Filter by:The investigators are performing a study to determine whether changes in blood flow occur in the neck and back of the brain following a series of head positions and a manipulation of the upper neck. Each participant will be asked to undergo a series of MRI's to evaluate whether there are any changes in blood flow resulting from any of the head positions or manipulation. The study will be conducted over a period of 1 day and each participant can anticipate the testing to take approximately 120 minutes.
This trial is a multicenter, open-label study to evaluate the safety and efficacy of GSK1358820 for treatment in post-stroke subjects with focal wrist, finger and in some cases, thumb spasticity. Qualified patients who complete GSK double-blind study 112958 will be enrolled. Subjects will receive a single treatment session of intramuscular GSK1358820 "200U or 240U (if thumb spasticity is present)". The subjects will be observed until 12 weeks post injection. Outcome measures include changes from baseline at every post injection visit as measured on the Modified Ashworth Scale (MAS), Disability Assessment Scale (DAS) and Global Assessment Scale. Safety parameters will be measured including adverse events, vital signs (pulse and blood pressure) and clinical laboratory tests (haematology, serum chemistry and urinanalysis).
This study will compare the diagnostic accuracy of Card 28 stroke protocol to Card 28 and Cincinnati Stroke Scale, when used by emergency medical dispatchers to interrogate a 911 call suggestive of stroke. The authors hypothesize that a combination of Card 28 plus the Cincinnati Stroke Scale (CSS) will improve the diagnostic accuracy of emergency medical dispatchers for stroke.
To investigate the efficacy of using transcranial alternating current stimulation (tACS) to enhance the regaining of neurological function among post-stroke patients.
The investigators hypothesize that application of electrical stimulation would augment the effects of exercises in patients with stroke. Combined electrical stimulation with exercises for 6 weeks would lead to earlier and greater improvement in motor functions when compared with placebo-stimulation with exercises.
1. Objectives and Hypothesis 1. Objectives: This study evaluates whether strict BP management is useful for the prevention of recurrent stroke. Hypertensive patients with history of stroke are treated with stepwise multi-drug therapy to achieve stricter BP target <120/80 mmHg in the strict BP control group and less stricter BP target <140/90 mmHg or <130/80 mmHg for patients with current DM/CKD/MI in the standard BP control group. The participants under the BP treatment achieving their respective BP target will be followed for recurrence of stroke. The study continues until the number of patients with the first recurrent stroke reaches a total of 330 between the two groups. The occurrence rates of recurrent stroke will be compared between the two groups. 2. Hypotheses The incidence of recurrent stroke will be lower in a strict BP control group having lower BP target: <120/80 mmHg* than in a standard BP control group having BP target <140/90 mmHg or <130/80 mmHg for current DM/CKD/MI in patients with hypertension. 2. Study design This will be a multicenter, randomized, open-label study. The study consists of a screening period, a titration period and a follow-up period. The screening period is a period between the date of consent and the enrollment date. Hypertensive patients with history of stroke are randomly assigned to either the strict BP control group having the target of <120/80 mmHg or the standard BP control group having the target of <140/90 mmHg without current DM, CKD or MI and <130/80 mmHg with current DM, CKD or MI. The titration period is the period finding a treatment which achieves target BP, and 24 weeks at maximum. Patients will be treated with stepwise multi-drug therapy using an angiotensin-receptor antagonist, diuretic, calcium channel blocker and aldosterone antagonist. The participants will be observed under the BP management for their respective BP target. The study will be continued until the number of patients with the first recurrent stroke reaches a total of 330 between two groups. The follow-up period will be 3 years. The recurrent rates of stroke in both groups will be compared from various aspects, and strict BP management will be investigated on the usefulness in prevention of recurrent stroke.
Stroke is the leading cause of mortality in Brazil. Strict blood pressure control in chronic phase is the major measure to primary and secondary prevention, but in acute phase is not clear the best blood pressure level. Few studies demonstrate a "U" relationship between blood pressure and lethality; nevertheless any Brazilian study has addressed this issue. This is a prospective observational study on the relationship between BP and mortality in the acute phase of stroke. The study will be conducted in the Adult ICU of HC-UNESP. Will be analyzed 266 patients aged 18 years and of both sexes admitted to the ICU with a diagnosis of hemorrhagic and ischemic stroke. Participants will be divided into three groups according to the initial PA present: Group A: Patients with systolic BP of entry below 140 mmHg; Group B: Patients with systolic BP of entry between 140 and 180 mmHg; Group C: patients with systolic BP greater than 180 mmHg entry. Multiple logistic regression analysis will be done to verify the association of blood pressure and lethality adjusted to confounding variables.
Background: - Previous research has shown that certain parts of the brain are involved in voluntarily stopping an ongoing motor response (movement); however, it is not known whether this same network is also involved in suppressing an urge to act. Traumatic brain injury (TBI) can significantly impair the brain's ability to voluntarily stop or inhibit certain actions. Using brain imaging (functional magnetic resonance imaging, or fMRI) and brain stimulation (transcranial magnetic stimulation, or TMS) to investigate how people perform activities that involve moving and suppressing movements, researchers hope to better understand how these brain areas might be affected in people who have had TBI. Objectives: - To determine the parts of the brain involved in suppressing an urge to act. - To determine the extent to which traumatic brain injury affecting certain parts of the brain is involved in problems with suppressing an urge to move and stopping movement. Eligibility: - Individuals 18 to 40 years of age who have had mild or moderate TBI, or are healthy volunteers. Design: - This research study includes a screening visit and two study visits, each of which will last at least 2 hours. - Participants will be screened with a physical examination and medical history. Women who can become pregnant will have a urine pregnancy test before being allowed to participate in the study. - At the first study visit, participants will complete one of the following experiment tests in an MRI scanner. - Experiment 1: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will practice the experiment tasks before performing them during MRI scans. - Experiment 2: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will also have TMS while at rest, and will perform the experiment tasks during the MRI scan. - At the second study visit, participants will have an fMRI scan where they will be asked to do simple response tasks with a computer outside the MRI scanner.

This study will assess the effects of an intervention targeting family caregivers who recently placed a relative in a long-term care facility because of cognitive and/or physical disability. In a two group randomized clinical trial we predict that caregivers assigned to active treatment will have lower levels of depressive symptoms, anxiety symptoms, and greater satisfaction with the long-term care facility when compared to individuals assigned to the control condition.
The purpose of this study is to evaluate whether persons with stroke participating in a 12-week community based wellness program for persons who have had a stroke, experience improved mobility (6 Minute Walk Test), balance, (The Short Portable Performance Test and Timed Up and Go), strength (JAMAR hand grip dynamometry), level of physical activity (Rapid Assessment of Physical Activity), reintegration in community (Reintegration into Normal Living Index), self efficacy (Patient Activation Measure) and Quality of Life (Stroke Specific Quality of Life Scale) compared to persons who do not participate in the program.
