About this trial
Transcranial focused ultrasound (tFUS) can be used as a non-invasive brain neuromodulation technique. Low-intensity focused ultrasound has been demonstrated to be safe and have neuromodulatory effects on the cerebral cortex in healthy human and animal experiments.This study aims to investigate the effect of tFUS on cortical excitability for motor recovery in patients with stroke.
Eligibility criteria

No previous history of stroke, epilepsy, dementia, Parkinson's disease, or other neurodegenerative diseases.
Disqualifiers
History of recurrent stroke, traumatic brain injuries, brain tumors, spinal cord injury, Parkinson's disease or other musculoskeletal system diseases that may affect evaluation and treatment.
Contraindications to focused ultrasound, including pregnancy, cardiac pacemaker or implantable medical device, abnormal connective tissue diseases, coagulopathy (PLT<100,000/μL, PT>14 seconds, APTT>36 seconds, INR>1.3), implants near or in the brain, or those deemed Unsuitable for this treatment by the physician.
Unable to cooperate with treatment or functional assessment due to impaired consciousness or aphasia; inability to informed consent.
