Distraction isn't only way virtual reality might ease pain

(Reuters Health) - Virtual reality games might help ease pain not just by distracting players from what ails them, but also by triggering changes in the brain, a recent research review suggests.

Distraction may indeed play a role in pain relief, the review of six small studies suggests. But its also possible that the technology could help produce changes in the nervous system when its used to help reprogram how a person responds to pain.

Guided imagery has long been a treatment for psychological disorders, and virtual reality is a more immersive way to provide guided imagery, said lead study author Dr. Anita Gupta of the Woodrow Wilson School of Public and International Affairs at Princeton University in New Jersey.

More research is needed to tell if virtual reality is truly effective, but having more options to treat pain is promising, Gupta said by email.

Virtual reality technology has been around for decades, first coming to prominence when the military used it for flight simulators. The earliest hardware filled an entire room, but as the technology has become smaller and cheaper to produce, its increasingly being used for a variety of medical purposes including wound care, physical therapy, dental pain relief and burn treatment.

Today, mass-produced virtual reality devices may require no more than a smartphone and special headsets to operate, and a growing number of people use these gadgets to play video games and take lifelike, three-dimensional tours of places they might not be able to visit in real life.

For the current study, researchers reviewed articles published from 2000 to 2016 that explored different ways virtual reality might augment pain relief.

Altogether, researchers identified four small experiments that randomly assigned some patients to try virtual reality for pain relief as well as two pilot studies of the technology for this use.

In addition to acute pain, several studies looked at chronic pain states such as headaches or fibromyalgia. These studies also combined virtual reality with other treatments such as biofeedback mechanisms and cognitive behavioral therapy.
