Using VR during Experimental Ischemic pain applied to healthy volunteers showed significant improvement in VAS scores
Text Box: Results: Tolerance time to ischemia was significantly longer for VR conditions than for those without (P < 0.001). Visual Analogue Scale (0–10) ratings were recorded for pain intensity, pain unpleasantness, and the time spent thinking about pain. Affective distress ratings of unpleasantness and of time spent thinking about pain were significantly lower during VR as compared with the control condition (P < 0.003 and 0.001 respectively). Conclusions: The VR method in pain control was shown to be beneficial. The relatively inexpensive equipment will facilitate the use of VR immersion in clinical situations. Future research is necessary to establish the optimal selection of clinical patients appropriate for VR pain therapy and the type of software required according to age, gender, personality, and cultural factors.

Current Work

Virtual reality (VR) is a simulation of real or imagined experience; it can range from accurate flight simulators to imaginary games. The main effort in virtual reality is to deliver the experience via multiple senses, primary the audio-visual but also by touch, balance and smell.  One of the key telltales for successful VR experience is the Immersion effect that is the transfer from the "real" reality sense into the Virtual reality experience.

For example, a virtual reality combat game that places strong cognitive and emotional demands on the player and can change time perception, cause the patient to react as if in battle field, and change physiological parameters as well. The benefits of Virtual reality are in getting the person deeply involved in various cognitive, psychological and physiological aspects with the simulation.  VR is currently used for training, therapy and gaming.

Abstract

Background: Virtual reality immersion has been advocated as a

new effective adjunct to drugs for pain control. The attenuation of pain perception and unpleasantness has been attributed to the patient’s attention being diverted from the real, external environment through immersion in a virtual environment transmitted by an interactive 3-D software computer program via a VR helmet.

 

Objectives: To investigate whether VR immersion can extend the

amount of time subjects can tolerate ischemic tourniquet pain.

 

Methods: The study group comprised 20 healthy adult volunteers.

The pain was induced by an inflated blood pressure cuff during two separate, counterbalanced, randomized experimental conditions for each subject: one with VR and the control without VR exposure.

The VR equipment consisted of a standard computer, a lightweight

helmet and an interactive software game.
