“…These mechanisms are still not fully known, as well as parameters of Virtual Environment (VE) which contribute to pain alleviation. Several published studies tested various properties of VEs but failed to find significant differences in their effectiveness [8,9,10,11,12]. Mühlberger et al [8] studied the effect of VE content on hot/cold pain stimuli endurance.…”

“…Dependent variables were pain tolerance (the time participants kept their hand in cold water), pain intensity (ratings on a Visual Analogue Scale), and presence (Igroup Presence Questionnaire results). In previous studies we had investigated the influence of interface on analgesic effect [12], but the results had not been conclusive -therefore in this study we tried to increase the difference in body movement necessary to navigate the game, and used a custom made VE in order to achieve greater control over confounding variables.…”

In this study, we tested the hypothesis that increased body movement while steering a virtual reality game leads to the diminished experience of pain. We also investigated the relationship between presence in a virtual environment and pain intensity. 30 students of Wroclaw University participated in the within subject experiment. The participants were looking at the game through head mounted displays. In two experimental conditions a participant navigated the game using a computer mouse (a small movement), or a Microsoft Kinect (a large movement). Thermal (cold) stimulation was used to inflict pain. While playing the game, the participants immersed their nondominant hands in a container with cold water (temperature 0.5 -1.5°C). Two measures were used to assess the pain experiencethe amount of time the participants spent keeping their hands in cold water (pain tolerance), and Visual Analogue Scale (pain intensity). The participants also completed the Igroup Presence Questionnaire (IPQ), measuring the sense of presence experienced in a virtual environment.The predictions were partly confirmed by the resultsthe participants were keeping their hands in cold water significantly longer in the large movement condition compared to the small movement condition. However, there was no significant difference on pain intensity results between the two experimental conditions. Similarly, we failed to find any correlations between IPQ dimensions and the pain measures used in the study. Several possible mechanisms underlying the observed relationship between movement and pain experience are discussed.
