Abstract:

Study examined the interrater reliability of the Bryce/Ragnarsson spinal cord injury (SCI) pain taxonomy (BR-SCI-PT). Thirty-nine physicians specializing in SCI evaluated 135 vignettes, each of which described a person with SCI with one or more different etiologic subtypes of pain. Physician classifications were compared with those made by the investigators. Of 179 pain descriptions, 83 percent were categorized correctly to one of the 15 BR-SCI-PT pain types; 93 percent were categorized correctly with respect to the level (above, at, or below neurological level of injury), whereas 90 percent were categorized correctly as being either nocioceptive or neuropathic. Subjects expressed a generally high confidence in the accuracy of their classifications.
