“…Before conducting this study we had finished two experimental studies using the same display technology and the same virtual environments, where a non-VR control condition was included. Both of these studies have found the large and significant increase of pain tolerance in VR conditions comparing to the non-VR condition [11,22]. General pain alleviating effect of VR has also been supported by numerous studies done by others, using similar pain stimulation (a cold pressor test), and various hardware and software VR technologies [13,9,23].…”

“…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.…”

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.

180‐degree immersive VR motion visualization in the treatment of haemophilic ankle arthropathy

Background: Patients with haemophilic arthropathy suffer chronic pain that affects and restricts their quality of life. Visualization of movement through immersive virtual reality is used for pain management. Aim:To evaluate the efficacy of 180-degree immersive VR motion visualization therapy in patients with haemophilic ankle arthropathy.Methods: Prospective, multicentre pilot study. Fifteen adult patients with bilateral haemophilic ankle arthropathy were recruited (mean age: 42.73 ± 12.36 years). The intervention lasted 4 weeks, with daily home sessions of 180-degree immersive motion visualization. The patients were given virtual reality glasses to use with their smartphones. From the YouTube mobile app® they accessed the recorded video with access from the He-Mirror App®. The study variables were joint state (Haemophilia Joint Health Score), pressure pain threshold (pressure algometer), muscle strength (dynamometry) and range of motion (goniometry). Three evaluations were performed: at baseline (T0), after the intervention (T1) and at the end of a 16-week follow-up period (T2). Results:No patient developed ankle hemarthrosis during the experimental phase. In the repeated measures analysis we found statistically significant differences in joint state (F = 51.38; η 2 p = .63), pressure pain threshold of the lateral malleolus (F = 12.34; η 2 p = .29) and range of motion (F = 11.7; η 2 p = .28). Conclusions: Therapy using immersive motion visualization does not cause hemarthrosis. This intervention can improve joint condition, pressure pain threshold and range of motion in patients with ankle arthropathy. Changes greater than the MDC were reported in more than 40% of patients for the variables pressure pain threshold, anterior tibialis strength and range of motion, which were considered clinically relevant.

Social support of virtual characters reduces pain perception

BackgroundPsychosocial factors, such as social support, can reduce pain. Virtual reality (VR) is a powerful tool to decrease pain, but social factors in VR‐based pain analgesia have rarely been studied. Specifically, it is unclear whether social support by virtual characters can reduce pain and whether the perceived control behind virtual characters (agency) and varying degrees of social cues impact pain perception.MethodsHealthy participants (N = 97) received heat pain stimulation while undergoing four within‐subject conditions in immersive VR: (1) virtual character with a low number of social cues (virtual figure) provided verbal support, (2) virtual character with a high number of social cues (virtual human) provided verbal support, (3) no social support (hearing neutral words), (4) no social support. Perceived agency of the virtual characters served as between‐subjects factor. Participants in the avatar group were led to believe that another participant controlled the virtual characters. Participants in the agent group were told they interacted with a computer. However, in both conditions, virtual characters were computer‐controlled. Pain ratings, psychophysiological measurements and presence ratings were recorded.ResultsVirtual social support decreased pain intensity and pain unpleasantness ratings but had no impact on electrodermal activity nor heart rate. A virtual character with a high number of social cues led to lower pain unpleasantness and higher feelings of presence. Agency had no significant impact.ConclusionsVirtual characters providing social support can reduce pain independent of perceived agency. A more human visual appearance can have beneficial effects on social pain modulation by virtual characters.SignificanceSocial influences are important factors in pain modulation. The current study demonstrated analgesic effects through verbal support provided by virtual characters and investigated modulating factors. A more human appearance of a virtual character resulted in a higher reduction of pain unpleasantness. Importantly, agency of the virtual characters had no impact. Given the increasing use of digital health interventions, the findings suggest a positive impact of virtual characters for digital pain treatments.
