Filter by:The goal of this project is to test a new AAC-BCI device comparing gel and dry electrode headgear used for communication while providing clinical care. Innovative resources will be employed to support the standard of care without considering limitations based on service billing codes. Clinical services will include AAC assessment, AAC-BCI device and treatment to individuals with minimal movement due to amyotrophic lateral sclerosis (ALS), brain stem strokes, severe cerebral palsy, traumatic brain injury (TBI) and their family support person. This is a descriptive study designed to measure and monitor the communication performance of individuals using the AAC-BCI, any other AAC strategies, their user satisfaction and perceptions of communication effectiveness, and the satisfaction of the family support persons.
A proof-of-concept (POC) proposal to study the feasibility of customized head protection prototype device (HPPD) using 3D printed externally-applied moulded skin prosthesis integrated to the craniectomy bony skull defect.
The purpose of this study is to examine the validity of the Russian version of the FOUR Full Outline of UnResponsiveness (hereafter FOUR) scale in adult ICU patients with an acute cerebral insufficiency clinic (hereinafter referred to as OTSN). Compare the accuracy and predictive significance of FOUR when used by an ICU specialist, a neurologist, nursing staff, during bedside and telemedicine Examinations.
Objective: To determine whether immersive virtual reality (VR) treatment interventions improve executive dysfunction and complex attention deficits in patients with brain injury compared with standard neurorehabilitation, and whether VR performance predicts neurorehabilitation outcomes at discharge. Design: Mixed design study with quasi-experimental Intervention group (N = 12) and retrospective Control group (N = 12). Both groups were compromised of individuals with brain injury admitted to an outpatient day neurorehabilitation program.
This study evaluates the addition of therapy dogs in inpatient physical and occupational therapy. Data will be collected across 10 PT and 10 OT sessions, half of which will incorporate a therapy dog.
Increase in intracranial pressure (ICP) could be associated with increase in positive end-expiratory pressure (PEEP) level. Data are however disparate and interactions between ventilation with high PEEP and intracranial circulation are still debated. Individual patient's chest wall elastance could have a key role in determining the effects of PEEP on ICP, since it dictates which proportion of the applied PEEP is transmitted to the pleural space, thus increasing central venous pressure (CVP) and reducing cerebral venous return. Measurement of esophageal pressure with a dedicated probe allows partitioning of respiratory system elastance into its lung and chest wall components, thus permitting to study this phenomenon. Multimodal intracranial monitoring permits to study the effects of PEEP on more advanced brain-specific indices such as brain tissue oxygen (PtiO2), cerebral microdialysis data, transcranial doppler ultrasound-derived flow measurements and automated pupillometry, besides ICP. This study aims to test the association between the ratio of chest wall to respiratory system elastance and PEEP-induced variations in ICP and brain-specific multimodal monitoring indices. This study will evaluate the relative role of other selected measures of respiratory mechanics, hemodynamic variables and intracranial compliance, in order to establish the role of individual respiratory mechanics in the interplay of physiological factors affecting the effects of positive pressure ventilation on the brain. Patients will undergo two periods of ventilation at two different levels of PEEP (5 and 15 cmH2O) in a randomized cross-over order. At the end of each period, cardiorespiratory clinical data, ICP and other advanced multimodal neuromonitoring data (brain tissue oxygen tension, cerebral microdyalisis analytes, transcranial doppler ultrasound and automated infrared pupillometry data) will be collected. Systematic respiratory mechanics assessment (including calculation of chest wall and lung elastances and estimation of the amount of recruitment versus overdistension due to PEEP by means of a single-breath derecruitment trial), echocardiography and arterial blood gas analysis will be performed.
This pilot study is designed to provide preliminary data for a large scale, randomized clinical trial to evaluate the efficacy of remotely administrated at home transcranial Direct Current Stimulation (tDCS) with real-time monitoring via VA Tele-health for persistent post traumatic headache associated with mild traumatic brain injury (mTBI). Participants will receive total of 20 sessions of tDCS over four weeks. The investigators anticipate that the results generated from the study will directly translate into immediate meaningful clinical application: not only in management of chronic post traumatic headache, but also in reduction of acute pain medication use, and improving quality of life for our veterans with this debilitating neurological disorder.
Hypothesis 1: On fMRI scanning, frontoparietal activation during performance of executive function tasks of working memory, inhibitory control processes, and stimulus-response interference will exhibit greater signal intensity, a wider spatial extent, and more bilateral activation in chronic MTBI than chronic OI participants. Hypothesis 2: DTI changes, characterized by lower FA and higher MD at the gray-white junction, corpus callosum, central semiovale, and internal capsule, will be seen in MTBI but not in OI subjects. Hypothesis 3: Increased fMRI activation in chronic MTBI will be correlated with location and severity of disrupted fiber tracks that subserve neural networks associated with each fMRI activation task. Hypothesis 4: Performance on computerized neuropsychological testing (ANAM) and reaction time measures on fMRI tasks will better discriminate MTBI from OI than standard paper-and pencil tests. Hypothesis 5: The combination of fMRI, DTI, and ANAM will better discriminate MTBI from OI than each individual method. Hypothesis 6: More severe brain pathology in MTBI, as measured by neuroimaging (fMRI, DTI) and ANAM test scores, will be associated with less severe PTSD and symptoms.
Working memory is a limited capacity cognitive system in which information is held temporarily in order to make it available for processing. The amount of information that can be held in mind varies considerably from person to person and changes across the lifespan. Working memory is frequently affected following brain injury. As working memory is important for cognitive skills such as problem solving, planning and active listening, a deficit in working memory can lead to difficulties with many everyday activities that are necessary for work, study and general functioning. Impaired working memory may consequently have a significant impact on a person's quality of life and ability to participate in previous social roles, with potential for effects on mood and emotional wellbeing. Evidence shows that non-invasive transcranial direct current brain stimulation (tDCS) can be used in combination with computerized memory training (CT) over multiple days, to enhance working memory in healthy and clinical populations. In patients with an acquired brain injury (ABI), cognitive training or brain stimulation have been used alone to improve attention or memory-related impairment, but the effect of the concurrent used of the two interventions over multiple days is yet to be investigated. With this research the investigators propose to investigate the effect of the combined use of tDCS and CT to improve memory performance in patients with acquired brain injury. The investigators propose to use a multi-day cognitive training regime to exercise working memory, while stimulating the brain with low intensity direct currents. Success will be measured as improvement in performance in several cognitive domain, before and after training.
