How they work
EMDR
Core mechanism: Bilateral stimulation during trauma memory processing facilitates adaptive information processing and memory reconsolidation (proposed)
Ontology: Unprocessed trauma memories stored dysfunctionally with original affect, sensation, and cognition
Imagery Rehearsal Therapy
Core mechanism: Cognitive rescripting of nightmare content combined with imagery rehearsal changes nightmare frequency and distress through mechanisms likely involving memory reconsolidation and reduced conditioned fear
Ontology: Nightmares as a learned maladaptive sleep behavior that can be directly targeted and modified through intentional cognitive and imaginal intervention

What each assumes — and misses
EMDR
Philosophical roots: Merleau-Ponty (body holds memory); Bion (processing/containment); Pavlov (orienting response); Shapiro (adaptive information processing — pragmatic, not philosophically derived)
Blind spots: Mechanism debate unresolved; protocol fidelity varies; may be applied to conditions beyond its evidence base
Therapeutic voice: Bring up the image and the negative belief. Notice what you feel in your body. Now follow my fingers.
Imagery Rehearsal Therapy
Philosophical roots: Behavioral learning theory; cognitive appraisal; Lang's emotional processing theory; sleep science
Blind spots: Requires willingness to engage with nightmare content; some find rescripting counterintuitive; not suitable during acute destabilization; limited training infrastructure
Therapeutic voice: Choose any part of the nightmare and change it any way you want. It does not have to make sense. Then we will rehearse the new version.
Choosing between them
EMDR (Trauma-Focused) and Imagery Rehearsal Therapy (Cognitive-Behavioral) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
