Non-Invasive Deep Brain Stimulation for Upper Limb Recovery After Stroke (NIMBUS)

NIMBUS is a clinical study evaluating a new, non-invasive brain stimulation treatment to improve arm and hand function in people with long-term effects of stroke. The treatment uses a personalized method to stimulate deeper areas of the brain through the scalp, without surgery, while participants undergo intensive physiotherapy rehabilitation. Physiotherapy in combination with the brain stimulation will occur three times a day over the course of a week. In the study, participants are randomly assigned to receive either the active treatment or a sham (inactive) version, so researchers can compare the outcomes fairly. The study will assess whether the treatment is safe, feasible, and effective by measuring changes in arm movement, daily activities, and brain function before and after the treatment. The goal is to determine whether this approach can enhance recovery after stroke and support the development of improved rehabilitation therapies.

Artificial Intelligence-Assisted Magnetic Resonance Imaging Diagnostic Strategy in a Tertiary Stroke Center

Quality improvement study with prospective observational design. The study monitors the diagnostic accuracy of an AI-assisted resident radiologist-termed the AI-ResRad diagnostic strategy-compared to an on-call specialist neuroradiologist-termed the SpecNeuroRad strategy-in interpreting stroke MRIs in patients with known onset. The study includes a pre-planned sub-study evaluating the diagnostic accuracy of neurologists and AI-assisted neurologists.

Effect of E-learning Training on National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (mRS) Assessment

The goal of this web-based randomized clinical trial is to evaluate whether an e-learning training program improves the accuracy of National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) assessments among practicing paramedics in French-speaking Switzerland who have not previously received formal training in these scales. The main questions it aims to answer are: * Does e-learning training improve performance on a standardized NIHSS assessment quiz compared with no prior training? * Does e-learning training improve the accuracy of mRS assessment using case-based clinical vignettes compared with no prior training? Researchers will compare paramedics who complete the NIHSS and mRS e-learning modules before assessment (intervention group) with paramedics who complete the assessments without prior training (control group) to determine whether e-learning training leads to higher assessment performance scores. Participants will: * Provide electronic informed consent via a secure web-based platform * Be randomly assigned to either the intervention group or the control group * Complete either the e-learning modules before assessment or the assessments before training, depending on group allocation * Complete an online NIHSS quiz and mRS case-based vignettes * Receive access to the NIHSS and mRS e-learning modules by the end of the study
