Study of Sequentially Applied Repetitive Transcranial Magnetic Stimulation in Obsessive- Compulsive Disorders

"For the active group, rTMS over the right prefrontal cortex and the SMA was sequentially performed. The rTMS of the right dorsolateral prefrontal cortex was conducted at a point 5 cm anterior to the point at which the MT was determined, and it was administered at an intensity of 110% of the RMT, a frequency of 1 Hz, for 10 minutes, and with an inter-train interval of 2 minutes (1200 stimuli/d).~The vertex (Cz) was measured for each patient, and the SMA was defined at 15% of the distance between the inion and nasion anterior to Cz on the sagittal midline, according to the international 10-20 EEG system. The rTMS over the SMA was administered at an intensity of 100% of the RMT, a frequency of 1 Hz, for 10 minutes and with an inter-train interval of 2 minutes (1200 stimuli/d).~For the sham group, the sham stimulation was applied with the coil angled at 45° from the scalp using the same parameters as the active stimulation group over the same area."
