NCT ID: NCT03298243 Not yet recruiting - Stroke Clinical Trials

Use of Sensory Substitution to Improve Arm Control After Stroke

Start date: September 2017
Phase: N/A
Study type: Interventional

Supplementing or augmenting sensory information to those who have lost proprioception after stroke could help improve functional control of the arm. Twenty-eight subjects will be recruited to a single site to evaluate the ability of various forms of vibrotactile stimulation to improve motor function, and to determine which locations of stimulation may optimize function. Participants will be tested in performing reaching movements and stabilization movements as well as more functional tasks such as simulated drinking from a glass

NCT ID: NCT03297827 Recruiting - Ischemic Stroke Clinical Trials

Cytokine Registry Database of Stroke Patients

Start date: October 5, 2017
Phase: N/A
Study type: Observational [Patient Registry]

Various molecules (cytokines: interleukins, interferons and neural proteins) found in human and animal blood are reported to be elevated in acute stroke (Ischemic and hemorrhagic). Cytokines can be pro-inflammatory or anti-inflammatory. There are studies confirming level changes in serum of humans in the setting of several rheumatologic and cardiovascular diseases. As new molecular markers (cytokines and neural tissue markers) are established in scientific literature, stroke scientists are interested to evaluate the role of these in the pathophysiology of stroke. Investigators intend to study the role of these molecules in the development of stroke. Acute stroke treatment has advanced considerably in the last 10 years with the establishment of comprehensive stroke centers and approval of neuro-interventional techniques. However, the molecular advancement in stroke pathogenesis has yet to reach a milestone in the world of stroke treatment. In our opinion, creating a database of acute stroke patients containing all pertinent medical demographics and clinical information along with the laboratory data, molecular levels of pertinent cytokines/neural factors from consenting patients, will help us define and delineate the most relevant molecules that are altered in acute stroke patients and can help us further improve us understanding of the role of these in acute stroke and thereby hopefully help in the improvement of our understanding and management of stroke. Moreover, analyzing the cytokines in stroke and ICH patients would help understand their role in the acute phase, which may become potential therapeutic adjuncts for tPA and endovascular thrombectomy.

NCT ID: NCT03296852 Recruiting - Stroke, Acute Clinical Trials

Study: SONAS Ultrasound for Detecting Stroke SONAS Ultrasound for Detecting Stroke

Start date: October 20, 2017
Phase: Early Phase 1
Study type: Interventional

The purpose of this research study is to test a new medical device, called SONAS. The SONAS device is a portable, battery-powered ultrasound device to detect strokes in the prehospital environment, such as emergency vehicles (eg. ambulances, helicopters). To demonstrate the safety of the device the goal is test it in a small number of healthy volunteers first. The SONAS device will be used to detect changes in blood flow to the brain through ultrasound, otherwise known as TransCranial Doppler (TCD). To date, the SONAS device has been tested extensively in the laboratory, in animals and in human cadavers. The purpose of the present study is to test the device for safety and efficacy in a small group of healthy volunteers. This study will test the device on 10 healthy volunteers. Each volunteer will have a physical examination, neurological examination, and brain MRI both before and after the TCD test is performed. All of these study procedures will be performed on 1 visit, lasting approximately 5 hours. The brain MRI's will be used to verify the effectiveness of the SONAS device on detecting changes in blood flow to the brain.

Intracerebral Transplantation of Neural Stem Cells for the Treatment of Ischemic Stroke

Start date: June 2012
Phase: Phase 1
Study type: Interventional

The study is to determine the safety of human neural stem cell transplantation for the treatment of paralysis and related symptoms due to chronic motor stroke and to determine the maximum tolerated dose.

NCT ID: NCT03295032 Completed - Stroke Clinical Trials

A Mixed-methods Evaluation of an Adapted Acceptance and Commitment Therapy (ACT) Group for Stroke Survivors

Start date: March 1, 2016
Phase: N/A
Study type: Interventional

Stroke is one of the main causes of acquired adult disability in the UK. Many psychological problems can also occur post-stroke; this has a marked impact on health service usage. As such, there is an outstanding need to increase and improve psychological resources within stroke services. The investigators proposed to adapt and evaluate the effectiveness of an acceptance and commitment therapy (ACT) group intervention for adult stroke survivors and their carers. The group will endeavour to promote positive adjustment and reduce levels of depression and anxiety. This study will have two parts.

NCT ID: NCT03294187 Not yet recruiting - Stroke Clinical Trials

Encouragement-induced Movement Therapy in Daily Life

Start date: September 25, 2017
Phase: Phase 2
Study type: Interventional

Stroke places a major burden on health care and society. It often leads to a hemiparesis. Intensive stroke rehabilitation speeds up recovery. In daily practice, the financial and/or human resources to provide this intensive rehabilitation are often lacking. Applying modern-day tracking and feedback technology to encourage a self-administered, context specific training is expected to offer significant potential to increase intensity of practice. Up until now, there has been no randomized trial examining the effect of such an intervention on daily arm usage. The primary objective of this study is to determine the effect of wearing an activity tracking and multimodal feedback device for six weeks on self-reported daily life use of the paretic arm after stroke, when compared to control group stroke subjects wearing a hardware-wise identical sham device providing no feedback. The secondary aim is to examine compliance to use the device and the quantitative, qualitative and functional improvement of the paretic arm. It is hypothesized that participants in the experimental group show a higher change in self-reported daily life use of the paretic arm when compared to the control group both post intervention and at 6-week follow-up. ISEAR is a multicenter, assessor-blinded randomized controlled trial of 62 subjects beyond the first 3 months poststroke.

NCT ID: NCT03292575 Recruiting - Stroke Clinical Trials

Study of the Follow-up of Stroke Treated With Anticoagulants

Start date: January 2016
Phase: N/A
Study type: Observational

Stroke is a major public health problem as it is very frequent (140,000 cases/year in France), and very serious (leading cause of death, 2nd leading cause of dementia, 3rd leading cause of handicap). Ischemic cardio-embolic stroke accounts for around 25% of ischemic strokes, and ischemic cardio-embolic stroke in a context of cardiac arrhythmia due to atrial fibrillation (CAAF) is the leading non-atheromatous cause. The aim of this study is to optimise the secondary prevention of CAAF-related stroke identified at the University Hospital of Dijon Burgundy in the framework of the recommendations of the '2010-2014 stroke plan' and the Compulsory Consultation at the 6th month (Directive DGOS//2015/262 of the 3rd August 2015)

NCT ID: NCT03292211 Enrolling by invitation - Hemorrhagic Stroke Clinical Trials

The Effect of Early Mobilization in Mild to Moderate Hemorrhagic Stroke

Start date: September 12, 2017
Phase: N/A
Study type: Interventional

This study aims to examine the outcomes of early mobilization and early intervention within 3 days after the onset of hemorrhagic stroke in patients admitted to an intensive care unit within 48 hours after stroke. The patients after hemorrhagic stroke who undergo early intervention only will be compared with those who also receive early mobilization in order to determine if the early mobilization intervention results in earlier or more effective recovery of postural stability, activities of daily living function, or motor capacity. The participants will be randomly assigned to the following two groups: (1) the early mobilization (+early rehabilitation) group and (2) the early rehabilitation group.The measurement parameters will be collected before the intervention (basic parameters), two weeks after the stroke, four weeks after the stroke and three months after the stroke. SPSS (version 17.0) will be used to carry out repeated measures analysis of variance (repeated ANOVA) to compare the differences between the groups at different time points (including basic values and follow-up values). For statistical significance, Bonferroni correction will be applied for the post-hoc analysis of the groups.

NCT ID: NCT03292159 Not yet recruiting - Stroke Clinical Trials

Transcutaneous Vagus Nerve Stimulation for Motor Recovery After Stroke

Start date: January 2018
Phase: Phase 1/Phase 2
Study type: Interventional

This study will evaluate the safety and effectiveness of Respiratory-gated Auricular Vagal Afferent Nerve Stimulation (RAVANS) for improving motor recovery after stroke. Subacute stroke patients will receive RAVANS or sham stimulation concurrent with arm motor training during 10 intervention sessions occurring daily for 30 minutes over 2 weeks. The safety and improvements in arm motor function after the intervention will be compared in patients receiving RAVANS to those receiving sham stimulation.
