Active clinical trials for "Stroke"

Oropharyngeal dysphagia (OD) is a major complaint among many patients with stroke and causes severe complications. There is no specific treatment for these patients. Impaired swallow response is caused by a delay in the timing of oropharyngeal reconfiguration with delayed airway protection. Swallow response is initiated by sensory afferent fibers in the oropharynx and cerebral cortex reaching the central swallowing pattern generator (CPG) in the medulla oblongata and brainstem motor nuclei. Hypothesis: Stimulation of pharyngeal sensory afferent fibers through TRPV1 receptors and electrical stimuli might enhance the stimulation of the CPG and speed the swallow response. Long-term treatment of OD will improve clinical outcome of stroke patients. Aim: To assess the effect of TRPV1 agonists (capsaicin) and that of sensorial pharyngeal electrical stimulation (intrapharyngeal and transcutaneous) on VFS signs and swallow response at 3, 6 and 12 months after treatment in stroke patients with established OD. To compare the clinical effect of classical rehabilitation strategies with that of these new afferent sensorial neurostimulation strategies in terms of nutritional status parameters, incidence of aspiration pneumonia and/or low respiratory tract infection, quality of life, and mortality. Methods: Clinical screening of OD with the volume-viscosity swallow test and assessment by VFS and quantitative measurements of swallow response. Randomized controlled trial assessing the effect of standard rehabilitation with that of afferent sensorial neurostimulation strategies.

Patients with cancer who develop stroke are at high risk for future strokes or other clotting events. These patients are routinely treated with medicines that thin their blood, including enoxaparin or aspirin. However, it is unclear which medicine is best and whether these medicines can be adequately studied in a clinical trial. The purpose of this Phase I/II study is to determine if a clinical trial of different blood thinners in patients with cancer and stroke is possible. In addition, the study aims to compare the effects, good and/or bad, of enoxaparin with those of aspirin on patients with cancer and recent stroke.

This is a 20-week study consisting of a 12-week multicenter, randomized,double-blind adaptive study to compare efficacy and safety of Qizhitongluo Capsule,Naoxintong Capsule and placebo in the recovery phase of ischemic stroke with qi deficiency and blood stasis syndrome, and a 8-week post-treatment safety follow-up.After 312 patients complete 12 weeks of treatment there will be an interim analysis.

The investigators aimed to evaluate effects of combined NMES, FEES and traditional swallowing rehabilitation in stroke patients with moderate-to-severe dysphagia.

Both aerobic training (AT) and resistance/strength training (RT) have the potential to improve recovery after stroke. Research conducted in chronic disease and healthy populations suggest that AT and RT "combination therapy" may produce synergistic and superior effects along cognition and mobility domains, when compared to AT alone. However, the effects of a combined training approach (AT+RT) compared to AT alone has not been investigated in people post-stroke.

The purpose of this trial is to assess the safety and effectiveness of the Penumbra System as an adjunctive treatment to intravenous (IV) recombinant human tissue plasminogen activator (rtPA)in patients with acute ischemic stroke from large vessel occlusion in the brain. IV rtPA is the only drug approved for the treatment of acute ischemic stroke but it does not work very well in cases where the stroke is caused by a large vessel occlusion. The hypothesis being tested is to determine if the addition of a treatment by a mechanical thrombectomy device like the Penumbra System can improve the clinical outcome of the patient over just using IV rtPA alone.

In literature review, thermal stimulation (TS) intervention is effective in facilitating upper extremity functional recovery in stroke patients. In addition, several functional MRI studies have indicated that thermal stimuli promoted activation in the premotor and motor cortices of healthy participants. These imply the possibility of TS in cortical reorganization. However, there were no studies exploring the relationship of the TS intervention and cortical reorganization. By the functional recovery of stroke patients, findings of brain image and brain mapping, it could enhance the understanding the TS influences on brain reorganization. Regarding with clinical application of the TS intervention for improving functional performance of upper extremity in participants with stroke, the best parameters of TS intervention in clinical practice have not been decided. Therefore, this five-year study recruited three groups of stroke patients (acute, sub-acute, chronic) undergoing TS intervention with different parameters. Functional scales, kinematic data, brain image were taken in several timelines as outcome measures.

This investigation will address the safety and feasibility of distal, intra-arterial sampling through endovascular access, in acute stroke patients. Levels of Magnesium will be measured in the region of infarct in patients who had been treated with intravenous Magnesium therapy following an acute stroke. This study attempts to address whether the traditional intravenous means of neuroprotectant administration achieves adequate concentration of the therapeutic agent in the area of diseased tissue.

The purpose of the study is to assess the efficacy of a new serotonin-norepinephrine reuptake inhibitor (SNRI) nin functional recovery after ischemic stroke.

That the Jan Medical Nautilus NeuroWaveTM system provides significantly higher sensitivity to hyper acute ischemic stroke than does CT.
