Pain is a noxious stimulus which can be interpreted in many ways by different individuals but as yet the mechanism by which body manages it are not completely understood. Though pain is frequently related physical causes(such as inflammatory process and nociceptive transmission of pain messages),the experience is entirely subjective.(1,2) Making Objective measurement of pain difficult. The way in which pain is perceived depends on many factors including past experiences, memory, understanding of pain ,cultural conditioning and pain threshold (6,7)Most of the patients with pain has to undergo significant physical and emotional trauma initially from their injury, subsequently from dressing changes & related treatment they undergo throughout healing phase .Moreover unrelieved pain can produce serious physiological and psychological consequences leading to increased risk of morbidity and state of central sensitisation leading to chronic pain. Virtual reality (VR) can be considered intermediary to reality and computer technology.(8) VR based interventions often have been developed as an adjunctive intervention designed to distract patients for acute pain that has not responded to conventional approaches. (3)Owing to its ability to allow the user to immerse and interact with artificial environment that he/she can visualize ,the game-playing is very engrossing. VR can give patient a perception of actually being in different environment. The rationale for using VR based distraction for acute pain is that since pain requires conscious attention.(4,5)VR draws attention into computer generated world having less attention available to process incoming signals. One of the major challenges of living with persistent pain is that pain is typically increased when patient moves painful body area, the increase in pain that occurs during movement can be substantial and can lead to avoidance and will become fearful of daily activities such as walking, changing from one position to another.(9) VR potentially provides a way of exposing patients to movements that they may avoid because of pain/fear.
