LNM-navigated cTBSSham cTBS

LNM-navigated cTBS: Individualized treatment targets are defined by outlining lesion areas on each patient's MRI and projecting them onto a normative functional connectivity map to identify symptom-specific connectivity disruptions within sensorimotor regions. Twice-daily treatments, administered over seven consecutive days, employ an "8"-shaped coil guided by neuronavigation for real-time targeting. For each target, a 40-second session delivers 600 pulses at an intensity of 80% of each participant's resting motor threshold (RMT), administered as 3-pulse bursts at 50 Hz, repeated at a theta frequency of 5 Hz.

Sham cTBS: Sham LNM-navigated cTBS follows the identical workflow, including MRI-based lesion mapping, target selection, electric-field modeling, and neuronavigation, but uses a sham figure-8 coil that mimics the sound and sensation of stimulation without generating a significant magnetic field. Participants receive two sham treatment sessions per day for seven consecutive days. Each session follows the same 40-second protocol timing and coil positioning as the active intervention, ensuring that participants and assessors remain blinded while no effective pulses are delivered.

Study summary

This Phase 2b study will evaluate whether lesion network mapping-guided continuous theta burst stimulation (cTBS) can improve recovery after acute ischemic stroke. The treatment uses each participant's brain imaging to identify individualized stimulation targets related to stroke symptoms. Participants will receive either active cTBS or a sham procedure in addition to standard stroke care. The study will assess the efficacy and safety of this personalized brain stimulation approach and support planning for future confirmatory trials.

Inclusion Criteria: 1. Age 18-80 years. 2. Ischemic stroke onset within the past 14 days. 3. Unilateral, supratentorial ischemic stroke confirmed by CT or MRI. 4. Pre-stroke modified Rankin Scale (mRS) score of 0-1. 5. NIH Stroke Scale (NIHSS) total score 6-25, with item 1a ≤ 1 point, and at least one of items 5a, 5b, 6a, or 6b ≥ 2 points. 6. Written informed consent signed by the patient or the patient's legally authorized representative. Exclusion Criteria: 1. Contraindications to TMS (e.g. cranial metallic foreign bodies, cardiac pacemaker, implanted drug pump, cochlear implant). 2. History of epilepsy or seizure, intracranial hypertension, tumor, or other serious neurological disease. 3. Midline shift or parenchymal mass effect on cranial CT or other imaging. 4. CT or MRI evidence of bilateral acute cerebral infarction or infratentorial acute infarction (brainstem or cerebellum). 5. Evidence of acute intracranial hemorrhage, including spontaneous intracerebral hemorrhage, epidural hematoma, subdural hematoma, intraventricular hemorrhage, or subarachnoid hemorrhage. 6. Pre-stroke mRS ≥ 2. 7. Systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 110 mmHg despite antihypertensive treatment. 8. Pregnant or breastfeeding women, or women planning pregnancy within 90 days. 9. Severe psychiatric disorders or dementia (or other conditions) precluding informed consent or follow-up. 10. Concomitant malignant tumor or severe systemic disease with life expectancy \< 90 days. 11. Participation in any other interventional clinical study within 30 days before randomization, or currently enrolled in such a study.
