Filter by:Brain activation can be studied using the Functional Near InfraRed Spectroscopy (fNIRS). It was shown that CPF activation during walking and during dual task could be different in stroke patients and in healthy subjects. To date, fNIRS reliability is not completely established during walking and during dual task. Therefore, this study will examine the reproducibility of fNIRS parameters during simple walking and during dual task in healthy subjects and in stroke patients.
Prospective multicenter study of consecutive patients with acute ischemic stroke and large intracranial vessel occlusion in which a thorough and systematic evaluation of all variables that may be related to the degree of collateral circulation is performed.
Study Objective is to establish the feasibility and safety of the NOVIS Transcarotid Neuroprotection System when used for the transcarotid intervention of patients that have a failed transfemoral endovascular therapy in the case of anterior circulation strokes due to large vessel embolic occlusions.
The development of intravenous thrombolysis has greatly improved the rate of recanalization and reperfusion in patients with acute ischemic stroke, increasing the proportion of patients with good outcome and reduced mortality. The guideline recommends that patients with ischemic stroke should be treated with intravenous thrombolysis within 4.5 hours. The latest meta-analysis found that ischemic stroke with onset time of 4.5-9 hours with infarction core volume <70ml, ischemic penumbra volume >10ml, and hypoperfusion volume / infarction core volume >1.2 could be benefit from intravenous thrombolysis. The DAWN clinical trial has shown that patients with ischemic stroke with large vessel occlusion with onset time of 6-24 hours could be benefit from endovascular treatment after screening by multi-mode imaging. Therefore, we hypothesize that patients with ischemic stroke with onset time of 4.5-24 hours with a definite penumbra may also benefit from intravenous thrombolysis. The purpose of this study is to explore whether the patients with ischemic stroke with onset time of 4.5-24 hours can benefit from intravenous thrombolysis if they meet the standard of CT perfusion screening.
This research aims to understand the efficacy of a visual training task to improve visual loss after stroke, also known as hemianopia. The investigators aim to understand whether training can improve vision and which areas or pathways in the brain are responsible for this improvement.
The objective of this study is to establish a near-real-time prospective monitoring program in Medicare, Optum and MarketScan Research data to evaluate the benefit of new cardiovascular disease (CVD) drugs for older adults with frailty. Prospective monitoring program seeks to find early effectiveness and safety signals of new drugs by updating the analysis at regular intervals as new Medicare data become available. This study specifically aims to emulate a prospective surveillance of the effectiveness and safety of non-vitamin K oral anticoagulants (NOAC) vs. a comparator, warfarin, in older adults with atrial fibrillation and different frailty status. This program will be enhanced by incorporating a novel claims-based frailty index, which has been shown useful in assessing how the benefits and harms of drug therapy vary by frailty.
Stroke is a leading cause of disability in the U.S. and many Veteran stroke survivors live with severe disability. Despite recent advances in rehabilitation treatments many stroke survivors have persistent physical and mental difficulties such as reduced physical and cognitive function and depression. Developing innovative treatments that address these problems is necessary to improve long-term outcomes for stroke survivors. Aerobic exercise (AEx) can improve physical and cognitive function, and reduce depression. Additionally, AEx may enhance physical rehabilitation by making the brain more receptive to, and consequently improving the response to an intervention. Therefore, combining AEx with physical rehabilitation has the potential to improve multiple aspects of stroke recovery. This study will examine the effect of combining AEx with physical rehabilitation on physical and mental function in stroke survivors. By gaining a better understanding of the effects of this combined intervention the investigators aim to advance the rehabilitative care of Veteran stroke survivors.
The focus of this study is to optimize the delivery of a combined strength and aerobic training regimen to individuals with post stroke hemiparesis and reduce overuse and inefficiencies associated with the nonparetic leg during walking. This study proposes to use 1) split-belt treadmill and 2) single belt treadmill walking using split belt simulation software for enhancing symmetrical walking patterns for people with stroke.
Telemedicine is an incipient resource to support the stroke system of care in Colombia. Several studies had demonstrated that patients benefit by implementing telestroke, for instance, providing timely and appropriate neurological consultation, diminishing accessible barriers, improving medication adherence for secondary prevention and facilitating linkages between patient and physician, especially for those in rural or neurologically underserved areas. Hypothesis: The use of Telemedicine improves medication adherence in Post-ischemic Stroke. Study Design: This is a randomized, single-blind, clinical trial to assess the efficacy of Telemedicine, over medication adherence in Post-ischemic Stroke subjects from Colombia. Population: Eighty-four Post-ischemic Stroke subjects, subjects of both genders, over 18 years old, with a first stroke will be included. Ethical Aspects: The study will be conducted according to the Helsinki declaration, the good clinical practices guidelines and the Colombian legislation. Prior to entering the study, patients must sign a written or oral informed consent that has been approved by the Institutional Ethics Committee of Fundación Cardiovascular de Colombia. Overall objective: this study aims to determine the efficacy of telemedicine on pharmacological adherence in post-ischemic Stroke Participants. Focus of study: Adherence to secondary stroke prevention medication.
The purpose of this pilot study is to determine whether two weeks of multi-channel FES along with task-specific training will improve UE function when compared to traditional rehabilitation or usual care. The secondary purpose of this study is to find whether two weeks of multi-channel FES along with task-specific training will improve shoulder range of motion, grip strength, and patient reported function when compared to traditional rehabilitation or usual care in patients with unilateral stroke resulting in hemiplegia.The following null hypotheses are established for this study: 1. There will be no difference in UE function when using multi-channel FES along with task-specific training compared to traditional rehabilitation or usual care in patients with first time stroke and hemiplegia during in patient stroke rehabilitation. 2. There will be no difference in shoulder range of motion and grip strength when using multi-channel FES along with task-specific training compared to traditional rehabilitation or usual care in patients with first time stroke and hemiplegia during in patient stroke rehabilitation. 3. There will be no difference in self-reported upper extremity function when using multi-channel FES along with task-specific training compared to traditional rehabilitation or usual care in patients with first time stroke and hemiplegia during in patient stroke rehabilitation.The research design for this experimental study will be a randomized controlled trial. The manipulated independent variable in this study will be 1) FES using Xcite with traditional therapy and 2) traditional therapy. The dependent variables in this study are the following: Upper extremity function measured by The Action Research Arm Test, The Box and Block Test, and The Nine-Hole Peg Test; Grip strength measured using a dynamometer; Range of motion at the shoulder measured using a standard goniometer; and Participants' perception of improvement in function measured by a modified Patient-Specific Functional Scale.
