Habituation of Brain Responses to Sensory Stimuli in Fibromyalgia

NCT06905171 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 26

Last updated 2025-08-14

No results posted yet for this study

Summary

The goal of this observational study is to assess event-related potentials and habituation in patients with fibromyalgia. The main research questions are:

* Is there a measurable difference in sensory responses between fibromyalgia patients and healthy control?
* Could these measures provide evidence supporting claims of hypersensitivity?

Participants will:

\- receive randomized sensory stimuli (auditory, visual, somatosensory, audiovisual, auditory-somatosensory, visual-somatosensory, and auditory-visual-somatosensory) in blocks of 20 trials.

Conditions

  • Fibromyalgia

Interventions

OTHER

Auditory Stimulation

A tone at a 1000 Hz frequency, delivered through speakers at a comfortable volume

OTHER

Visual Stimulation

A checkerboard pattern displayed on a monitor, with colors alternating every 25 ms

OTHER

Somatosensory Stimulation

A train of three electrical stimuli, each lasting 1 ms, separated by 8 ms, at an intensity that clearly elicits a pricking sensation

OTHER

Auditory-Visual Stimulation

Stimulation using auditory and visual stimuli concomitantly

OTHER

Visual-Somatosensory Stimulation

Stimulation using visual and somatosensory stimuli concomitantly

OTHER

Auditory-Somatonsensory Stimulation

Stimulation using auditory and somatosensory stimuli concomitantly

OTHER

Auditory-Visual-Somatosensory Stimulation

Stimulation using auditory, visual and somatosensory stimuli concomitantly
