Active clinical trials for "Stroke"

Aim study 1:Assess the accuracy of PREP2 when applied in a subacute rehabilitation setting. Aim study 2: Prediction of real life UL use. Method: A prospective cohort study. Main outcome measure study 1: Action Research Arm Test (ARAT), measuring UL motor function. Main outcome study 2: use ratio between affected and unaffected UL measured by accellerometer. Secondary outcome measure: Fugl-Meyer Motor Assessment for UL (FM).

Healthy individuals, after reading and signing the free and informed consent will be submitted to a single session to obtain the normal neurophysiological measures and thus compare with those obtained in individuals with PD. Healthy and post stroke patients will be submitted to a neurophysiological evaluation through transcranial magnetic stimulation (TMS) and electroencephalography (EEG). The post stroke patients will also performed the evaluation trought the fugl meyer scale.

The aim of this study was to investigate differential plastic changes of fractional anisotropy (FA) in the corticospinal tract (CST), the intrahemispheric corticocortical tract from the primary motor cortex to ventral premotor cortex (M1PMv) and the corpus callosum (CC) from 2 weeks to 3 months after stroke according to BDNF genotype.

Prediction of recovery from stroke can assist in the planning of impairment-focused rehabilitation. To achieve better prediction for clinical purposes, this study investigated a new prediction model with low inter-individual variability and high accuracy using neuroimaging techniques.

The hypothesis is that in patients with stroke, abnormalities of retinal microvascularization shown on color fundus photography and the depletion of retinal capillary density evaluated by OCT-A are markers of acute impairment of microcirculation of the central nervous system and are correlated with lesions on brain imaging. Patients hospitalized for stroke MRI-confirmed, will be included. An ophthalmologic assessment including color fundus photography (CFP) and OCT-A will be carried out after stabilization and at 3 months follow-up. Outcomes assessor will be blinded.

Accurate diagnosis of stroke due to large vessel occlusion (LVO) is an essential step in providing acute stroke care to a community. The gold-standard for diagnosis LVO is brain imaging, which is impractical in the pre-hospital setting. A non-invasive method to detect LVO is needed. Using highly sensitive accelerometers, one can measure the "HeadPulse"- tiny forces exerted on the skull from the cardiac contraction. This study tests the hypothesis that LVO alters the HeadPulse characteristically. Analysis of these data along with the subjects vascular status (LVO vs. non-LVO as measured by CT angiography) will be used to create a model that can predict LVO status in suspect stroke subjects.

The goal is to review patients with known atrial fibrillation who suffered a stroke or transient ischemic attack (TIA) to incorporate any structural heart abnormalities into the overall clinical picture. A better understanding of the additional risk of a stroke or TIA in patients with specific structural abnormalities may be beneficial in guiding future treatment decisions.

Retrospective cohort study of consecutive patients investigated in a neurorehabilitation ward after a first hemispheric stroke. Postural and gait disorders in relation to referential of verticality have been analyzed in routine care.

The incidence of Stroke in France is about 150 000 per year. Stroke represents the leading cause of long-term disability. The specificity of stroke is the sequelae polymorphism that can occurs: physical disability, cognitive deficit and sensitive trouble. Then this large extend of sequelae may have a different impact on daily life. Therefore, we have to consider the individual's own resources and in his whole environment to face the situation. We suppose that each situation, each post-stroke disability will have a different social impact in stroke survivors and their caregivers. Nowadays, Barthel Index and Rankin scale are the standards for the assessment of the stroke impact on survivors' daily life. However, what is the real impact of an activity limitation in daily life? How consider the psychosocial impact of stroke only with functional indicators? For this study we will consider handicap and disability in a societal way. In fact, the WHO developed in 2001 the International Classification of functioning, disability and health that allows to bring the concept of participation restriction, this is to say the consequences of a disability in the real life. The ICF allows to bring a conceptual framework of participation restriction. Psychosocial consequences of stroke are relatively unknown especially in France. According to our hypothesis, patients with major disabilities and their caregivers will experience more psychosocial consequences and participation restriction in terms of emotional health, quality of life and burden. Also, we hypothesize that stroke severity, the typology of disabilities (motor, cognitive and sensorial) will have a different impact on patients and proxys' lifes in terms of psychosocial consequences, participation restriction and quality of life. TYBRA study is a prospective multicentric cohort study that mixes qualitative and quantitative approaches. The first aim of the quantitative approach is to explore factors related to patients and their caregivers at 6 months that predict participation restriction at 12 months post-stroke. The first aim of the qualitative study is to explore the experience of stroke in minor stroke patients and their proxys.

To further develop interventions, the investigators need a better understanding of which task requirements (i.e. size or weight of object, location in workspace, etc.) drive a person after stroke to use 2 hands (as opposed to 1), and how the severity of their injury impacts this relationship and compare this to reaching in age-matched healthy controls subjects. A better understanding of this relationship will promote more informed development of rehabilitative interventions. This study proposes to explore in people after stroke and healthy controls: i.) how specific functional tasks requirements relate to 1 vs. 2 handed use, and ii.) how stroke severity impacts this arm use. We are proposing to study 15 individuals more than 6 months after stroke in the CSU Motor Behavior Lab for a two x 3 hour session of task-related reaching in sitting and 33 age matched (double sample size) healthy controls. The investigators will systematically vary task requirements (i.e. object size or weight, location in workspace, etc.), and record use of 1 versus 2 hands using videotaping as well as recording of quality of arm movement (kinematics) and muscle activity (EMG) in both arms.
