Trigeminal Nerve Stimulation (TNS) in the Treatment of Fibromyalgia

Trigeminal Nerve Stimulation (TNS) as a Complementary Strategy in the Treatment of Fibromyalgia, Open Label Study

To the investigators knowledge there are no studies of Trigeminal Nerve Stimulation (TNS) for fibromyalgia. TNS may modify overlapping mood and fibromyalgia pain regulation circuitry. The investigators hypothesized that patients with fibromyalgia might experience a clinically significant reduction in daily pain if investigators were to administer TNS in a manner similar to experimental antidepressant protocols.

Inclusion Criteria:

• We will adopt the following inclusion criteria: (1) patients between 18 and 69 years; (2) patients with a diagnosis of fibromyalgia according to a trained phisycian; (3) score greater than or equal to 5 on the VAS for pain; (4) agreement to participate in the study as recommended in the IC.

Exclusion Criteria:

• Exclusion criteria we cite: (1) patients with psychiatric hospitalization indicated; (2) patients with psychiatric comorbidity; (3) patients with a diagnosis of personality disorder; (4) presence of severe neurological or medical diseases such as neoplasms in activity, neurodegenerative diseases and chronic decompensated.
