Active clinical trials for "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.

Our study aims to explore the value of new imaging technique package in predicting early neurological deterioration (END) as well as 90-day unfavorable outcome in patients with acute ischaemic stroke.

Quality of care depends strongly on oral communication with patients. Stroke patients, who have language disorders, have understanding difficulties, but also have difficulties in expressing their needs and in being understood. Available tools do not allow a professional consensus on the assessment of patients' ability to answer reliably to questions asked by caregivers. The investigators propose an answer reliability assessment tool based on yes or no questions. The goal of the present study is to define an optimal score for defining the test positivity, as a compromise between sensitivity and specificity, and by emphasizing the negative predictive value.

A survey was conducted among physiotherapists and occupational therapists working with stroke patients. The survey consisted out of 30 questions enquiring personal information and upper limb specific topics divided in 3 sections: (1) Passive mobilization, (2) Active exercises and (3) Immobilization. The survey took approximately 20 to 30 minutes to complete. The survey for stroke survivors was divided in seven sections: (1) Personal information (2) Motor recovery of the upper limb and expectations on upper limb recovery; (3) Comfort, pain and quality of life (QoL); (4) Immobilization ; (5) Physiotherapy; (6) Occupational therapy; (7) Nursing (only for patients less than 6 months after stroke). The length to complete the survey was also organized to be achieved in 20 to 30 minutes.

This is a single institutional registry database for the patients with stroke and cerebrovascular diseases. Stroke is the fifth leading cause of death in the United States. Despite extensive research, most of the patients die or suffer from varying degree of post-stroke disabilities due to neurologic deficits. This registry aims to understand the disease and examine the disease dynamics in the local community.

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.

This is a multi-centre, prospective cohort study. The aim of this study is to investigate causes, risk factors, clinical course, management and outcomes of severe ischaemic stroke in a real-world setting in tertiary hospitals in China. Patients with acute ischaemic stroke from nine tertiary hospitals in western China will be recruited. Participants will be visited within 24 hours after admission, on day 3, day 7 and at discharge, to collect their clinical data, blood biomarkers, and brain imaging. A structured telephone interview will be conducted for each participant at 3 months and 1 year after stroke onset, respectively, to collect their functional outcomes. In-hospital outcomes include haemorrhagic transformation, brain oedema and death, 3-month and 1-year outcomes include survival status (death or survival) and functional outcome (scores of modified Rankin scale, mRS).

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.
