Impact of Fibromyalgia on Alpha-2 EEG Power Spectrum in the Resting Condition: A Descriptive Correlational Study

Figure 1

Topographic maps of the power spectrum in the alpha-2 (11-12 Hz) frequency band for (a) fibromyalgia group (b), the healthy controls, and (c) the comparison of the fibromyalgia patients and the healthy controls in terms of alpha-2 power at 19 scalp channels. The bars indicate standard deviation of the mean. Significantly higher values (p<0.05) in the healthy controls versus the fibromyalgia group, as determined by independent t-tests.
