Objective. To evaluate effectiveness of spinal cord stimulation (SCS) applied to complex regional pain syndrome I (CRPS I). To analyze trends to focus the design of a multicenter prospective study. ⋯ Frequencies > 250Hz were necessary in some patients to maintain or re-establish pain control. Bilateral multielectrode leads appear superior with application of multiple arrays, permitting paresthesia steering without need for surgical revision. A multicenter, prospective design is needed applying dual-lead multichannel systems with high frequency capabilities in the treatment of CRPS I.

Spinal cord stimulation has become an accepted technique used in the management of chronic neuropathic pain syndromes. However, a number of problematic questions remain unanswered. This introduction states some of these problems and concentrates on the problem of whether low back pain can be relieved by stimulation. This paper introduces subsequent contributions to this symposium, which offer some interesting new techniques, and attempts to answer some of the problems presented.

The following account discusses the possible mechanisms by which spinal cord stimulation can control symptoms of Complex Regional Pain Syndromes. A review of the literature with a methodology for its incorporation in a treatment algorithm and associated technical aspects is suggested.
