Does Virtual Reality Help Reduce Nerve Injuries Pain?

Conditioned pain modulation (CPM) is dysfunctional in patients with nerve injury, so by knowing what can enhance its action, scientists can help stimulate the body's natural pain inhibiting process.

Yes, virtual reality (VR) can help in reducing pain caused due to nerve injuries and can boost the dysfunctional pain suppression system, reveals a new study.

The study, published in The Journal of Pain, showed that VR can also reduce pain symptoms such as prickling and pain following touch, that are often seen in patients with nerve injury.

Symptoms & Signs For Nerve Damage
Our nervous system is involved in numerous functions such as sensing touch and pain, breathing, digestion, limb movement, passing urine, and emptying bowels. Imagine what would happen if nerves get damaged due to disease.

"It's brilliant that we've seen these results as it shows more evidence that virtual reality can not only reduce pain perception in human models of chronic pain, but also gives us insight into the mechanisms behind this effect," said researcher Sam Hughes, Lecturer in Psychology at the University of Plymouth.

"The next step of course is to conduct the study with people who experience chronic pain to see if it works for them," Hughes added.

According to the researchers, we all feel physical pain in different ways, but people with nerve injuries often have a dysfunctional pain suppression system, making them particularly prone to discomfort.

How to Manage Nerve Injuries
Nerves are like the 'telephone wiring' system in human body carrying messages from brain to the other parts of the body. Any injury to nerve results in impaired transmission of reflex messages.

For the study, the team focused on conditioned pain modulation (CPM) - a pain inhibitory pathway in humans.

The team previously published work showing that watching soothing 360-degree scenes of the Arctic in virtual reality can help to ease pain symptoms similar to those experienced during sunburn.

Parents may soon be able to watch their unborn babies grow in realistic 3-D immersive visualizations.

The team have also gone one step further and measured VR's direct effects on CPM.A

Virtual Reality Treatment Helps Chinese Drug Addicts Decrease Craving
Virtual reality (VR) treatment program may help Chinese drug addicts overcome their addiction and help them off the drugs, reports a new study.

The findings indicated that 360-degree scenes of the Arctic in virtual reality had an effect on the CPM efficiency, while the 2D versions of the same scenes (described as 'sham VR') reduced CPM efficiency.

"If it does work, it could be a really helpful in forming part of ongoing pain management by helping to target the dysfunctions in the brain that underpin chronic pain," Hughes added.
