NCT05013762
Every year, almost 800,000 people experience a stroke in the United States, which lead to upper-limb impairments, making recovery of motor function a priority in stroke rehabilitation. 1) The primary objective of this study is to determine whether fast arm movement training on a tracking task ("Speed-training"), in chronic stroke survivors with mild to moderate paresis, will generalize to improve arm function better than dose-equivalent accuracy training on the same task. 2) study the effect of intensive arm training on the recovery of anticipatory feedforward control. 3) Determine the involvement of cerebellar-cortical circuits in the recovery of arm movements due to speed training.
NCT05361187
Evaluation of the safety and performance of the BOBBY™ Balloon Guide Catheter (BGC) in patients with an acute ischemic stroke treatment, a sudden reduction or termination of the blood circulation of the brain, caused by a clot. Immediate treatment is needed to restore the blood circulation in the brain, performing a mechanical removal of the clot (thrombectomy). To prevent clot particles migrating in other parts of the brain circulation during the thrombectomy, balloon guiding catheters are inserted. The aim of the study is to evaluate the safety and performance of the balloon guide catheter BOBBY™ by collecting information from patients, treated with a mechanical thrombectomy and the balloon guide catheter (BOBBY™) after acute ischemic stroke
NCT02038998
Stroke is one of the leading causes of death and disability worldwide. More than 85% of strokes are due to blood vessel occlusion resulting in partial destruction of the brain parenchyma. Current protocols try to re-establish blood circulation as soon as possible through chemical and/or mechanical interventions but new strategies are needed. Periodic acceleration (pGz) is a non-invasive method consisting in the application of a rocking movement to the patient that ultimately will induce the release of beneficial chemicals from the vascular endothelium (the cells lining the inside of the blood vessels). Application of pGz in an animal model of stroke resulted in a dramatic reduction of associated brain damage. This trial will investigate whether stroke patients exposed to pGz experiment significantly higher recovery than patients that remained static during their treatment.
NCT03417349
Sesame is a European, multi-center, single arm, prospective, observational registry. Sesame aims to demonstrate that use of SOFIA™/SOFIA™ PLUS catheter for direct aspiration as a first line treatment technique is fast, safe and effective in patients suffering an Acute Ischemic Stroke when assessed at 24 hours, discharge and 90 days after treatment. 250 patients will be enrolled. All patients will be followed for 90 days or until death.
NCT04297345
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.
NCT04870684
In ischemic stroke, the recanalization rate after intravenous thrombolysis has been estimated to be less than 50% in patients with proximal intracranial artery occlusion; this rate is greater than 80% after endovascular thrombectomy. Thromboelastometry is a method of analysis of coagulation and fibrinolysis in whole blood. The main objective of this study is to evaluate whether the parameters obtained by thromboelastometry are predictive of revascularization at arteriography during mechanical thrombectomy, after treatment with rt-PA thrombolysis.
NCT04377022
Stroke is one of the major cause of morbidity and mortality and the leading cause of disability in adults all around the world. Stroke survivors can suffer several neurological impairments and deficits which have an important impact on patient's quality of life and which increase the costs for health and social services. After stroke, impairments in ADLs and functional status, deterioration in health related quality of life can be seen. The purpose of this study is to Determine the effect of Aerobic exercise training on Balance, Walking capacity and quality of life in sub-acute stroke.
NCT04378946
Deficits in upper limb (UL) functional recovery persist in a large proportion of stroke survivors. Understanding how to obtain the best possible UL recovery is a major scientific, clinical and patient priority. We propose that UL motor recovery may be improved by training that focuses on remediating an individual's specific motor impairment. Our approach is based on evidence that deficits in the control of muscle activation thresholds (spatial thresholds) of the elbow in stroke underlie impairments such as disordered movement and spasticity. Our novel training program focuses on improving the individual's active elbow control range using error augmentation (EA) feedback. Since training intensity and lesion load are key factors in motor recovery that lack guidelines, we will also investigate effects of exercise dose and corticospinal tract (CST) injury on UL recovery. In this multicenter, double-blind, parallel-group, randomized controlled trial (RCT), patients with stroke will participate in an individualized intensive technology-assisted reaching training program, based on error augmentation (EA), in order to improve voluntary elbow function. They will practice robot-assisted reaching in a virtual reality (VR) game setting. We will identify if intensive training with feedback aimed at expanding the range of spatial threshold (ST) control at the elbow (experimental group) is better than intensive training with general feedback about task success (control group). We will also determine the patient-specific optimal therapy dose by comparing kinematic and clinical outcomes after 3, 6 and 9 weeks of intensive training, and again at 4 weeks after training to determine carry-over effects. We will quantify the severity of the participant's motor deficit, as the amount of cortico spinal tract (CST) injury due to the stroke (%CST injury) and relate training gains to their %CST injury. Results of this pragmatic trial will provide essential information for optimizing individualized post-stroke training programs and help determine optimal patient-specific training dosing to improve motor recovery in people with different levels of stroke severity. This type of research involving personalized, impairment-based feedback and dose-effective training has the potential to significantly improve rehabilitation for a greater number of post-stroke individuals and improve the health and quality of life of Canadians.
NCT03701412
Cerebral microbleed (CMB) refers to small, round dark-signal lesions detected by T2\*-weighted or gradient-echo (GRE) magnetic resonance imaging (MRI) ..CMBs were introduced to stroke physicians in the late 1990s and early 2000s after development of MRI techniques sensitive to paramagnetic effects The clinical significance of CMBs has been actively investigated, especially in the stroke field and more recently in studies on cognitive impairment, vascular dementia and later developement of cerebral hge ..Histological investigation has shown that CMBs are tiny foci containing hemosiderin-laden macrophages and abnormal microvessels . Clinical cases with frank symptoms caused by CMBs are uncommon, Because CMBs are manifestations of focal extravascular leakage of blood components, however, investigators have suggested that accumulation of CMBs reflects a bleeding-prone status in individuals with an elevated risk of cerebral hemorrhage. Clinical studies have found strong associations between CMBs and chronic hypertension and low cholesterol levels and between the proximity and volume of CMBs and those of subsequent intracerebral hemorrhage (ICH) . studies have found that CMBs are linked to subsequent hemorrhagic stroke in stroke survivors,and suggested that CMBs are related to antithrombotic-related hemorrhage.

In patients admitted to hospital with acute cerebrovascular stroke, we want to study the relationship between hair cortisol levels and biomarkers of inflammation and the clinical and radiological severity of the stroke and the degree of neurological disability being tested in three months and one year after.
NCT02885545
Patients with severe chronic kidney disease (CKD) who develop atrial fibrillation are at high risk for stroke. The use of blood thinking medication in dialysis patients is controversial and warfarin carries a serious risk for major bleeding. The Watchman device may be an ideal therapy for this population as after implantation it allows for the discontinuation of blood thinners, thereby reducing the risk of bleeding.
NCT01133106
The overall goal of this study is to conduct a three-armed randomized controlled trial (RCT) in stroke survivors with depression to determine if a brief psychosocial-behavioral therapy intervention delivered in-person (arm A) or by telephone (arm B) is better than usual care (arm C), in terms of percent reduction in depressive symptoms and % of participants achieving remission of symptoms.
NCT02690493
The purpose of this study is to determine whether acupuncture and taping are effective in the treatment of spastic upper limb after stroke.
NCT00671346
Two large homocysteine-lowering B-vitamin intervention trials have been performed in Norway during the period 1998 to 2005, NORVIT and WENBIT. The main objective in these trials was to study the clinical effects of homocysteine-lowering therapy with folic acid and vitamin B12 in patients with established coronary artery disease. Follow-up was terminated for NORVIT on Marc 31st 2004 and for WENBIT October 5th 2005, and none of the two trials proved any protective effect of the B-vitamin intervention on cardiovascular outcomes. There is so far no data on possible long-term effects following years of such B-vitamin treatment. Thus, the main objective of the combinded NORVIT-WENBIT study will will be to evaluate the long-term effect of the B-vitamin intervention on incident life-style diseases including cardiovascular disease, diabetes, osteoporotic fractures and cancer. A secondary object will be the identification of risk phenotypes or genotypes, and if such risk associations are midified by the B-vitamin intervention
