No pain relief with the rubber hand illusion . The sense of body ownership can be easily disrupted during illusions and the most common illusion is the rubber hand illusion . An idea that is rapidly gaining popularity in clinical pain medicine is that body ownership illusions can be used to modify pathological pain sensations and induce analgesia . However , this idea has not been empirically evaluated . Two separate research laboratories undertook independent randomized repeated measures experiments , both designed to detect an effect of the rubber hand illusion on experimentally induced hand pain . In Experiment 1 , 16 healthy volunteers rated the pain evoked by noxious heat stimuli ( 5 s duration ; interstimulus interval 25 s ) of set temperatures ( 47° , 48° and 49°C ) during the rubber hand illusion or during a control condition . There was a main effect of stimulus temperature on pain ratings , but no main effect of condition ( p = 0.32 ) , nor a condition x temperature interaction ( p = 0.31 ) . In Experiment 2 , 20 healthy volunteers underwent quantitative sensory testing to determine heat and cold pain thresholds during the rubber hand illusion or during a control condition . Secondary analyses involved heat and cold detection thresholds and paradoxical heat sensations . Again , there was no main effect of condition on heat pain threshold ( p = 0.17 ) , nor on cold pain threshold ( p = 0.65 ) , nor on any of the secondary measures ( p < 0.56 for all ) . We conclude that the rubber hand illusion does not induce analgesia .
