Filter by:Background: Memory consolidation is the process by which memories become stable, long-term representations in the brain. Consolidation of a motor skill is dependent upon sleep. Some research shows that daytime naps improve people s motor performance and memory retention. Researchers want to find out how daytime naps may contribute to learning and support consolidation of motor skill memories. Objective: To learn the role of memory replay during wakeful rest and sleep (naps) in retaining a newly learned skill. Eligibility: English-speaking adults ages 18 and older with chronic stroke, or healthy, right-handed, English-speaking adults ages 18-35 and 50-80 Design: Participants will be screened with: - medical history - neurological history - medicine review - medical exam - neurological exam. Participants will have a magnetic resonance imaging (MRI) scan of the brain. For this, they will lie down in a scanner. The scanner makes loud noises, so they will wear earplugs. They will fill out an MRI screening form before each MRI. Participants will also have magnetoencephalography (MEG). MEG maps brain activity. It does this by recording the magnetic fields produced by naturally occurring electrical currents in the brain. For MEG, participants will lie down in the MEG room. Their eye movements may be recorded by a video camera. Participants will have behavior testing. They will practice typing random keys. Then they will repeatedly type a custom sequence that they see on a computer screen. Then they will take a 2-hour nap. Then they will type the same sequence again. Participants will have no more than 4 visits at the NIH over 3 months. Visits will last 2-4 hours each.
This study is a prospective, open-label, multi-center, registry study, designed to to documents that EmboTrap II usage as a thrombectomy device for emergency large vessel occlusion (ELVO) in terms of the rate of First Pass Recanalization (FPR). Patients with ELVO will initially underwent mechanical thrombectomy usig EmboTrap II. FPR is defined as modified Tissue Thrombolysis In Cerebral Ischemia (mTICI) 2b or 3
Background: Virtual Reality (VR) technology may help to provide a way for stroke survivors to exercise in their own time at home, with remote clinical support. Before we introduce this technology we need to test that it will work alongside current health services for stroke survivors. Aims: To find out if using the MAGIC-GLASS solution alongside current healthcare care is usable and acceptable to stroke survivors and helps to increase rehabilitation time. Design: Measures before and after stroke survivors use the MAGIC-GLASS solution. Setting: Stroke survivors will use the MAGIC-GLASS solution in their own home. Population: adults (≥18 years) who have had a stroke at least two weeks before they enter into the study. Interventions: Our VR technology is called MAGIC-GLASS, and in order to use the solution the user puts on a headset which is connected to a computer. They can then see a VR environment in which they will be able to see virtual hands that respond to the movements of their own hands. It will also be possible to see a mirror image of their hands moving. The system will record how much they use the system and improvement in their movement. Regular contact will be made with a clinician who will be able to use the system to see (from their clinic) how the stroke survivor is doing and talk to them. Outcomes: We want to find out how the stroke survivors' movement changes over time and what they think of using the system. We will also ask clinical staff what they thought of using the system as part of healthcare provision to stroke survivors. Finally we want to find out how much it will cost to use the system.
Hemodialysis is a therapeutic strategy used in subjects with chronic renal failure. Our working hypothesis is based on results published in experimental animal models of stroke where the investigators have demonstrated that peritoneal dialysis is an effective technique to reduce blood glutamate levels and reduce infarct volume. The objective of this clinical trial is to evaluate the viability, safety and efficacy of hemodialysis in patients with acute ischemic stroke, proposing that it may have a) a potential neuroprotective effect by reducing the excitotoxic levels of glutamate and proinflammatory cytokines in blood and b) fewer technical problems than peritoneal dialysis to apply in usual clinical practice.
This study intends to use an dynamometer and surface electromyography to objectively and quantitatively measure the corresponding force and electromyography signal generated when the hand joint receives stretching by doing circular motion, and further explore the differences and relationships of existing muscle spasm classification, kinetic and kinematic data, upper extremity performance, activity of daily life. In addition, to investigate the differences of kinetic and kinematic data between stroke patient and healthy participants during doing hand circular motion activity.
The study aims to determine the added value of combining high-definition transcranial direct current stimulation (HD-tDCS) in a rehabilitation program based on virtual reality therapy (VRT) to potentiate the effects on neuroplasticity and further improve functional recovery of the arm in chronic stroke patients.
To investigate the prognostic value of Functional Near-Infrared Spectroscopy (fNIRS) in stroke rehabilitation with serial measurements.
The purpose of this study is to use Transcranial Magnetic Stimulation (TMS) while subjects are making reaching movements in a robotic arm device in order to discover how different brain areas control movement before and after stroke and when these brain areas are most sensitive to TMS.
The purpose of DEFENSE-ELDERLY is to identify the prevalence of AF and evaluate the clinical impact of AF in elderly ESUS patients and no other known sources of stroke besides a high-risk patent foramen ovale, and compare it with elderly ESUS patients without high-risk PFO (no PFO or non-high risk PFOs)
A single-site, interventional, single-arm trial to evaluate the safety and efficacy on functional mobility following Samsung GEMS-H (Gait Enhancing and Motivating System - Hip) device training in participants with sub-acute and chronic stroke.
