As above mentioned, the transcranial electrical stimulation (<sub>e</sub>TCS) of both trigeminal roots induced a neuromuscular response called “bilateral Root-Motor-Evoked Potential” ( R-MEPs). It was performed by an electromyographic device (Nemus -NGF, EBNeuro, Firenze, Italy).<ref>Frisardi G (1992) The use of transcranial stimulation in the fabrication of an occlusal splint.

Considering the safety limitations,<ref>IEC60601-2-40 (1998) Medical electrical equipment: Particular requirements for the safety of electromyographs and evoked response equipment.</ref> we computed the energy delivered for each single pulse in our application through this formula: <math>E=P\cdot\Delta T=R\cdot I^2\cdot \Delta T=2.5 mJ</math> per pulse. Since 2 stimulators were used, the limits were ten times lower than those stated in the IEC regulation. | Considering the safety limitations,<ref>IEC60601-2-40 (1998) Medical electrical equipment: Particular requirements for the safety of electromyographs and evoked response equipment.</ref> we computed the energy delivered for each single pulse in our application through this formula: <math>E=P\cdot\Delta T=R\cdot I^2\cdot \Delta T=2.5 mJ</math> per pulse.
