Figure 1. Typical stimulus parameters used in four repetitive transcranial magnetic stimulation protocols.

Figure 1

A, regular high frequency repetitive transcranial magnetic stimulation (rTMS) at 10 Hz. Interstimulus interval (ISI) is 100 ms. Stimulus intensity, number of pulses per train and inter-train intervals (ITIs) are limited for safety reasons. B, continuous theta burst stimulation (cTBS). Trains of pulses (600 pulses) are delivered in a continuous pattern with ITI of 200 ms (5 Hz). The bottom frame magnifies one train of stimuli. Each train consists of three pulses with ISI of 20 ms (50 Hz). Stimulus intensity is set at 80% active motor threshold (AMT). C, intermittent theta burst stimulation (iTBS). Trains of pulses (600 pulses) are delivered in an intermittent pattern with inter-block interval (IBI) of 10 s (20 blocks in total). The bottom frame magnifies one block of stimuli. Each block consists of 10 trains with ITI of 200 ms (5 Hz). Each train consists of three pulses with ISI of 20 ms (50 Hz). Stimulus intensity is set at 80% AMT. D, quadripulse stimulation at 5 ms ISI (QPS5ms). Trains of pulses (1400 pulses) are delivered in a continuous pattern with ITI of 5 s (0.2 Hz). The bottom frame magnifies one train. Each train consists of four pulses with ISI of 5 ms (200 Hz). Stimulus intensity is set at 90% AMT.
