Transcranial Magnetic Stimulation (TMS) for Trigeminal Neuralgia
Transcranial Magnetic Stimulation (TMS) for Trigeminal Neuralgia
The primary objective is to establish the feasibility of using TMS for COFP pain management
 in the interim period before surgery. This will be investigated by comparing the
 non-intervention group's self-reported pain to those who recieved TMS at several timepoints.
Participants will be randomized to either receive transcranial magnetic stimulation (TMS),
 Sham-TMS (a non-therapeutic TMS coil which sounds and feels similar to normal TMS), or
 standard treatment during the weeks of wait time before surgery for chronic orofacial pain
 (COFP). TMS is a noninvasive, painless magnetic device which, when applied to the head for a
 few minutes, has been shown to reduce pain in people with COFP. The sham TMS is a
 sub-therapeutic level of magnetcic stimulation which makes the same sound as normal TMS and
 causes a similar tingling of the skin.

 Both those who receive this new pain intervention and those who do not will be asked to fill
 out a short online survey about their pain at several points during the study. The survey
 takes about 10 minutes to fill out and each of the 5 TMS sessions last 10 minutes.
