Define complex regional pain
syndrome (CRPS) type 1 and type 2.
CRPS is a disease process consisting of
continuous pain, often burning in nature, usually consequent to an injury or a
noxious stimulus. CRPS usually presents with variable degrees of autonomic and
trophic changes along with sensory and motor dysfunction.
CRPS type 1 was previously known as reflex
sympa-thetic dystrophy (RSD) and CRPS type 2 was previously known as causalgia.
The nomenclature has been changed to dispel some of the old theories as to the
possible etiolo-gies for these diseases.
CRPS types 1 and 2 have similar signs and
symptoms. In CRPS type 2 a history is commonly elicited describing a gross
nerve injury, whereas with CRPS type 1 the inciting event may never be
determined.
