Objective.
The objective of this prospective cross-sectional study was to analyze the differences between patients with fibromyalgia and non-pain controls in terms of EEG power in the eyes-closed resting state.
This study also aims to evaluate potential correlations between EEG power and subjective pain.
Methods.
The fibromyalgia patients were recruited by the Extremadura Association of Fibromyalgia (AFIBROEX) in Cáceres, Spain.
Age- and sex-matched healthy controls (1:1 ratio) were recruited from university facilities and people close to the AFIBROEX by public calls.
All underwent EEG during a 1-minute resting period with their eyes closed.
The theta, alpha-1, alpha-2, beta-1, beta-2, and beta-3 frequency bands were analyzed by using EEGLAB.
Self-reported visual analog scale pain scores were determined just prior to EEG.
Results.
A total of 62 women participated in the study, 31 of them diagnosed with fibromyalgia and 31 healthy controls.
Fibromyalgia group exhibited a significantly lower alpha-2 in C4, T3, P4, Pz, and O2 compared to the healthy controls.
Interestingly, pain correlated negatively with alpha-2 in Cz, P4, and Pz only in the fibromyalgia group.
Conclusion.
The fibromyalgia group exhibited decrease alpha-2 power in central, temporoparietal, and occipital brain areas.
Furthermore, higher values of pain correlated with lower level of alpha-2 power in Cz, P4, and Pz.
These findings may point the importance of alpha-2 power in pain in women with fibromyalgia.
