EMDR is a form of psychotherapy which works for many sufferers of post-traumatic stress disorder. The 'eye movement desensitisation and reprocessing' technique was first developed in the USA in the late 1980s by Francine Shapiro. She set up an EMDR Institute and Ashley Byrne has been speaking to psychologist Dr Gerald Puk, one of its senior trainers.
