Pain-related impairment assessment by the fifth edition of the American Medical Association Guides had many ambiguous points, and therefore, it was not applicable directly in Korea. Several disputable pain disorders were excluded from the list of impairment evaluation, and complex regional pain syndrome was chosen as the first object of impairment evaluation. Scales such as Korean version of modified Barthel index for assessing the activity of daily livings and Beck Depression Inventory for assessing depression were added, and pain severity, pain treatment, pain behavior, etc. were scored. In order to objectify as much as possible and to remove the room for misuse, we develop a new rating system based on the concept of total score.
