Eye Movement Desensitization and Reprocessing (EMDR) therapy is an extensively researched, effective psychotherapy method proven to help people recover from trauma and other distressing life experiences, including PTSD, anxiety, depression, and panic disorders.
EMDR is very good for treating mental health issues which have been triggered by a particular traumatic event or multiple traumatic events. Often after suffering these events people suffer heightened anxiety, intrusive thoughts and develop patterns of avoidance in their daily lives. EMDR is proven to alleviate these symptoms.
The advantage of EMDR is that the therapist does not need to know the finer details of the traumatic event/events and this can be very useful if the client suffers significant shame or embarrassment when talking about these events.
EMDR can be easily adapted to online work and has been successfully delivered by many therapists over Internet during the COVID lockdown. There is a very good video explaining how EMDR works on this page.
