Active clinical trials for "Stroke"

Improving upper extremity movement and function in patients with stroke has been one of the primary goals for patients and rehabilitation professionals. Thermal stimulation (TS) had been first found by a domestic research group to be effective to facilitate sensory and motor recovery in patients with stroke within a month. However, the immediate and long-term effects of TS and the mechanism of brain plasticity in patients with stroke for more than three months (golden recovery stage) remain unknown. Thus, we will design a single-blind randomized controlled trial to investigate the immediate and long-term effects of TS in patients with stroke at subacute and chronic stages.

To determine the revascularization rate of the CE-marked Trevo device in large vessel occlusions in ischemic stroke patients. Revascularization, defined as at least TICI 2a in the vascular territory treated at end of the neuro interventional procedure.

The purpose of this study was to investigate the effects of gait training on ground level with partial body weight support (BWS)in individuals with stroke during overground walking with no BWS.

The purpose of this study is to see whether treating subjects for wrist rehabilitation following stroke with Botox® and robotic therapy is more effective than treatment with robotic therapy alone and no Botox®.

Approximately 780,000 people suffer a stroke annually in the United States; 200,000 are recurrent strokes. The 17,000 veterans who suffer a stroke yearly are at great risk for a second stroke and therefore should be targeted for stroke risk factor management and prevention interventions. Balance and fear of falling negatively impact activity and function. Decreased activity and blood pressure (BP) are important modifiable stroke risk factors. These can be addressed through a yoga exercise intervention. Yoga, like tai-chi, is old world alternative medicine that has the potential to greatly impact the lives of older adults.

Stroke is the leading cause of adult disability and the third leading cause of death in Canada. Most stroke survivors live with residual impairments that diminish independence and quality of life. This may include vascular cognitive impairment (loss of ability to plan, think and reason) which can lead to dementia and loss of mental and functional independence. The current treatment to reduce stroke induced brain tissue injury is limited to thrombolytics (clot busters), a therapy useful only if given in the first hours following stroke. One major new approach aims to reduce cell death after stroke by targeting the ongoing tissue loss initiated by the stroke. The tissue can be maintained by interfering with later neurochemical processes that are activated by stroke, potentially through activating natural substances in the brain that help survival and growth of nerve cells ("neurotrophic" factors). The recent recognition of lithium as a neurotrophic agent has generated the first studies of lithium treatment for managing brain diseases. Clinically, lithium has now been shown to increase brain gray matter volume in bipolar patients. This effect is potentially important in stroke because gray matter loss has been implicated in the development of cognitive impairment after stroke, a result of the series of brain processes that are activated by lack of oxygen due to stroke. Our primary objective is to examine the effects of lithium on total brain gray matter volume in the post-stroke population, as measured by volumetric magnetic resonance imaging (MRI) with the hope that lithium may increase gray matter volume in post-stroke patients and lead to greater cognitive and functional rehabilitation. This study will provide valuable information on the tolerability of lithium, and its effects on clinical outcomes relevant to stroke, providing the information needed for designing a large-scale clinical trial.

The goal of this study is to determine whether task-oriented, robot-aided therapy is more effective than conventional physical and occupational therapy at promoting functional recovery of the affected arm in chronic hemiparetic stroke patients.

Each year 730,000 Americans experience a stroke. Forty percent are left with significant paralysis of one arm. Certain types of physical therapy, for example constraint induced movement therapy (CIMT), have been shown to be effective in improving arm function. However, for most subjects, improvement is modest. In this trial, we test two approaches that may increase the amount of improvement achieved: 1) distributing treatment over a greater amount of time; and 2) adding a drug, d-cycloserine, which theoretically enhances the molecular mechanisms of learning.

The purpose of this study is to evaluate the safety and tolerability of SA4503 in patients recovering from a recent stroke. Secondary, to evaluate the efficacy of SA4503 compared to placebo.

This randomized, single-blind study compares the effectiveness of bilateral training to unilateral training for individuals with moderate hemiparesis. We hypothesize that bilateral training will be superior to unilateral in the proximal extremity but not the distal one.
