Active clinical trials for "Stroke"

The Physical Activity Scale for the Elderly (PASE) is a self-report questionnaire on exercise, home, and work-related physical activities performed during the last week. PASE has shown to be reliable and valid in different populations of people between 65 and 100 years of age and after stroke. However, its validation on stroke was based on another self report questionnaire that assess physical activity called ''Senior Fitness Test''. Since accelerometers are more objective methods to assess PA, to the best of our knowledge, self-report physical activity questionnaires should be validated based on accelerometer derived physical activity data. The aim of this study is to validate PASE in patients with stroke based on accelerometer data.

Intravenous thrombolysis is recommended within 4.5 hours of stroke onset. The aim of the study is to evaluate whether a hypodensity on native CT within the virtually entire area of hypoperfusion on perfusion CT, i.e. hypoperfusion-hypodensity mismatch, identifies patients within the time window of thrombolysis in a multicenter cohort. The investigators hypothesize hypoperfusion-hypodensity mismatch will identify patients ≤ 4,5 hours of symptom onset with >70% specificity and >85% positive predictive value.

Rationale: Depression is a frequent complication after a stroke. In stroke guidelines several recommendations focus on early screening, and treatment off depression after stroke. Introducing clinical practice guidelines into routine daily practice however, is a difficult process. In order to make the recommendations applicable to clinical practice a toolkit was developed (the Post Stroke Depression-toolkit), which provides assessment tools for the early detection of depression after stroke, and a set of interventions in case of a positive screening for (risk on) depressive symptoms. Objective: to investigate the feasibility of the Post Stroke Depression-toolkit in daily practice. Study design: An explanatory mixed-methods, before-and-after study design. Study population: Nurses working on the neurological wards of one university hospital and two general hospitals in the Netherlands were included in the study. Additionally, data were obtained from patient charts.

Introduction: the source of embolic stroke , in thrombotic embolism , is of unknown origin in 30-40% of cases. Fortunately , Mechanical thrombectomy provide a direct method to retrieve the stroke-incriminated clots from stroke patients for possibility of exo-autopsy analysis.

Patients admitted to the in-patient rehabilitation center with a diagnosis of stroke will be recruited into the study. The participants will wear two activity monitors (one commercial grade and one research grade) for the duration of their rehab stay. Data from the monitors will be correlated with rehab outcomes, therapy units billed, and length of stay.

Ischemic strokes are the first cause of handicap in adult people, the second cause of dementia and the third cause of death in France. Brain Magnetic Resonance (MR) initial assessment is mandatory to get the right diagnosis, to exclude hemorrhagic lesions and to determine the best treatment. The conventional diffusion weighted imaging sequence is used to establish the diagnosis and to estimate the volume of ischemic lesions. The perfusion weighted imaging sequences are also used to assess the diffusion-perfusion mismatch which is supposed to be the ischemic penumbra corresponding to territories that could be saved with appropriate treatments. IntraVoxel Incoherent Motion (IVIM) is a multi-b diffusion sequence which allows to extract four quantitative variables (D, D*, f, ADC) related to the true molecular diffusion and correlated to the microvascular perfusion. It's a quick sequence with no need of contrast injection and allowing a perfect coregistration with the true diffusion. It has been validated in many pathologies but not in acute strokes. The feasibility of this sequence in acute ischemic strokes has already been assessed with interesting results. The study aims to assess the correlation between the quantitative values of IVIM at initial MR exam and the modified Rankin Scale (mRS) score 3 months after an acute ischemic stroke.

This Observational study aims at the evaluation of stroke subjects with an inertial measurement unit (IMU) during the execution of a 6-Minute Walking test, to evaluate the associations between the kinematic parameters retrieved trough an IMU and the classical outcome scales. Moreover compare the stroke subjects with age-matched healthy subjects, and detect the differences of gait kinematic.

The purpose of this study is to test the relevance, satisfaction and ease-of-use of an online mindfulness intervention among stroke survivors and their caregivers. Quality of life, depression, anxiety, stress and sleep quality will be assessed before, after and at 1 month after the intervention. After the intervention, participants' feedback about the usability and the satisfaction with the intervention and the online program will be gathered. Based on participants' feedback, changes to the intervention will be made to obtain a final version.

"mini-BESTest (Turkish version)", "Berg Balance Test", "Timed Up and Go Test" and "Functional Reach Test" will be used for balance measurement in patients and the correlation of the mini-BEST with these tests will be checked.

In China, stroke is among the highest morbidity and mortality, especially in senile population. Most of those patients had survived with various degrees of cerebral dysfunction; among them about 50% were motor deficit. Previous in vitro studies indicated that recovery of motor function after stroke were related not only to axonal regeneration or synapse reformation, but also functional reorganization of adjacent areas and other functional associated areas. The previous fMRI studies shown that the cerebral motor cortex possess the natural ability of self compensation and self reorganization in the situation of brain damage. It was characterized by equally bilateral activation in acute stage to partial ipsilateral activation and major contralateral activation in subacute stage to contralateral activation in chronic stage. We plan to recruit first-episode acute cerebral infarction patients with single lesion on middle cerebral artery supply area and age and sex matched healthy volunteers. All the patients are going to assess in three different sessions (V1, 3 days after the onset of complaint, V2,30 days after onset of complaint; V3, 90 days after onset of the complaint ) with both clinical check as well as fMRI scan. The clinical assessment including dynamometer and finger tapping test to evaluate the strength and the flexibility of each upper legs and it also included the corresponding scales to exclude poststroke dementia and moderate and serious poststroke depression. The fMRI is scanned by using bilateral arm motor tasks. Motor cortex activation regions, activation of voxel between healthy controls and patients in different checkpoint are collected. The purpose of this study is to investigate the dynamic process of motor cortical functional reorganization after cerebral stoke using functional magnetic resonance imaging combined with the behavior assessment. Meanwhile，we also studied the differences of motor function recovery and motor cortex compensation between dominant hemisphere and non-dominant hemisphere after stroke. Therefore, we could provide a theoretical basis and build up a useful evaluation system for rehabilitation after stroke and other arious cerebral injury.
