Active clinical trials for "Stroke"

The trial is a multicenter, prospective, block randomized, open label, blinded-endpoint (PROBE) controlled design. Patients with acute ischemic stroke due to large vessel occlusion within 4.5-24 hours of symptom onset (including wake-up stroke and unwitnessed stroke) will be randomized 1:1 to 0.25mg/kg intravenous tenecteplase or standard medical treatment.

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 study will evaluate whether low-density lipoprotein (LDL-C) lowering with alirocumab results in greater change from baseline in intracranial atherosclerotic plaque at week 26 than control in adults with acute ischemic stroke from intracranial atherosclerosis taking lipid lowering therapy.

Stroke and its sequelae are a major indication for acupuncture. The specific aims of this study are to assess the feasibility of pragmatic clinical trial on acupuncture in primary care setting and evaluate the effectiveness and safety of acupuncture for stroke rehabilitation in Hong Kong.

Ischemic stroke is the leading cause of long-term disability in the United States. Endovascular intervention with mechanical thrombectomy has become the standard of care for acute large vessel occlusion (LVO) stroke since multiple clinical trials demonstrated improved long-term clinical outcomes with treatment. However, despite high rates of successful vessel recanalization and thus reperfusion of ischemic brain tissue in current practice, many patients continue to suffer debilitating strokes and poor long-term functional outcome. Pharmacologic neuroprotection could potentially present a means of addressing this mismatch in radiologic vs. clinical outcomes by protecting and salvaging damaged brain tissue. Intra-arterial delivery of a cocktail of neuroprotective therapy at the time of endovascular reperfusion would provide immediate, targeted therapy directly to the damaged brain territory. Hypothermia, minocycline and magnesium can target multiple facets of the complex ischemic injury cascade, and have each demonstrated neuroprotection in multiple preclinical models. This is a phase I trial that aims to demonstrate safety and feasibility of administering cold saline, minocycline, and magnesium sulfate intra-arterially immediately after thrombectomy in stroke interventions.

Adults with stroke-related disability spend more time sedentary than adults without stroke-related disability, which places them at risk for poor cardiovascular health outcomes. Few interventions are designed to reduce post-stroke sedentary time. The purpose of this research is to test whether the teleABLE (Activating Behavior for Lasting Engagement) Intervention is feasible and acceptable to adults within the first 12 months post-stroke. The hypothesis is that teleABLE can be feasibly delivered using videoconferencing within the first 12 months post-stroke. 10 participants will complete assessments and activity monitoring (activPAL micro3) at 0 (baseline) and 8 (post-intervention)-weeks. Participants will complete 12 sessions of the teleABLE intervention. Findings from this study will be used to guide the intervention protocol in the planned next phase of this research.

Mechanical thrombectomy (MT) has shown its effectiveness for the treatment of acute ischemic stroke (AIS) related to large vessel occlusion and rapidly became a cornerstone in the management of these patients. No strong evidence is available on the benefit of MT in AIS related to more distal occlusions. Some previous observational studies suggested a possible benefit but most of them were single-centre and retrospective studies providing a very low level of evidence. To date, no randomized controlled trial has been conducted in this indication, which represents 10% to 20% of all AIS involving intracranial vessel occlusions. This research is a multicenter open randomized controlled trial with two parallel groups : best medical treatment alone VS mechanical trombectomy + best medical treatment.

Stroke patients do not respond well to the traditional repetitive transcranial magnetic stimulation (rTMS) strategy based on the competitive model. The studies found that the contralesional motion cortex has a compensatory effect on the realization of the motor function of the affected side-the compensatory model, and the degree of compensation will change as the function changes. The optimal neural regulation strategies under different models are opposite, so it is important to accurately evaluate which of the two models plays the leading role. And functional near-infrared spectroscopy (fNIRS) may accurately and quickly assess cortical function in order to determine the degree of participation of the contralesional motion cortex. We propose that the dynamic individualized strategy which adjust the rTMS parameters promptly based on the results of fNIRS will be better than the traditional stimulation strategy. This project will apply a blinded-assessment randomized controlled trial. The test group selects either the high-frequency rTMS to the contralesional dorsal premotor cortex (PMd) or the low-frequency rTMS to the contralesional primary motor cortex (M1) based on the lateralization index of the PMd measured by fNIRS. And the control group will always be given low-frequency rTMS to contralesional M1. The difference in the improvement of upper limb function between the two groups of patients was compared.

Few treatments are available for post-stroke rehabilitation. The current study aims to develop a novel, short-term, high-dose repetitive transcranial magnetic stimulation (rTMS) based intervention to improve post-stroke cognitive problems. This study will test the safety as well as changes in cognitive function and brain activation with the administration of an accelerated rTMS protocol in chronic stroke.

The present study aims to determine the effect of the ten-session dual tDCS combine with physical therapy on gait performance, balance, and lower limbs muscle strength in patients with subacute stroke.
