This randomized controlled trial investigated the effects of neurofeedback targeting somatosensory alpha oscillations on pain modulation in 80 healthy participants experiencing capsaicin-induced pain. Results indicated that real neurofeedback led to higher alpha-power and reduced pain unpleasantness early on, while pain intensity decreased later. The study highlights distinct neurocognitive pathways involved in these effects.
Key findings
- Real neurofeedback resulted in higher α-power over the targeted somatosensory cortex compared to sham feedback.
- Pain unpleasantness showed an early and sustained reduction with real neurofeedback.
- Pain intensity exhibited a later-emerging, block-specific decrease with real neurofeedback.
- Mediation analyses revealed two pathways linking α modulation to pain outcomes.
Why it matters
Understanding the mechanisms of pain modulation through neurofeedback could provide clinicians with innovative, nonpharmacological strategies for managing pain, particularly in patients who may not respond well to traditional analgesics.
