Active clinical trials for "Stroke"

The objective is to evaluate decision making of i.v. tPA treatment in acute stroke within 3 hours of symptom onset either remotely via videoconferencing system (investigational arm) beginning of treatment on-site and then transfer to stroke unit vs. decision after immediate transfer to stroke unit (usual care arm). Ten remote hospitals are connected to the BICHAT stroke unit. All patients will have stroke unit care at BICHAT hospital. Primary end-point is rankin 0-1 at 3 months.

In this multi centre pilot study we will perform TEE in patients with AF who are eligible for VKA treatment. TTE will be used as pre-screening: if TTE shows left atrial abnormalities or aortic plaque, patients will be excluded from randomisation. TEE will be performed in all other patients to detect or exclude complex aorta plaques or signs of left atrial stasis. Three hundred patients who do not have these features on TTE will be randomly assigned to treatment with aspirin or VKA. Follow-up will be 1 year.

Interventional study with minimal risks and constraints, prospective, monocentric.

The purpose of this research study is to show that a computer can analyze brain waves and that those brain waves can be used to control an external device. This study will also show whether passive movement of the affected hand as a result of brain-based control can cause rehabilitation from the effects of a stroke. Additionally, this study will show how rehabilitation with a brain-controlled device may affect the function and organization of the brain. Stroke is the most common neurological disorder in the US with 795,000 strokes per year (Lloyd-Jones et al. 2009). Of survivors, 15-30% are permanently disabled and 20% require institutional care (Mackay et al. 2004; Lloyd-Jones et al. 2009). In survivors over age 65, 50% had hemiparesis, 30% were unable to walk without assistance, and 26% received institutional care six months post stroke (Lloyd-Jones et al. 2009). These deficits are significant, as recovery is completed after three months (Duncan et al. 1992; Jorgensen et al. 1995). This large patient population with decreased quality of life fuels the need to develop novel methods for improving functional rehabilitation. We propose that signals from the unaffected hemisphere can be used to develop a novel Brain-Computer interface (BCI) system that can facilitate functional improvement or recovery. This can be accomplished by using signals recorded from the brain as a control signal for a robotic hand orthotic to improve motor function, or by strengthening functional pathways through neural plasticity. Neural activity from the unaffected hemisphere to the affected hemiparetic limb would provide a BCI control in stroke survivors lesions that prevent perilesional mechanisms of motor recovery. The development of BCI systems for functional recovery in the affected limb in stroke survivors will be significant because they will provide a path for improving quality of life for chronic stroke survivors who would otherwise have permanent loss of function. Initially, the study will serve to determine the feasibility of using EEG signals from the non-lesioned hemisphere to control a robotic hand orthotic. The study will then determine if a brain-computer interface system can be used to impact rehabilitation, and how it may impact brain function. The system consists of a research approved EEG headset, the robotic hand orthotic, and a commercial tablet. The orthotic will be made, configured, and maintained by Neurolutions. Each participant will complete as many training sessions as the participant requires, during which a visual cue will be shown to the participant to vividly imagine moving their impaired upper extremity to control the opening and closing of the orthotic. Participants may also be asked to complete brain scans using magnetic resonance imaging (MRI).

The purpose of this study is to identify and establish how the area of the brain that controls motor function (motor cortex) of the non-affected hemisphere after stroke might serve as a new target for therapeutic interventions to improve motor performance after stroke.

The aim is to study effects of touch massage in the sub-acute phase after stroke in two main areas; general health and independence.The hypothesis are that; touch massage in the sub-acute phase after stroke decreases anxiety and pain, increases health related-quality of life, decrease physiological stress responses, increase sensorimotor function, decrease disability, and increase activity in sensorimotor areas and decrease redundant brain activity in motor-related areas.

The purposes of this study are to determine the effectiveness of an interactive stroke educational program compared to standard educational materials and usual care, to increase stroke knowledge, and to improve emergency room arrival times upon onset of stroke symptoms.

The purpose of this study is to examine how different areas in the brain interact with each other and how using brain imaging and brain stimulation approaches can influence these interactions.

Although the mirror therapy is recognized as effective, its practice is difficult, especially with hemiplegic patients. It is difficult for them to understand, control the movements and carry out a double task with the two upper limbs. The implementation of a Computerized Mirror Therapy (CMT) with the Intensive Visual Simulation 3 (IVS3) device makes it possible to limit these problems by proposing pre-recorded sessions, not limited to the right or left hemi-space, and proposing a work on proximal motricity. Since the functional prognosis of the upper hemiplegic limb remains mostly unfavourable, a wide range of interventions should be proposed. There is currently a consensus to consider the use of transcranial Direct Current Stimulation (tDCS) stimulation in functional recovery after stroke as a method to enhance the effectiveness of training techniques. Although all motor therapies can theoretically benefit from increased effectiveness by the addition of transcranial Direct Current Stimulation (tDCS), Computerized Mirror Therapy (CMT) has a high potential for sensitivity to transcranial Direct Current Stimulation (tDCS) due to the intensity of the motor training of the upper limb applied.

Medical progress and modification of lifestyles have prolonged life expectancy, despite the development of chronic diseases. The support and care are often provided by a network of informal caregivers composed of family, friends, and neighbors. They became essential to help maintening the elderly persons to live at home. It has been demonstrated that the importance and the diversity of informal tasks may jeopardize their own physical, mental and social well-being. The aim of the Informal Carers of Elderly Cohort is to define, through a longitudinal study of their life course, the profiles of caregivers of patients with a diagnosis of one of the following diseases: cancer (breast, prostate, colon-rectum), neuro-degenerative diseases (Parkinson's disease, Alzheimer's and similar diseases), neuro-vascular diseases (Cerebrovascular Accident (CVA)), Age-related Macular Degeneration(AMD) and heart disease (heart failure), aged ≥ 60 years old and living in Burgundy or Franche-Comte. By following the different phases of the caregiving relationship from the announcement of the diagnosis, it will be possible to assess the quality of life of caregivers and evaluate the implementation of a pragmatic social action to help informal caregivers through a randomized intervention trial nested in the cohort. Thanks to an analytical and longitudinal definition of the profiles of informal caregivers, this study could gather precise information on their life courses and their health trajectory by identifying the consequences associated with the concept of their role of aid in care. In addition, the randomized intervention trial will explore the efficacy, in terms of quality of life, and efficiency of a social action to support the caregivers. These data will allow to identify strategies that could be used to improve the existing sources of aid and to propose new approaches to help caregivers. This study will provide the opportunity to identify the most relevant means of support and to give an impulse for new healthcare policies.
