Detaillierte Beschreibung
Acute ischemic stroke often leads to persistent motor impairment despite standard medical treatment and rehabilitation. The early post-stroke period may represent an important window for modulating brain network plasticity and promoting recovery. Continuous theta burst stimulation (cTBS), a patterned form of repetitive transcranial magnetic stimulation, can modulate cortical excitability over a short stimulation period and may support recovery when applied to clinically relevant motor networks.
This study evaluates a personalized neuromodulation approach based on lesion network mapping. For each participant, the acute infarct lesion is identified on clinical brain imaging and mapped to a reference functional connectome to estimate lesion-associated networks. Candidate stimulation targets are selected from symptom-relevant cortical network nodes, with consideration of accessibility, safety, and electric-field modeling. Neuronavigation is used to guide coil placement and maintain targeting accuracy.
Active treatment consists of lesion network mapping-guided cTBS delivered to individualized cortical targets using a figure-8 coil under neuronavigation. Sham stimulation follows the same imaging-based target selection, electric-field modeling, positioning, and procedural workflow, but uses a sham coil designed to mimic the sensory and acoustic features of stimulation without delivering a therapeutic magnetic field. This approach is intended to maintain blinding while isolating the effect of active stimulation.
This Phase 3 trial evaluates the efficacy and safety of individualized lesion network mapping-guided cTBS for recovery after acute ischemic stroke.

Intervention / Behandlung |
|---|---|
|
Experimental: LNM-navigated cTBS group
Participants receive active lesion network mapping (LNM)-navigated continuous theta burst stimulation (cTBS).
|
Individualized treatment targets are defined by outlining each patient's acute infarct lesion on MRI and projecting it onto a normative functional connectivity map to identify symptom-relevant network nodes within sensorimotor regions.
Treatment is delivered over seven consecutive days using a figure-8 coil guided by neuronavigation.
cTBS consists of 3-pulse bursts at 50 Hz, repeated at 5 Hz, for a total of 600 pulses over 40 seconds, delivered at 80% of the resting motor threshold (RMT).
|
|
Schein-Komparator: Sham cTBS group
Participants receive sham LNM-navigated cTBS using procedures that mimic the active intervention.
|
Sham stimulation follows the same MRI-based lesion mapping, target selection, neuronavigation workflow, coil positioning, timing, acoustic noise, and treatment course as the active group, but uses a sham figure-8 coil that mimics stimulation without generating a significant magnetic field.
This design helps maintain blinding of participants and assessors while ensuring that no effective magnetic stimulation is delivered.
