Transcranial Magnetic Stimulation (TMS) for Trigeminal Neuralgia
- Conditions
- Facial Pain
- Interventions
- Device: TMSDevice: sham TMS coil
- Registration Number
- NCT04120129
- Lead Sponsor
- Carilion Clinic
- Brief Summary
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.
- Detailed Description
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.

- Primary Outcome Measures
Name Time Method Changed Pain assessed by self reported measures: Short-form McGill Pain Questionnaire 2 (SF-MPQ-2) 7 months The primary objective is to establish the effectiveness of 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 received TMS at several timepoints. Short-form McGill Pain Questionnaire 2 (SF-MPQ-2)will be used. The scale asks participants to identify their pain level across body areas and total from 0-10 (0 being none \& 10 worst possible)
- Secondary Outcome Measures
Name Time Method Length of altered pain 7 months A secondary objective is to establish how long the effects of TMS last. This will be done by comparing self-reported pain scores prior to TMS, after TMS and at several timepoints thereafter in those who recieved the treatment. Short-form McGill Pain Questionnaire 2 (SF-MPQ-2) will be used. The scale asks participants to identify their pain level across body areas and total from 0-10 (0 being none \& 10 worst possible)
