Single-Center, Double-Blind, Randomized, Placebo-Controlled Study on Efficacy and Safety of rTMS (With Precise Localization) in Relieving Motor Symptoms of TD

"Patients will receive rTMS treatment for a total of 14 days. Prior to treatment, patients will undergo an MRI scan; the images will be preprocessed to construct a structural network, and precise localization of the pre-SMA (preSupplementary Motor Area) region and the SCAN (Somatosensory-Cognitive-Action Network) will be performed based on coordinates.~Participants will receive two treatment sessions per day, with an interval of at least 1 hour between each session. Each treatment session consists of 3 cTBS (Continuous theta-Burst Stimulation) treatments, and the interval between each cTBS treatment is at least 15 minutes. Each cTBS treatment lasts 40 seconds, comprising 3 pulses at 50 Hz, repeated every 200 ms (equivalent to 5 Hz), totaling 600 pulses per cTBS treatment. Accordingly, patients receive a total of 3,600 pulses per day, and a cumulative total of 50,400 pulses are delivered throughout the entire treatment period."
