Filter by:The main objective is to develop models for the cortical reorganization of motor areas and inter-hemispheric equilibrium in the early phase of post stroke recovery evaluated by the fNIRS technique from day 0 to day 60 (day 0 being the day of inclusion in the study) and to correlate the latter with the early phases of motor recovery over the same period, as measured by the test Fugl-Meyer.
One of the most powerful predictors of stroke is hypertension, with estimates of approximately 33% of adults in the United States experiencing this condition. Hypertension is significantly more prevalent in African Americans compared to European Americans. Importantly, hypertension is a modifiable stroke risk factor. This proposal will use a community-based participatory research approach to perform a randomized trial of a mobile phone text-messaging intervention to reduce high blood pressure in an urban African American community in Flint, Michigan.
Stroke is one of the most devastating disorder worldwide. Hypertension has been confirmed to be a major modifiable risk factor for stroke.Even the casual visit hypertension has been managed ideally,there is still surplus risk for stroke re-attack.The purpose of this study is to explore whether variation of 24-hour ambulatory and visit-to-visit blood pressure variability (BPV) contribute to recurrent stroke.
The main objective of this study is to compare two post-stroke/TIA (transient ischemic attack) imaging strategies in terms of the number of clinically important (i.e. requiring specific treatment according to current recommendations) lesions detected. The first strategy is the current/usual strategy in each participating centre and the second strategy consists in starting the post-stroke/TIA imaging assessment by a whole-body, low-dose angiography and subsequently resorting to elements of the usual strategy if required.
The purpose of this study is to design a predictive model of stroke recovery based on baseline measurements of arm movement and brain physiology. The expectation is the development of a formula to predict a person's response to an arm rehabilitation program provided in the chronic phase (6 months or greater post stroke) of recovery. The study will include magnetic resonance imaging (MRI), transcranial magnetic stimulation (TMS), genetic testing using blood and saliva, and an arm exercise program consisting of robot-assisted exercise combined with functional arm exercise called transition to task training (TTT).
Cerebrovascular disease is a major cause of disability worldwide. The catastrophic burden of stroke is more dramatic in low- and middle- income countries, and the scarcity of evidence-based rehabilitation interventions represents a major challenge to global health care. Upper limb weakness is frequent after stroke, but there is no universally accepted treatment to effectively improve hand function in patients with moderate and severe motor impairment. These are the patients in deepest need of rehabilitative interventions. This project addresses this important issue, by testing effects of a novel approach. The investigators will non-invasively stimulate peripheral nerves in order to enhance effects of motor training aided by an electrical stimulation device in patients with moderate to severe hand weakness. Our hypothesis is that peripheral nerve stimulation will enhance effects of motor training in patients in the chronic stage after stroke.
The central questions of the study can be summarized as follows: What stroke / death rates are the result of the use of the following treatment strategies: no anticoagulation with vitamin-k-antagonists (VKAs) or novel oral anticoagulants (NOACs), anticoagulation with VKAs and anticoagulation with NOACs (all). What other thromboembolic complication rates resulting from the use of these treatment strategies? What heavy bleeding rates resulting from the defined management strategies? The analysis is based on a data set of patients with atrial fibrillation (AF)(01/01/2010 - 30/06/2014). 2010 is used as the reference period and 01/01/2011-30/06/2013 as the inclusion period. The minimum observation time per patient is 12 months. Used is a data base of the AOK PLUS as well as the AOK Baden-Württemberg and AOK Bayern. The aim of the study is to compare clinical outcomes between the different treatment strategies (frequency of events and time to first event). The influence of alternative treatment strategies is measured on the basis of three different methodological approaches: unadjusted comparison of event council and time to first event between the defined patient groups; matched-pair comparison (propensity score matching) between the different groups of patients (treatment strategies) and multivariate analysis using time to event (Cox proportional hazards model) as the dependent variable.
The project targets stroke survivors to investigate the effect of augmented feedback (using robotic force cues and visual feedback) on their upper limb reaching patterns and trunk compensatory movements.
Stroke remains the most dangerous and frightening complication of atrial fibrillation (AF). Numerous factors predisposing to peripheral embolism in patients with AF have been well defined, documented and included in the CHA2DS2VASC score. Although proper anticoagulation minimizes the risk attributable to "known" risk factors, stroke may still occur. Thus, "unknown" risk factors may play an important role in stroke risk stratification in patients with AF. The investigators assume that one of the important "unknown" risk factor is left atrial appendage (LAA) morphology. The ASSAM study is planned to include 100 patients after ischemic stroke or transient ischemic attack (TIA) and known status of anticoagulation at the time of stroke. The control group will consist of 100 patients scheduled for AF ablation without a history of stroke or TIA.
The Michigan Stroke Transitions Trial (MISTT) is a patient-centered randomized control trial that aims to improve the experience of stroke patients after they return home. The MISTT study will test the effect of two complementary interventions against usual care. The two interventions include: a) Stroke Case Managers (SCMs) who are trained social workers, and b) an online informational website or portal. The 12 week intervention period begins when the stroke patient returns home from the hospital or rehab facility. The SCMs will conduct at least 2 home visits with the patient (one within 3-4 days and one around 30 days) along with weekly follow-up telephone calls. Supplemental home visits will be used as necessary over the 12 week period. At the first home visit the social workers will conduct a comprehensive in-home assessment and link patients and caregivers to local resources as necessary. Patients also assigned to the website will have access to a patient-centered online information and support resource called the Virtual Stroke Support Portal (VSSP). The investigators hypothesize that this personalized case management program will reduce patient and caregiver needs, improve quality of life, and decrease caregiver stress. The MISTT study will enroll 315 acute stroke patients discharged from 3 Michigan hospitals and will be completed by the end of 2017.
