Filter by:Stroke is a major cause of morbidity in western society, and an infrequent complication of cardiac surgery. The majority of thromboembolic strokes arise from the left atrium, in particular the left atrial appendage. This study aims to assess the short-term effects of left atrial appendage ligation in terms of postoperative clinical and biochemical parameters; and the long-term effects of left atrial appendage ligation in terms of stroke incidence.
This study will examine how the brain rewires itself to make up for the lack of movement many people with stroke experience. It will try to determine if the rewiring differs depending on the location of the stroke and the amount of time since the stroke occurred. For some stoke patients, weakness may persist, while others recover completely after time. It is not known which parts of the brain are involved in the recovery of different types of stroke and if the type of stroke affects recovery. People 18 years of age and older who have had subacute thromboembolic or hemorrhagic stroke more than 3 months before enrolling may participate in this study. Participants come to the NIH Clinical Center three times every 2 years for up to 10 years. At the first visit, patients have a neurological examination and perform tests of motor abilities such as lifting small objects, turning cards, using a spoon, stacking checkers and lifting cans during a short period of time as rapidly as possible. At the second visit, subjects have structural magnetic resonance imaging (MRI) scans of the brain. MRI uses a strong magnetic field and radio waves to obtain images of body organs and tissues. The MRI scanner is a metal cylinder surrounded by a strong magnetic field. During the scan, the subject lies on a table that can slide in and out of the cylinder, wearing earplugs to muffle loud knocking noises associated with the scanning process. Total scan time is about 30 minutes At the third visit, subjects perform some simple movement tasks during functional MRI (fMRI) scans. The procedure is the same as with structural MRI, except that subjects are asked to perform simple movement tasks in the scanner. Before the fMRI scans, electrodes are attached to the subject's arms and legs to monitor muscle activity (surface electromyography). Total scan time is about 1.5 hours. Movement tasks might include pinching a force-measuring instrument with the fingers, pressing different keys on a keyboard as fast as possible, inserting pegs into small holes on a board, lifting weights, flipping cards or similar activities.
This is a study to confirm the superior efficacy of GSK1358820 over placebo in patients with equinus deformity associated with post-stroke lower limb spasticity using the Modified Ashworth Scale (MAS) ankle score.
This is a study to confirm the superior efficacy of a single treatment of GSK1358820 over placebo in patients with post-stroke upper limb spasticity of both the wrist and finger flexors using the Modified Ashworth Scale (MAS) wrist score.
Physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)

The purpose of this study is to assess the safety and feasibility of the NeuroFlo™ catheter in treating patients with ischemic stroke whose last time symptom-free was between 8-24 hours prior to treatment. The NeuroFlo device is intended to increase blood flow to the brain and potentially reduce the damage caused by stroke.
The primary aim of this study is to investigate the effectiveness of the use of a robotic hand therapy device in the home environment. We hypothesize that the therapy group will improve hand function more than a customary and usual care group.
Regular exercise has been demonstrated to improve muscle strength, balance, coordination as well as improve cardiovascular fitness levels and overall quality of life in stroke survivors. This study is designed to test the feasibility and effectiveness of a 12-week intervention to education and encourage stroke survivors to exercise following discharge from rehabilitation settings using a walking program and targeted functional activity homework.
