Filter by:More than one million people in Europe suffer from a stroke every day. Normally older people have a stroke, but also a significant number of younger people between 18 and 55 years. Usually, these can only be explained for a minority by the classical risk factors such as diabetes, overweight and high blood pressure. New studies indicate that in about 1 - 2 % of the younger stroke patients the etiology can be an undiagnosed genetic disease, e.g. Fabry disease. Fabry disease is a lysosomal storage disorder known to cause vasculopathy. The purpose of this study is to determine in a large number of young stroke patients, how many strokes were caused by Fabry disease and what risk factors might be able to predict this disease.
The main purpose of the study is to get information about the safety and efficacy of treatment with Dapsone to prevent the disability after ischemic Stroke, in patients diagnosed with anterior territory brain infarct.
Reduced mobility and increased fall risk are significant long-term health problems facing those who have persistent weakness or paralysis in their legs resulting from stroke. Recent innovations in post-stroke therapy have applied motor learning principles to improve motor skills through regular practice of activities using the weaker limb. Because the ankle is so critical in providing forces for normal walking and balance function, impairments at the affected ankle pose a major limitation to achieving optimal rehabilitation outcomes. To address this we have developed a novel ankle robot (Anklebot) to enhance physical therapy for improving walking and balance functions after stroke. It is a computer controlled exercise machine that can be worn during walking or in a seated position for practice with video games. The Anklebot controllers allow for assisting users when they cannot complete a movement, or resisting movement, or simply recording movements and forces. Passive movement therapy has shown promise in exciting brain to muscle connections for recovery of walking function; however it does not appear to yield optimal results, suggesting that active involvement in task-oriented therapy is essential. Not only is voluntary movement important to initiate this excitation, the brain mechanisms of reward and motivation play an important role. These mechanisms have been widely studied in both humans and animals. Core brain networks involved in reward and motivation are designed to increase a person's involvement with their surroundings, to focus attention and to prompt one to approach reward and avoid punishers. These increases in involvement and the elevated emotions that are part of it have been shown to enhance performance, memory and learning. The primary purpose of this pilot study is to investigate responses of brain and muscle activity in stroke patients who use the Anklebot during a 3-week / 3-session/week motor learning based training. These responses will be compared to a 3-week delayed entry period in which the participants will perform an at-home walking program equal in time spent to the time they will spend on the Anklebot during the 3-week / 3x/week training. In Addition, after the 3-week delayed entry walking program the subjects will be divided into low and high reward-feedback groups. The low reward-feedback group will receive the Anklebot training with only immediate feedback (they will know if they succeeded on the current trial but they will never know their cumulative score and they will receive minimal social interaction with research team members. While the high-reward feedback group will know their cumulative scores, will receive controlled but abundant social interaction with the research team and will be eligible for prizes of restaurant and movie coupons during individual training sessions and at completion of the study. This will be done to assess the ability of higher reward conditions to increase recovery beyond that of the Anklebot training alone. To accomplish this subjects with chronic stroke will be divided into the high and low-reward/feedback groups and will then play a series of videogames using the Anklebot, as we noninvasively record brain activity using electroencephalography (EEG) and muscle activity using electromyography (EMG). We will also monitor heart rate using electrocardiograms (ECG). In addition to analyzing brain and muscle information before, during, and after the Anklebot training, we will also assess walking and balance functions immediately before and after the first and last robotic training session and ask the subjects to fill out some standardized questionnaires.
THRACE is a controled, multicenter and randomized trial. The primary objective of this study is to determine whether a combined approach intravenous thrombolysis (IV) + Mechanical thrombectomy is superior to the reference treatment with IV thrombolysis alone, in the 3 hours of onset of symptoms in patients with occlusion of proximal cerebral arteries and with a neurological impairment accident (National Institutes of Health Stroke Scale [NIHSS] ≥ 10). The second objective is to determine the cost-effectiveness of this procedure compared to the standard (IV thrombolysis). The assumption is that the combined approach, by improving the clinical outcome and speed recovery, allows for lower overall costs to the IV thrombolysis in 3 months and less than or at worst neutral to 1 year.
Introduction. - There is a demand for evidence whether treadmill therapy is more efficient than traditional walking training as an intervention for patients with hemiplegia after cerebral stroke. Design. - A randomized controlled trial. Material. - Stroke patients with moderate to severe functional deficits referred to inpatient medical rehabilitation. Method. - Comparing a treatment group receiving treadmill training with body weight support with a treatment group receiving conventional walking training. Study aim: - Investigate whether treadmill therapy is more effective than traditional functional training in restoring walking and transfer in patients with moderate to severe ambulatory deficits after stroke.
Visuospatial neglect is a common neurological symptom which appears following strokes on regions of the right hemisphere of the brain. It affects patient's self representation and awareness of the space, impairing functional rehabilitation and adaptation back to a normal life. The primary purpose of this protocol is to assess the impact of 10 daily sessions of a non-invasive brain stimulation technique, low frequency repetitive Transcranial Magnetic Stimulation (rTMS), applied on the intact hemisphere of the brain to treat post stroke visuospatial neglect at the chronic stage. The hypothesis is that a regime of real but not sham rTMS on the left posterior parietal cortex of the brain will long-lastingly ameliorate visuospatial neglect in stroke patients as revealed by clinical paper-and-pencil and computer-based tests assessing search, detection and discrimination of stimuli presented in different areas of the visual field.
The purpose of this study is to compare the incidence of silent and apparent cerebral embolism between conventional and minimal-invasive transfemoral aortic valve repair.
The hypothesis of the study is that combination of reboxetine/tDCS is more effective in enhancing motor functions of daily life (assessed by the Jebsen Taylor test) as compared to reboxetine and tDCS alone. The protocol is designed as a within-subject, block randomized placebo-controlled double-blind crossover study.
The purpose of the study is to use diffusion tensor imaging (DTI) derived axial diffusivity and susceptibility weighted imaging (SWI) to evaluate the severity of acute ischemic stroke and to predict its functional outcome.
The purpose of this project is to follow first-ever- acute stroke patients from onset, one, two and four years post stroke and study the effect of two different approaches of exercises implemented the first year post-stroke.
