The EMDR therapist takes over the role of assisting the patient through processing their trauma. As an outsider, it is easier for the therapist to see where the patient is at and where the patient needs to go and can lead the patient on the right path.
The patient and the EMDR therapist will work together to create a goal that the patient wants to accomplish. The therapist needs to understand how far the client is willing/can go to achieve relief from the traumatic event.
When the client encounters a block along the healing process, it is the therapist’s job to detect the issue and efficiently support the patient in navigating around or through it—making sure it won’t become an issue again. The therapist might not know what the block is until it has mostly been cleared, but it is possible to achieve by working together. Still, the therapist has more of a supporting and guiding role than taking control. It is the patient who will be in control of the procedure.
