| Transcranial Magnetic Stimulation for Treating Women With Chronic Widespread Pain |
| Transcranial Magnetic Stimulation (TMS) in the Treatment of Chronic Widespread Pain (CWP) |
While acute pain after surgery or trauma comes on suddenly and lasts for a limited amount of time, chronic pain persists and can continue for months and even years. Repetitive transcranial magnetic stimulation (rTMS) uses a magnetic field to deliver a current to the brain and can affect brain activity. The purpose of this study is to determine the effectiveness of rTMS treatment in reducing chronic widespread pain in women. |
Chronic widespread pain is characterized by musculoskeletal pain that lasts for at least 3 months, pain above and below the waist, pain on both the right and left sides, and pain in the head, neck, spine, or back. In addition to fatigue, chronic widespread pain is a hallmark feature of fibromyalgia. Significant physical and emotional effects usually accompany chronic widespread pain and fibromyalgia, making the development of effective treatments a priority. rTMS involves a neurophysiologic technique that directs a current into the brain by using a magnetic field to pass the scalp and skull safely and painlessly. Stimuli are applied to the same brain area several times per second during several consecutive seconds. rTMS has been found to be effective for treating certain types of chronic pain. The purpose of this study is to determine the effectiveness of rTMS treatment in reducing bodily pain associated with chronic widespread pain and/or fibromyalgia in women.
Participants in this study will undergo a diagnostic interview, physical and neurological exam, electrocardiogram, magnetic resonance imaging, and blood and urine collection for screening purposes. Eligible participants will then be randomly assigned to receive either rTMS treatment or sham rTMS treatment. One-hour daily treatment sessions will occur over 15 days. After every five treatment sessions, participants will be interviewed about their pain and depression symptoms, and they will fill out questionnaires about pain, depression, fatigue, sleep, and exercise. Participants will also undergo pain threshold and tolerance testing of their right thumb. On a daily basis, participants will rate their level of pain using a 0 to 20 scale. Follow-up evaluations will occur 1, 4, and 12 weeks after treatment and will include a repeat interview and testing. After the follow-up evaluations, any participants who did not respond to the sham treatment will be offered a series of 15 real rTMS treatment sessions. |

Inclusion Criteria:
- Diagnosis of chronic widespread pain as defined by the 1990 American College of Rheumatology guidelines: chronic musculoskeletal pain for at least 3 months; pain above and below the waist; pain on both right and left sides; pain at one axial site (e.g., head, neck, spine, or back)
- Willing to remain on a stable medical regimen during the entire 6-week course of Phase 1 treatment and 8 weeks prior to rTMS treatment
- Willing to undergo random assignment and able to attend treatment sessions
- Willing to remain on a stable psychotherapy regimen if currently receiving psychotherapy that has been ongoing for at least 3 months prior to study entry
Exclusion Criteria:
- Unable to maintain treatment as usual at stable doses for any medical or psychiatric conditions for 8 weeks prior to and during the study
- Another medical condition associated with significant pain (e.g., diabetic neuropathy, systemic lupus erythematosus, Rheumatoid arthritis, severe degenerative joint disease)
- Any condition that might increase the risk of seizures from TMS
- History of a seizure disorder or family history of a seizure disorder
- Previous use of TMS
- Involvement in litigation or disability that is related to fibromyalgia, chronic widespread pain, or depression
