Immersive virtual reality (IVR) therapy has been explored as an adjunct therapy for the management of acute pain among children and adults for several conditions. Therapeutic approaches have traditionally involved medication and physiotherapy but such approaches are limited over time by their cost and side effects. This review seeks to critically evaluate the evidence for and against IVR as an adjunctive therapy for acute clinical pain applications. ⋯ This review found moderate evidence for the reduction of pain and functional impairment after IVR in patients with acute pain. Further high-quality studies are required for the conclusive judgment of its effectiveness in acute pain, to establish potential benefits for chronic pain, and for safety.

Pain is a complex common health problem, with important implications for quality of life and with huge economic consequences. Pain can be elicited due to tissue damage, as well as other multiple factors such as inflammation and oxidative stress. Can there be 1 therapeutic pathway that may target multiple etiologic factors in pain? ⋯ In this article, we show evidence for the relationships between vagal nerve activity and pain, and between vagal nerve activity and 5 factors that are etiologic to pain. Given the evidence and effects of the vagus nerve activation in pain, people involved in pain therapy may need to seriously consider activation of this nerve.
