Safety Standards
  • Rossi et al., 2009: Train duration limits by frequency and intensity
  • Rossi et al., 2021: Updated safety recommendations
  • IFCN Guidelines: International standard for TMS safety
Key Calculation Rules
  • Pulses per train = Frequency (Hz) × Train duration (s)
  • Total session time = (Trains × Duration) + (Trains-1) × ITI
  • Total pulses = Pulses per train × Number of trains
  • Weekly load = Total pulses × Sessions per week
