Eye Movement Desensitization and Reprocessing (EMDR) has been shown effective in treating psychological consequences of traumatic or hurtful experiences. It has been used e.g. in people who developed post-tramatic stress disorder after serving as soldiers or who were sexually abused. In my experience it can also be combined with other treatment options such as cognitive behaviour therapy and/or hypnosis.


Wikipedia provides an informative overview over EMDR. Here is an excerpt:


"Eye Movement Desensitization and Reprocessing (EMDR) is a form of psychotherapy that was developed to resolve symptoms resulting from disturbing and unresolved life experiences. It uses a structured approach to address past, present, and future aspects of disturbing memories. The approach was developed by Francine Shapiro to resolve the development of trauma-related disorders as resulting from exposure to a traumatic or distressing event, such as rape. Clinical trials have been conducted to assess EMDR's efficacy in the treatment of post-traumatic stress disorder (PTSD). In some studies it has been shown to be equivalent to cognitive behavioral therapy or exposure therapy


EMDR's most unique aspect is an unusual component of bilateral stimulation of the brain, such as eye movements, bilateral sound, or bilateral tactile stimulation coupled with cognitions, visualized images and body sensation.


The theory underlying EMDR treatment is that it works by helping the sufferer process distressing memories more fully which reduces the distress. EMDR is based on a theoretical information processing model which posits that symptoms arise when events are inadequately processed, and can be eradicated when the memory is fully processed. It is an integrative therapy, synthesizing elements of many traditional psychological orientations, such as psychodynamic, cognitive behavioral, experiential, physiological, and interpersonal therapies.''
