Outcome Measures

Primary Outcomes (2)

  • 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

    3 weeks

  • 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

    3 weeks

Secondary Outcomes (3)

  • Functional MRI measures of sensory system activity. A functional MRI signal change scale ranging from 0 to 1 will be used.

    3 weeks

  • Measured fibromyalgia symptoms using a 101-point numerical rating scale.

    3 weeks

  • Tolerability rated using a numerical rating scale ranging from 0 to 100 points.

    3 weeks

Study Arms (2)

Actual treatment

EXPERIMENTAL

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).

Device: Vibrotactile stimulation

Sham

SHAM COMPARATOR

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

Device: Vibrotactile stimulation

Interventions

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.
