NCT ID: NCT04851457 Not yet recruiting - Ischemic Stroke Clinical Trials

One Pass Tirofiban In Management of Ischemic Stroke Thrombectomy In China

OPTIMISTIC
Start date: May 2021
Phase: Phase 2/Phase 3
Study type: Interventional

In recent years, the positive results of trials for mechanical thrombectomy (MT) have brought a new era for large artery occlusion patients, especially those beyond the time window of intravenous thrombolysis. However, interventional procedures can cause endothelial injuries leading to local activation of platelet aggregation and subsequent thromboembolic complications or early re-occlusion.Tirofiban is a specific antagonist of the platelet glycoprotein (GP) IIb/IIIa receptor, which is considered highly effective against the final common pathway of platelet aggregation and preventing vascular reocclusion. However, there is no consensus on if AIS patients treated with MT also benefit from intravenous tirofiban. This study aims to evaluate the effectiveness and safety of profiles of tirofiban during MT and provide reliable clinical evidence for the treatment of tirofiban in AIS patients.

The Effects of Optimization od tDCS Dosage on the Motor Function of Lower-limb in Patients After Stroke

Start date: June 7, 2021
Phase: N/A
Study type: Interventional

Currently, it is known that transcranial direct current stimulation (tDCS) can modulate cortical activity, being considered an important resource in the treatment of sequelae resulting from stroke. However, evidence of the effects of tDCS in the acute post-stroke period on lower limb motor recovery still remains scarce and inconclusive. Currently, a great variability of results has been perceived, in this sense there is a need for studies that perform dosage optimization, based on individual characteristics. Therefore, the present study seeks to evaluate the therapeutic effects of the optimization of the measurement of tDCS on the motor function of lower limbs in patients after ischemic stroke in a late subacute stage (3 to 6 months after the injury), compared to individuals undergoing sham tDCS. The study is a randomized, double-blind, sham-controlled clinical trial, with individuals after a stroke, recruited at a referral hospital in the metropolitan region of João Pessoa. After recruitment and initial screening, participants will be randomized into two groups: Group 1 - active stimulation and group - 2 sham stimulation. Participants will receive 10 sessions of tDCS, for 20 minutes, on alternate days (3 times a week), where the electrodes will be positioned over the primary motor cortex. 3 minutes of EEG at rest will be taken from each participant, and they will be instructed not to be actively involved in any cognitive or mental activity. In the first and last meeting, the evaluations will be carried out, the evaluated outcomes will be: motor function (Fugl-Meyer scale), functional connectivity (EEG), quality of life (SF-36) and level of functional disability (Rankin scale) . Statistical analyzes will be performed using the SPSS software (Version 20.0) and MATLAB 9.2.0 with a significance level of p <0.05.

Cerebral Blood Flow-guided Early Rehabilitation Intervention After Stroke: a Pilot Randomized Trial (STAND-OP)

STAND-OP
Start date: April 2, 2019
Phase: N/A
Study type: Interventional

The primary goal of most acute stroke interventions is to restore cerebral blood flow (CBF) in the affected region and prevent hypoperfusion during early clinical course. Diffuse optical technology offers a new opportunity for invasive, real time and bedside assessment of brain function biomarkers, including CBF. However, whether CBF monitoring can identify patients who are most likely to benefit from therapies is unclear Recently, it was suggested that the benefit of early mobilization (EM) after stroke on motor recovery may be outweighed by a deleterious effect on cerebral perfusion if cerebral autoregulation (CA) is impaired. Hypothetically, EM could improve recovery outcomes after stroke in selected patients based on CA function. Our objective is to investigate if EM leads to superior motor and functional outcome after stroke compared to standard care (SC) in selected patients based on optical biomarkers of CA and evaluate the feasibility of the clinical use of a novel transcranial optical monitoring system adapted to deliver biomarkers of CA at the bedside. The investigators designed a randomized controlled, open-labeled trial with blinded assessment of outcome end-points in a stroke unit of a tertiary stroke center. Patients with an ischemic or hemorrhagic stroke will be recruited and randomly assigned within 24 hours after symptoms onset to receive SC alone or EM in addition to SC. All patients will undergo optical monitoring of CA on admission to the Stroke Unit during the first mobilization. Randomization will be stratified by stroke severity and type of stroke. Clinical outcome will be assessed with the Postural Assessment Scale for Stroke (PASS) and modified Rankin scale at 90 days. Safety outcome will be assessed by recording the incidence of neurological deterioration, recurrence and falls.

NCT ID: NCT04847752 Recruiting - Ischemic Stroke Clinical Trials

Study of Predictive Factors Related to Prognosis of Patients With Ischemic Stroke Due to Large-artery Atherosclerosis

Start date: March 1, 2021
Phase:
Study type: Observational

This is a single-center prospective cohort study of predictive factors related to prognosis of ischemic stroke due to large-artery atherosclerosis. From March 1, 2021 to December 31, 2026, 1000 patients with ischemic stroke due to large-artery atherosclerosis who are admitted to the Department of Neurology or Neurosurgery, Tongji Hospital are going to be recruited. Detailed clinical data in emergency room and in-hospital will be obtained from the medical record reviews, and the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (mRS) score will be done by certified neurologists to assess the severity of the disease in acute stage and treatment outcome during the follow-up. All cases will undergo routine blood tests, brain magnetic resonance imaging (MRI) and cerebral vascular examination, such as TCD, CTA, HRMR or DSA. The investigators will analyze the in-hospital factors that could predict the outcome to provide more evidence-based suggestions in the treatment and prognosis of atherosclerotic ischemic cerebrovascular disease.

NCT ID: NCT04847089 Recruiting - Stroke Clinical Trials

Motor Imagery BCI Rehabilitation After Stroke

Start date: April 19, 2021
Phase: N/A
Study type: Interventional

This research project will investigate motor imagery training in stroke rehabilitation during which patients receive feedback in real time from their brain activity measured with ElectroEncephaloGraphy (EEG). The investigators hypothesize that the feedback training allows to internally stimulate brain motor networks in order to promote functional recovery of the hand.

NCT ID: NCT04846205 Enrolling by invitation - Stroke Clinical Trials

Relationship Between Sleep Apnea Syndrome and Patent Foramen Ovale Among Victims of Cryptogenic Ischemic Stroke

Start date: March 24, 2021
Phase:
Study type: Observational

Obstructive sleep apnea syndrome (OSAS) and patent foramen ovale (FOP) are considered as risk factors for stroke. OSAS generates a pressure increase in the right cavity during inspiratory efforts, which increases the number of right-left shunt embolus and therefore the risk of stroke. OSA and FOP are often thought as two separate entities, however, due to their high frequencies, they sometimes coexist and can influence the pathophysiology of each other. More researches are needed in this area to confirm this complex association and its role in triggering stroke.

NCT ID: NCT04845542 Not yet recruiting - Stroke Clinical Trials

Promoting Resilience in Stroke Survivor-carepartner Dyads (ReStoreD)

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

Affecting nearly 800,000 people in the US every year, stroke is a leading cause of long-term disability, and has serious consequences for stroke survivors and their carepartners. Our project uses a scientifically rigorous efficacy study to evaluate a remotely delivered 8-week dyadic (couples-based) positive psychology intervention to reduce emotional distress in stroke survivors and their carepartners. If successful, couples may be better emotionally equipped to cope with the sequelae of stroke, and have better rehabilitation outcomes and quality of life.

Improving Awareness for Spatial Neglect With tDCS

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

Brain-damaged patients can show severe neurological and cognitive deficits, and yet often remain strikingly unaware of these symptoms: this condition is called anosognosia. The aim of this study is to improve awareness in right-brain-damaged patients with Unilateral Spatial Neglect (USN) following stroke using transcranial direct current stimulation (tDCS). tDCS is a neuromodulatory technique that delivers low-intensity current to the brain facilitating (anodal tDCS) or inhibiting (cathodal tDCS) spontaneous neuronal activity. tDCS does not induce activity in resting neuronal networks, but modulates spontaneous neuronal activity: consequently, the amount and direction of effects critically depend on the previous state of the neural structures. We will test USN patients showing anosognosia for neglect symptoms. Different brain areas will be stimulated, to target explicit and implicit components of anosognosia, including parietal and frontal brain regions.
