of beeping sounds indicating the direction at each intersection. Visual cues consist of salient landmarks (red and blinking) positioning at each intersection. The main judgment criterion will be the number of trajectory mistakes during the path reproduction (/6). The secondary judgment criteria will be : time of navigation, memory of the landmarks, the route and the survey of the virtual environment. The confirmation of the help given by the combined cues could further allow the patients to use them in rehabilitation or in real life using augmented reality.
The aim of this study is to assess the brain correlates, as assessed with multimodal MRI, of working memory training in patients with severe traumatic brain injury (TBI)
The long term goal for the Traumatic Injury Research Program (TIRP) is testing of novel devices for the identification and longitudinal assessment of traumatic brain injury (TBI). DoD (United States Department of Defense) has now tasked TIRP with the test and evaluation of these devices to assess reliability and validity. The objective of this effort is to test the reliability of the NKI, Inc, (NeuroKinetics, Inc) i-PAS device using a test/re-test protocol with healthy controls. The research design is test/re-test, with three assessments obtained on three separate visits. This will allow the assessment of reliability of both the device and the measure(s) that are computed from the input signals. Participants will be Healthy Controls (HC) as defined in the inclusion exclusion section. In this initial study, investigators will be administering standardized self-report instruments (Standard Form 36 - SF36, and Symptom Checklist 90r, or SCL-90r), standard three-lead EKG. In addition they will administer the NKI i-PAS specific protocol as delineated by NKI.
The goal of this study is to establish that a memory retraining protocol, originally developed for English-speakers, and translated into Spanish, is effective.
The purpose of this study is to examine the effects of exercise on recovery after traumatic brain injury. Investigators will determine if exercise enhances rehabilitation by increasing substances (proteins) that can facilitate recovery.
Investigators will determine the long-lasting effects of post-acute rehabilitation after traumatic brain injury and stroke. Investigators will also evaluate if the beneficial effects of rehabilitation continue after discharge from a rehabilitative program.
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.
