“…level of immersion in the VR world) related factors that may modulate the effect of VR distraction, in a study population of all ages. Previous studies showed that distraction modulates tactile perception; here we explored whether distraction through VR applications induces similar effects[14, 15]. We hypothesized that the level of interactivity and immersion in the VR world would correlate positively with a reduction in tactile perception thresholds, supporting the distraction hypothesis[17–19].…”

“…To date, distraction methods have hardly been studied in relation to tactile perception thresholds. To our knowledge, only two small studies have shown that auditory distraction and music distraction lower tactile perception thresholds[14, 15]. VR distraction has not been studied with regard to tactile perception, however many studies investigated the effect of VR in the context of pain relief.…”

BackgroundVirtual reality (VR) has shown to be an effective distraction method in health care. However, questions remain regarding individual and VR-related factors that may modulate the effect of VR.PurposeTo explore the effect of VR distraction on tactile perception thresholds in healthy volunteers, in relation to personal characteristics and interactivity of VR applications.MethodsA randomized three way cross-over study was conducted to investigate the effects of active and passive VR applications in 50 healthy participants. Main outcome measures were monofilament detection thresholds (MDT) and electrical detection thresholds (EDT). Personal characteristics (e.g. age, gender, susceptibility for immersion) and immersion in the VR conditions were analyzed for their effect on VR induced threshold differences.ResultsThe use of VR caused a significant increase in both MDT and EDT compared to the control condition (MDT: F (2, 76) = 20.174, p < 0.001; EDT F (2, 76) = 6.907, p = 0.002). Furthermore, a significant difference in favour of active VR compared to passive VR was found in MDT (p = 0.012), but not in EDT. No significant gender effect was found. There was a significant positive correlation between age and active VR distraction (r = 0.333, p = 0.018). Immersion in the VR world was positively correlated with the effect of VR, whereas visualization and daydreaming were negatively correlated with VR effects.ConclusionVR increased tactile perception thresholds, with active VR having the largest effect. Results indicate that the efficacy of VR may increase with increasing age. Gender did not affect VR susceptibility.
