Spinal cord injury (SCI) frequently results in dysesthesias that have remained refractory to clinical treatments despite a variety of interventions. The failure of therapeutic strategies to treat dysesthesias after SCI is due to the lack of attention given to mechanisms that elicit chronic pain following SCI. An overview of the literature with respect to(More)
Spinal cord injury (SCI) results in chronic pain states in which the underlying mechanism is poorly understood. To begin to explore possible mechanisms, calcitonin gene-related peptide (CGRP), a neuropeptide confined to fine primary afferent terminals in laminae I and II in the dorsal horn of the spinal cord and implicated in pain transmission, was(More)
Spinal cord injury (SCI) results in variable motor recoveries and chronic central pain syndromes develop in the majority of SCI patients. To provide a basis for further studies, we report a new rodent model of chronic central pain following spinal cord trauma. Male Sprague-Dawley rats (N = 10) were hemisectioned at T13 and were tested both preoperatively(More)
BACKGROUND AND OBJECTIVES We describe a new approach to blocking the sciatic and saphenous nerves in the proximal thigh (level of the lesser trochanter or immediately below) using a single-penetration dual-injection (SPEDI) technique. The popliteal-sciatic approach necessitates repositioning of the leg exposing the popliteal fossa and an extra injection for(More)
