Filter by:The purpose of this study is to understand the physiology of connectivity between cortical regions in the human brain in healthy participants and in patients with white matter lesions. Specifically, the investigators will examine the effects of paired associative stimulation (PAS) which consists in delivering brief (< 1 ms) current pulses separated by a short millisecond-level time interval ("asynchrony") to two cortical areas. The used techniques are all non-invasive and considered safe in humans: transcranial magnetic stimulation (TMS), electroencephalography (EEG), magnetic resonance imaging (MRI), and functional MRI (fMRI). Based on prior literature in animals and human studies, it is hypothesized that PAS may increase or decrease effective connectivity between the stimulated areas depending on the asynchrony value. The main outcome measure is source-resolved EEG responses evoked by single-pulse TMS; this is a more direct measure of neuronal changes occurring at the targeted cortical area than motor evoked potentials (MEPs) or sensor-level EEG responses used in previous studies.
Intracranial pressure (ICP) is defined as the pressure inside the skull, and therefore, the pressure inside the brain tissue and the cerebrospinal fluid (CSF). The relationship between CSF and intracranial blood volumes is described by the Monroe Kellie doctrine; because the brain is incompressible, when the skull is intact, the sum of the volumes of brain, CSF, and intracranial blood is constant.
Traumatic Brain Injury (TBI) is a prevalent disorder developed by military personnel. While some individuals recover function within months after injury, others continue to suffer from cognitive problems months to years later and may not become evident immediately, particularly for the recently transitioned veteran. Chronic TBI cases may include persistent difficulties in cognition that negatively impact employment and personal relationships. The investigators will test and evaluate software-based interventions aimed at improving cognition in veterans experiencing everyday life cognitive deficits due to TBI. The interventions will be administered on a computer using a tele-health approach. Two conditions will be compared, an active condition challenging memory, inhibitory control and planning, and a context-matched control condition that is lower on these challenge levels.
Using a prospective cohort of children admitted to the PICU, the investigators will determine HRV monitoring is feasible, if a decreased HRV in the 7 days following moderate or severe TBI in children is associated with a worse outcome 6 months post-TBI and investigate HRV as a tool that can predict adverse events (neurological crisis) within 2 days following TBI.
This study aims to explore if a yoga-based physical therapy session would promote improved (increased) heart rate variability in subjects with traumatic brain injuries. The results of this pilot study may inform a larger-scale study of the effects of regular participation in a yoga-based program as an adjunct to traditional physical therapy. The secondary objective is to determine whether a yoga-based physical therapy session would impact anxiety, fatigue, or agitation and/or sleep quality. The study will enroll up to 30 inpatient subjects on a rolling basis as they are admitted with traumatic brain injury over a 12 month period at the Shirley Ryan AbilityLab. Each person in the study will participate in three conditions in a random order across three days: 1 hour of yoga-based physical therapy session in a group setting,1 hour of one-on-one conventional physical therapy, and 1 hour of seated rest in a relaxing environment in a group setting. The hypothesis is that individuals who participate in 1 hour of a yoga-based physical therapy session in a group setting will demonstrate a significant improvement in heart rate variability, anxiety, fatigue, and agitation after the session when compared to the same measures after 1 hour of a conventional physical therapy session and 1 hour of seated rest in a relaxing environment. Sleep will also be assessed with an activity monitor.

A systolic blood pressure (SBP) lower than the heart rate (HR) could indicate a poor condition in trauma patients. In such scenarios, the reversed shock index (RSI) is <1, as calculated by the SBP divided by the HR. This study aimed to clarify whether RSI could be used to identify high-risk adult patients with isolated traumatic brain injury (TBI).
The main objective of this study is to evaluate the effects of tRNS while undergoing computerized cognitive rehabilitation therapy to conclude if this combination of therapies would be effective for the cognitive rehabilitation of patients with acquired brain damage, such as traumatic brain injury. We want to study the therapeutic potential of tRNS to enhance the therapeutic outcome of cognitive training, studying its global effect over the rehabilitation of attention, memory and executive functions, compared to sham tRNS.
The purpose of this project is to provide a new framework for diagnosing and monitoring treatment of light sensitivity and headache by objective measurement of facial features, pupil responses, retinal electrical responses and autonomic nerve responses to light.
