Filter by:Background: Cerebrovascular accident [CVA or commonly known as stroke] and traumatic brain injury (TBI) are common causes of morbidity, and motor impairments. Many stroke and TBI patients encounter severe functional impairments of their arm and/or hand. Recent studies have indicated that robotic training can improve upper limb function by enabling repetitive, adaptive, and intensive training. One type of robotic training is error enhancement during three-dimensional movements. The goal of this approach is to elicit better accuracy, stability, fluidity and range of motion during reaching. Previous research indicated the potential of robotic training with error enhancement as a viable clinical intervention for individuals facing motor deficits. Objectives: To evaluate the safety and efficacy of a new robotic system based on error enhancement and intended for rehabilitation of motor hand functions of post-stroke and TBI patients. Methods: A randomized, multi-center study with an open-label design. The study sample will consist of 96 participants who will be randomized into 2 separate groups. The intervention group consisting of 48 patients will receive training with the new robotic system, while the control group consisting of additional 48 patients will receive only standard practice treatments (with no exposure to the new robotic system). The outcomes of safety (adverse events and treatment tolerability), and efficacy (motor function, speed, tone, and spasticity) will be assessed and compared between the two groups. The assessment of the outcomes will be conducted at four different time points: (1) prior to the initiation of the four-week intervention, (2) after 2 weeks of intervention, (3) at the conclusion of the intervention, and (4) at a three-month follow-up session.
The etiology and specific pathogenesis of many cardiovascular diseases such as coronary atherosclerosis, cardiomyopathy, atrial fibrillation, and stroke are still unclear. Improving diagnosis and treatment, clarifying the pathogenesis, and providing scientific basis for the prevention and treatment are hot research topics in the study of cardiovascular and cerebrovascular diseases. This study intends to collect clinical data and biological specimen data of patients with cardiovascular and cerebrovascular diseases who meet the inclusion and exclusion criteria, and use multi-omics technology to deeply understand the pathogenic mechanisms of cardiovascular and cerebrovascular diseases and provide new ideas for specific and individualized treatment of patients with cardiovascular and cerebrovascular diseases, to construct early predictive prognostic models and provide a basis for effective treatment of clinical practice in patients with cardiovascular and cerebrovascular diseases.
Antiphospholipid syndrome (APS) has a close association with ischemic stroke; however, the optimal treatment strategy for APS-related stroke has yet to be established. The clinical guidelines suggest using warfarin for APS-related stroke, but these suggestions are largely based on retrospective studies from the 1990s and expert opinion, rather than high-quality clinical trials. Moreover, the evidence on the role of antiplatelet drugs other than aspirin (e.g., clopidogrel) in APS-related stroke is particularly limited. Considering the relatively young age of patients with APS and the high clinical burden of using warfarin, it is necessary to verify whether warfarin is essential. Thus, the investigators aim to compare clopidogrel-based antiplatelet therapy and warfarin as a secondary preventive medication for patients with APS-related stroke. APS-STROKE is an exploratory, multicenter, prospective, randomized, open, blinded-endpoint clinical trial. Adult patients with definite APS who have a history of ischemic stroke will be included. Patients with high-risk APS (triple positivity or persistently high titers of anti-cardiolipin or anti-β2-glycoprotein I antibodies), systemic lupus erythematous, or indications for continued antiplatelet or anticoagulant therapy will be excluded. Eligible patients will be 1:1 randomized to receive clopidogrel-based antiplatelet therapy or warfarin. Patients assigned to the clopidogrel-based antiplatelet therapy group will be permitted to use additional antiplatelet drugs other than clopidogrel at the investigator's discretion. The primary outcome is a composite of any death, major adverse cardiovascular events, systemic thromboembolic events, and major bleeding during a follow-up period of at least 2 years. This study would provide valuable information for determining the optimal secondary prevention strategy for APS-related stroke.
The purpose of this study is to evaluate the effectiveness of social network in improving drug compliance and risk factors control rate of stroke high-risk population after discharge.
30 participants (15 males and 15 females) who are ≥18 - ≤ 40 years old and considered healthy will be enrolled into this study to test the role of reactive oxygen species (ROS) in regulating cerebral blood flow (CBF). Participants can expect to be on study for 2 study visits over a 6 month period.
The primary aim of the study is to develop a national registry of cerebrovascular diseases in order to define the subtypes of these diseases associated with a worse prognosis. Secondly, the study aims to find clinical, radiological, and biological markers capable tof predicting the outcome of cerebrovascular diseases and the onset of complications related to therapeutic procedures, and to calculate predictive prognostic scores composed of multiple variables. Each participating center will collect clinical, radiological, and biological data from the medical records of the study participants. Patients included in the study will not undergo any additional medical procedures to those of normal clinical practice.
This study aims to establish a multicenter, large-scale, prospective cohort of patients with ischemic stroke. Various biological samples such as blood, feces, and urine are collected to identify biomarkers associated with ischemic stroke. By integrating demographic information, clinical indicators, imaging parameters, and biomarker parameters, the study aims to develop risk assessment, early warning, and prognosis prediction models. Additionally, the study aims to identify key genes and explore relevant signaling pathways related to ischemic stroke.
The management of small unruptured intracranial aneurysms (UIA) with ischemic cerebrovascular disease (ICVD) has been a very controversial topic in neurosurgery. Thus, we initiated a multicenter, prospective, randomized controlled trial (PROBE) design to elucidate in UIA patients with ICVD who do not qualify for preventive endovascular or neurosurgical intervention whether aspirin treatment decreases the risk of aneurysm growth and rupture.
The specific study aims will be: 1. To design and develop the hardware and software of the VR+MT and MR+MT systems. 2. To test the feasibility of the VR+MT and MR+MT systems from the patients and to collect the feedback of users with respect to their experiences. 3. To examine the treatment effects of VR+MT and MR+MT compared to the traditional MT (i.e., control group) in patients with stroke by conducting a randomized controlled trial. 4. To identify who will be the possible good responders to VR+MT and MR+MT based on their baseline motor functions and mental imagery abilities.
