Virtual reality in the treatment of pain

Abstract

Many medical procedures produce acute pain that in most cases is quite disturbing for the individual. Medication is the treatment of choice for acute pain. However, given the involvement of psychological aspects in the experience of pain, psychological techniques are being used as an effective adjunct to alleviate pain related to medical procedures. In the last years a new technology is demonstrating an enormous potential in this field: Virtual Reality (VR) distraction. In this article we review studies that explore the efficacy of immersive VR distraction in reducing pain related to different medical procedures. We include clinical studies and analogue studies with healthy participants. We discuss the results achieved by these studies and recommend future directions of VR pain control research.
