Filter by:Our primary aim is to investigate whether remote ischemic conditioning (RIC) as an adjunctive treatment can improve long-term recovery in acute stroke patients as an adjunct to standard treatment.
This study is a randomized, double-blind, placebo-controlled, multicentre, Phase 2 study, with an optional open-label extension, to evaluate the safety, tolerability, and efficacy of RPh201 in subjects with mild to moderate AD who are eligible for enrollment in this study. Subject participation will include a Screening Phase, Treatment Phase, and an Optional Open-Label Extension. The Screening Phase will be up to 4 weeks prior to randomization. Both the subject and their study partner(s) will sign an informed consent form (ICF). At Visit 2, Subjects will be randomized 2:1 to RPh201 or placebo. The Treatment Phase will last for 6 months post-randomization, or until subject withdrawal from the study, whichever comes first. The Optional Open-Label Extension will begin once a subject has completed the Treatment Phase and the subject and their study partner(s) have signed an ICF to continue on the study. The Optional Open-Label Extension will continue for 6 months, or until subject withdrawal from the study, whichever comes first. Subjects who do not participate in the Optional Open-Label Extension will be asked to return for an optional post-study visit 6 months after the end of the Treatment Phase. Subjects may participate in an optional biomarker sub-study. Up to 15 subjects may also participate in an optional FDG-PET sub-study during their study participation. Separate informed consent will be required for both of these sub-studies.
The aim of the current protocol is to study 40 patients, each for 12 weeks, to address hypotheses related to the ability of a telerehabilitation system to (a) improve motor status and disability, (b) collect various forms of patient data from the home, (c) improve risk factor knowledge and control, and (d) assess patient compliance with home-based telerehabilitation. Patients who have returned to their home after stroke will be provided with a telehealth system and be asked to use it 6 days/week for 12 weeks, during which time subjects will use this system for daily rehabilitation therapy, assessments, and education--all on one platform.
The FLOW trial is a randomized placebo-controlled trial analyzing the effect of coupling an anti-depressant, fluoxetine (Prozac), and exercise to improve motor recovery following a stroke.
Gait recovery is one of the main goals of post-stroke rehabilitation where robotic-assisted practice has shown positive outcomes. However, literature lacks of clinical studies on exoskeleton-supported gait rehabilitation. Recently, a wearable exoskeleton (Ekso™, EksoBionics, USA) has been commercialized for re-enabling patients to stand and walk, involving them directly in steps trigger through body weight balance. The main aim of this study is to assess the clinical and neuromuscular effects of exoskeleton-based gait rehabilitation in sub-acute and chronic stroke patients, compared to patients with similar characteristics who will conduct a traditional over-ground gait training. In this multicentric RCT, 162 stroke patients will be enrolled and randomly assigned to the Experimental Group (EG) or to the Control Group (CG). Patients will conduct at least 12 one-hour-sessions (about 3 times/ week) of Ekso™ (EG) or traditional over-ground (CG) gait rehabilitation. Clinical evaluations (lower limb Modified Ashworth Scale- MAS; Motricity Index - MI; Trunk Control Test - TCT; Functional Ambulation Classification - FAC; 10-meter walking test - 10mwt; 6-minute walking test - 6mwt; Walking Handicap Scale - WHS; Time Up and Go - TUG) will be administered to patients at the beginning (T1) and at the end (T2) of the training period. The primary outcome is the distance performed during the 6mwt. A follow up study at 1 month (T3) and at 3 months (T4) after T2 will be conducted.
Background: A stroke occurs when not enough blood reaches the brain. Sometimes stroke causes changes in certain brain matter. This is called white matter hyperintensity (WMH) and can lead to mental decline. But not all WMH is caused by stroke. Not all people with WMH experience mental decline. Researchers want to learn more about WMH. They want to see if it is related to disruptions in the blood-brain barrier. Objective: To better understand the how blood-brain barrier disruption is related to white matter hyperintensities. Eligibility: Adults at least 18 years old who have been admitted to a study site with stroke-like symptoms Design: Participants will be screened with an MRI scan and cognitive tests. Participants will have 11 visits over 6 years. Each visit will be 3-4 hours. At each visit, participants will: Update their medical history Have a thin plastic tube (catheter) inserted into an arm vein by needle Have an MRI. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. Participants will be in the scanner about 60 minutes, lying still for up to 20 minutes at a time. They will get earmuffs for loud sounds. Have a dye injected through the catheter during the MRI Have tests of movement, language, and cognition Some participants will have an extra visit for an MRI in a stronger scanner (7T MRI). Participation for some participants will be authorized by their legal representative.
To study, prospectively, the association between dietary patterns and risk of health outcomes (cardiovascular, metabolic, endocrine, neurological, skeletal muscular, cancer) in cohort study of 116,671 women age 24 to 44 years at baseline in 1989 (the Nurses' Health Study II; NHS II).
This is a single institutional registry database for the patients with stroke and cerebrovascular diseases. Stroke is the fifth leading cause of death in the United States. Despite extensive research, most of the patients die or suffer from varying degree of post-stroke disabilities due to neurologic deficits. This registry aims to understand the disease and examine the disease dynamics in the local community.
This study compares the accuracy of fusion imaging (Fusion Roadmap) versus real-time X-ray imaging (Roadmap) during catheterization of supra-aortic trunks of in patients with aneurysms or arteriovenous malformations.
This trial will evaluate a non-invasive brain imaging technique QUTE-CE MRI and validate the method with first-in-human studies.
