Active clinical trials for "Stroke"

This project is a cross-sectional, observational mono-center study with prospective data collecting. This study aims to further explore quality of upper limb movement in relation to characteristics of visuospatial exploration in stroke subjects and healthy subjects by a applying comprehensive measurements of clinical scales and kinematic data in capacity- and performance-based activities. The results will contribute to assessing and monitoring quality of upper limb movements and visuospatial attention and their relationship.

Ischemic stroke is the leading cause of acquired disability among adults, and one of the main causes of death. In Switzerland, the approved time window for stroke treatment with intravenous thrombolysis after symptom onset is 4.5 h. Even within the 4.5 h time-window, however, the benefit of treatment strongly decreases as time passes. Moreover, only around 10% patients receive thrombolytic treatment, since patients with stroke arrive too late to the hospital (prehospital delay). Despite efforts to educate the community on the symptom of stroke, prehospital delay did not decrease over time, and the reasons remain incompletely understood. Prehospital delay reduces the proportion of patients with ischemic stroke treated with thrombolysis, and reduces the odds of favorable outcome among the minority treated with thrombolysis. This prospective cohort study aims at understanding the causes of prehospital delay among patients with acute ischemic stroke. Trained study-nurses will interview, at the bedside, patients and proxies along a standardized questionnaire on prehospital delay. Avoiding modificables causes of prehospital delay may increase the thrombolysis rate and improve outcomes after stroke.

By developing an affordable mobile service robot for therapeutic activities in a health center environment, this project addresses the issue of both the high cost and man-power required to provide rehabilitation for stroke survivors and other patients. Our goal is to measure users - clinician and patient - responses to a telepresence robot, VGo, that has been modified with a humanoid torso robot, NAO, to facilitate remote communication between the patient and clinician, and to complete supervisory exercise coaching.

Orofacial impairment following stroke frequently involves a reduced chewing performance and dysphagia. This study investigated the sensitivity of oral tissues following stroke and its potential impact on chewing efficiency. The following two Null-hypotheses (H0) were tested: i. Post-stroke patients do not show a reduced intra-oral sensitivity compared to a healthy controls. ii. Intra-oral sensitivity is not correlated to chewing efficiency.

The aim of this study is to describe the population of patients admitted to the ICU in neurosurgery for stroke requiring secondary care in intensive care and their future.

Stroke is the second most frequent causes of mortality in the word after cardiovascular disease and the most frequent cause of disability. The majority of strokes are ischemic (87%). Ischemic stroke may benefit from efficient therapy if the delay from stroke onset not exceeds 4H30 (intra-venous thrombolysis). In case of irreversible cerebral lesion, the long term functional recovery is largely dependent from the ability of the brain to reorganize. Conventional magnetic resonance imaging represents the most sensitive tool to diagnose stroke at the acute phase. However, up to now, no imaging tool is available to determine the time of stroke onset. Moreover, no imaging tool is available to precisely quantify the functional and structural plasticity mechanisms occurring after stroke. The main objective of the present study is to test the accuracy of sodium MRI to determine the time of stroke onset. The secondary objectives of the study are to determine the ability of non-conventional MRI techniques to quantify the degree of tissue damage and brain reorganization after stroke. Thirty patients will be included during the first 24 hours after stroke onset. Multimodal MRI (including perfusion MRI, sodium MRI, resting-state functional MRI, high resolution anatomical MRI) and clinical evaluation will be carried on at the inclusion, after 24 hours, at 3 months and at 12 months.

To determine the incidence and predictors of augmented renal clearance (ARC) in patients with hemorrhagic stroke.

The purpose of this study is to determine whether Magnetic Resonance Imaging may predict the risk of Intracerebral Hemorrhage for patients with ischemic stroke who receive indefinite oral anticoagulation

Observational Study to investigate the technical feasibility, implementation into current diagnostic and treatment pathways and the diagnostic accuracy of the remote patient assessment by using mobile telecommunication ahead of hospitalization.

In chronic stroke patients, brain network reorganization and recovery mechanism are investigated after stroke onset using functional MRI and diffusion tensor imaging analyses.
