Exploring electroencephalographic infraslow neurofeedback treatment for chronic low back pain: a double-blinded safety and feasibility randomized placebo-controlled trial
Chronic low back pain (CLBP) is a disabling condition worldwide. In CLBP, neuroimaging studies demonstrate abnormal activities in cortical areas responsible for pain modulation, emotional, and sensory components of pain experience [i.e., pregenual and dorsal anterior cingulate cortex (pgACC, dACC), and somatosensory cortex (SSC), respectively]. This pilot study, conducted in a university setting, evaluated the feasibility, safety, and acceptability of a novel electroencephalography-based infraslow-neurofeedback (EEG ISF-NF) technique for retraining activities in pgACC, dACC and SSC and explored its effects on pain and disability. Participants with CLBP (n = 60), recruited between July'20 to March'21, received 12 sessions of either: ISF-NF targeting pgACC, dACC + SSC, a ratio of pgACC*2/dACC + SSC, or Placebo-NF. Descriptive statistics demonstrated that ISF-NF training is feasible [recruitment rate (7 participants/month), dropouts (25%; 20-27%), and adherence (80%; 73-88%)], safe (no adverse events reported), and was moderate to highly acceptable [Mean ± SD: 7.8 ± 2.0 (pgACC), 7.5 ± 2.7 (dACC + SCC), 8.2 ± 1.9 (Ratio), and 7.7 ± 1.5 (Placebo)]. ISF-NF targeting pgACC demonstrated the most favourable clinical outcomes, with a higher proportion of participants exhibiting a clinically meaningful reduction in pain severity [53%; MD (95% CI): - 1.9 (- 2.7, - 1.0)], interference [80%; MD (95% CI): - 2.3 (- 3.5, - 1.2)], and disability [73%; MD (95% CI): - 4.5 (- 6.1, - 2.9)] at 1-month follow-up. ISF-NF training is a feasible, safe, and an acceptable treatment approach for CLBP.

BACKGROUND: Neuroscience education therapy (NET) has been successfully used for numerous overlapping pain conditions, but few studies have investigated NET for migraine. OBJECTIVE: We sought to 1) review the literature on NET used for the treatment of various pain conditions to assess how NET has been studied thus far and 2) recommend considerations for future research of NET for the treatment of migraine. DESIGN/METHODS: Following the PRISMA guideline for scoping reviews, co-author (TR), a medical librarian, searched the MEDLINE, PsychInfo, Embase, and Cochrane Central Clinical Trials Registry databases for peer-reviewed articles describing NET to treat migraine and other chronic pain conditions. Each citation was reviewed by two trained independent reviewers. Conflicts were resolved through consensus. RESULTS: Overall, a NET curriculum consists of the following topics: pain does not equate to injury, pain is generated in the brain, perception, genetics, reward systems, fear, brain plasticity, and placebo/nocebo effects. Delivered through individual, group, or a combination of individual and group sessions, NET treatments often incorporate exercise programs and/or components of other evidence-based behavioral treatments. NET has significantly reduced catastrophizing, kinesiophobia, pain intensity, and disability in overlapping pain conditions. In migraine-specific studies, when implemented together with traditional pharmacological treatments, NET has emerged as a promising therapy by reducing migraine days, pain intensity and duration, and acute medication intake. CONCLUSION: NET is an established treatment for pain conditions, and future research should focus on refining NET for migraine, examining delivery modality, dosage, components of other behavioral therapies to integrate, and migraine-specific NET curricula.
