military members experience PTSD but only 23% seek medical help. Emory physicians described one of the strongest indicators of PTSD to be avoidance, saying this inhibits those affected from seeking treatment. PE requires that the patient close their eyes and relate the pertinent episode in as much detail as possible. The methodology was based on the concept that in facing the event, the charge of the triggers may be attenuated over time. The VRET application BRAVEMIND differs from PE in that the patient does not reimagine the episode but instead wears a headset that places them in the familiar environment. This headset is equipped with two screens (one for each eye), headphones, and a position monitor that shifts the visual scene to match the patient's head movements. Depending on the patient's experience they may be standing or sitting on top of a raised platform with a bass shaker. This allows for vibrations that simulate the experience of riding a military vehicle. Other accessories such as joysticks or mock machine guns are given to the patients, if appropriate, to enhance realism. The clinician introduces triggers, such as gunfire, explosions, etc. into the virtual environment as they see fit. The clinician can also adapt sound and lighting conditions to match the patient's description. The researchers who developed the BRAVEMIND system reported that in a 20-patient trial, the patients' scores on the diagnostic PTSD checklist–military version (PCL-M) dropped from 54.4 pre-treatment to 35.6 post-treatment after eleven sessions. In another clinical trial, consisting of 24 active-duty soldiers, it was reported that after 7 sessions 45% no longer were identified as positive for PTSD while 62% demonstrated symptomatic improvement. These experimental results were compared with those of alternative PE treatments. The BRAVEMIND software has 14 different environments available including military barracks, Iraqi markets, and desert roads. Included in these are environments specific to military sexual trauma (MST). Designed environments such as U.S. base settings, shower areas, latrines, remote shelters, and others were developed after consulting subject matter experts from Emory University. Proponents of this research have said that with military based videogames being so prevalent, this technology may be more appealing to patients and reduce the stigma surrounding treatment. They also have argued that as research on PTSD unfolds, possible subtypes may respond to treatments differently, and therefore diversifying treatment options is best. Others have expressed reservations about the capacity to properly personalize VRET for
