Measurement reliability is an important aspect of establishing the utility of scores used in clinical practice.
Although much is known about the reliability of quantitative electroencephalographic (qEEG) metrics related to absolute power, less is known about the reliability of coherence metrics. The current study examined the measurement reliability of coherence metrics across standard frequency bands during an eyes-closed resting state. Reliability was examined both within channel pairs, and averaged across
spatially contiguous channels, to summarize global patterns. We found that while most channel pairs were highly reliable on average, there was substantial variability across channels. Finally, w
e estimated the effect of measurement reliability on the detection of treatment-related neural change.
We concluded that estimates of reliability for treated channels are crucial, and should factor into clinical assessment of treatment efficacy for EEG biofeedback (neurofeedback), especially in cases where large cross-channel variability is present.

Fibromyalgia syndrome (FMS) is a chronic rheumatological condition which could be characterized by generalized pain and fatigue. Cognitive and behavioral therapy has been found to be a suitable technique in the management of FMS. This study intends to evaluate the efficacy of electromyography (EMG) biofeedback to reduce pain in patients with FMS.
MATERIALS AND METHODS:
A randomized controlled trial involving two groups of FMS patients, one receiving EMG biofeedback and the other a sham biofeedback, was carried out. The assessment tools included in the study were fibromyalgia impact questionnaire (FIQ), visual analogue scale (VAS), six-minute walk test (SMWT) and number of tender points; and tenderness of each tender point was done for both the groups.
A Student's 't' test was used to study the test for significance.
After using biofeedback, the mean VAS scores and the mean number of tender points were found to be 3 out of 10 and 6 out of 18 respectively. Subjective analysis from both groups showed improvement in physical and psychological realms. Statistical significance.
Biofeedback as a treatment modality reduces pain in patients with FMS, along with improvements in FIQ, SMWT and the number of tender points
