The correlation between VR analgesia and conditioned pain modulation
SD, pain
Analyses indicate a significant correlation between how much VR + Yes real water reduced worst pain ratings, and reduction in worst pain during CPM (Pearson r = 0.46, Similarly, in exploratory post-hoc analyses, participants with smaller than average CPM analgesia still showed a statistically significant (25% VR analgesia) reduction in worst pain during mixed reality: ”No VR” = 4.53, (SD = 1.31) versus VR + real water = 3.38, (SD = 1.59), Z = 2.79, The subset of participants with larger than average CPM during Phase 1 showed a much larger (46% VR analgesia) reduction in worst pain (i.e., greater VR analgesia) during mixed reality: (No VR Mean = 4.77, (SD = 1.13) versus VR + Yes real water (mean = 2.57, SD = 1.66), Z = 3.65,
