Hypnosis in virtual worlds help burn victims with pain

Oregon Live ran this story about a new technology being used at the Oregon Burn Center at Legacy Emanuel Medical Center in Portland: virtual reality hypnosis for dressing changes for burn victims.

Dressing changes are extremely painful but need to done multiple times per day, sometimes for weeks. They are definitely the "sore spot" in burn care, elevating the stress and tension in patients that slows healing and has patients thinking of ways to avoid it, bringing on compliance problems.

Patients are distracted by flying and performing tasks using a computer mouse in an immersive virtual world called SnowWorld with hypnotic scenery, music and pacing.

In clinical trials, burn patients using SnowWorld reported 35 to 50 percent reductions in pain. The system was developed at the University of Washington by research scientist Hunter Hoffman and psychologist David Patterson, with input from burn care experts at Harborview Burn Center in Seattle.

Patterson's group has received a grant from the National Institutes of Health for a controlled clinical trial of virtual reality hypnosis for chronic pain.
