The Efficacy of Temporal Interference Stimulation in the Treatment of Obsessive-Compulsive Disorder

"The TI stimulation device (nerviox-1000) delivers temporally interfering electrical fields with a 130 Hz envelope frequency, generated by high-frequency carrier waves. The stimulation is applied for 20 minutes per session, with a peak current of 3-4 mA per channel, adjusted based on individual tolerance. The stimulation targets include the nucleus accumbens, bed nucleus of the stria terminalis, amygdala, caudate nucleus, and putamen. Stimulation is administered twice daily, with each treatment phase lasting 7 consecutive days.~Sham stimulation uses identical electrode placement and setup as active stimulation. A brief 30-second ramp-up is applied to mimic real stimulation, followed by rapid reduction to 0 mA or minimal current. A 1 mA tail current is delivered in the final 30 seconds to simulate the tapering effect of active stimulation."
