Summary

The goal of this clinical trials is to investigate the effectiveness of individualized online repetitive transcranial magnetic stimulation (rTMS) in enhancing upper limb motor rehabilitation during the subacute and chronic phase of stroke. It will also learn about the safety of online rTMS intervention methods. The main questions it aims to answer are: 1. Does individualized rTMS precise target combined with motor training improve upper limb motor rehabilitation in patients？ 2. Does individualized rTMS precise target combined with motor training enhance the upper limb motor rehabilitation ability in stroke patients by strengthening the functional coupling of the motor circuit to achieve functional reorganization of the brain network ? Researchers will compare individualized online rTMS to non-individualized online and individualized sham stimulation in stroke patients to see if individualized online rTMS works to alleviate motor dysfunction in this randomized，sham-controlled, double-blind trial. Participants will: 1. randomized to one group(individualized online, non-individualized online or sham); 2. receive rTMS treatment for 10 days, with 5 working days per week for a total of two weeks; 3. receive magnetic resonance imaging (MRI) and electroencephalogram (EEG) evaluations before and after the entire treatment; 4. conduct scales and MEP assessment one day before the treatment, as well as one day, one month, and three months after the treatment.

Interventions

Type	Name	Description
DEVICE	Individualized online stimulation	The individualized online stimulation group will calculate precise targets based on the collected multimodal MRI (structural images, resting-state/task-state functional images, and diffusion tensor imaging), plan the coil position and placement angle of TMS through electric field simulation, and achieve individualized intervention. At the same time, when patients receive TMS treatment, they are matched with specific upper limb motor tasks. When the task starts autonomously, TMS stimulation is triggered by acceleration-EMG feedback. When the task stops or is completed, TMS stimulation also stops immediately according to the acceleration-EMG feedback to achieve real-time effects.
DEVICE	Non-individualized online stimulation	In the non-individualized online stimulation group, patients receive TMS treatment synchronized with task training. However, the targeting uses traditional positioning methods, i.e., determining the target with a positioning cap instead of precise target localization.
DEVICE	Sham stimulation	In the individualized online sham stimulation group, patients receive TMS treatment combined with specific tasks. The stimulation targets are the same as those in the online stimulation group, all determined by precise target localization, except that a sham stimulation coil is used for TMS stimulation.
