The following sites provide additional information on trauma research, evaluation and treatment  including sites which are specific to EMDR psychotherapy:


The EMDR International Association is a professional association of EMDR clinicians and establishes standards for EMDR practice, research, and training.  EMDRIA also maintains a listing of certified EMDR clinicians, approved consultants, and approved instuctors.

A very complete collection of EMDR research articles published from 1989 through 2005 have been listed by David Baldwin on his Trauma Information Pages website.

EMDRIA Definition of EMDR:  The definition of EMDR as adopted by the EMDR International Association.


The International Society for Traumatic Stress Studies (ISTSS) provides information on trauma treatment, education, research and prevention.  It holds an annual conference for clinicians and researchers and publishes, in print, the Journal of Traumatic Stress and, on the web, a quarterly newsletter, Stress Points.

David Baldwin’s Trauma Information Pages has an excellent collection of trauma articles from the late 1980s through the 1990s.  Included are articles by Van der Kolk, Porges, Perry, and many other traumatologists.

Bessel van der Kolk, M.D., internationally-known traumatologist, has published very useful information regarding trauma and treatment on his Trauma Center website. This includes clinical articles available via the Trauma Center website as well as information on PTSD assessment instruments.

Bruce Perry, M.D. has published numerous clinical articles on child trauma and treatment which are available via the Baldwin and Van der Kolk websites above.

The Sidran Institute provides copies of the Dissociative Experiences Scale (DES) and the Adolescent Dissociative Experiences Scale (A-DES) copyright-free.


The Institute of HeartMath was established many years ago and has conducted extensive research into the physiology of stress and has developed very useful methods for interrupting the stress response and re-training the autonomic nervous system for health and improved performance.  Use the following links  to explore the HeartMath products and literature that I have found to be clinically helpful in preparatory work with EMDR clients.:

The emWave Pro desktop system includes the integrated biofeedback software and hardware used for tracking heart rate variability.  Used in training the client in RSA breathing pattern or other breathing pattern, this can help identify a specific breath rhythm pattern which will help the client quickly quiet a state of over arousal.  The standard package comes with a sensor which clips on an earlobe..  This package is designed for the clinician’s office.  Some clients will benefit from the use of this package in their home or office after having been trained in the clinician’s office.  This package is an excellent system at a very low price for a clinical biofeedback system.  While I do use other systems for more involved work, this is my principal system for preparing clients for EMDR reprocessing.  For more information about the emWave Pro desktop training system, click here.

The emWave 2 handheld personal stress reliever is a portable unit which allows the client to practice arousal management skills outside of the clinician’s office.  It provides auditory and visual feedback and can be used in any setting, eg. metro, bus, office, or home.  Regular practice with this unit will help the client develop the ability to interrupt the stress response and to quiet states of overarousal.  Clinicians who are not comfortable with installing or using new software will find this unit to be very user-friendly and while not as full-featured as the emWave Package above, it is an excellent unit for helping the client identify and practice specific breathing patterns, imagery methods, or other interventions which will be effective in interrupting the stress response.  This unit includes an ear sensor.  Apps and hardware are now available for use of iPhones and Android phones.  For more information about emWave 2 by HeartMath click here.

The inner balance system utilizes your smartphone to provide biofeedback.  It includes a bluetooth earclip sensor which provides input to your smartphone.  For information     click here.

The HeartMath Store has a good selection of books, CDs, and stress reduction training resources.
