Active clinical trials for "Stroke"

In order to discover dysphagia scales, which shows meaningful predictability of aspiration and functional health status in patients with acute stroke, authors plan to find out more predictable indicators than existing penetration-aspiration scale (PAS) to validate their predictions and their internal and external validity over 6 months following stroke .

Contrast-enhanced ultrasound(CEUS) of carotid artery plaque is a novel method that enabled direct visualization of neovessels in the vulnerable plaque. Plaque enhancement with CEUS showed correlation with the histologic density of neovessels within the carotid plaque and the previous cardiovascular events. Vulnerable plaques with a high risk of thromboembolic complications and rapid progression is associated with acute ischemic stroke. The prognostic value of vulnerable carotid artery plaque depicted with CEUS has not been fully investigated. The purpose of this study is to define prognostic value of plaque enhancement on carotid CEUS in acute stroke patients. Research question is; in acute ischemic stroke patients with ipsilateral carotid plaque as probable etiology of stroke, is the presence of carotid plaque enhancement on CEUS independent predictor of future stroke.

The investigators combined the mRS questionnaire and BI questionnaire and then developed a telephone interview form as a simple questionnaire with internal rules. The main purpose of this study is to evaluate the validity and reliability of the telephone interview form when compared with face-to-face assessment in clinically stable patients with stroke.

Our study was planned to investigate the reliability validity of the Movement Imagery Questionnaire- RS in acute stroke patients. For our study, the Turkish version of the Movement Imagery Questionnaire-RS will be established first. Then, the reliability and validity of the questionnaire in acute stroke patients will be examined. The study included 70 stroke patients hospitalized in the Stroke Unit of the Neurology Department of Hacettepe University Hospitals and individuals between 50-75 years of age who do not have any disease in Ankara.

The aim of the study is to investigate the ability to recall information given during informed consent on intravenous thrombolysis in patients with acute ischaemic stroke.

Despite novel acute therapies the global burden of stroke remains high worldwide. Targeting the immune response after stroke has the potential to improve recovery in all stroke patients. Experimental studies suggest important roles for T-lymphocytes, especially anti-inflammatory regulatory T cells, in the evolution of stroke and neurological deficit. Objectives of this study are to either confirm or refute the hypothesis that a subset of brain regulatory T cells exists in humans and expands after stroke and to identify immunological biomarkers that can be used in stroke clinical trials targeting the adaptive immune system.

Stroke ranks 3rd among disability-causing diseases worldwide. Following a stroke, loss of lower extremity motor function causes serious gait disturbances. The walking activity is the basis for daily and social engagement activities. Mobility (locomotion) ability; gait analysis can be evaluated with tests and reports examining walking performance. ABILOCO is also a questionnaire developed by Caty et al., evaluating mobility and locomotion in individuals after stroke. The aim of this study is; To investigate the validity and reliability of the Turkish version of the ABILOCO questionnaire developed to evaluate mobility in patients with stroke. The sample of the study will be literate individuals who have had a stroke who applied to the Neurology Unit of Ankara Hacettepe University Faculty of Physical Medicine and Rehabilitation. Demographic information of the cases will be recorded. ABILOCO questionnaire will be adapted to Turkish. The validity and reliability comparison of the ABILOCO questionnaire with the Berg Balance Scale and Timed Get Up and Go Test will be performed.

Upper limb impairment occurs in approximately 70 to 80 per cent of adults post stroke. These impairments will have consequences on functional performance in activities of daily living and hence quality of life. Assessment of upper limb function is a component of rehabilitation that contributes to the selection of optimal interventions according to patient individualized needs. The Arm Activity Measure (ArmA) provides a standardized assessment of upper limb passive and active perceived performance that is only available in it's English version. The aim of this study is to translate and conduct a cross-cultural adaptation of the ArmA is order to investigate its psychometric properties through a validation study among stroke patients.

The emergency setting for acute neurological conditions, such as stroke, is peculiar due to time pressure and limited resources for further diagnostics. Clinical skills are essential for swift and accurate bedside diagnosis and thus are the basis for early and correct treatment. This is especially evident in the context of computed tomography being the standard neuroimaging method world-wide with its limitations for detecting smaller infarcts, strokes in the posterior fossa and reduced sensitivity for stroke mimics, such as epileptic seizures or migraine aura. To date, the accuracy of clinical bedside diagnosis of stroke by neurologists verified by magnetic resonance imaging (MRI) in the emergency setting has not been studied in detail. In order to improve clinical diagnosing and future treatment it is essential to quantify the accuracy of clinical diagnosis of stroke in the emergency setting ("how good are neurologists?") and to assesses whether there are any differences between experienced staff neurologists and junior physicians.
