Active clinical trials for "Stroke"

In this cross-sectional study we will compare the limits of stability in non-ambulatory participants post stroke compared to healthy controls. This will be done by placing participants in a seated position on a force platform, that will measure centre of pressure displacements during a leaning task in multiple directions. The results of the limits of stability test will be compared to standard clinical Measures of trunk control and functional balance, to see if there is a relationship between both ways of measuring. And how balance and trunk control are affected in the subacute stroke population.

A non-interventional observational clinical study to document the clinical course of patients at 12 months or more following an ischaemic stroke

Upper limb recovery after stroke is highly predictable early after stroke. Nijland et al. showed that based on two simple clinical bedside tests - 'Shoulder Abduction' and 'Finger Extension' (the so called 'SAFE model' [Stinear et al., 2012]) - measured within the first 72 hours after stroke, ~87% of the patients could be correctly classified as either regaining or not regaining some dexterity (recoverers or nonrecoverers, respectively) (Nijland et al., 2010). This kind of information regarding the patients' functional prognosis allows proper discharge planning, setting realistic rehabilitation goals, and adequate patient information. However, the length of hospital stay after stroke has been decreasing. Therefore, knowledge is needed regarding the ability to make an accurate first prediction within the first 24 hours after stroke onset while using simple clinical bedside assessments. This would facilitate an earlier triage and with that, an accelerated and smooth transition of patients within the stroke care continuum. In addition, a first prediction within 24 hours poststroke has the potential to decrease health care expenses, as length of hospital stay after an acute stroke is ~30% of the total costs (i.e., direct and indirect costs) associated with stroke (Roger et al., 2012; Fattore et al., 2012). The primary objective of aRISE is to determine the ability of the behavioral biometric impairments 'Shoulder Abduction' and 'Finger Extension' measured <24 hours poststroke to predict outcome of upper limb capacity 3 months after stroke. The secondary aim is to investigate the the added value of other simple clinical bedside tests for predicting outcome of upper limb capacity 3 months poststroke. aRISE is a prospective longitudinal observational cohort study of 40 first-ever ischemic stroke patients, who will be assessed <24 hours, 7 days and 3 months after stroke onset.

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.

Difficulties with walking is a common and distressing problem following stroke and can lead to reduced independence. Research suggests that using an auditory cue, such as a regular beat or pulse, as part of rehabilitation can improve walking. It is also recommended that early rehabilitation following stroke delivers the bestoutcome for patients. Study aim:To determine whether the use of auditory cueing in early stroke rehabilitation is feasible during a balance and gait therapy programme. Study participants: Adults following acute stroke with walking problems. Participants must be able to sit unsupported and stand with assistance of 1 or 2 people. They will be recruited from the acute stroke unit at North Tyneside General Hospital 2 days to 4 weeks following stroke. A total of 12 participants will be recruited. Study setting: Acute stroke unit - North Tyneside General Hospital and participants homes if they are discharged within the study period. Intervention:Participants will receive auditory rhythmical cueing intervention targeting balance and gait for 30 minutes x5 / week for 3 weeks within the physiotherapy gym on the stroke unit or at home if discharged within the intervention period. The 30 minutes will consist of balance exercises and walking practice using auditory cueing with a metronome. Measures:1. What the participants and the therapists think of the intervention will be assessed by questionnaires. The questionnaires contain open and closed questions and have been developed specifically for this study. 2.The stroke survivors trunk control, balance and walking will be assessed before and after the intervention. Study Duration: 12 months Future Plans: This study will be used to inform a larger study testing if the intervention works and how much it costs

Stroke is a major public health issue in developed countries. A full etiological work up within a short time is critical to implement the appropriate preventive treatment. The etiological work up is actually based on a clinical examination and on a group of paraclinical examinations. The realization of the standard strategy is time consuming, and increase the cost of the medical care. A non-invasive one-shot examination of the heart, the aorta and the cervical and intracranial arteries (cci-MRI) could overcome these disadvantages.The investigator therefore propose to carry out an overall assessment of the performance of the cci-MR in the etiological work up of ischemic strokes and TIAs compared to the reference strategy

The aim of the present study was to quantitatively assess the risk factors that may affect the re-occurrence of a CVD event and the use of a commercially available mobile application Samsung Health for the assessment of parameters of exercise tolerance and the ECG M-Trace Base II application for the assessment of cardiological parameters.

This epidemiological survey is to analyze the prevalence rate of stroke and exposure rate of risk factors in sampling population aged 40 years and over (born before December 31,1975) in Dehui City, to provide scientific basis for pertinent prevention and control of stroke in Jilin Province, and to provide valuable data for the high-risk groups to carry out regular follow-up and standardized management.

The study focus on the elderly patient (older than 80 years of age) who had acute ischemic stroke and received mechanical thrombectomy. The investigators analyze different factors in the stage of before, between, after procedure and trying to figure out if there is any difference between the 30-day-mortality group versus non-30-day-mortality group.

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.
