Answer

Due to a lack of information on the pathophysiology of CRPS and the similar absence of consistent objective diagnostic criteria, clinical trials that demonstrate effective therapies are difficult to perform. Therefore, only a few evidence-based treatment regimens are currently available. In fact, 4 literature reviews and outcome studies found very little consistent information regarding the pharmacological agents and methods available for the treatment of CRPS. [75, 76, 77]
