Filter by:A prospective, multicenter, randomized controlled, non-inferiority study to investigate the effectiveness and safety of SINOMED SR for endovascular treatment of acute ischemic stroke
After stroke, blood vessels in the brain can become damaged, and the brain's ability to control blood flow can be impaired. The brain therefore may be less able to maintain a healthy level of blood flow during challenges such as changes in posture. Studies have shown that sitting upright early after stroke can cause brain blood flow to reduce. However, no studies have investigated how standing up affects blood flow to the brain. In this study, transcranial Doppler ultrasound will be used to assess how cerebral blood flow velocity changes when acute stroke patients stand up.
This is a pragmatic, multi-center, prospective, observational, non-interventional study and standing database of patients hospitalized for transient ischemic attack (TIA) or stroke in the 11 accredited adult neurology training institutions in the Philippines. Data will be collected from each patient while admitted in the hospital and until hospital discharge. Data collection for this study will span 3 years from study initiation, after which the utility of an extension or a re-implementation of the study will be assessed.
Stroke and its sequelae are a major indication for acupuncture. The specific aims of this study are to assess the feasibility of pragmatic clinical trial on acupuncture in primary care setting and evaluate the effectiveness and safety of acupuncture for stroke rehabilitation in Hong Kong.
Using EEG and metabolomics to evaluate the clinical efficacy of Xinglouchengqi decoction in improving nerve injury in the acute stage of stroke and the mechanism
The purpose of this study is to investigate the effects of transcranial magnetic stimulation (TMS) on motor cortex excitability in individuals who have suffered stroke and to study the influence of the phase of the oscillatory rhythm (mu frequency) on motor excitability in stroke individuals.
Hypotheses: 1. Subjects with mild post-stroke cognitive impairment (PSCI) are at risk of developing vascular dementia (VaD). Maraviroc treatment in patients suffering from mild PSCI will halt its progression and improve cognitive outcome by affecting synaptic plasticity. 2. CCR5 inhibition produces an anti-inflammatory and anti-atherogenic effect by lowering macrophage infiltration and adhesion molecules. Thus, PSCI patients treated with Maraviroc will present a better inflammatory profile and a deceleration of carotid atherosclerosis, vs. placebo. Objectives: To investigate the safety and efficacy of Maraviroc 150 mg and 600 mg per day vs. placebo in patients with recent subcortical stroke who experience mild PSCI on progression/improvement of clinical symptoms of post-stroke cognitive impairment, change in disease biomarkers and inflammatory profile. The study will include 150 participants aged 50-86 years treated with Maraviroc 150mg or 600mg per day compared to placebo for 12 months in 3 sites.
Preliminary data will be collected about which individuals with spatial neglect from right hemisphere stroke (aiming vs perceptual neglect) improve with Prism Adaptation Training and if there is a particular pattern of damage in the brain that predicts both the type of neglect experienced and whether neglect is improved following Prism Adaptation Training
Language and communication are essential for almost every aspect of human life, but for people who have aphasia, a language processing disorder that can occur after stroke or brain injury, even simple conversations can become a formidable challenge. Speech and language therapy can help people recover their language ability, but often requires months or even years of therapy before a person is able to overcome these challenges. This research will investigate non-invasive brain stimulation as a way to enhance the effects of speech and language therapy, which may ultimately lead to better and faster recovery from stroke and aphasia. The investigators hypothesize that participants with aphasia who receive speech and language therapy paired with active electrical brain stimulation will improve significantly more on a language comprehension task than those who receive speech and language therapy paired with sham stimulation.
INTRODUCTION: After stroke, perceptual impairments, such as negative body perception, contribute to social isolation and depression. In the subacute poststroke phase, art therapy is effective in improving depression, self-esteem, and community integration. Yet, no study has explored the effectiveness of art therapy at the chronic stage of a stroke; where motor recovery is slowed, and body image and self-esteem are deeply challenged. OBJECTIVES: Primary; to assess the feasibility of an art therapy program (ATP) in the chronic phase of stroke. Secondary; to explore the effects of ATP on perceptual impairment (body image/self-esteem), mood and community integration. METHOD: Nine adults (stroke ≥6 months) will participate in the ATP consisting of a thematic group visit to the Montreal Museum of Fine Arts followed by an art workshop, supervised by an art therapist (7 visits over 4 months). Feasibility will be evaluated by triangulating data from interviews and subject assessment questionnaires and by assessing retention and attendance. The effects of the ATP will be assessed by changes in perceptual and mood impairment questionnaires (Body Image States, Self-Esteem scales, Beck Depression Inventory-Short-Form) and community integration questionnaire (The Community Integration Questionnaire). EXPECTED RESULTS AND OUTCOMES: The project will confirm the feasibility of ATP to improve perceptual impairment and community integration post-stroke.
