简要总结
Post-traumatic stress disorder (PTSD) is a set of symptoms that can be developed as a result of exposure to a traumatic event or events that can range in prevalence from 25% to 75%. While therapeutic management combines psychotherapy, drug therapy and social support, some PTSD remain resistant after early and appropriate initial treatment. In terms of physiopathology, several studies have shown that parasympathetic activity is significantly decreased in patients with PTSD. In scuba diving, the cardio-vascular stresses associated with submersion of the subject and the lungs due to breathing in a regulator are at the origin of a reflex activation of the parasympathetic nervous system. The objective is to study the effects of the scuba diving activities-induced autonomic parasympathetic nervous system activation on the symptomatic progression of patients with PTSD.
The study population will consist of patients monitored and treated for PTSD following the attacks of 14/07/2016 in Nice (France).
详细描述
A group will be composed of patients (n=12) who will complete a Scuba Diving Discovery Course (GP+ Diving Group). This course, lasting 2 weeks, will consist of a daily dive, 5 days per week, for a total of 10 dives. These will be supervised by a graduate instructor according to the rules of supervision defined by the sport code. The dives will be conducted in open air, at a maximum depth of 6 meters for a maximum duration of 20 minutes.
A matched group (gender, age, height, weight and BMI) will be composed of patients (n=12) who will not complete the Scuba Diving Discovery Course (GP- Virtual reality group). The subjects of this group will follow virtual reality sessions recreating the environment in which the scuba divers of the GP+ group operate. A control group (GT) will be composed of patients (n=12) who are monitored and treated for PTSD and who will not attend the dive discovery course or virtual reality sessions.
- The main evaluation criterion will be the NON-INVASIVE determination of salivary alpha amylase.
- Secondary evaluation criteria will be heart rate variation, CGI, HAD and BECK Anxiety, EGF, PCL-S and IES questionary.
The main objective is to study the effects of immersion and pressure relief ventilation on the activation of the autonomic parasympathetic nervous system.
Secondary objectives are to assess the symptomatic impact of parasympathetic autonomic nervous system activation on overall improvement, anxiety and depressive symptoms, functioning, and the 3 subtypes of PTSD symptoms as vegetative neuro hyperactivity, invasive syndrome and avoiding
