Future directions: advances and implications of virtual environments designed for pain management.

Pain symptoms have been addressed with a variety of therapeutic measures in the past, but as we look to the future, we begin encountering new options for patient care and individual health and well-being. Recent studies indicate that computer-generated graphic environments--virtual reality (VR)--can offer effective cognitive distractions for individuals suffering from pain arising from a variety of physical and psychological illnesses. Studies also indicate the effectiveness of VR for both chronic and acute pain conditions. Future possibilities for VR to address pain-related concerns include such diverse groups as military personnel, space exploration teams, the general labor force, and our ever increasing elderly population. VR also shows promise to help in such areas as drug abuse, at-home treatments, and athletic injuries.

Quantifying the effectiveness of virtual reality pain management: a pilot study.

Sensory pathways, consisting of chains of neurons, which spread from the receptor organ to the cerebral cortex, are responsible for the perception of sensations (including pain). In this study, we set out to determine how effective virtual reality (VR) could be in distracting patients from pain experienced through thermoreceptors on the skin. Six healthy subjects were exposed to uncomfortable pain stimuli with and without VR distraction. Subjects reported a drop in pain while in the VR environment, and mean pain rating was significantly lower than the session with no VR distraction. These results indicate that VR distraction can diminish pain experienced by subjects, thus we conclude by eliciting future directions for quantifying effectiveness of VR as a pain management solution.
