  Objectives: The precise causes of Complex Regional Pain Syndrome (CRPS) are as yet not well known. Some consider CRPS type 1 without apparent nerve injury to arise due to a prolonged inflammatory state after initial trauma and its underlying pathophysiology indicates Nociceptive/Inflammatory Pain (NocP) components. Yet others have shown clear direct evidence of nerve injury in CRPS type 1-affected limbs, and they consider CRPS type 1to be Neuropathic Pain (NeP). The McGill Pain Questionnaire (MPQ) has the potential to diagnose pain disorders as well as suggest the underlying pathophysiology. Methods: We investigated pain characteristics of 165 NeP and 66 NocP patients, by using the 78 words of the MPQ, and thereby developed a discriminant function which efficiently discriminates NocP from NeP. We then applied this function to 36 CRPS type 1 .. View More»
