Sensory disturbances in complex regional pain syndrome: clinical observations, autonomic interactions, and possible mechanisms.
OBJECTIVE To review mechanisms that might contribute to sensory disturbances and sympathetically-maintained pain in complex regional pain syndrome (CRPS). BACKGROUND CRPS is associated with a range of sensory and autonomic abnormalities. In a subpopulation of patients, sympathetic nervous system arousal and intradermal injection of adrenergic agonists intensify pain. RESULTS Mechanisms resp...
متن کاملThe specificity and mechanisms of hemilateral sensory disturbances in complex regional pain syndrome.
UNLABELLED Hyperalgesia often extends from the affected limb to the ipsilateral forehead in patients with complex regional pain syndrome (CRPS). To investigate whether this is more common in CRPS than other chronic pain conditions, pressure-pain thresholds and sharpness to a firm bristle were assessed on each side of the forehead, at the pain site, and at an equivalent site on the contralateral...
متن کاملrethinking the psychogenic model of complex regional pain syndrome: somatoform disorders and complex regional pain syndrome
abstract explaining the etiology of complex regional pain syndrome (crps) from the psychogenic model is exceedingly unsophisticated, because neurocognitive deficits, neuroanatomical abnormalities, and distortions in cognitive mapping are features of crps pathology. more importantly, many people who have developed crps have no history of mental illness. the psychogenic model offers comfort to ph...
متن کاملThe use of ketamine in complex regional pain syndrome: possible mechanisms.
Complex regional pain syndrome is a neuropathic pain syndrome that is characterized by: severe pain beyond the area of injury; autonomic dysregulation; neurogenic edema; movement disorder; and atrophy and dystrophy. Ketamine is an open-channel NMDA blocker that only acts on those receptors whose Mg(2+) block has been lifted. It is effective in the treatment of the syndrome when standard treatme...
متن کاملDiagnosis, mechanisms and treatment of complex regional pain syndrome.
PURPOSE OF REVIEW The incidence and disease course of complex regional pain syndrome (CRPS) has been unclear until recently. This was due to inconsistent diagnostic criteria used in previous studies and a lack of large-scale prospective datasets. Multiple mechanisms of CRPS have been suggested, and recent research has begun to explain how inflammation, the immune system and the autonomic nervou...
