Moorehouse and Keen 1993 Name Changed ISAP CRPS DEFINED CHRONIC PROGRESSIVE NERVE DISORDER DYSFUNCTION IN THE CONTROL OF THE CENTRAL AND PERIPHERAL NERVOUS SYSTEM A COMPLEX BETWEEN SENSORY, MOTOR, ANS AND IMMUNE SYSTEM CHARACTERIZED BY PAIN, SWELLING, AND SKIN CHANGES. AFFECT ANY BODY PART

TREATMENTS BOTULIUM TOXIN KETAMINE NMDA BLOCKING INFUSION COMA CONCLUSION CRPS: complex form of neuropathic pain associated with hyperpathia, neurovasuclar,instability, neuroinflammation and limbic system dysfunction triggered by stimulation of neurovascular thermorecepetors c fibers sensitized to norepiephine this afferent sensory impulse leads to CRPS Early stages of up regulation super sensitivity Chronic stages shows dysfunctional of the system
ACCURATE DIAGNOSIS CONCLUSION EARLY TREATMENT PSYCHOLOGICAL SUPPORT 1 Crps both sympathetically independent pain And sympathetically maintained pain RF controversial Ablative controversial Stepwise progression for treatments
