title: Chronic pain after spinal cord injury: clinical characteristics.
abstract: The clinical characteristics of chronic pain in spinal cord injury patients are controversial. The authors prospectively evaluated 81 patients with chronic pain due to spinal cord lesions. The mean pain intensity according to the visual analogue scale was 9.4. The most common description of pain was a sensation of burning. The initial pain was more severe in patients presenting with myelopathy due to gunshot injuries (p < 0.001). The pain intensity was not associated with the magnitude of the spinal lesion, location of the lesion, occurrence of myofascial pain syndrome or onset of pain. Pain after spinal cord injury was severe, males were more frequently affected and it was more intense when it was the result of gunshot injury. In about 38% of the patients, pharmacological and rehabilitative procedures were effective. Dorsal root entry zone lesion was effective for the treatment of transitional pain in patients with complete section of the spinal cord, spinal cord stimulation was effective for patients with partial lesions of the spinal cord and intrathecal opioid infusion was effective for both conditions.
