Movement Sonification as an add-on to Immediate Post-event Psychotherapeutic Intervention in the Management of Acute Stress Disorder: a Feasibility and Acceptability Study

In France, IPPI is carried out by the medical-psychological emergency units (CUMP) in each department. Patients are referred to these units by the CUMPs themselves when they are called out by the SAMU (emergency medical service) to the scene of mass accidents (attacks, fires, suicides in public places, etc.), or by departmental doctors and medico-legal emergency services for individual EPTs (sexual or physical assault, etc.). In Seine-Saint-Denis, the CUMP 93 receives 60 to 100 patients per year in the immediate post-traumatic phase. The purpose of IPPI is to reconnect the traumatic experience with known representations. These interventions have demonstrated effectiveness,although their preventive impact on PTSD remains limited. Movement sonification is an augmented auditory reality technique that transforms a patient's movements into sound through connected wristbands and a speaker system. By enriching bodily perception, this technique may enhance the efficacy of trauma-focused psychotherapies. This study aims to assess the acceptability and feasibility of using movement sonification in combination with IPPI for the treatment of ASD. It thereby addresses an urgent need for primary prevention of PTSD.
