Immersive Virtual Reality (VR) distraction can be used in addition to traditional
opioids to reduce
procedural pain. The current study explored whether a High-Tech-VR helmet (ie, a 60-degree field-of-view
head-mounted display) reduces
pain more effectively than a Low-Tech-VR helmet (a 35-degree field-of-view head-mounted display). Using a double-blind between-groups design, 77 healthy volunteers (no patients) aged 18-23 were randomly assigned to 1 of 3 groups. Each subject received a brief baseline thermal
pain stimulus, and the same stimulus again minutes later while in SnowWorld using a Low-Tech-VR helmet (Group 1), using a High-Tech-VR helmet (Group 2), or receiving no distraction (Group 3, control group). Each participant provided subjective 0-10 ratings of cognitive, sensory, and affective components of
pain, and amount of fun during the
pain stimulus. Compared to the Low-Tech-VR helmet group, subjects in the High-Tech-VR helmet group reported 34% more reduction in worst
pain (P < .05), 46% more reduction in
pain unpleasantness (P = .001), 29% more reduction in "time spent thinking about
pain" (P < .05), and 32% more fun during the
pain stimulus in VR (P < .05). Only 29% of participants in the Low-Tech helmet group, as opposed to 65% of participants in the High-Tech-VR helmet group, showed a clinically significant reduction in
pain intensity during virtual reality. These results highlight the importance of using an appropriately designed VR helmet to achieve effective VR
analgesia (see ).
PERSPECTIVE:
Pain during medical procedures (eg,
burn wound care) is often excessive. Adjunctive virtual reality distraction can substantially reduce
procedural pain. The results of the present study show that a higher quality VR helmet was more effective at reducing
pain than a lower quality VR helmet.
