Sterre, when the feared situation cannot be approached through live (or in vivo) exposure, other types of exposure are used. The most common is imaginal exposure, where the person closes their eyes and tries to re-live or revisit what happened, and tell the therapist what they are experiencing. The therapist guides them and helps them to stay "grounded", because dissociation can happen and can be very traumatic itself. This is sometimes called Prolonged Exposure or Flooding. If done properly, this can have very powerful therapeutic effects, as Anthony has explained here and elsewhere on this forum.
EMDR uses some techniques that are conceptually exposure-based, and in fact many therapists and researchers believe that it is the exposure component of EMDR that contributes the most to its therapeutic effectiveness.
Unfortunately, since the vast majority or published research is in English, English-speaking countries are always a few years (sometimes decades) ahead of other countries in being up-to-date with the latest treatments. It's hard to get access to specialists that can offer training, because of translation issues, and there are probably other limitations too. There is a wealth of knowledge on the Internet, though, but you need to know what is trustworthy and what isn't. Trying to improve the awareness of exposure-based therapy in the Netherlands sounds like a very worthy project :-)
