EMDR (Eye Movement Desensitization and Reprocessing)

The working theory behind EMDR is that the brain has a natural system for processing difficult experiences into memory, filing them away as “this happened, it's over.” A traumatic experience can overwhelm that system, leaving the memory “stuck” in a way that keeps triggering the same physiological alarm response long after the danger has passed. EMDR uses bilateral stimulation, usually guided eye movements though taps or tones work too, while you briefly bring the memory to mind, and this appears to help the brain complete that filing process.

A full course of EMDR follows eight phases, starting with history-taking and resourcing (building coping skills before touching anything difficult) and only later moving into direct reprocessing of the target memory. This is a deliberate structure, not an ad-hoc technique. Your therapist won't take you into a difficult memory without first making sure you have the tools to stay regulated.

One of the more distinctive things about EMDR, compared to more talk-based trauma work, is that you don't need to narrate the traumatic event in detail, repeatedly, for it to work. You hold the memory in mind briefly while the bilateral stimulation happens; you're not required to give a full verbal account of what happened. For many people, that's a meaningful difference from what they expected trauma therapy to require.
