NCT ID: NCT03521882 Recruiting - Stroke, Acute Clinical Trials

Timed Interval Measurement of Eotaxin in Stroke Study

Start date: May 22, 2017
Study type: Observational

Stroke is caused by sudden changes in blood flow in the brain. This can be fatal or can result in permanent disability. A fast diagnosis is essential to initiate effective interventions and optimize benefits to patients. There are other diseases that can look like a stroke and these are called "stroke mimics". The quicker that stroke mimics can be ruled out the faster a stroke can be diagnosed and treatment can be given. We may be able to use chemicals in the blood to rapidly confirm that a person has had a stroke. One such chemical is called eotaxin. Eotaxin has been found to be changed in sufferers of a stroke but not in those with stroke mimics. However, more research is needed to confirm the usefulness of eotaxin. This feasibility study aims to provide the foundations to allow a large scale trial of this test. The study aims to recruit participants that have had a stroke or a stroke mimic from the Acute Stroke Unit and Stroke clinic at the Royal Devon and Exeter Hospital. Up to 6 blood samples will be taken from each participant at different times over one week. Eotaxin will be measured in these samples and in participant's leftover samples taken for clinical care. This is needed because we know that the amount of eotaxin changes in the blood after a stroke but we do not know how quickly this change happens and for how long the change occurs. The study will also allow us to understand how many participants will be needed for a large scale trial and the challenges we may face in recruiting participants.

NCT ID: NCT03520335 Recruiting - Clinical trials for Recognition of Thrombectomy Candidate

Implementation of Finnish Prehospital Stroke Scale to Emergency Medical Services

Start date: April 24, 2018
Study type: Observational

The investigators have developed a simple prehospital stroke scale (FPSS), containing 5 dichotomized items to recognize both large and small artery thrombi of the brain. FPSS is implemented to both emergency medical services and later, to emergency response centers. The efficacy of the scale and possible improvement of both the patient flow and treatment results will be evaluated.

NCT ID: NCT03519828 Active, not recruiting - Clinical trials for Post-stroke Cognitive Impairment

Oxidation-reduction Homeostasis in Cognitive Impairment Patients After Stroke

Start date: March 1, 2018
Study type: Observational

Cognitive impairment after ischemic stroke can affect not only the social adaptation ability, but also affect the comprehensive rehabilitation of patients. The damage of cognitive impairment after ischemic stroke is not lower than the body function defect after stroke. Many studies have shown that oxidative stress is one of the pathophysiological mechanisms of ischemic cerebrovascular disease. Many studies have reported that the oxidative-reduction of cells plays an important role in the life activities of organisms, affecting the health, aging and death of the organism. In the recent years, some scholars have suggested that post-stroke cognitive impairment may be related to oxidative-reduction homeostasis of the body, but the relevant evidence is lacking and needs to be further explored. Therefore, the purpose of this study is to explore the effect of oxidation-reduction homeostasis on cognitive impairment in patients with ischemic stroke, and provide a theoretical basis for the prevention and treatment of cognitive impairment after ischemic stroke.

NCT ID: NCT03519737 Not yet recruiting - Clinical trials for Acute Ischemic Stroke

Aureva Transcranial Ultrasound Device With tPA in Patients With Acute Ischemic Stroke

Start date: May 2018
Phase: Phase 3
Study type: Interventional

This is a randomized, placebo controlled, double-blind phase 3 clinical study to evaluate the efficacy and safety of transcranial ultrasound (TUS) using the Sonolysis Headframe as an adjunctive therapy to intravenous (IV) tissue plasminogen activator (tPA) therapy in subjects with acute ischemic stroke that initially present at non-endovascular (EVT) treating hospitals that have established transport services in place to transfer subjects to hospitals capable of performing EVT.

NCT ID: NCT03517709 Recruiting - Hypertension Clinical Trials

Feasibility of Home Telehealth Monitoring for Improvement in Management of Hypertension for Secondary Stroke Prevention

Start date: December 20, 2016
Phase: N/A
Study type: Interventional

This research is being done to determine how home blood pressure monitoring, using a commercially available blood pressure monitor with the capability of transmitting readings to stroke doctors can help manage blood pressure in the optimal range after a stroke. High blood pressure is the leading risk factor for stroke. It is important to control high blood pressure after a stroke to prevent another one from happening. We will use the Withings Smart Blood Pressure Monitor for daily blood pressure measurements. Tracking of blood pressure measurements will be done via iPod Touch equipped with internet connectivity. We hope to learn if this method of managing blood pressure is more effective than the standard way of having patients visit primary care physicians (the control group for this study). We will also get feedback from participants who will receive the Withings Smart Blood Pressure Monitor about the ease of use and overall satisfaction with this blood pressure device. People 18-100 years old who have had a stroke in the past 6 months may join. You will be excluded from the study if you are pregnant or plan on becoming pregnant in the near future.

NCT ID: NCT03517657 Recruiting - Stroke Clinical Trials

Bilateral Priming Plus Task Specific Training for Severe Upper Limb Hemiparesis

Start date: January 20, 2018
Phase: N/A
Study type: Interventional

The purpose of the study is to determine the best treatment for the arm that has been affected by a stroke. The investigators plan to determine if the arm affected by a stroke will improve with a combination of motor priming and motor training. Motor priming provides a warm up for the brain so that the brain and body will better respond to treatment. There are two types of priming in this study. One is called bilateral motor priming which involves using both hands. Bilateral priming requires that the individual make continuous wrist movements in a low-tech gadget called the Exsurgo primer, a piece of equipment in which each hand goes between two plates that are connected together so that the stronger wrist moves the weaker wrist in and out at the same time. The second type of priming includes use of low intensity stimulation for your affected arm. Understanding the benefits of priming will improve the efficacy of treatment for future patients with stroke. The investigators expect both groups to improve in arm function and impairment. The investigators expect the bilateral priming group will have more improvement. The study team anticipates enrolling approximately 76 individuals with stroke at Northwestern University and Shirley Ryan AbilityLab into this study. Each participant will have 24 visits. Nine visits will be for evaluation and fifteen for therapy. Each visit will be two to three hours depending on the type of visit and tests being done. Participants who are eligible and want to participate in this study will be randomized (selected by chance) to one of the two groups. The possible groups are: 1) bilateral priming plus motor training and 2) electrical stimulation priming and motor training. Participants are not blinded. Evaluation sessions consist of three separate days of testing and will occur at three time points: (1) before treatment starts; (2) after treatment is completed; and (3) 8 weeks later (follow-up evaluation: visits 22-24). There are three motor assessments. The main test, Fugl Meyer Test of Motor function (FMUE) is a common test for movement of the arm after a stroke. Participants will also be tested on the Chedoke Arm and Hand Activity Index (CAHAI) and the Action Research Arm Test (ARAT). Finally, the Neuro-QOL (short form) will be administered. There is also an evaluation of cortical excitability using TMS. After a stroke, there is often an imbalance of excitability between the affected and less affected parts of the brain. The imbalance will be measured using Transcranial Magnetic Stimulation (TMS), a technique used in neurorehabilitation research.TMS will not be used for treatment. There will also be a grip termination evaluation. This test will determine how long it takes to relax the affected hand after gripping an object.

NCT ID: NCT03515486 Recruiting - Stroke Clinical Trials

Cerebellar Stroke and Mood Disorders

Start date: January 16, 2017
Phase: N/A
Study type: Interventional

Post-stroke mood disorders (PSMD), including depression, anxiety and apathy, are observed in about 30 % of stroke patients at follow-up 3 or 4 months after stroke occurrence. They impair the functional outcome of the patients and their quality of life. Among the different brain structures involved in PSMD the role of the cerebellum has been under-evaluated while it is now well-known to be involved in mood regulation. The aim of this study will be to describe the characteristics of mood disorders following a first acute ischemic cerebellar stroke using face to face interviews and mobile technologies and investigate their pathophysiological mechanisms through advanced brain Magnetic resonance imaging (MRI) evaluation of cortico-cerebello-cortical morphological and functional connectivity.

NCT ID: NCT03514186 Recruiting - Stroke Clinical Trials

The Intensive Comprehensive Aphasia Program (ICAP)

Start date: July 15, 2015
Phase: N/A
Study type: Interventional

The purpose of this study is to conduct a randomized clinical trial that assesses the efficacy and cost-effectiveness of an Intensive Comprehensive Aphasia Program (ICAP), specifically focusing on the variable of intensity. Half of the participants will receive 60 hours of intensive treatment over three weeks, while the other half will receive the same amount and type of comprehensive treatment distributed over 15 weeks.

NCT ID: NCT03513315 Recruiting - Heat Clinical Trials

Heat Emergency Awareness and Treatment (HEAT)

Start date: November 30, 2016
Phase: N/A
Study type: Interventional

Investigators propose an intervention trial of a comprehensive education and treatment bundle designed to reduce morbidity and mortality associated with heat-related illness for low resource settings. Two set of interventions will be developed each for emergency department and for community/home. These interventions will be developed by an internal expert group and will be customized and implemented at the home and emergency department (ED) levels, will include evidence-based educational training guidelines for ED health providers as well as educational messages targeting home and community in Karachi, Pakistan.

NCT ID: NCT03511300 Not yet recruiting - Stroke, Ischemic Clinical Trials

Ready, Set, Goal: Motivation and Cognition in Stroke Patients

Start date: June 1, 2018
Phase: N/A
Study type: Interventional

Apathy is a syndrome of reduced motivation, characterized by diminished goal-directed behaviours (e.g., lack of effort), decreased goal-oriented cognitions (e.g., lack of interest) and blunted affect. Apathy is present in 20-50% of individuals after experiencing a stroke. Despite the detrimental impact of reduced goal-directed behaviours and cognitions on activities of daily living and cognition in stroke patients, interventions for increasing motivation (reducing apathy) have yet to be examined in this population. This study will examine the effect of goal-setting instructions on cognitive performance in stroke patients. The investigators hypothesize that in stroke patients, goal-setting instructions will improve cognitive performance relative to standard instructions. If goal-setting instructions are effective in improving cognitive performance, it may indicate that treatments targeting apathy could serve as a novel way to improve cognitive outcomes and enhance patient quality of life post-stroke.
