Filter by:The purpose of this research study is to test a new medical device, called SONAS. The SONAS device is a portable, battery-powered ultrasound device to detect strokes in the prehospital environment, such as emergency vehicles (eg. ambulances, helicopters). To demonstrate the safety of the device the goal is test it in a small number of healthy volunteers first. The SONAS device will be used to detect changes in blood flow to the brain through ultrasound, otherwise known as TransCranial Doppler (TCD). To date, the SONAS device has been tested extensively in the laboratory, in animals and in human cadavers. The purpose of the present study is to test the device for safety and efficacy in a small group of healthy volunteers. This study will test the device on 10 healthy volunteers. Each volunteer will have a physical examination, neurological examination, and brain MRI both before and after the TCD test is performed. All of these study procedures will be performed on 1 visit, lasting approximately 5 hours. The brain MRI's will be used to verify the effectiveness of the SONAS device on detecting changes in blood flow to the brain.
The study is to determine the safety of human neural stem cell transplantation for the treatment of paralysis and related symptoms due to chronic motor stroke and to determine the maximum tolerated dose.
Stroke is one of the main causes of acquired adult disability in the UK. Many psychological problems can also occur post-stroke; this has a marked impact on health service usage. As such, there is an outstanding need to increase and improve psychological resources within stroke services. The investigators proposed to adapt and evaluate the effectiveness of an acceptance and commitment therapy (ACT) group intervention for adult stroke survivors and their carers. The group will endeavour to promote positive adjustment and reduce levels of depression and anxiety. This study will have two parts.
Stroke places a major burden on health care and society. It often leads to a hemiparesis. Intensive stroke rehabilitation speeds up recovery. In daily practice, the financial and/or human resources to provide this intensive rehabilitation are often lacking. Applying modern-day tracking and feedback technology to encourage a self-administered, context specific training is expected to offer significant potential to increase intensity of practice. Up until now, there has been no randomized trial examining the effect of such an intervention on daily arm usage. The primary objective of this study is to determine the effect of wearing an activity tracking and multimodal feedback device for six weeks on self-reported daily life use of the paretic arm after stroke, when compared to control group stroke subjects wearing a hardware-wise identical sham device providing no feedback. The secondary aim is to examine compliance to use the device and the quantitative, qualitative and functional improvement of the paretic arm. It is hypothesized that participants in the experimental group show a higher change in self-reported daily life use of the paretic arm when compared to the control group both post intervention and at 6-week follow-up. ISEAR is a multicenter, assessor-blinded randomized controlled trial of 62 subjects beyond the first 3 months poststroke.
Stroke is a major public health problem as it is very frequent (140,000 cases/year in France), and very serious (leading cause of death, 2nd leading cause of dementia, 3rd leading cause of handicap). Ischemic cardio-embolic stroke accounts for around 25% of ischemic strokes, and ischemic cardio-embolic stroke in a context of cardiac arrhythmia due to atrial fibrillation (CAAF) is the leading non-atheromatous cause. The aim of this study is to optimise the secondary prevention of CAAF-related stroke identified at the University Hospital of Dijon Burgundy in the framework of the recommendations of the '2010-2014 stroke plan' and the Compulsory Consultation at the 6th month (Directive DGOS//2015/262 of the 3rd August 2015)
This study aims to examine the outcomes of early mobilization and early intervention within 24-72 hours after the onset of hemorrhagic stroke in patients admitted to an intensive care unit within 24 hours after stroke. The patients after hemorrhagic stroke who undergo early intervention only will be compared with those who also receive early mobilization in order to determine if the early mobilization intervention results in earlier or more effective recovery of postural stability, activities of daily living function, or motor capacity. The participants will be randomly assigned to the following two groups: (1) the early mobilization (+early rehabilitation) group and (2) the early rehabilitation group.The measurement parameters will be collected before the intervention (basic parameters), two weeks after the stroke, four weeks after the stroke and three months after the stroke. SPSS (version 17.0) will be used to carry out repeated measures analysis of variance (repeated ANOVA) to compare the differences between the groups at different time points (including basic values and follow-up values). For statistical significance, Bonferroni correction will be applied for the post-hoc analysis of the groups.
This study will evaluate the safety and effectiveness of Respiratory-gated Auricular Vagal Afferent Nerve Stimulation (RAVANS) for improving motor recovery after stroke. Subacute stroke patients will receive RAVANS or sham stimulation concurrent with arm motor training during 10 intervention sessions occurring daily for 30 minutes over 2 weeks. The safety and improvements in arm motor function after the intervention will be compared in patients receiving RAVANS to those receiving sham stimulation.
The purpose of the study are: 1. To make quality, characterized samples and related data available for future studies, including Genome Wide Association Studies (GWAS), genomics, and biomarker research; 2. To use these samples and related medical information to answer research questions aimed at understanding the genetics and underlying biology of acquired disease and injury to the brain, heart and blood vessels with the express purpose of advancing the search for effective modalities for prevention, treatment, and recovery; 3. To develop additional operational infrastructure to support this project across the Prince of Wales Hospital and divisions, including (1) tracking of patient consent, (2) management of collection and sample processing processes, (3) sample inventory and QC/QA processes, and (4) release of materials to investigators for further research.
The effectiveness of robotic over conventional therapy is arguable and the best therapy strategy is still not clear. Basing on the existing evidence on motor learning and practice-induced neuroplasticity, the investigators plan to use an exoskeleton robotic hand to enhance the rehabilitation volume in the subacute stage of stroke patients. The robotic system allows intensive and customized training of hand and finger movements. The aim of this study is (1) to establish whether robot assisted therapy provides any additional motor recovery for the hand when administered during the subacute stage in a Chinese adult population diagnosed with stroke; (2) to evaluate the feasibility and efficacy of robot-assisted hand rehabilitation in improving arm function abilities in subacute hemiplegic patients.
This is a Phase II study to assess the safety and tolerability of DM199 in acute ischemic stroke patients. The study will be randomized, placebo controlled at multiple centers.
