About

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.

Full description

After randomization, subjects will either benefit from the normal hypnotic trance, or from the hypnotic trance associated with catalepsy of the hand.

T0 = installation in a sitting position and collection of an accompanying theme T1 = induction of the hypnotic trance (closing eyes) with restitution of the theme to the patient and suggestion of comfort over a period of 5 to 10 min T2 = validation of comfort by a pre-established signal T3 = return to consciousness (opening eyes) T4 = end of questionnaire about absorption, dissociation and time perception
