Functional MRI Study of Vibrotactile Stimulation Effects in Fibromyalgia

Functional MRI Study of the Effects of Vibrotactile Sensory Stimulation on Brain Activity in Fibromyalgia Patients

The purpose of this study is to investigate the effects of low-intensity and prolonged vibrotactile sensory stimulation on brain activity and functional connectivity in fibromyalgia patients.

Inclusion Criteria:

1. A diagnosis of fibromyalgia according to the American College of Rheumatology (ACR) (Arthritis Care Res 2010;62:600-10).
2. Clinical symptoms are not a consequence of other medical disorder (although the presence of other disorders is not an exclusion criterion)
3. Diagnoses established by an expert on fibromyalgia.
4. Stable treatment of chronic use.
5. Subject demonstrates an understanding of the study and a willingness to participate as evidenced by voluntary written informed consent.

Exclusion Criteria:

1. Generalized inflammatory articular or rheumatic disease.
2. Severe, non-stable medical, endocrinological or neurological disorder.
3. Psychotic disorder or drug abuse.
