Theta burst stimulation (TBS) is a form of patterned TMS which makes it possible to induce strong and long-lasting effects using lower stimulation intensity and a shorter time of stimulation compared to standard TMS protocols. TBS uses a faster frequency (50Hz instead of 10Hz). It also requires less session time compared to rTMS protocols. Where rTMS takes 30 minutes per session, TBS is dramatically reduced to 3 minute intervals. This creates a more comfortable treatment experience for patients. A full TBS course takes 20 visits while rTMS takes 30 visits.
