title: Complex regional pain syndrome: the role of the psychiatrist as an expert witness.
abstract: Complex regional pain syndrome (CRPS) is a regional pain syndrome of unclear pathophysiology, typically affecting the hand or foot. CRPS can be subject to personal injury litigation and may be the cause of substantial future loss of earnings claims. In clinical practice, a variety of medical experts can be involved in the diagnosis and management of CRPS and this can lead to confusion about the most appropriate expert for lawyers to instruct. This paper defines the role of psychiatrists as experts to the court in CRPS and reviews the associated psychiatric literature. Psychiatrists do not have expertise in the clinical diagnosis of CRPS, but they are able to assess the presence of co-morbid psychiatric conditions. They can assist the court as experts in the underlying neuro-physiological and psychological processes which may explain some of the important features of CRPS and an individual's psychological vulnerability to CRPS. Their expertise in psychological and psycho-pharmacological interventions should be considered for any multidisciplinary treatment programme for CRPS along with the likely contribution of these interventions to the overall prognosis.
