Uses of Virtual Reality (VR) for Chronic Pain
Quality of evidence in virtual reality therapy is a major current limitation; therefore, future studies should aim to address this issue.
Abstract
Chronic pain affects many people worldwide with significant individual impact and societal cost. One such area involves the psychiatric co-morbidities associated with chronic pain. Despite its prevalence, the underlying mechanism of chronic pain is not fully understood although evidence suggests the importance of biologic, psychologic, and social factors in the perception of pain. Virtual reality has the potential to be a powerful therapeutic option for chronic pain. This may be due to its impact on attention, emotion, and potentially central nervous system plasticity. Virtual reality therapy has been used successfully for a variety of chronic pain conditions showing its potential. It has also been safely used in pediatric populations. However, the major current limitation is quality of evidence; therefore, future studies should aim to address this issue.
