       Diagnostic Criteria

       The diagnostic criteria were designed to provide a standardized,
       common methodology for making decisions and discern if
       unidentified pain conditions represent CRPS or not.
       The distinction in CRPS-1 and CRPS-2 is made for the presence or
       absence of nerve lesion. Type I CRPS develops following an
       initiating noxious event that may or may not have been
       traumatic, while type II CRPS develops after a nerve injury.
       No specific test is available for CRPS, which is diagnosed
       primarily through observation of the symptoms. However,
       thermography, sweat testing, x-rays, electrodiagnostics, and
       sympathetic blocks can be used to build up a picture of the
       disorder. Diagnosis is complicated by the fact that some
       patients improve without treatment. A delay in diagnosis and/or
       treatment for this syndrome can result in severe physical and
       psychological problems. Early recognition and prompt treatment
       provide the greatest opportunity for recovery.
       The International Association for the Study of Pain (IASP) lists
       the diagnostic criteria for complex regional pain syndrome I
       (CRPS I) (RSDS) as follows:
       1.
       immobilization
       2.
       nonpainful stimulus), or hyperalgesia (an exaggerated sense of
       pain) disproportionate to the inciting event
       3.
       or abnormal sudomotor activity in the area of pain
       4.
       that would otherwise account for the degree of pain and
       dysfunction.
       According to the IASP, CRPS II (causalgia) is diagnosed as
       follows:
       1.
       after a nerve injury, not necessarily limited to the
       distribution of the injured nerve
       2.
       or abnormal sudomotor activity in the region of pain
       3.
       that would otherwise account for the degree of pain and
       dysfunction.
