Chapter 11 - Painful conditions affecting the nerve roots and plexus

from Section 3 - The Specific Condition: Peripheral Neuropathic Pain


This chapter describes commonly used peripheral nerve injury models of neuropathic pain. It introduces the central, non-traumatic and orofacial models of neuropathic pain. Neuropathic pain of central origin is observed clinically after traumatic incidents, such as stroke or spinal cord injury (SCI). An important consideration is that the pain experience, in humans and animals, has both sensory and emotional dimensions. The focus on nociception in pain research has been associated with the clinical failure of several potential pain medicines. An understanding of both sensory and affective dimensions of pain may improve translational research. Further, interpretations made from animal nerve injury models should be considered in the context of gender, age, and species/strain studied. Finally, it appears that no animal nerve injury model is without limitations, therefore, behavioral, physiological, and biochemical studies can only speculate on the relevance of experimental findings to human neuropathic pain.
