Filter by:This study is designed to determine whether there is a relationship between the way insulin and blood vessels work. The difference in the interaction between Caucasian and African American adolescents will also be examined. This may play a role in the differing rates of heart disease and diabetes between the two groups.
Between twenty and fifty percent of people who have acute stroke have hyperglycemia (high blood sugar) with it. Research has shown an association between hyperglycemia and poor recovery from stroke. However, it is not known if treating the hyperglycemia—bringing the blood sugar back to normal range—will improve the patient's recovery from stroke. This purpose of this study is to see if giving Insulin to normalize the blood sugar will decrease the size of the stroke in the brain and improve the patient's neurologic recovery. We hypothesize that early insulin administration to normalize blood glucose levels may be beneficial in cerebral ischemia and stroke.
This study will compare robotic training with usual care and intensive comparison therapy to attempt to improve upper extremity function.
The purpose of this study was to determine the effect of two amounts of treatment therapy on post stroke motor recovery in the arms. The therapy is bilateral movement training combined with electrical stimulation on the impaired limb.
New stroke therapies are needed. This study seeks to provide the preliminary data needed to plan a future study that will evaluate the efficacy of using continuous positive airway pressure (CPAP) to treat stroke patients who have sleep apnea. Our goal is to use this therapy to reduce stroke symptom severity.
The purpose of this study is to compare modified CI therapy for strokes survivors with very limited function to an alternative package of conventional physical rehabilitation techniques
This study will examine whether transcranial magnetic stimulation (TMS) of the brain used in combination with carbidopa-levodopa is more effective in temporarily improving the speed of hand movement in stoke patients than TMS alone. In TMS, a wire coil is held on the patient's scalp. A brief electrical current is passed through the coil, creating a magnetic pulse that stimulates the brain. The effect of TMS on the muscles is detected with small metal disk electrodes taped to the skin of the arms or legs. Carbidopa-levodopa is a medication usually used to treat Parkinson's disease, but it may improve the effect of theta burst stimulation. Two kinds of TMS are used in this study. In single-pulse TMS one or two pulses are delivered at a time in order to measure brain activity at that moment. In repetitive TMS (rTMS), a series of pulses are given in short bursts, temporarily altering brain activity. The type of rTMS used in this study is called theta burst stimulation. Healthy normal volunteers and people who had a stroke 6 months or more before entering the study may be eligible to participate. All candidates must be between 18 and 90 years of age. Stroke patients must have had significant hand weakness and made a moderate or good recovery and must be able to move either the thumb or the wrist on the affected hand reasonably well. Normal volunteers must be right-handed. Participants complete the testing for this study in four main sessions scheduled at least a week apart and five short follow-up sessions. At each main session, participants take either a carbidopa-levodopa tablet or a placebo (a look-alike inactive substance). Stroke patients have their arm and hand function assessed using two tests. One requires them to insert pegs into holes; the other includes writing, lifting various objects, and performing activities like turning pages, feeding or stacking checkers. All subjects complete a questionnaire regarding their mood and alertness and then perform tests of thumb or wrist movement. For this test, a small electrical stimulus is applied to the side of the hand and the subject must respond to the stimulus as quickly as possible by making a thumb or wrist movement. This is repeated several times over about 3 minutes. A second test follows in which the subject moves the thumb or wrist in response to a beep from a speaker. This test is repeated several times over about 8 minutes. Some measurements are taken using single-pulse TMS during the beginning, middle and end of this test. In two of the four sessions, theta burst stimulation is applied after the single-pulse TMS and in the other two sessions, sham theta burst stimulation is applied. Five follow-up sessions are scheduled one day after each main session and one week following the final one. In these sessions, subjects perform an abbreviated form of the thumb movement tests.
The purpose of this study is to determine whether rosuvastatin is effective in the management of acute phase of intracerebral hemorrhage and if it impact outcome by NIHSS.
Pilot study of continuing aspirin versus switching to clopidogrel after stroke or transient ischemic attack.
The purpose of this study is to assess the safety of Beta-hCG + Erythropoietin in patients with acute ischemic stroke.
