Alpha entrainment drives pain relief using visual stimulation in a sample of chronic pain patients. A proof-of-concept controlled study.

Abstract: One-third of the population in the UK and worldwide struggle with chronic pain. Entraining brain alpha activity through non-invasive visual stimulation has been shown to reduce experimental pain in healthy volunteers. Neural oscillations entrainment offers a potential non-invasive and non-pharmacological intervention for patients with chronic pain, which can be delivered in the home setting and has the potential to reduce use of medications. However, evidence supporting its use in patients with chronic pain is… Show more

“…If clearer epidemiological and neurobiological links emerge, therapies like biofeedback and entrainment, proven effective for chronic pain (111)(112)(113), may play a role in the management of FS. This is vital considering the current absence of treatments that offer universal or long-term control of not only FS, but also FND as a whole.…”

“…Specifically, whilst neural entrainment of alpha frequencies was effective in reducing pain intensity from experimentally-induced acute pain, there was no consistent evidence supporting its use in chronic pain. A recent study 41 published after our search period extended Arendsen et al's 30 study by testing eight additional volunteers, thereby increasing statistical power. This study provided evidence that visual alpha entrainment may reduce pain intensity ratings for those with chronic pain.…”

“…Alpha entrainment has been found to reduce experimental laser-induced pain in healthy participants (23) including with the electrophysiological correlate of reduced amplitude of the laser evoked potential (24). In laboratory studies with individuals with chronic musculoskeletal pain, 4 min of 10 Hz sensory stimulation has been shown to successfully entrain alpha and decrease pain (25) and the degree of frontal alpha power increase is found to correlate with the reduction in pain (moderate strength correlation, Pearson r 0.33 for pain intensity, 0.40 for pain unpleasantness) (26). To our knowledge alpha entrainment has not previously been used pre-sleep in those with chronic pain, but other forms of noninvasive brainwave entrainment have been investigated for use at night in the home environment in this group.…”
