The main purpose of this study is to compare patients with a deep bleed in the brain undergoing surgery to patients receiving routine medical care. The standard treatment involves admission to the Intensive Care Unit (ICU) with close monitoring and blood pressure control. It also includes other medical (non-surgical) treatments to prevent more bleeding or another stroke. Sometimes, doctors will recommend surgery to remove the blood if medical treatment alone is not successful. There is evidence that doing minimally invasive surgery early-using a small opening in the skull to remove blood-may help some patients. Researchers aim to understand whether this surgery is better than current medical treatment, which may include surgeries to relieve pressure on the brain in some cases. This study, called REACH, is comparing usual medical care to early minimally invasive surgery so doctors can know which is better for patients.
Early evidence suggests the benefits of post-stroke motor rehabilitation may be enhanced by applying electrical stimulation to the ear. This study aims to test the new approach of pairing ear stimulation with motor rehabilitation in the home setting in stroke survivors with upper limb motor function deficits.
The aim of this study is to compare the effectiveness of 6-weeks of reactive balance training (REACT) with and without neuromuscular electrical stimulation (NMES) to paretic lower limb muscles on biomechanical, clinical, neuromuscular and neuroplastic outcomes of reactive balance control. This project is a Phase-I study and incorporates a double-blinded, randomized controlled trial design. Methods: Forty-six individuals with chronic stroke will be recruited and screened for determining their eligibility for the study. Once enrolled, they will be randomized into either of the two groups: intervention group (23 participants) and control group (23 participants). Both groups will undergo series of pre-training assessments which includes a postural disturbance in the form of a slip- or trip-like perturbations and walking tests in laboratory environment. After the pre-training assessment, individuals will undergo 6-weeks of training (2 hour per session, 2 sessions per week). The intervention group will receive NMES with the REACT training and the control group will receive ShamNMES. NMES will be applied to the different muscle groups of the paretic lower limb using an advanced software which is able to synchronize muscle activation with the time of perturbation onset and according to the phases of gait. After training, both groups will again be tested on all the assessments performed pre training. This study will help us understand the immediate therapeutic and mechanistic effects of REACT+NMES and inform stroke rehabilitation research and clinical practice. Our study will provide foundational evidence for future use of NMES to implement clinically applicable neuromodulation adjuvants to reactive balance training, which could be leveraged for designing more effective future interventions for fall-risk reduction.
The purpose of this research is to better understand the impact of cortically-induced blindness (CB) and the compensatory strategies subjects with this condition may develop on naturalistic behaviors, specifically, driving. Using a novel Virtual Reality (VR) program, the researchers will gather data on steering behavior in a variety of simulated naturalistic environments. Through the combined use of computer vision, deep learning, and gaze-contingent manipulations of the visual field, this work will test the central hypothesis that changes to visually guided steering behaviors in CB are a consequence of changes to the visual sampling and processing of task-related motion information (i.e., optic flow).
The objective of this study is to evaluate the efficacy of the COOLSTAT® Transnasal Thermal Regulating Device in reducing temperature in a population of febrile subjects who meet the inclusion/exclusion criteria.
The purpose of this study is to evaluate the limb functional improvement after contralateral C7 root transfer in stroke patients.
People living with stroke have very low aerobic fitness, which can negatively impact brain health. Identifying the best exercise which includes exercise stimulus type (interval, continuous) or intensity, how hard to exercise (moderate, high) that benefit aerobic fitness, vascular health, and the brain's main blood vessels after stroke are unknown. This study is designed to determine the preliminary efficacy of high-volume HIIT to moderate intensity exercise using a seated stepper exercise device that allows the arms and legs to move back and forth.
VERIFY will validate biomarkers of upper extremity (UE) motor outcome in the acute ischemic stroke window for immediate use in clinical trials, and explore these biomarkers in acute intracerebral hemorrhage. VERIFY will create the first multicenter, large-scale, prospective dataset of clinical, transmagnetic stimulation (TMS), and MRI measures in the acute stroke time window.
The investigators aim to examine whether amantadine can help patients recover from stroke. This will be a blinded randomized clinical trial (RCT). Patients will be randomized post-ischemic or hemorrhagic stroke either to the placebo arm or amantadine arm. Patients will be on study drug or placebo for 1 month but will be enrolled for 3 months total. At various time points patients will be examined and fill out questionnaires to determine level of stroke recovery.
This innovative study will address scientific and clinical areas relatively unexplored in chronic stroke that could lead to greater recovery of walking. Ischemic Conditioning (IC) is a non-invasive, simple procedure that improves motor function, exercise performance and cardiovascular function in healthy controls, but it has never been applied to the stroke population. We postulate that IC enhances the recruitment of motoneurons and results in positive neural adaptations, improves vascular endothelial function and peripheral blood flow, and together these improvements result in an increased capacity to exercise and faster walking speed. Future studies will examine the effects of IC and traditional therapy at different time points of recovery post stroke, durability of IC, molecular mechanisms of neural and cardiovascular adaptation and the efficacy compared with other adjuncts.
