NCT ID: NCT05189509 Not yet recruiting - Stroke, Ischemic Clinical Trials

EXtending the tIme Window of Thrombolysis by ButyphThalide up to 6 Hours After Onset (EXIT-BT)

Start date: January 15, 2022
Phase: Phase 2
Study type: Interventional

To date, the time window of intravenous thrombolysis is limited within 4.5 hours of stroke onset. Although EXTEND study has proved that intravenous thrombolysis can be extended from 4.5 to 9 hours, but the eligible patients must be selected by CTP. Thus, it is of clinical importance how to extend the time window of intravenous thrombolysis, which can benifit more patients. The current trial aims to investigate the effect of intravenous thrombolysis with TNK from 4.5 to 6 hours in ischemic stroke with help of Butyphthalide, which was found to be neuroprotective.

NCT ID: NCT05187559 Recruiting - Stroke, Ischemic Clinical Trials

Effectiveness of a Neuromuscular Exercise Program and Visual Feedback in the Management of Body Position for Stroke Survivors

Start date: December 1, 2021
Phase: N/A
Study type: Interventional

The aim of the biomedical research is to evaluate the changes of body position management during standing and walking for stroke patients, using innovative training methods during the rehabilitation.

NCT ID: NCT05179473 Recruiting - Stroke, Acute Clinical Trials

Prognosis and Diagnosis of Spasticity in Acute-post Stroke Patients

Start date: June 17, 2021
Study type: Observational

Spasticity, or greater muscle resistance, is a major disabling condition following stroke. Recovery of lost motor function in patients with stroke may be affected by spasticity, which most commonly develops in elbow and ankle muscles. However, despite its clinical relevance, the natural development of spasticity over the first 3 months after stroke is not clearly understood. Indeed, common clinical measures of spasticity such as the Modified Ashworth Scale (MAS) do not take into account the neurophysiological origin of spasticity and lack reliability and objectivity. The objective of this study is to examine the natural history of the development of spasticity among patients with stroke over the first 3 months using a new neurophysiological measure (TSRT, the tonic stretch reflex threshold angle) and its velocity sensitivity (mu) in comparison to MAS and other common clinical tests. In addition, detailed brain imaging will be used to understand the relationship between damage to brain regions relevant to the development of spasticity and TSRT/mu values. It is hypothesized that 1) TSRT/mu will indicate the presence of spasticity earlier than MAS/clinical tests; 2) TSRT/mu measures will be more closely related to motor impairments and activity limitations than MAS; 3) the lesion severity (identified by imaging) will be related to the change in TSRT/mu values. Outcomes will be measured in a pilot cohort of 12 patients hospitalized for first-ever stroke. Measurements will be taken at the bedside within the 1st week of the patient's admission and will be done once per week for 12 weeks with a follow-up at week 16. Brain Imaging will be done around the 6th week post-stroke.

NCT ID: NCT05173896 Not yet recruiting - Stroke, Ischemic Clinical Trials

Improving Cerebral Blood Flow and Cognition in Patients With Cerebral Small Vessel Disease. The ETLAS-2 Trial

Start date: December 2021
Phase: Phase 2
Study type: Interventional

In a randomized controlled trial the feasibility and effect of three months treatment with daily tadalafil, on cerebral blood flow/reactivity and cognition, is investigated in patients with cerebral small vessel disease.

NCT ID: NCT05140148 Not yet recruiting - Stroke, Ischemic Clinical Trials

Promoting Recovery After STroke With Amantadine

Start date: January 1, 2022
Phase: Phase 2
Study type: Interventional

The investigators aim to examine whether amantadine can help patients recover from stroke. This will be a blinded randomized clinical trial (RCT). Patients will be randomized post-ischemic or hemorrhagic stroke either to the placebo arm or amantadine arm. Patients will be on study drug or placebo for 1 month but will be enrolled for 3 months total. At various time points patients will be examined and fill out questionnaires to determine level of stroke recovery.

NCT ID: NCT05132465 Recruiting - Stroke, Ischemic Clinical Trials

Liverpool-Heart and bRain Project Stroke Cohort

Start date: October 12, 2021
Study type: Observational [Patient Registry]

What research question is being addressed? Can improve the prediction of adverse outcomes be improved for people following a stroke to optimise their treatment and care? How is it of relevance and importance to patients and public? Following a stroke, people are at a higher risk of developing certain conditions including heart failure, another stroke and atrial fibrillation, a type of irregular heart rhythm. In the proposed study, the investigators will look at factors which may increase a person's risk of such conditions following stroke. From this, the investigators will determine if risk scores for these conditions can be improved for people post-stroke. This could help doctors decide what treatments are best. Who would be eligible? All adults at participating hospitals who have had an ischaemic stroke (where the stroke is caused by loss of blood flow to the brain) or a transient ischaemic attack ('mini-stroke') confirmed by a stroke doctor. All patients will be asked to take part in the study, or their family members may be asked to provide advice on their behalf if the patient is unable to. Where is the study being conducted? At participating hospitals in England and Wales. What will the participants undergo? At the time of stroke, patients have a lot of information collected about their health, the investigators will copy information from patient's medical records about their health after they agree to take part in the study. Patients or their family members will also be asked to complete some additional brief questionnaires about their quality of life, wellbeing and fatigue. Some questionnaires such as for cognitive function are already collected for patients following a stroke, but where this information has not been collected, it will be collected for the study. The investigators will ask the patients if they can be contacted in 12-months to repeat the questionnaires and information collected about their health.

NCT ID: NCT05121155 Completed - Stroke Clinical Trials

Brain Skull Deformation as a Non-invasive Intracranial Pressure (ICP) Measure

Start date: March 1, 2019
Study type: Observational [Patient Registry]

Background: Although placement of an intra-cerebral catheter remains the gold standard method for measuring intracranial pressure (ICP), there are several limitations to the method. Objectives: The main objective of this study was to compare the correlation and the agreement of the wave morphology between the ICP (standard ICP monitoring) and a new nICP monitor in patients admitted with stroke. Our secondary objective was to estimate the accuracy of four non-invasive methods to assess intracranial hypertension. Methods: We prospectively collected data of adults admitted to an intensive care unit (ICU) with subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH) or ischemic stroke (IS) in whom invasive ICP monitoring placed. Measures had been simultaneously collected from the following non-invasive indices: optic nerve sheath diameter (ONSD), pulsatility index (PI) using transcranial Doppler (TCD), a 5-point visual scale designed for Computed Tomography (CT) and two parameters (time-to-peak [TTP] and P2/P1 ratio) of a non-invasive ICP wave morphology monitor (Brain4care[B4c]). Intracranial hypertension was defined as an invasively measured ICP > 20 mmHg for at least five minutes.
