Active clinical trials for "Stroke"

A Phase 3 study to examine the safety and effectiveness of the allogeneic, adult stem cell investigational product, MultiStem, in adults who have suffered an acute ischemic stroke in the previous 18-36 hours.

This study evaluates whether a 4-week exercise training program focusing on lower limb flexors can improve lower limb motor function late after stroke. It is hypothesized that there would be significant improvements in gait and strength of the flexor muscles as a result of the training. It is also hypothesized that the training effects, if any, would be retained at 4 weeks after ending the training.

Stroke affects upwards of 800,000 Americans every year and has an enormous impact on the well-being of the American Veteran population with 6,000 new stroke admissions every year. Many of these stroke survivors are living with walking disabilities. Gait problems result in inability to function independently, high risk of falls and poor quality of life. Unfortunately, current gait rehabilitation treatments are limited and many stroke survivors do not achieve full recovery. Therefore, it is critical to develop new approaches to enhance gait rehabilitation methods. The investigators propose to evaluate a brain stimulation treatment called transcranial Direct Current Stimulation (tDCS) that can be added to physical therapy. tDCS has been applied for arm rehabilitation after stroke with positive results, but gait-related investigations are lacking. The investigators will test whether simultaneous tDCS and gait training produces greater improvement in walking abilities than gait training alone. Adjunct tDCS therapy may improve outcomes, and reduce cost of both rehabilitation and post-stroke care.

Rivaroxaban Versus Warfarin for Stroke Patients With Antiphospholipid Syndrome, With or Without SLE (RISAPS): a Randomised, Controlled, Open label, Phase II/III, Non-inferiority Trial. 140 patients will be randomised with a ratio of 1:1 to receive either: Rivaroxaban 15mg twice daily orally for 24 months or Warfarin (standard of care in the RISAPS trial) to maintain a target INR of 3.5 (range 3.0-4.0) for 24 months. The primary outcome of the trial is the rate of change in brain white matter hyperintensity (WMH) volume between baseline and 24 months follow up, assessed on brain magnetic resonance imaging (MRI), a surrogate marker of ischaemic damage.

Study Design: Lixiana Acute Stroke Evaluation Registry (LASER) is a randomized controlled trial with an associated registry. Patients with previously known or newly diagnosed atrial fibrillation (AF) and acute ischemic stroke within five days will be randomized 2:1 to early (≤ 5 days) or delayed (6-14 days) edoxaban initiation. Ischemic stroke will be defined as evidence of acute focal cerebral infarction confirmed on CT/MRI and/or focal hypoperfusion/vessel occlusion on multimodal CT, or by sudden focal and objective neurological deficits (i.e NIHSS ≥ 1) of presumed ischemic origin persisting > 24 hours. Study Aim and Objectives: The primary aim of LASER is to demonstrate the safety of edoxaban initiation within five days of cardioembolic stroke. Secondary aim is to determine predictors of hemorrhagic transformation (HT) after cardioembolic stroke. Investigators will systematically assess prospectively collected Computed Tomography (CT) scan images for evidence of HT and re-infarction.

Intracranial atherosclerotic disease is the most common cause of ischemic stroke that is directly attributed to the progression or rupture of intracranial high-risk plaque in Asia. Many studies mainly from Euro-American population with a focus on extracranial carotid plaque have fully demonstrated the advantages of intensive statin therapy on stabilizing or reversing plaque burden, reversing plaque composition presenting that lipid-rich necrotic core (LRNC) is gradually replaced by fibrous tissue, and even reversing pattern of arterial remodeling to reduce the occurrence of cerebrovascular events. Yet, direct evidence of the effect of intensive statin therapy on intracranial atherosclerotic plaques is lacking and the effect of statin intensity and duration on intracranial plaque burden and composition is still unclear. High resolution magnetic resonance imaging (HRMRI) is a new and non-invasive technique that enable to assess the morphologic characteristics of vascular wall and plaque composition of intracranial artery. Based on above discussion, the investigators conduct this study to further determine the effect of intensive statin in ischemic stroke with intracranial atherosclerotic plaques.

Researchers are looking for a better way to prevent an ischemic stroke which occurs when a blood clot travelled to the brain in people who within the last 72 hours had: an acute stroke due to a blood clot that formed outside the heart (acute non-cardioembolic ischemic stroke), or TIA/mini-stroke with a high risk of turning into a stroke (high-risk transient ischemic attack), and who are planned to receive standard of care therapy. Acute ischemic strokes or TIA/mini-stroke result from a blocked or reduced blood flow to a part of the brain. They are caused by blood clots that travel to the brain and block the vessels that supply it. If these blood clots form elsewhere than in the heart, the stroke is called non-cardioembolic. People who already had a non-cardioembolic stroke are more likely to have another stroke. This is why they are treated preventively with an antiplatelet therapy, the current standard of care. Antiplatelet medicines prevent platelets, components of blood clotting, from clumping together. Anticoagulants are another type of medicine that prevents blood clots from forming by interfering with a process known as coagulation (or blood clotting). The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care without increasing the risk of bleeding. The main purpose of this study is to learn whether asundexian works better than placebo at reducing ischemic strokes in participants who recently had a non-cardioembolic ischemic stroke or TIA/mini-stroke when given in addition to standard antiplatelet therapy. A placebo is a treatment that looks like a medicine but does not have any medicine in it. Another aim is to compare the occurrence of major bleeding events during the study between the asundexian and the placebo group. Major bleedings have a serious or even life-threatening impact on a person's health. Dependent on the treatment group, the participants will either take asundexian or placebo as tablets once a day for at least 3 months up to 31 months. Approximately every 3 months during the treatment period, either a phone call or a visit to the study site is scheduled on an alternating basis. In addition, one visit before and up to two visits after the treatment period are planned. During the study, the study team will: Check vital signs such as blood pressure and heart rate Examine the participants' heart health using an electrocardiogram (ECG) Take blood samples Ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. In addition, the participants will be asked to complete a questionnaire on quality of life at certain time points during the study.

Stroke is a medical condition which causes the cessation of blood flow to the brain cells and results in cell death and ultimately can lead to motor disorders, perception disorders, language disorders, sensory disturbances.It is well known that stroke is the leading cause of death and one of the greatest causes of long-term motor disability in adults.The incidence of stroke is increasing day by day in low-income countries as compared to high-income countries because of the effects of not using evidence-based practice in health-related conditions in low-income countries. In the last few years, several approaches have been used for the recovery of hand dexterity after stroke. Among them, the Mirror therapy, task-oriented therapy, robot-assisted rehabilitation and action observation has gained greatest attention.Action observation training is one of the new developing rehabilitation technique that targets motor learning by the activation of mirror neurons and is the most important approach that targets the motor and functional recovery in stroke patients. In action observation training, the movements are produced because of the external stimuli in which actually the visual attention recruit the cerebellar-thalamic-cortical circuit of the brain. Action observation is based on activities of the motor neuron system and they discharge mostly in association with complex tasks as compared to simple tasks.

The aim of our study is to investigate the effects of rTMS applications at different current frequencies (low frequency / intermittent (intermittent) theta burst (iTBS)) in stroke patients on lower extremity motor development, physical function and quality of life, and to compare the effectiveness of these modalities.

The aim of this randomized controlled is to assess the effect of kinesiotape technique upon wrist joint among the patients with chronic stroke. Patients are devided into groups, in group A kinesiotaping facilitation technique is applied on wrist extensor muscles while inhibition technique is applied on wrist flexor muscles and the result is the compared between the groups and within the group.
