Within the ongoing search to discover a ache intervention that does away with the necessity for opioids – and bypasses medication altogether – a brand new game-based system has proven big promise in tackling power neuropathic ache. Utilizing a sport and a headset, it “trains” sufferers to rewire mind indicators with a view to relieve ache.
Researchers at UNSW Sydney have examined their brainwave-monitoring neural suggestions sport system on members with corneal neuropathic ache (CNP), a situation wherein dysfunctional eye nerves trigger a set of discomfort together with gentle sensitivity, burning sensations, stabbing ache and broader discomfort across the face and cranium.
They discovered that 4 weeks of gameplay with the animated program and accompanying brain-monitoring headset, confirmed that 75% of members had a big discount in ache – and it matched a stage that was both on par with opioids and even higher. Nonetheless, there’s a catch: It was a really small trial, with simply 4 individuals, so whereas the outcomes are constructive, they’re simply step one.

“Restrictions within the examine’s measurement, design and period restrict our potential to generalize the findings or rule out placebo results,” mentioned Dr Negin Hesam-Shariati from UNSW’s NeuroRecovery Analysis Hub. “However the outcomes we’ve seen are thrilling and provides us confidence to maneuver to the subsequent stage and our bigger trial.”
The therapy in query is named PainWave, a novel remedy that mixes a game-like app with a headset that screens the mind, instantly feeding again to the on-screen visuals. The visuals include a cute animated jellyfish underwater, and as brainwaves shift, the water adjustments shade. The affected person can see real-time suggestions of mind exercise – because the thoughts calms, the murky water turns gentle turquoise – which inspires the person to “practice” their thoughts to control patterns related to power nerve ache.
The sufferers accomplished 20 intervention periods over 4 weeks, and have been additionally assessed 5 weeks post-trial, after being inspired to proceed with the practices they’d been educated on utilizing the sport.
“This trial demonstrates the potential of EEG neurofeedback to cut back ache severity and interference in people with corneal neuropathic ache,” the researchers wrote of their examine. “It additionally highlights person preferences for technology-based interventions, emphasizing ease of use, accessibility, and self-administration to boost adherence, particularly for people with restricted mobility or restricted healthcare entry.”
It makes use of electroencephalographic (EEG) neurofeedback to empower the affected person to basically reorganize these haywire neural pathways and in flip relieve the ache they’re triggering.
The undertaking is the newest step in UNSW Professor Sylvia Gustin’s analysis concentrating on the thalamus, a small area within the mind chargeable for relaying info. On this case, the data it is dealing with pertains to neuropathic (nerve) ache. Gustin has been working to unravel the thriller of the thalamus and neuropathic ache for greater than a decade, and the newest developments could be traced again to a paper she authored in 2014.
“The brainwaves of individuals with neuropathic ache present a definite sample: extra sluggish theta waves, fewer alpha waves, and extra quick, excessive beta waves,” she mentioned. “We consider these adjustments intervene with how the thalamus talks to different components of the mind, particularly the sensory motor cortex, which registers ache.”
Whereas the PainWave periods have been initially guided by researchers, earlier than lengthy the sufferers have been in a position to conduct these assigned periods with their pill and headset on their very own. On the identical time, their mind knowledge was relayed again to the UNSW workforce to observe and assess.
“All the pieces besides the open-source EEG board was constructed in-house,” mentioned Hesam-Shariati. “And shortly, even that might be changed by a custom-designed board.”

Utilizing 3D printing, the researchers have been in a position to minimize the price of the EEG headsets to round AU$300 (US$200), which is a fraction of what industrial fashions are priced at.
“We’ve labored carefully with sufferers to make sure the headset is light-weight, comfy, and user-friendly,” mentioned Gustin. “Proudly owning the know-how affords us the potential to at some point provide PainWaive as a very reasonably priced, accessible resolution for at-home ache administration, particularly for these with restricted entry to conventional remedies.”
Now, the workforce has its sights on a randomized managed trial that can take a look at the system on 224 members with neuropathic ache because of spinal twine damage. The researchers are actively recruiting for the Spinal Pain Trial, which is able to assess PainWave’s potential to cut back power spinal ache, and the StoPain Trial, testing the system on individuals with power neuropathic ache from spinal twine damage.
“A lot of our workforce are clinician-scientists, and we’re centered on growing sensible remedies that may be built-in into the healthcare system,” mentioned Gustin. “It’s extremely inspiring to see outcomes that assist unlock the mind’s potential to heal itself and convey again hope to individuals dwelling with ache.”
