A Safety and Tolerability Study of Neural Stem Cells (NR1) in Subjects With Chronic Ischemic Subcortical...
Ischemic StrokeEvaluation of the safety and tolerability of escalating doses of NR1 administered intracerebrally at a single time-point post-injury to subjects with chronic ISS with or without cortical stroke.
Validation of a Brain-Computer Interface for Stroke Neurological Upper Limb Rehabilitation
StrokeIschemic1 moreThe study's main goal is to determine if clinical and physiological effects of a brain-computer interface intervention for the neurorehabilitation of stroke patients' upper limb are greater than the effects of a sham robotic feedback. For this purpose a randomized controlled trial will be performed to compare somatosensory sham robotic feedback with the same somatosensory feedback controlled with the brain-computer interface output.
Optimizing Training in Severe Post-Stroke Walking Impairment
StrokeChronic Stroke4 moreDifficulty walking is common after a stroke. Although physical rehabilitation helps a little with the improvement of walking ability, recovery is usually incomplete. The purpose of this study is to explore how two different treadmill training approaches influence walking speed, symmetry, and balance in people with chronic severe stroke-related walking impairment. The two approaches involve either forward or backwards treadmill training. This study will look at changes in walking performance and balance, before and after training. This study may lead to more efficient methods for improving walking performance and balance after stroke.
Neurofeedback Intervention for Reading Deficits in Subacute Stroke
StrokeDyslexia1 moreThe overall goal of this project is to advance a biologically-based approach to treatment of reading disorders after stroke, which will expand the limits of cognitive rehabilitation. Using a novel brain imaging technique, called real-time functional magnetic resonance imaging (fMRI) neurofeedback combined with right hand motor imagery, this project will re-instate brain activity in the left language-dominant hemisphere. Stroke patients will practice modulating their own brain activity using fMRI neurofeedback signal and will select the most effective mental strategies that help them maintain brain activation patterns associated with better reading recovery.
Use of Transmucosal Ketamine in Post Stroke Depression
Post-stroke DepressionStudies have shown that ketamine is very effective and has a quick onset in treatment of depression. Most of these studies used intravenous ketamine in an inpatient setting and there are no large trials examining its use in Post Stroke Depression (PSD). There have been only few studies that have used other routes of administration (i.e., oral, transmucosal, intranasal, intramuscular) of ketamine which provided symptom relief for depression. The purpose of this study is to assess the effectiveness and safety of use of transmucosal ketamine in treatment of PSD. We hypothesize that fast acting antidepressant effects can be achieved with tolerable side effects for translation into the general post-stroke population. To test our hypothesis, the specific aim is to: (1) demonstrate that transmucosal administration of ketamine is feasible within the post-stroke depression population and has tolerable side effects. Exploratory aims will include assessment if ketamine also produces fast acting antidepressant effects.
Regulating Blood Pressure During Recovery From Intracerebral Hemorrhage and Ischemic Stroke
Intracerebral HemorrhageIschemic Stroke1 moreThe purpose of this research study is to determine whether blood pressure treatment regimens with spironolactone are better than blood pressure treatment regimens without spironolactone at lowering blood pressure in stroke survivors.
Effects of Device-assisted Practice of ADL on Arm/Hand Recovery in Individuals With Moderate to...
StrokeA large number of post-stroke survivors cannot functionally use their paretic upper extremity (UE). This study therefore investigates effects of device-assisted practice of activities of daily living (ADL) in a close-to-normal pattern on UE motor recovery in individuals with moderate to severe stroke by measuring intervention-induced changes in clinical outcomes, UE kinematics, and functional and morphologic neuroplasticity. Positive findings may impact current clinical practice by pushing towards implementing device-assisted practice of ADLs and have the potential to benefit a large population.
Mesenchymal Stem Cells for The Treatment of Acute Ischemic Stroke
Acute Ischemic StrokeThe clinical study with UMC119-06 is designed to investigate the safety in patients with acute ischemic stroke ("AIS"). This will be a dose escalation, open-label, single-center study in adult with acute ischemic stroke. UMC119-06 is ex vivo cultured human umbilical cord tissue-derived mensenchymal stem cells product which is intended for treatment of acute ischemic stroke.
Effects of Mirror Therapy and Cognitive Therapeutic Exercise in Stroke Patients
StrokeHemiparesisThis is a randomized clinical trial aimed at patients with a diagnosis of residual hemiparesis due to ischemic or hemorrhagic stroke. Its objective is to evaluate the effects of the mirror therapy and cognitive therapeutic exercise, both in combination with task-oriented motor learning, to achieve maximum functionality of the affected upper member,
Non-invasive Vagus Nerve Stimulation in Acute Ischemic Stroke
Ischemic StrokeThe main objective of the study will be to investigate whether treatment with non-invasive vagus nerve stimulation (nVNS) on top of best medical practice in acute ischemic stroke patients results in less infarct growth in the penumbra and smaller infarct volumes compared with those of patients not treated with nVNS. The study will be a prospective randomized clinical trial with blinded outcome assessment (PROBE design). 150 patients will be randomized to nVNS with the gammaCore Sapphire™ device on top of best medical practice versus best medical practice alone (including intravenous thrombolysis and/or thrombectomy if indicated). If patients are randomized to nVNS, two stimulations of two minutes each will be applied in the neck every 15 minutes in the first 3 hours. Thereafter two stimulations will be applied every 8 hours over the next 5 days or until discharge, whichever occurs first. The stimulation side in the neck will be the radiological side of the stroke. The primary endpoint will be the final infarct volume on MRI scan on day 5 of patients treated with nVNS compared with those of patients not treated with VNS.
