Validation of Early Prognostic Data for Recovery Outcome After Stroke for Future, Higher Yield Trials...
StrokeStroke4 moreVERIFY will validate biomarkers of upper extremity (UE) motor outcome in the acute ischemic stroke window for immediate use in clinical trials, and explore these biomarkers in acute intracerebral hemorrhage. VERIFY will create the first multicenter, large-scale, prospective dataset of clinical, transmagnetic stimulation (TMS), and MRI measures in the acute stroke time window.
Bio-Repository of DNA in Stroke: an Epidemiological and Genetic Study
StrokeStroke2 moreThe Bio-Repository of DNA in Stroke (BRAINS) recruits all subtypes of stroke as well as controls from two different continents, Europe and Asia. Subjects recruited from the United Kingdom (UK) will include stroke patients of European ancestry as well as British South Asians. Stroke subjects from South Asia will be recruited from India and Sri Lanka. Subjects are also recruited in Qatar. South Asian cases will also have control subjects recruited.
Exploring Accessible Beauty for Individuals With Upper Extremity Deficits
StrokeIschemic14 moreThe purpose of this study is to investigate the accessibility of beauty products for individuals with upper extremity disabilities. By examining various factors such as packaging design, product applicators, and ease of use, this research aims to identify barriers faced by individuals with upper extremity disabilities or visual deficits when using beauty products. The study seeks to provide insights and recommendations for improving the accessibility of beauty products, ultimately promoting inclusivity and enhancing the overall beauty experience for individuals with disabilities.
Prognosis and Diagnosis of Spasticity in Acute-post Stroke Patients
StrokeAcute4 moreSpasticity, or greater muscle resistance, is a major disabling condition following stroke. Recovery of lost motor function in patients with stroke may be affected by spasticity, which most commonly develops in elbow and ankle muscles. However, despite its clinical relevance, the natural development of spasticity over the first 3 months after stroke is not clearly understood. Indeed, common clinical measures of spasticity such as the Modified Ashworth Scale (MAS) do not take into account the neurophysiological origin of spasticity and lack reliability and objectivity. The objective of this study is to examine the natural history of the development of spasticity among patients with stroke over the first 3 months using a new neurophysiological measure (TSRT, the tonic stretch reflex threshold angle) and its velocity sensitivity (mu) in comparison to MAS and other common clinical tests. In addition, detailed brain imaging will be used to understand the relationship between damage to brain regions relevant to the development of spasticity and TSRT/mu values. It is hypothesized that 1) TSRT/mu will indicate the presence of spasticity earlier than MAS/clinical tests; 2) TSRT/mu measures will be more closely related to motor impairments and activity limitations than MAS; 3) the lesion severity (identified by imaging) will be related to the change in TSRT/mu values. Outcomes will be measured in a pilot cohort of 12 patients hospitalized for first-ever stroke. Measurements will be taken at the bedside within the 1st week of the patient's admission and will be done once per week for 12 weeks with a follow-up at week 16. Brain Imaging will be done around the 6th week post-stroke.
Urinary Disorders in Subacute Patients After Stroke
StrokeIschemic2 moreThis observational study will address urinary disorders in subacute stroke patients. Patients without and with urinary disorders will be compared, and treatment outcome will be assessed among the latter.

Correlation Between Intestinal Microecology Imbalance and Stroke in Young Adults
Ischemic StrokeHemorrhagic StrokeThe relationship between the intestinal microecology and stroke has become a research hotspot in neurology field today. Maintaining the balance of the intestinal microbiota are expected to bring new breakthroughs for prevention and treatment of stroke. In recent years, stroke in young adults has an increasing incidence and a considerable socioeconomic impact because of high disability rate and health-care costs. So there is an urgent need to explore the role and mechanism of intestinal microecology imbalance in stroke, especially in the development and prognosis of stroke in young people. This study aims to use multi-omics technologies, including microbial diversity, metagenomics and metabonomics, to reveal the characteristics of intestinal flora in young stroke patients, identify biomarkers for predicting outcome after stroke and early detection of young people at high risk of stroke, and to further explore the role of gut-brain axis in the pathogenesis of stroke.
FIND Stroke Recovery - A Longitudinal Study
StrokeStroke Hemorrhagic5 moreStroke survivors frequently suffer disabilities including motor and cognitive problems, impairments in speech and vision, depression, and several other disabilities that worsen their quality of life. Some will recover fully after stroke and others will have permanent impairments. Few studies show trajectories of recovery in different domains after stroke, hence recovery time-lines are not fully known. Also, the whole range of mechanisms leading to recovery are not precisely known (1). To monitor those mechanisms one can utilize biomarkers. In parallel to the studies of recovery, studies on time series of biomarkers after stroke are limited (2). Hence, a crucial first step to increase knowledge on biomarkers of stroke recovery is to gain a better understanding of the time course of both stroke recovery and biomarker patterns. Biomarkers can later be used for outcome predictions after stroke.
Stroke Recovery Initiative - Registry for Stroke Research Studies
StrokeAcute Stroke7 moreThe Stroke Recovery Initiative is a nation-wide participant recruitment registry that connects people who have had a stroke with researchers who are working to develop new approaches to improve recovery after stroke.
