Sydney, June 4: Australian scientists have introduced an innovative interactive game that shows potential as a non-invasive and drug-free method for alleviating chronic nerve pain.

The initiative, named PainWaive, aims to train users in managing abnormal brain activity associated with neuropathic pain, according to reports.

Created by researchers at the University of New South Wales (UNSW), this game utilizes a headset to track brainwaves in real-time while players engage in a mobile game that rewards them for achieving healthy brainwave patterns. This could serve as a home-based alternative to pain medications like opioids.

In a recent study, three-quarters of the participants experienced notable pain relief after four weeks of using the game, with results comparable to or exceeding those typically seen with opioid treatments.

The game is designed around the altered brainwave activity observed in individuals suffering from nerve pain, particularly focusing on changes in the thalamus, a crucial relay center in the brain.

According to Sylvia Gustin, a professor at UNSW, the technology enables users to retrain their abnormal brain activity through mental techniques such as relaxation and positive visualization. The results of this study have been published in the Journal of Pain.

Dr. Negin Hesam-Shariati from UNSW’s NeuroRecovery Research Hub noted, “Participants felt empowered to manage their pain in their own environment, which is a significant aspect of what makes this approach unique.”

Participants utilized an affordable EEG (electroencephalogram) headset along with a tablet-based game at home, while researchers monitored their progress remotely.

The headset, designed with 3D printing and open-source components, costs approximately $193.7, making it significantly cheaper than commercial alternatives. It employs wet electrodes to accurately target the brain's sensorimotor cortex for pain-related readings.

Gustin emphasized that PainWaive's design focuses on accessibility for individuals who may have limited access to traditional treatment options. She also mentioned that recruitment is currently underway for two larger trials aimed at chronic spinal pain and neuropathic pain resulting from spinal cord injuries.
