Eye Movement Desensitization and Reprocessing (EMDR) is quite a mouthful to say. More importantly, it's one of the most extensively researched, efficacious treatments available for trauma and Post-Traumatic Stress Disorder (PTSD). EMDR is believed to work similarly to the processing that occurs during rapid eye movement (REM) sleep. It helps us process things that are too overwhelming for the conscious mind to make sense of.
I'm excited to report that I recently completed a 50-hour training approved by the EMDR International Association (EMDRIA). The clients I've used it with so far are in agreement - it works. I also use Emotional Freedom Techniques (EFT)/Tapping a lot, and that works for a lot of people too. While the mechanics are different (bilateral eye movements vs. tapping on energy meridian points), there are a lot of similarities between the two.
