Filter by:This is an observational prospective study about the reperfusion rate of intravenous thrombolysis on ischemic stroke patients with large vessel occlusions and predictor factors of successful recanalization.
This is a phase III trial trying to determine whether 12-hour bed rest following thrombectomy for ischemic stroke is non-inferior to 24-hour bed rest by measure of outcomes on the modified Rankin Scale (mRS) at 90 days post bed rest.
This is a phase III trial trying to determine whether 12-hour bed rest following IV thrombolysis therapy (i.e. tPA) for ischemic stroke is non-inferior to 24-hour bed rest by measure of outcomes on the modified Rankin Scale (mRS) at 90 days post bed rest.
The main purpose of this trial is to determine whether Xingnaojing, intravenously administered within 24 hours of symptom onset, improves the daily living ability of acute ischemic stroke at 90 days.
Stroke is one of the leading causes of death and long-term disability. A major unresolved problem in MRI-based stroke assessment is to relate image features to brain function in a way that can properly guide stratification for treatment and rehabilitation. This requires extracting meaningful and reproducible models of brain function from stroke images, a daunting task severely hindered by the great variability of lesion frequency and pattern. Large datasets are imperative to uncover possible lesion-function relationships. In this project the investigators will create a large database of acute strokes MRIs. The investigators will retrospectively archive an estimated 3,000 MRIs of patients with acute stroke, acquired at the Johns Hopkins Hospital, 2009-2019. This dataset will include 1.5 and 3 Tesla scans, diverse protocols and sequences (e.g., diffusion and perfusion weighted images (DWI/b0, PWI), T1, T2, FLAIR, susceptibility weighted images), with typical clinical low voxel resolution (4-7 mm3). Lesions will be initially delineated on DWI/b0, the most informative MRI sequence for acute stroke. After anonymization and defacing, two trained evaluators will perform the manual lesion segmentation. Two expert neuroradiologists will create consensual structured radiological reports with information about stroke type and location according to different criteria (e.g., 34 brain structures and 11 vascular territories). The investigators will also archive structured information from discharge (demographics, laboratory, and neurological evaluation of patients, including NIH stroke scale and modified Rankin scale, mRS), as well as the 90-days follow-up mRS.
This is Versi Retriever mechanical thrombectomy device approving study in Japan. Multi center, single arm, prospective registry trial. Physicians control trial, conducted my N Sakai, Kobe City Medical Center General Hospital.
Study objective is to determine whether Pioglitazone (PGZ) can improve clinical outcomes in hyperglycemic acute ischemic stroke (IS). The rationale for the proposed research is to develop an acute intervention that can improve neurological recovery and decrease mortality and morbidity in high-risk diabetic stroke patients.
This study attempts to minimize the development of a common movement impairment following stroke known as "flexion synergy" that makes it extremely difficult to reach outward with the arm. Participants with acute/subacute stroke will receive one of two study interventions in addition to prescribed therapies in both inpatient rehabilitation and day-rehab. Participants will be followed for 1 year.
The purpose of this study is to establish a methodological framework based on existing advanced neuroimaging technologies as a new clinical neuroimaging tool for assessment of possible affected brain connections in stroke and TIA patients. Thus, providing new insights into microstructural changes that may underline why those patients experience deficits like fatigue.
Severe stroke remains an important cause of mortality and morbidity, despite advances in disease management, acute treatment and secondary measures. Among all post-stroke complications, pneumonia constitutes a major complication with a strong impact on morbidity and mortality. Research also showed that a reduction in respiratory muscle and abdominal muscle strength contributed to pulmonary and respiratory dysfunction following a stroke. Low respiratory muscle function decreases the efficacy of rehabilitation because it leads to exercise intolerance in stroke patients. Thus, special exercise programs are needed to improve the pulmonary function and respiratory muscle strength of stroke patients The aim of pulmonary rehabilitation program is to enhance respiratory muscle resistance during breathing, thereby improving respiratory function. Previous studies demonstrated that pulmonary rehabilitation programs improved respiratory functions in cardiac disease and chronic obstructive pulmonary disease patients
