NORA-HOME: An Ambulatory Multimodal Monitoring Model In Patients With Minor Stroke And Transient Ischemic Attacks

In this project, we aim to validate a Home Hospitalization plan for patients with TIA or minor stroke. Our hypothesis is that our Multimodal Home Hospitalization program (NORAHOME) for patients with TIA and minor stroke is safe, reduces the complications associated with conventional hospitalization, and is more efficient than Standard Clinical Practice. To conduct the study, we require the voluntary participation of patients with TIA and minor strokes.

Early Functional Proprioceptive Stimulation Post-stroke

The main objective of our study is to evaluate the impact of the use of Functional Proprioceptive Stimulation (FPS) on the recovery of the postural and motor functional capacities of the patient in the subacute phase of a stroke. The hypothesis is that the use of FPS has a positive impact on the recovery of the patient's functional abilities, as well as on the duration of treatment until the sit/stand transfers are completed. To evaluate this potential effect,there will be a randomization with two groups : one will have 5 sessions a week for 6 weeks maximum of SPF and the other groupe will have the same sessions but with the device stettled but not activated.

Mirror Therapy on Motor Recovery and Pain of Hemiparetic Arm

evaluate the effect of mirror therapy on motor recovery and pain of hemiparetic arm post stroke

Trunk Impairment Scale - Adaptation and Validation in French

The objective of this project is to verify the validity and determine the clinimetric properties after translation and adaptation into French of the Trunk Impairment Scale (TIS), a scale for measuring trunk control and seated balance.

Efficacy of a Telehealth Delivered Group Lifestyle Balance for People Post Stroke (tGLB-CVA)

Investigators will conduct a randomized controlled trial (RCT) to assess intervention efficacy of telehealth delivery of the GLB-CVA (tGLB-CVA) compared to a 6-month wait-list control (WLC) in partnership with a diverse group of patient partners and peer mentors.

Study on the Safety and Effectiveness of a Biodegradable Patent Foramen Ovale Occluder System

To evaluate the Safety and Efficacy of a Novel Biodegradable Occluder for Percutaneous Closure of Patent Foramen Ovale (PFO)

[18F]AlF-NOTA-octreotide PET/MRI in Carotid Artery Disease

This clinical trial aims to evaluate whether \[¹⁸F\]AlF-OC PET/MRI can characterize and quantify inflammation in carotid atherosclerotic plaques. The study will assess if tracer uptake in culprit and non-culprit carotid arteries, measured by standardized uptake values (SUV), is associated with future cerebrovascular events. Specifically, it will examine whether \[¹⁸F\]AlF-OC uptake predicts the risk of recurrent ipsilateral TIA, amaurosis fugax, stroke, or other vascular complications. Participants will undergo \[¹⁸F\]AlF-OC PET/MRI and will be followed via telephone interviews at 90 days, 1 year, and 3 years after their initial stroke or TIA.

Characterising the Neuromuscular Function of Post Stroke Patients

Strokes are a leading cause of death and disability in developed countries, with significant economic and social impacts. Defined by the WHO, strokes cause rapid and lasting disturbances in cerebral function. In the UK, strokes occur every five minutes, affecting 100,000 people annually and resulting in substantial physical impairments and financial costs. Although stroke-related deaths have decreased due to improved treatments and awareness, strokes remain a major cause of death and disability worldwide, especially in lower-income countries. Strokes typically cause unilateral deficits, leading to significant daily challenges and necessitating tailored rehabilitation strategies such as CIMT, FES, and VR Rehab. As the population ages, innovative neurorehabilitation approaches are essential to enhance functional recovery post-stroke. This pilot study aims to better understand the neuromuscular deficits caused by stroke to inform and improve future rehabilitation interventions, including the potential use of force accuracy training (FAT)

Emergency Stroke Unit for Acute Cerebrovascular Events: A Prospective, Single-arm Trial With a Historical Control Group

Background Reperfusion therapies, i.e., intravenous thrombolysis (IVT) and/or endovascular thrombectomy (EVT), are most effective treatments in the management of acute ischemic stroke (AIS) patients. The benefits of reperfusion therapies, however, may be reduced by treatment delays due to tests and examinations and logistic issues. Emergency Stroke Unit (ESU), a new concept of stroke unit locating at the Accident and Emergency Department (AED), equipped with a mobile, low-field MR imaging (lfMRI) scanner for fast diagnosis of ischemic stroke, differentiation of intracranial hemorrhage and identification of large vessel occlusion (LVO), is being tested in Mainland China. It may shorten the door-to-needle time (DNT) for IVT and door-to-groin puncture time (DPT) for EVT, which may hance associate with improved functional outcomes of AIS patients. This is a prospective, single-center, open-label, non-randomized, single-arm study aims to evaluate the safety and efficacy of the ESU workflow using lfMRI in shortening the DNT/DPT and improving functional outcomes in AIS patients, who are potentially eligible for IVT and/or EVT and can be treated within 6 hours after onset, compared with standard practice in Hong Kong; to reveal the changes in the ischemic lesions over a few days after IVT/EVT in these patients, with serial follow-up lfMRI exams.

The Imperial Comprehensive Cognitive Assessment in Cerebrovascular Disease (IC3)

Stroke is a major cause of death and disability worldwide, frequently resulting in persistent cognitive deficits among survivors. These deficits negatively impact recovery and therapy engagement, and their treatment is consistently rated as high priority by stakeholders and clinicians. Although clinical guidelines endorse cognitive screening for post-stroke management, there is currently no gold standard approach for identifying cognitive deficits after stroke, and clinical stroke services lack the capacity for long-term cognitive monitoring and care. Currently available assessment tools are either not stroke-specific, not in-depth or lack scalability, leading to heterogeneity in patient assessments. To address these challenges, a cost-effective, scalable, and comprehensive screening tool is needed to provide a stroke-specific assessment of cognition. The current study presents such a novel digital tool, the Imperial Comprehensive Cognitive Assessment in Cerebrovascular Disease (IC3), designed to detect both domain-general and domain-specific cognitive deficits in patients after stroke with minimal input from a health professional. To ensure its reliability, we will utilise multiple validation approaches, and aim to recruit a large normative sample of age-, gender-, and education-matched UK-based controls. Moreover, the IC3 assessment will be integrated within a larger prospective observational longitudinal clinical trial, where post-stroke cognition will be examined in tandem with brain imaging and blood biomarkers to identify novel multimodal biomarkers of recovery after stroke. By leveraging this rich dataset, our study will allow more precise targeting of cognitive rehabilitation to stroke survivors that are most at risk of progressive cognitive decline and have the greatest potential for recovery.
