This study aims to evaluate how transcranial focused ultrasound (tFUS) technology can promote neural network remodeling and functional recovery after stroke. By integrating signals from electroencephalography (EEG) and magnetic resonance imaging (MRI), the study will investigate how activating or inhibiting specific brain regions affects motor and cognitive recovery. The goal is to improve patients' motor and cognitive functions, reduce long-term disability, and enhance quality of life. The study also seeks to optimize stimulation parameters to maximize rehabilitation outcomes and explore the mechanisms underlying neuroprotection and functional reconstruction after stroke. This is a case-control study involving a total of 60 participants. Participants will be ischemic stroke survivors aged 18-75 years, with first-ever stroke onset between 21 days and 6 months, stable vital signs, no consciousness disorders, and the ability to provide informed consent and cooperate with assessments. Eligible participants must have unilateral limb motor impairment, with an upper extremity modified Ashworth score ≤3, Brunnstrom stage II-V, and an upper extremity Fugl-Meyer Assessment (FMA-UE) score between 15 and 60. Participants will be assigned to either a neuromodulation group (receiving multi-modal neuromodulation targeting specific brain regions) or a control group (receiving sham stimulation or conventional treatment). Primary outcome measures include changes in FMA-UE scores, neuroimaging data (CT/MRI), EEG measurements (resting-state and task-state spectral power, functional connectivity), and laboratory markers (complete blood count, CRP, IL-6, S100β, BDNF). Secondary outcome measures include Brunnstrom stage, Ashworth grade, muscle strength, and patient comfort ratings. Safety will be monitored through blood routine tests, blood biochemistry, and coagulation function. Statistical analysis will compare key indicator changes between the neuromodulation and control groups before and after intervention. Independent t-tests (for two groups) or ANOVA (for multiple groups) will be used to assess between-group differences, with non-parametric tests applied for data not following a normal distribution.
