Enrollment of a population-based, prospective cohort of 3298 stroke-free adults was completed in 2001 and annual follow-up has continued since then. This collaborative study is the first prospective cohort study among whites, blacks and Caribbean Hispanics living in the same community. This grant supports continued follow-up and outcome detection and expansion of data collection in this cohort. The aims are to evaluate the relationship between vascular outcomes (stroke, myocardial infarction (MI), and vascular death) and insulin resistance, carotid intima-media thickness, carotid distensibility, and quantitative magnetic resonance imaging (MRI) measures of vascular subclinical brain disease and to determine if MRI subclinical disease accounts for race/ethnic differences in cognitive impairment. To accomplish these aims further data collection using the population-based, prospective cohort study is proposed. Stored baseline serum will be used to measure fasting insulin levels to evaluate insulin resistance. High-resolution carotid imaging data will be collected at subsequent visits to expand the measurements of subclinical carotid disease to 1300 subjects. MRIs and a neuropsychological battery emphasizing frontal executive domains will be done on 1300 subjects and quantitative analyses performed to measure white matter hyperintensities, silent infarcts, and silent cerebral microbleeds. Starting in 2005, subjects enrolled in the MRI substudy began to have echocardiograms and 24hour ambulatory blood pressure monitoring. Subjects will be followed by annual telephone interviews to ascertain stroke, MI, death, and changes in cognitive state. In-person assessment will be done for all subjects who screen positive. Community stroke surveillance will be maintained to insure stroke detection among the cohort. Specific diagnostic committees classify stroke, MI and vascular death.
Role of anti-platelet in treatment of acute ischemic stroke to determine the safety of immediate anti-platelet therapy .that is started as soon as possible within the first 24 hours of the onset of symptoms.
Ischemic strokes are the first cause of handicap in adult people, the second cause of dementia and the third cause of death in France. Brain Magnetic Resonance (MR) initial assessment is mandatory to get the right diagnosis, to exclude hemorrhagic lesions and to determine the best treatment. The conventional diffusion weighted imaging sequence is used to establish the diagnosis and to estimate the volume of ischemic lesions. The perfusion weighted imaging sequences are also used to assess the diffusion-perfusion mismatch which is supposed to be the ischemic penumbra corresponding to territories that could be saved with appropriate treatments. IntraVoxel Incoherent Motion (IVIM) is a multi-b diffusion sequence which allows to extract four quantitative variables (D, D*, f, ADC) related to the true molecular diffusion and correlated to the microvascular perfusion. It's a quick sequence with no need of contrast injection and allowing a perfect coregistration with the true diffusion. It has been validated in many pathologies but not in acute strokes. The feasibility of this sequence in acute ischemic strokes has already been assessed with interesting results. The study aims to assess the correlation between the quantitative values of IVIM at initial MR exam and the modified Rankin Scale (mRS) score 3 months after an acute ischemic stroke.
Patients are assigned to KSW's Stroke Unit as part of the emergency treatment. There the patients are included in the study and treated according to the concept on the Stroke Unit within the complex treatment. The patients are included after clarification and with the consent of the patients. On the morning after the day of intake, the first determination of the ghrelin takes place in the routine blood sampling. Similarly, 48 hours later and 3 months after the stroke, a blood sampling is performed to determine ghrelin. The De Morton Mobility Index (DEMMI), the 9-hole-peg assay and the modified Rankin Scale (mRS) are determined on the day of admission, on the 3rd day, and three months after stroke. This is done within the framework of the routine clarification and treatment on the Stroke Unit.
To compare the effect of constraint induced movement therapy (CIMT) vs. treadmill training only on walking function in individuals post-stroke, a 6 week, single-blind, randomized training study will be conducted with three assessments of gait to determine the training effect. Subjects will be randomized to either the CIMT or treadmill training only groups at the initial test. Following the initial test, individuals from the 2 groups will undergo intensive locomotor training. Training will be performed 3 times per week for 6 weeks with the training time for each visit set to 45 minutes as tolerated. Data collection will proceed until 36 subjects from 2 groups have been trained.
Hypothesis/Specific Aims: The purpose of this research study is to determine if using an exoskeleton during stair climbing training will result in an improved ability to walk and climb stairs in individuals affected by recent stroke as compared to stair climbing training without an exoskeleton.
Stroke is the second leading cause of death worldwide and the third most common cause of disability. The effects of stroke are variable and may include impairments in motor and sensory systems, emotion and neuropsychological deficits such as a disorder of spatial awareness known as unilateral spatial neglect (USN). Approaches to ameliorate USN could be categorized in interventions as involving either bottom-up or top-down processing. The specific mechanisms underlying these effects on a number of manifestations of the USN syndrome may include the restoration of defective representations of the side of space contralateral to the lesion (contralesional), and of the ability to orient spatial attention contralesionally, through complex patterns of activation of both the damaged right hemisphere, and the contralateral left hemisphere, with differences related to the specific stimulation delivered to the patient. In recent years, increasing cutaneous stimuli through neuromuscular kinesiotaping has been proposed to enhance somatosensory inputs (24) and such as method could have positive effects on USN. The aim of the present study was to assess the effect of KTM applied on the sternocleidomastoid muscle controlateral side of the lesions in improving USN deficits in individuals with stroke patient in sub-acute phase. The hypothesis is that the KTM application could improved cognitive tests for assessing USN, motor deficits and kinesthetic neck sensibility.
This research will evaluate the potential for a novel hand orthosis (HandSOME) to help stroke victims regain functional use of their hand and regain independent living. Participants will use the HandSOME at home regularly for 8 weeks. Clinical evaluations will measure changes from the intervention after the 8 weeks and also at a 3 month followup.
Objectives: This study aims to estimate overall treatment benefit (improvement in disability) among acute ischemic stroke patients that are randomized to General Anesthesia (GA) compared with Sedation (CS) during endovascular therapy. Assess safety (as measured by incidence of symptomatic intracranial hemorrhage); rates of Endovascular therapy (EVT) procedural complications, reperfusion; and quality of life. Hypothesis: GA during EVT for acute ischemic stroke improves functional outcomes at 90 days compared to sedation.
