Experimental
pcTBS
10HZ rTMS
The protocol is same as the previous study: pcTBS was administered to the left M1 at 80% resting motor threshold (RMT), consisting of a burst of 3 pulses given at 50 Hz repeated every 5 Hz using repetitive transcranial magnetic stimulation device . A total of 1,200 pulses were delivered with the TMS coil positioned in a posterior-anterior (PA) direction parallel to the midline.
The protocol is same as the previous study: 10HZ rTMS included 15 trains of 10-second stimulation given at 10 Hz to the left M1 at 80% resting motor threshold (RMT) using repetitive transcranial magnetic stimulation device , with the inter-train interval being set to 50 seconds (1500 pulses)
