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.
patients seen at medico-psychological emergency cell
patients with an acute stress disorder, diagnosed by DSM-5
patients who have experienced a potentially traumatic event for the last 3-15 days (vctim or witness)
patients able to read and write in French language
patients with respiratory pathology not allowing cardiac coherence training
patients currently practicing a regular respiratory control technique or within the last 6 months
patients taking beta-blocker, betamimetic, anti-arrhythmic, opioid, antidepressant
patients with a pacemaker or suffering from severe cardiac illness
Single group
cardiac coherence
Other interventionstandard care associated to cardiac coherence training during 3 months
Proportion of patients without Post-traumatic stress disorder
Measured by the Post Traumatic Stress Disorder CheckList for DSM-5 (PCL-5)
Complications associated to Post-traumatic stress disorder
number of suicide attempt
Complications associated to Post-traumatic stress disorder
Variation of suicidal risk (Columbia-Suicide Severity Rating Scale or C-SSRS). This scale measure the risk of suicide et will be measured by un external evaluator
