N20 somatosensory evoked potential (SEP) response shows high predictive accuracy of functional recovery in patients with acute ischemic stroke (AIS) undergoing endovascular thrombectomy (EVT). This capacity is independent and even higher than clinical and advanced imaging variables. This study aims to validate BraiN20®, a portable, non-invasive, automatic device to monitor in real-time the presence and characteristics of N20 in AIS patients. 65 patients with AIS and anterior LVO undergoing EVT within 24 hours from onset will be included in three comprehensive stroke centers of Catalonia, Spain. Eligibility criteria are no significant pre-stroke functional dependence, baseline National of Institute of Health Stroke Scale (NIHSS) score equal or higher than 6 points, occlusion (modified Thrombolysis in Cerebral Infarction, (mTICI) 0-1) of the intracranial internal carotid artery (ICA), middle cerebral artery (MCA)-M1 or M2 suitable for EVT per local protocols, without infarct volume restrictions measured by Alberta Stroke Program Early CT (ASPECT) score or by Perfusion Computed Tomography (PCT)/Diffusion Weighted Imaging-Magnetic Resonance Imaging(DWI-MRI) prior to EVT . The primary objective is to confirm an optimal/good reliability of N20 registration before EVT higher than 75% by two blind expert neurophysiologists, assuming a true proportion equal to 87.5%. Secondary endpoints are the predictive accuracy of N20 response recorded by BraiN20® before and after EVT on functional outcome evaluated by the mRS at 7 and 90 days and analyzed by using Receiving Operating Characteristic curves (ROC). A futility interim analysis is planned after the inclusion of 25% population. The trial is sponsored by Time is Brain S.L. and started in September 2023. Primary endpoint results are expected for the first quarter of 2024. BraiN20® could be a useful medical device to predict salvageable brain and functional recovery of patients along the stroke chain.
In the acute posterior circulation strokes, the vertebrobasilar occlusions frequently related to worse outcomes than the anterior ones. However, few studies mentioned the benefit and safety of the emergent stenting in the successful recanalization at these complex occlusions. The investigators investigated whether the improvement of clinical outcome was achieved in postprocedural 3-month.
The successful recanalization is the essential standard for the tandem lesions in acute anterior ischemic stroke. However, one of the common complications after emergent carotid stenting is hemorrhagic transformation that makes the effect of this method controversial. The investigators investigated whether emergent carotid stenting achieved the improvement of clinical outcome in acute large vessel occlusion stroke.

Cerebrovascular accident(CVA) or stroke is one of common condition affecting people in developed and underdeveloped countries. MRP is a therapy to regain particular motor function and neglecting accessory movements by engaging cognitive behavior. Mirror therapy enhance functional activities in patient with hemiplegic stroke. For betterment of result high quality methodological studies and larger sample size is required.
The purpose of this pilot study is to explore the impact that a structured anxiety reduction intervention program has on patients being discharged to home following an acute stroke in an academic medical center. Eligible participants will be screened and recruited by the research team through daily rounds. After completing the informed consent process, the research team will pull demographic information from the electronic health record (EHR) and REDCAP that includes ethnicity and support system. Participants will complete the Anxiety Screen Questionnaire (GAD-7 ANXIETY SURVEY) and will be provided with information regarding stroke support groups available with additional NYU Langone Health and the American Heart Association internet-based information regarding anxiety reduction (NYU Langone Health Anxiety Reduction Bundle). The participants will be encouraged to attend a stroke support group for 3 months and utilize the NYU Langone Health Anxiety Reduction Bundle provided. At the completion of the intervention (3 months), participants will be provided with the GAD-7 ANXIETY SURVEY again and a survey that includes open-ended questions and a program evaluation by email. Analysis will occur after final data is collected.
The aim of this study was to evaluate the effect of early administration of sour liquid on swallowing function of patients with post-stroke dysphagia. Hypothesis of the study were; H0: The sour liquid given early to patients with post-stroke dysphagia does not have an effect on swallowing function H1: The sour liquid given early to patients with post-stroke dysphagia has an effect on swallowing function The data of the study were collected using the "Personal Information Form," "Standard Swallowing Test," "Gagging Swallowing Screening Test (GUSS)," and the " National Institute of Health Stroke Scale (NIHSS)". Early administration of sour liquid to patients with post-stroke dysphagia was found to have a positive effect on swallowing function.
Post stroke pneumonia (PSP) is one of the common early complications of stroke. Post-stroke infections, in general, are associated with less favorable neurologic outcomes. Aspiration is one of the most feared complications of enteral nutrition and can lead to the occurrence of pneumonia. Severe stroke patients are at high risk for aspiration due to some factors such as the reduced level of consciousness, inability to protect the airway and so on. The purpose of this study is to explore the ideal nutrition support strategy for patient with acute severe stroke to help reduce the incidence of PSP and improve the prognosis.
Stroke is the leading cause of adult-onset disability, and affects 15,000 Veterans each year. Successful rehabilitation and recovery following a stroke requires therapy including repetitive task training. However, repetitive task training can be draining for both the clinician and the patient as it requires the participant to complete many repetitions of the same task and those repetitions can be difficult to accomplish with appropriate technique. Robot-mediated repetitive task training has the potential to facilitate the clinical delivery of proven rehabilitation programs to Veterans in need and recently a new exoskeleton has been developed, called Harmony, which can deliver bimanual 3D arm therapy. The investigators propose to develop and test two novel controllers', synergy avoidance and task assistance, that use promising neurological basis for training to facilitate repetitive task training while ensuring correct movement patterns in acute and sub-acute stage stroke patients. This has the potential to improve Veterans' activities of daily living and quality of life.
Investigation on changes in the neurochemical stress parameters in acute stroke. 30 patients are recruited in the stroke unit, blood samples are collected at fixed intervals during the first two days. Patients are randomized to music listening and control.Neuropsychological testing is performed in the acute phase and 6 months post-stroke.
