Exposure Therapy
JUST A TOOL! VRT Excruciating pain - skin stretching
Morphine doesn't help - distractions do
Brain controls the pain
Send the mind elsewhere... ... how about Snow World?
... or maybe Spider World? For burn patients
Playing Nintendo, reported EXTREME pain
Not so much pain when in Spider World "Virtual reality is not just changing the way patients interpret coming pain signals; the programs actually reduce the amount of pain-related activity" Human attention like a "spot light"
Less attention available Blood pressure cuff to cause pain
