Repetitive Transcranial Magnetic Stimulation for Pain Relief

We used MagStim Super Rapid² Plus¹ (Magstim Company Ltd., Whitland, UK) stimulation system and D70 Alpha Flat Coil (Magstim Company Ltd.) of figure-eight coil. The rTMS was applied at 90% motor threshold that stimulation moved the monkeys’ fingers with an approximately one-half possibility. Stimuli were delivered at the pulse frequency of 5 Hz, each pulse train of 10 s, and intertrain interval of 50 s. Trains were repeated 10 times, and finally generated 500 pulse stimulations (see also Supplementary Method). This stimulation parameter is equivalent to that used for patients with CPSP^{41 (link)–45 (link)}. Sham stimulation was performed by tilting the same coil 90 degrees and the coil was also separated (by more than 20 mm) from their heads.
