A greater ability of subjects with high hypnotizability scores (Highs) to imagine/remember pain has been indicated as a factor of greater vulnerability to a shift from acute to chronic pain in these subjects. However, some authors reported that, in healthy Highs, only hypnotic suggestions of pain can induce imagery of pain, but not pain perception, while previous studies from our group showed that also not hypnotized Highs can experience pain during imagery of a pain previously experienced. The possible role of hypnotizability in the efficacy of pain imagery was studied in normal bipedal stance in not hypnotized (N=12) Highs and low hypnotizable subjects (Lows, N=10) during the experience of imagery-induced foot/leg pain, imagery of neutral tactile stimulation of the same leg/foot and imagery of throat pain. The results showed that only Highs perceived pain during pain imagery and displaced their body position toward the opposite leg increasing their centre of pressure mean velocity and area of excursion during leg pain perception.This supports the hypothesis that hypnotizability might be a relevant factor for the shift from acute to chronic pain and suggests that the "high risk threatening theory" (mainly based on a not unanimously accepted greater autonomic activation associated with pain imagery in Highs) should be revisited in order to assign a role to the hypnotizability-related sensori-motor integration.
