Filter by:A prospective observational cohort study in patients with cerebral small vessel disease deterring whether changes in systemic inflammation predict brain white matter damage measured using MRI and cognitive decline. This is a study funded by a joint BHF-Dutch Heart Foundation research grant and will be conducted in both Cambridge UK and Nijmegen Netherlands with 100 of the 200 total participants recruited at each site, and data from both sites analysed together.
The trial is prospective, randomized, open-label, blinded endpoint (PROBE) design. Patients with acute ischemic stroke, who are eligible for standard intravenous thrombolysis within 4.5 hours of stroke onset will be randomized 1:1 to 0.25mg/kg or 0.9 mg/kg alteplase before all participants undergo endovascular thrombectomy.
The purpose of this study is to demonstrate the effectiveness and safety of CVA-FLOW, a digital health AI based Telestroke system developed by CVAID Ltd. Company aims to assist certified medical staff to triage acute ischemic stroke patients using dedicated algorithms in order to support application for market approval for CVA-FLOW device.
Falls are an "emerging public health crisis" that cost the Canadian health care system billions of dollars each year. Moreover falls have a significant, detrimental impact on the lives of those who fall. In addition to physical injury and hospital admission, individuals may experience a post-fall syndrome characterized by dependence, depression, and reduced mobility and participation. Individuals living with the effects of neurological disease or injury are at a particularly high risk of falling. For example, 69-78% of individuals with spinal cord injury or disease (SCI/D) and 73% of individuals post-stroke fall at least once per year. Despite this high fall risk, evidence-based initiatives to prevent falls among those with SCI/D or stroke are lacking in neurorehabilitation. Furthermore, little time is dedicated to improving balance during inpatient neurorehabilitation. For example, ambulatory inpatients with SCI/D spend, on average, a mere 2.0±2.0 hours on balance training over the course of their entire inpatient stay. Our team is developing effective solutions to the "high-volume, high-risk and high-cost challenge" of falls. Our long-term objective is to develop an intervention that improves balance in a clinically meaningful and feasible way, facilitating the recovery of safe upright mobility and addressing the current health crisis of falls in individuals living with neurological disease or injury. The intervention will be developed with a focus on neurological populations, as these patient groups have a critical need for balance training; however, the intervention will be transferrable to other populations at risk of falls, such as older able-bodied adults. A probable solution to the gap in balance interventions is functional electrical stimulation (FES), whereby an electrical current is applied to peripheral nerves to facilitate muscle contractions. By applying the appropriate amount of electrical stimulation at the appropriate time during movement execution, the central nervous system can be re-educated, facilitating motor and functional improvements. The investigators developed a closed-loop FES system whose controller mimics the physiological control system. By combining this system with visual feedback balance training (VFBT), the investigators developed a prototype system of FES and VFBT (FES+VFBT). This intervention involves standing on a force plate with one's centre of pressure (COP) presented on a monitor. As the user moves his/her COP in response to a game, FES is delivered to the plantarflexor and dorsiflexor muscles through the device, MyndSearch.
The main goal will be to evaluate the effect of improving the quality of movement of the upper limb (using an evaluation exercise in the software of the Armeo Spring device) on the development of the quality of life after stroke using a standardized generic and specific questionnaire. The secondary outcome will be to evaluate changes in self-sufficiency using a test of daily activities modified by the Frenchay test of daily activities.
The purpose of this study is to determine the efficacy and safety of levofloxacin combined with intravenous thrombolysis in treating acute ischemic stroke
Cerebrovascular accident is the 2nd leading cause of death and the leading cause of disability in the world. There are brakes and levers of medication adherence in the context of secondary prevention treatment in stroke.
This is a device study that will evaluate the effect of an implanted stimulator on improving walking in stroke survivors. There are two phases in the study: 1) Screening - this phase determines if the individual is a good candidate to receive an implanted system, 2) Implantation, controller development, and evaluation - this phase includes installing the device and setting the individual up for home use, creating advanced controllers for walking and evaluating the effect of the device over several months.
Background: Stroke is a leading cause of adult disability. The ability to walk is considered as the most important physical activity in daily life and strongly associated with quality of life in patients with stroke sequela. Conventional transcranial Direct Current Stimulation (tDCS) can induce mixed effects to improve gait impairment after stroke. The problem of limited focal specificity of tDCS may lead to an ineffective stimulation and in turn may be reduced the potential application of tDCS in clinical routine. High-definition transcranial Direct Current Stimulation (HD-tDCS) allows inducing, in a non-invasive way, a transient excitatory neuromodulation of a given cerebral region and to obtain a very focused cortical effect. However, the clinical and neurophysiological effects of HD-tDCS remain largely unknown for enhancing gait recovery in patients with stroke. The investigators hypothesize that anodal HD-tDCS will enhance neural interactions between motor networks and, thereby, improve motor processing and gait relearning. The investigators propose to carry out a study on chronic stroke patients involving anodal HD-tDCS of the affected primary motor cortex combined with a physical therapy. This study has three main objectives: - To compare the effects of two techniques of tDCS (anodal tDCS, anodal HD-tDCS) on clinical recovery in patients with chronic stroke. - To assess the effects of these brain stimulation techniques on brain reorganization with electroencephalography (EEG). - To assess the effects of these brain stimulation techniques on spatiotemporal gait parameters during walking with wearable motion sensors. Methods: 36 patients with ischemic or hemorrhagic stroke will be randomly assigned to one of 3 groups: anodal tDCS, anodal HD-tDCS, or sham stimulation. Each group will receive the corresponding stimulation therapy 3 times per week for 2 weeks, simultaneously with physical therapy. Before (T0) and immediately after the treatment period (T1) and again one month later (T2), standardized assessments of sensorimotor function areas are obtained together with spatio-temporal analysis. Brain reorganization is assessed with EEG before and immediately after the treatment period. These recordings will be used to compare and investigate the clinical and physiological effects of each treatment modality.
There is an urgent need for educational and psychological adjustment to stimulate the post-stroke patients' motivation to actively carry out rehabilitation. Studies have shown that interventions based on character strengths are widely used in chronic disease patients abroad, and have achieved the effect of improving the physical and mental health. However, research on individualized character strengths in stroke patient intervention is limited, and more clinical evidence is needed. This study is based on personality theory and the application of character strengths-based STEP programme (CSSTEP) in stroke patients. The investigators hypothesized that the CSSTEP programme could help stroke patients to improve mental state, cognitive function, and better gait performance, suffer from less post-stroke depression, enhance their post-stroke self-confidence.
