According to Bados (2006), the problems with panic and agoraphobia are very frequent in clinical practice; specifically, these are the anxiety problems which people consult about most and they constitute around 50-60% of the phobia cases attended in the clinic (Bados, 2009). In general, if population data of primary health care is analyzed, numbers will show a higher prevalence than in the general population.
Virtual reality (VR) seems to be a good alternative regarding traditional techniques of exposure in the treatment of agoraphobia. Unlike in vivo exposure, virtual reality allows standardization and control over the exposure session parameters. Moreover, this technology is particularly useful for repeating the exposure of the feared situations as many times as necessary (Botella et al, 2004). It also prevents panic attacks, losing the risk of reinforcing the existing fear.
