Brief Summary
Catalepsy seems to facilitate hypnotic induction and deepen hypnotic trance, although no work confirms the usefulness of this technique which is in common use in hypnosis. Furthermore, it has been shown that the hypnotic trance state is accompanied by an increase in parasympathetic tone, the non-invasive measurement of which is easy by the ANI monitor (Analgesia Nociception Index). The research hypothesis is that, by adding a body dissociation, catalepsy could facilitate and intensify the hypnotic trance, the intensity of which can be monitored and is proportional to the parasympathetic tone.
