Analysis of Brain Responses and Habituation to Multimodal Sensory Stimuli in Patients With Fibromyalgia
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
A tone at a 1000 Hz frequency, delivered through speakers at a comfortable volume
A checkerboard pattern displayed on a monitor, with colors alternating every 25 ms
A train of three electrical stimuli, each lasting 1 ms, separated by 8 ms, at an intensity that clearly elicits a pricking sensation
Stimulation using auditory and visual stimuli concomitantly
Stimulation using visual and somatosensory stimuli concomitantly
Stimulation using auditory and somatosensory stimuli concomitantly
Stimulation using auditory, visual and somatosensory stimuli concomitantly
