Interest of Cardiac Coherence in the Prevention of Chronic Post-traumatic Stress Disorder: Pilot Study

Centre Hospitalier Universitaire de la Réunion44 enrolled

Overview

ThThe aim of this study is to determinate the potential benefits of a respiratory training program (cardiac coherence, CC) in patients suffering from acute stress disorder, after a potentially traumatic event. Using this method is supposed to prevent the onset of chronic post traumatic stress disorder after 3 months. This pilot study will help to determinate the need of developing this kind of complementary and alternative program, and will also provide knowledge about the feasibiility and acceptability of this program for the patients.

Each patient will be teached how to use cardiac coherence with a trained practitioner at the inclusion visit. A respiratory guide on smartphone will be given to the patient aswell as a diary in order to keep tracks of the patient's compliance to this program.
