Filter by:The purpose of this study is to evaluate the effectiveness of a rehabilitation (physiotherapy) program in patients with acute ischemic stroke in Acute Vascular Unit and in general ward of Hospital de Clínicas de Porto Alegre, and to verify the degree of disability at fourteenth and third month, functional improvement at third month, the frequency of deaths and incidence of complications due to immobility and quantify the time spent in hospital.
The study is to assess the safety and possible efficacy of umbilical cord blood mononuclear cells (UCBMC) treatment of chronic ischemic stroke.
Elevated body temperature was shown to be associated with worse outcome in acute stroke patients. PreCOOL 1 aims to investigate efficacy, feasibility and safety of prehospital cooling with cold infusions in stroke patients.
Negligence or contempt of the etiology and pathogenesis of minor ischaemic stroke in the early diagnosis and effective treatment leads to more than 40-50% of patient with recurrent episodes, and 10% patient died. Therefore, diagnosis and treatment of minor ischaemic stroke according to the etiology and pathogenesis is important. The 2007 Korean modified TOAST type got some progress, but there exists two major disadvantages: imperfect diagnosis and pathogenesis of perforator artery infarction etiology; lack of typing according to the pathogenesis of large atherosclerotic infarction and taking measures of treatment according to the new types. Recently, domestic professor Gaoshan proposes new approach to diagnose and treat minor ischaemic stroke according to the etiology and pathogenesis of CISS typing, but the pathogenesis of hypoperfusion infarction with severe stenosis of large artery is unclear. Is it low perfusion? Or artery-artery embolization? Or both? How to distinguish the pathogenesis of branch artery disease: by atherosclerosis? Or hyalinosis? Or both? How to check the validity of clinical types? This study take different interventions according to different types and observation of the long term clinical results of intervention( mortality, recurrence rate, disability rate and rate of cerebral hemorrhage and subarachnoid hemorrhage), in order to clarify the new types can indeed solve the current problem of minor ischaemic stroke with high mortality, recurrence rate, disability rate and rate of cerebral hemorrhage and subarachnoid hemorrhage.
This is an open-label brain PET/CT (positron emission tomography/computed tomography) study to investigate the diagnostic performance of 68Ga-BNOTA-PRGD2 in evaluation of stroke patients in convalescence. A single dose of nearly 111 MBq 68Ga-BNOTA-PRGD2 ( ≤ 40 µg BNOTA-PRGD2) will be intravenously injected into the patients. Visual and semi-quantitative method will be used to assess the PET/CT images. Changes of 18F-FDG PET/CT, enhanced brain MRI or CT, and any adverse events will be collected from the patients.
The purpose of this proposal is 1) to compare the relative effects of the robotic rehabilitation (RR), mirror therapy (MT), and conventional intervention (CI), 2) to compare the effects of the combined therapy of the RR-Functional Electrical Stimulation (FES) and the RR-Placebo Intervention (PI), and 3) to identify the clinical predictors that will potentially influence the functional outcomes after interventions.
The overall goal of the study is to evaluate the clinical effectiveness of a home-based tele-motion-rehabilitation (TMR) program in improving functional status of people who had stroke. We hypothesize that the clinical effectiveness within a mock-up set up in the hospital of the TMR will be greater in comparison to self-training exercise carried out at home in improving outcomes of Range of Motion and functional performance of the weak upper extremity. Twenty-four subjects who had a stroke, aged between 18 and 80 years, and living at home will participate. Subjects will be 2-72 months post stroke, and no longer receiving rehabilitation as in or out patient. They will have moderate impairment of the affected upper extremity determined by range of motion (ROM). Subjects will be evaluated for motor and cognitive abilities for a total of 5-6 hours by a skilled therapist who will be blind to group's assignment of the subjects. The evaluations will be repeated 3 times, once before the intervention commences, once immediately following the intervention and once four weeks after the intervention. Subjects will be randomized into the two groups (TMR versus self-training treatment) with matching for level of impairment of the upper extremity by a person who is not part of the study. Each subject will receive twelve 45-60 min sessions over 4 weeks while seated. The control group will receive self-training exercises that are based on conventional therapy using principles of motor control and will include training of upper extremity movements in order to achieve better use of the affected arm in ADL. The experimental group will receive TMR treatment of comparable duration and intensity to those in the conventional treatment group with remote online monitoring by the therapist. Treatment feedback will be given in the form of Knowledge of results (game scores) and Knowledge of performance (feedback of compensatory movements made while using the upper extremity) to enhance motor learning. The software will generate a report which will include the duration and type of exercises performed by the subject. The Gertner TMR system is implemented via Microsoft's Kinect three-dimensional) camera-based gesture recognition technology. Using the patient's natural hand and body movements control all activity within customized computer games. The system runs off a standard desktop computer and is displayed on a large television screen.
Rehabilitation after stroke improves motor functions by promoting plastic changes however, after completing standard rehabilitation, 50-60% of patients still exhibit some degree of motor impairment and require at least partial assistance in activities of day living. Therefore, the exploration of other approaches to promote recovery is compulsory. Non invasive brain stimulation and motor rehabilitation are thought to share similar mechanisms in inducing neuroplastic changes in the human cortex and an emerging field of research is focusing on the possibility of coupling both therapies in order to achieve an additive effect and improve outcome. We hypothesize that coupling bihemispheric transcranial direct current stimulation (tDCS) with simultaneous physical/occupational therapy in the subacute phase of ischemic stroke patients may improve upper limb motor recovery in humans. This is a randomized, controlled, double blind, cross-over, multicentre, clinical trial. Thirty-six ischemic stroke patients in the subacute phase will be recruited in three centers of neurorehabilitation in Switzerland. After stratification based on the Fugl-Meyer Assessment Upper Extremity according to the severity of the deficit, the patient will be randomized to receive besides standardized physical/occupational treatment according to the Impairment-Oriented Training, tDCS of themotor cortex (1.5 mA, 30 minutes) (group 1: 12 patients) or sham stimulation (without current) (group 2: 12 patients). After three weeks of treatment group 1 and 2 will cross-over and will be treated for other three weeks. Group 3 (12 patients) will receive routine physical/occupational treatment and sham tDCS for six weeks. Assessment will be performed before starting tDCS, at week 3, 6 and at 6 months. Outcome measures are the Fugl-Meyer Assessment Upper Extremity, the extended Barthel Index, the Ashworth scale, the Test of Upper Limb Apraxia (only baseline, week 6, month6), the grip strength evaluated by the Jamar Hydraulic Hand dynamometer. At baseline at week 6 and at month 6 depression will be assessed by the Hamilton depression Rating Scale.
The primary objective of this study is to evaluate the safety of intravenous tPA in patients waking up with symptoms of acute stroke and presenting to the ED within 4.5 hours from awakening, and meeting standard criteria for treatment with IV tPA for acute stroke. The hypothesis is that patients that wake up with stroke symptoms may have developed the stroke at the time of awakening, and may be within the 4.5 hour window if they arrive to the ED within that time, therefore IV tPA should be safe and effective in this population.
The purpose of this study is to evaluate the safety and efficacy of the induced hypertension using phenylephrine in patients with noncardioembolic ischemic stroke. The investigators hypothesized that phenylephrine induced-hypertension can result in good clinical response without serious complications in patients with noncardioembolic ischemic stroke.
