Background: Fibromyalgia syndrome (FMS), a condition characterized by widespread pain and chronic fatigue, has been suggested to represent a prototype of central nervous system hypersensitivity (central sensitivity-CS) (Cagnie et al., 2014 ) While the mechanisms underlying CS remain incompletely understood, a role for limbic dysregulation has been argue (Neugebauer et al., 2004). The aim of the current study was to examine the feasibility of fMRI-inspired Electrical Finger Print (EFP) of the amygdala as a probe for NeuroFeedback (amyg-EFP NF) training for FM patients. We expected improved pain symptoms and sleep quality among trainees successful in downregulating amygdala activity. Method: 13 patients (1M:12F, average age 32.4 SD=12.1) underwent 10 sessions of amyg-EFP-NF, targeting down-regulating of the amygdala. Two interfaces was used to give the feedback-Auditory feedback and multi-modal virtual realty feedback (see fig.1) Successful sessions were indicated by significantly lower amyg-EFP activity in the feedback condition comparing to rest. Outcome measures included: Sleep quality (objective & subjective measures), pain (clinical evaluation & self-reports) and emotion regulation (questionnaires). Measurements were taken before and after NF training (see fig. 2). Results: Following NF Training, patients displayed an improved clinical status as indicated by reduction in FMS symptoms (FIQ, T=3.081 P=0.004). Improvements in self-reported pain (SF 36, R=0.81, p=0.001), social function (SF 36, R=0.7, p=P=0.007) and physical health (SF 36, R=0.839, p=0.0003) were correlated with measures of amygdala down-regulation (see fig. 4). Affective and anxiety scores (STAI-T, beck depression inventory) remained unchanged. Moreover, patients demonstrated reduced sleep latency (T=2.71, P=0.02) and normalised REM latency (T=1.9, P=0.04). Notably, despite time in bed was reduced (T=3.01, P=0.005), fatigue level was decreased (Stanford sleepiness scale, T=2.7, P=0.009). (See fig. 5.) Discussion: We targeted the amygdala, an emotional hub of the brain, rather than classic parts of the so-called "pain matrix" in order to improve the suffering and overall wellbeing of patients with a chronic pain syndrome. We show that amygdala downregulation improved disease and pain related suffering, sleep latency and sleep architecture in chronic pain patients.
