Abstract
Diffuse burning dysesthetic sensations distal to the level of spinal injury are the most common and disabling painful sequelae of traumatic spinal cord injury (SCI). In a cross-sectional study of 19 SCI patients, clinical characteristics and results of 3 validated pain measurement instruments (McGill Pain Questionnaire, Sternbach Pain Intensity and Zung Pain and Zung Pain and Distress Scale) were used to develop a profile of function-limiting dysesthetic pain syndrome (DPS). Compared to a cohort of 147 patients admitted to the Midwest Regional Spinal Cord Injury Care System during the time period of the study, subjects were more likely to have paraplegia, incomplete sensory myelopathy, gunshot wounds to the spine and non-surgical spinal stabilization. Most patients described the pain as ''cutting,'' ''burning,'' ''piercing'' ''radiating'' and ''tight.'' The majority of patients located the pain internally and in the lower extremities. Values obtained for 6 MGill Pain Questionnaire subscales, 2 Sternbach Pain Intensity ratings and the Zung Pain and Distress index equalled or exceeded those reported for other pain syndromes. Use of these validated pain measures resulted in a systematic comprehensive assessment of function-limiting DPS following SCI.
