Transcranial Magnetic Stimulation

TMS for Complex Regional Pain Syndrome (CRPS)

About the Study

Stanford Systems and Neuroscience Pain Laboratory (SNAPL) has just launched a new study to test if Transcranial Magnetic Stimulation (TMS), a non-invasive brain stimulation technique, can reduce pain related to Complex Regional Pain Syndrome (CRPS) or Reflex Sympathetic Dystrophy (RSD).

TMS is FDA-approved to treat depression and is currently being researched for various other conditions. There is evidence to suggest that TMS can effectively treat certain types of pain and mood disorders. TMS uses a treatment coil placed over the head to administer brief magnetic pulses to a specific location to produce changes in the activity of neurons.

The duration of the study lasts up to 20 weeks and involves four in-person visits to the Stanford Pain Management Center in Redwood City, CA, in addition to weekly electronic questionnaires. Study procedures and TMS treatment are at no cost and participants will receive compensation for their time.


Any person with CRPS or RSD is eligible to participate in the treatment study, provided they:

  • Are between the ages of 18 and 70.
  • Are not pregnant or planning to become pregnant.
  • Have had CRPS for at least 6 months.
  • Have upper and/or lower extremity CRPS.
  • Have been on stable treatment for 3 months.
  • Have no history of epilepsy or seizures.
  • Have no history of Neurologic illness or head injury.
  • Have no metal devices, implants, or shrapnel near the head.
