Analysis of Brain Responses and Habituation to Multimodal Sensory Stimuli in Patients With Fibromyalgia

National Council of Scientific and Technical Research, Argentina·observational·Posted Apr 1, 2025·Updated Aug 14, 2025

In Brief

An observational study evaluating Auditory Stimulation, Visual Stimulation, and 5 other interventions for Fibromyalgia. Completed, enrolled 26 participants across 1 site.

Detailed 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.

Interventions

Auditory Stimulationother

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

Visual Stimulationother

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

Somatosensory Stimulationother

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

Auditory-Visual Stimulationother

Stimulation using auditory and visual stimuli concomitantly

Visual-Somatosensory Stimulationother

Stimulation using visual and somatosensory stimuli concomitantly

Auditory-Somatonsensory Stimulationother

Stimulation using auditory and somatosensory stimuli concomitantly

Auditory-Visual-Somatosensory Stimulationother

Stimulation using auditory, visual and somatosensory stimuli concomitantly
