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...

Research in animals shows that the levels of neuropathic pain expression is genetically associated with a characteristic response profile to sensory stimuli. The aim of the present investigation was to examine if pressure algometry can identify a specific pain sensitivity profile in patients with complex regional pain syndrome, Type I (reflex sympathetic dystrophy), and to distinguish complex r...

Results: Compared with patients who had warm CRPS, patients who had cold CRPS more often reported a history of serious life events (p 0.05) and chronic pain disorders (p 0.05). In cold CRPS, the incidence of CRPS-related dystonia was increased (p 0.05), and cold-induced pain had a higher prevalence (p 0.01). Furthermore, QST revealed a predominant sensory loss in patients with cold CRPS (p 0.05...
