NCT ID: NCT03119116 Active, not recruiting - Stroke Clinical Trials

Use of Direct Oral Anticoagulants in UK

Start date: May 15, 2017
Phase: N/A
Study type: Observational

Many people who suffer from irregular heartbeats (atrial fibrillation) which might cause stroke, need to take blood thinners to prevent it. It is important to prescribe the correct dose of blood thinners to the right patients to ensure the treatment works however avoiding complications. In the recent years, new blood thinners have been available; they require less laboratory tests and fewer visits to a doctor compared to older therapies. This study will look at how the general practitioners in the UK prescribe blood thinners according to the instructions given by the product manufacturer. We will use primary care data that is routinely collected by the general practitioners about their patients but without any possibility to identify individual patients. The results will help us to understand the magnitude of deviation from instructions in order to ensure that the patients benefit from the treatment.

NCT ID: NCT03080233 Active, not recruiting - Stroke, Acute Clinical Trials

Validation of Clinical Decision Support Tool for Acute Stroke Diagnosis (InstaDx)

Start date: February 1, 2017
Phase: N/A
Study type: Observational

This is a observational validation study. The Stroke Clinical Decision Support Tool ( InstaDx) , an information technology application will be adapted and developed in accordance to evidence based clinical practice guidelines ( Level IA). Neurology Residents will be using the InstaDx CDST to improve their diagnostic accuracy and the findings will be validated against the review of a stroke subject expert. The study hypothesis is that Clinical Decision Support Tool used by neurology residents will have an agreement of >0.77 when compared to Stroke Expert (gold standard) in diagnosing type of ischemic stroke.

NCT ID: NCT03023150 Active, not recruiting - Clinical trials for Ischemic Preconditioning

Ischemic Preconditioning as an Intervention to Improve Stroke Rehabilitation - Froedtert

Start date: October 2016
Phase: N/A
Study type: Interventional

This study will be the first study to use ischemic preconditioning (IPC) as an intervention to improve stroke rehabilitation. IPC is a well studied, well tolerated intervention which has been shown to improve regional blood flow, motor neuron excitability and muscle function in multiple patient groups and in young, healthy subjects. Because IPC targets three physiological systems which are all affected by stroke, we hypothesize that repeated bouts of IPC during the first days to months following stroke (when the majority of recovery occurs) will make traditional rehabilitation strategies more effective.

NCT ID: NCT02921360 Active, not recruiting - Stroke Clinical Trials

Early Administration of Aspirin in Patients With Acute Ischemic Stroke Treated With Systemic Thrombolysis

Start date: August 2016
Phase: N/A
Study type: Interventional

The aim of this study is to determine whether early administration of aspirin in acute ischemic stroke patients treated with systemic thrombolysis is safe and can improve outcomes due to decreasing the number of early rethromboses.

Phase: N/A
Study type: Interventional

- Are there differences in immediate effects of stepping training with and without the use of visually weight-taking machine (VWTM) on variables relating to well-controlled walking and walking symmetry in ambulatory patients with stroke? - Are there differences of 4-week stepping training with and without the use of VWTM on variables relating to well-controlled walking and walking symmetry in ambulatory patients with stroke?

NCT ID: NCT02881736 Active, not recruiting - Chronic Stroke Clinical Trials

Proprioceptive Deficits and Anomalies in Movement-error Processing in Chronic Stroke Patients

Start date: October 2013
Phase: N/A
Study type: Interventional

Clinical assessment of motor and sensory deficits is still today largely based on tests that do not permit any precise quantification. However, robotic technologies, coupled with neuroimaging techniques constitute new tools to assess sensorimotor functions that could allow to conceive neurorehabilitation protocols better adapted to the neurological impairment of each patient and to her/his specific recovery profile. The goal of this project is to contribute identifying the factors that determine functional recovery in stroke patients presenting upper-limb motor deficits. Here, we will focus our research on two factors that contribute in a complementary way to motor control: 1) the processing of proprioceptive informations, and 2) the processing of movement-execution errors. In this purpose, we will combine psychophysical methods that allow to precisely quantify sensorimotor deficits with functional and anatomical neuroimaging techniques. More specifically, we will exploit experimental protocols that have been developed in basic research, that use a robotic exoskeleton coupled with a virtual reality device, to precisely quantify motor and proprioceptive deficits in stroke patients. Then, we will link these behavioral data to electroencephalographic (EEG) signals recorded during a motor adaptation task, as well as to anatomical data, namely conventional magnetic resonance imaging (MRI) completed by diffusion tensor images (DTI) in order to achieve a finer description of the cerebral lesions. The present study will include two experimental parts, respectively centered on the proprioceptive deficits (Part 1) and the anomalies in the processing of movement-execution errors (Part 2). Proprioceptive deficits in stroke patients : We will test the hypothesis that, when present, deficits in kinaesthesia and troubles in unconscious proprioception contribute substantially to motor deficits in stroke patients ; with as a corollary hypothesis, that deficits in " proprioception for action " are more determinant than deficits in the conscious sense of position (classically tested in clinics). In this purpose, we will collect three sets of behavioral data, in chronic stroke patients and healthy control participants, respectively intended to assess a) motor deficits, b) troubles in conscious sense of position, and c) deficits in "proprioception for action". To better document the neuronatomical substrates of these different types of deficits. In this purpose, we will link the obtained behavioral data with the results of detailed analyses of the lesions of the tested stroke patients. Anomalies in the processing of movement-execution errors in stroke patients : We will assess movement-execution error processing in stroke patients, in order to test the idea that anomalies in error processing might contribute to motor deficits in stroke patients. In this purpose, we will record an electrophysiological correlate (ERP) of movement-error processing during a motor adaptation task. We will analyse the relation between the modulation of this ERP and motor performance. We will also examine the relation between these two sets of data (behavioral and electrophysiological) and the behavioral data collected during the first part of the study (Proprioceptive deficits). This will provide us with insight into the relationship between proprioceptive deficits and cinematic error processing. As in the first part of the study, we will link the observed electrophysiological and behavioral anomalies with the results of a detailed analysis of the anatomical lesions of the tested patients.

NCT ID: NCT02830945 Active, not recruiting - Stroke Clinical Trials

Innovative Multigenerational Household Intervention to Reduce Stroke and CVD

Start date: July 1, 2015
Phase: N/A
Study type: Interventional

American Indians (AI's) are experiencing an epidemic of stroke morbidity and mortality, with higher prevalence and incidence, younger age at onset, and poorer survival than other racial and ethnic groups. With a stroke incidence more than twice that of the general U.S. population, stroke in AI's is a public health problem of staggering scope. AI's also have disproportionate burdens of many risk factors for stroke, including hypertension, smoking, obesity, and diabetes. However, no rigorous, population-based studies of stroke prevention have included AI's. The investigators at WSU, and community partners, have designed the "Family Intervention in the Spirit of Motivational Interviewing" (FITSMI), a program delivered at the household level to encourage lifestyle changes that transform the home environment and reduce stroke risk for all residents. FITSMI uses a "talking circle" format in which facilitators guide participants to identify goals for change and create a tailored plan for sustainable implementation that may target smoking, exercise, diet, or medication adherence. FITSMI requires just 2 sessions (baseline and 1 month post-baseline), with text messaging used to boost long-term adherence. In a group-randomized trial design, the investigators will recruit 360 households where Strong Heart Family Study members aged 45 and older reside. The investigators will assign half to FITSMI and half to a control condition that receives educational brochures.
