Classification of Chronic Pain, Second Edition (Revised)

Descriptions of Chronic Pain Syndromes and Definitions of Pain Terms

Note: The IASP Taxonomy (based on Part III) was updated in 2011 by the IASP Taxonomy Working Group. View the newest definitions and notes here. IASP would like to thank the members of the Special Interest Group on Pain of Urogenital Origin (now known as the SIG on Abdominal and Pelvic Pain) for their eight years of work developing the new classifications pertaining to their field. It's a tremendous effort and their dedication is impressive and admirable. The hardworking members are: Andrew Baranowski, Chairman of PUGO's Classification Committee, Paul Abrams, Richard Berger, Tony Buffington, Beverly Collett, Anton Emmanuel, Magnus Fall, Phil Hanno, Fred Howard, John Hughes, Curtis Nickel, Jorgen Nordling, Dean Tripp, Katy Vincent, Ursula Wesselmann, and Amanda C de C Williams.

Part III: Pain Terms: A Current List with Definitions and Notes on Usage


Classification of Chronic Pain was originally published in 1986, with a second edition published in 1994. Updates were made to selected sections in 2011 and 2012, including the pain definitions (taxonomy). Going forward, because the material will be updated on a periodic and continual basis by IASP's pain experts, this book will no longer be available in a print version. In support of IASP's educational mission, the contents will instead be freely available for download from this website.

This taxonomy book is available online as a reference only. Please contact IASP for permission to use, reprint or translate any IASP publications.
