About this trial

This is an interventional treatment trial for Fibromyalgia

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)FemaleDoes not accept healthy volunteers

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.

Arm Type

Experimental

Sham Comparator

Arm Label

Actual treatment

Sham

Arm Description

Vibrotactile sensory stimulation will consist on whole-body stimulation with mechanical stimuli of pallesthetic type at high rate (2-90 Hz), low intensity and long daily duration (3h).

Sham treatment will be applied using identical instruments and with power and duration programmed identically. However, in this case, the output will not be the signal activating the vibration motors, but rather an electrical signal turning on an incorporated pilot light indicating that the (simulated) treatment was operating

Outcomes

Primary Outcome Measures

Functional MRI measures of brain functional connectivity. A correlation scale ranging from 0 to 1 will be used.
Change on brain activity rated using functional MRI measures of functional connectivity
Functional MRI measures of brain activity. A functional MRI signal change scale ranging from 0 to 1 will be used.
Change on brain activity rated using functional MRI measures of brain activation in response to nociceptive stimulation

Secondary Outcome Measures

Functional MRI measures of sensory system activity. A functional MRI signal change scale ranging from 0 to 1 will be used.
Change on brain activity rated using functional MRI measures of brain activation in response to non-nociceptive stimulation
Measured fibromyalgia symptoms using a 101-point numerical rating scale.
Change on fibromyalgia symptoms (including pain, fatigue, cognitive symptoms, sleep disturbance, and general health rating). Rated using Numerical Rating 101-point Scales.
Tolerability rated using a numerical rating scale ranging from 0 to 100 points.
Tolerability index (0-100).

Device
Intervention Name(s)
Vibrotactile stimulation
Intervention Description
The active treatment will involve whole-body sensory stimulation with mechanical stimuli of vibrotactile (pallesthetic) type at a relatively high rate, low intensity and long duration administered at sleep time (a total daily duration of 3 h distributed within a period of 2 h at bedtime and 1 h prior to getting up). The intensity will be 30% of power at bedtime and 45% prior to getting up.
