Active clinical trials for "Stroke"

Previous research has shown there wasn't inevitable relationship between mismatch area and infarct growth according to Volumetric-subtraction mismatch volume.The recently published on Stroke paper has proposed Coregistration mismatch to calculate the mismatch to replace ischaemic penumbra, and it reignites hope for clinical application of the PWI/DWI mismatch. But the correlation between the mismatch, calculated by Coregistration mismatch method,and the clinical outcome of the patients with acute ischemic stroke is still unknown. so the investigators plan to conduct a prospective observational cohort study.

Stroke is the most common cause for motor disability in the grown-up population in the Western world. In Sweden > 80 % are above 65 years of age at onset (1).Areas in the brain, controlling the movement in the upper extremity (UE) are often damaged at a stroke, which leads to impaired function. This impairment of the UE often leads to limitations in activities of daily living and reductions in the level of social activities; therefore, interventions that will improve function are needed to reduce the consequences for the person living with stroke. The time course of recovery of the UE is not clear and therefore the optimal timing of the intervention for the person and its content (ways of intervention) uncertain. The investigators have developed objective assessments of motor performance with new technology (kinematic analysis and virtual reality with haptics). Since having an impaired UE often results in reduced capacity in daily living and social activities, this might lead to decreased participation. To complement the traditional focus on body function, there is a need for assessments of the person's activity level and participation, as well as self-perceived function. The results from this study will lay the ground for an intervention study focusing on improved function in the upper extremity.

A total of 144 stroke patients 6 -24 months post onset who are between 45 and 75 years old will be recruited. A randomized-blocks pretest and posttest control group design will be applied. Four groups will be involved in this project and the subjects will be stratified on two variables: impairment level of the hand and side of lesion. Randomization will be done in blocks of six and each block randomization scheme is within each stratum. Treatment regimens will be designed to ensure that patients in 4 groups receive equivalent intensity of treatment (5 days/week for 1.5 hours/day for 4 consecutive weeks) directly supervised by senior occupational therapists. Brain and movement reorganization will be evaluated with fMRI and kinematic instrument, respectively before and after the 4-week intervention period. Clinical measures on motor impairment, daily function and quality of life will be assessed before, immediately and six months after intervention. Two examiners blind to group allocation will collaborate to provide both fMRI and kinematic evaluations and one of them will administer clinical measures. Before being allowed to work with subjects, the examiner competence will be assessed by principle investigator and co-principle investigators. Multivariate analyses of covariance will be used to examine change in brain activation, kinematic variables and clinical measures as a function of intervention while controlling for pretest data, age and onset post stroke. Multiple regression models will be established to examine the possible predictor(s) for functional outcome of each rehabilitation approach. Canonical correlation analyses will be conducted to quantify the relationship between brain/motor reorganization and clinical measures.

The purpose of this study is to explore the severity of malnutrition and inflammation in Taiwanese hemodialysis patients.

our research team will develop a new CADL scale for stroke patients over the next three years. In the first year, we had established a CADL item bank of 50 items. The investigators will administer the 50 items on 300 patients with stroke living in the community. Then we will select 10 to 15 items from the item bank for the CADL scale based on the International Classification of Functioning, Disability and Health (ICF), the opinions of an expert panel, and Rasch analysis. It is anticipated that the CADL scale will have unidimensionality, an interval level of measurement, soundly psychometric characteristics, a reduced number of items, and ease of administration. In the second and third years, we will compare the psychometric properties of the CADL scale and the combined BI and FAI scale. The psychometric properties investigated will include reliability (e.g. inter-rater reliability, intra-rater reliability, and internal consistency), validity (e.g. concurrent validity, convergent validity, predictive validity and discriminant validity), and responsiveness. A total of 150 patients will be recruited. Both the CADL scale and the combined BI and FAI scale will be used on patients from the initial stage (within one month) to six months after hospital discharge. The results will be useful for researchers and clinicians to determine whether the CADL scale is better than the combined BI and FAI scale in stroke patients.

This study is going to comprehensively examine the psychometric properties of the three depression scales (Hamilton depression scale (HAMD), Hospital anxiety and depression scale (HADS), and Beck Depression Inventory (BDI)) in stroke patients over a period of three years.

Tripping over obstacles is one of the common movements in daily life and is the most frequently mentioned cause of falls in the elderly. Indeed, crossing obstacles is a more complex motor skill than walking, and ensuring sufficient clearance of an obstacle during locomotion requires accurate movement and appropriate modifications of the swing limb. However, little is known about the obstacle crossing deficits that following stroke, especially in good outcome and function independently strokes. It is still a mystery about motor control and motor plastic of central nerve system. The purpose of the study was to observe and quantify certain characteristics of the performance of subjects following stroke with good outcome to understand the damage of central nerve system how to affect motor control. The present study investigated selected spatial-temporal characteristics, kinematic variables and kinetic variables of the gait pattern to define further the problems in obstacle crossing following strokes. To quantify the deficits, we compared results from a group of subjects with stroke with a group of healthy subjects matched for age, gender, and height.

Multi-centre prospective study evaluating computed tomography angiography studies performed for stroke patients as a diagnostic and prognostic imaging biomarker.

Prevention of thromboembolic complications is an important part in the management of patients with atrial fibrillation (AF). European and American guidelines recommend the use of non-vitamin K antagonist oral anticoagulants (NOACs) over therapy with vitamin K antagonists (VKA) in most AF patients. The number of patients treated with NOACs has increased significantly during the last few years. In the primary randomized controlled trials leading to their approval, compared to warfarin, NOACs were shown to be either noninferior or superior for stroke prevention in AF, with similar or reduced rates of bleeding, especially intracranial haemorrhage. The aim of this study was to assess the frequency of oral anticoagulants using, espescially apixaban, dabigatran, and rivaroxaban, and the predictors of their prescription in a group of hospitalised patients with AF.

Limitation of range of motion in the shoulder joints is common in stroke patients. The causes are stiffness, CRPS, and frozen shoulder. The purpose of this study was to investigate the relationship between frozen shoulder and shoulder LOM in patients with cerebral infarction using ultrasonography.
