A prospective study was undertaken to evaluate the efficacy of spinal cord stimulation (SCS) in the management of chronic pain syndrome. The study included all patients who underwent this procedure at the Royal Melbourne Hospital and the Melbourne Private Hospital over a period of two years. A total of 29 patients were managed by the end of June 1996. These patients were carefully screened by a neurosurgeon (JVR) and a psychiatrist. Of these, 26 patients had a follow up evaluation at the end of August 1996. From the group of 29 patients, four patients failed to obtain any relief during the trial phase of the procedure and thus did not have the stimulator implanted permanently. From the 25 patients who proceeded to have the stimulator implanted, 11 patients had a variable beneficial response, three patients found it to be of marginal benefit, six had no benefit, three patients initially had a good response but subsequently gained no benefit whilst two patients were uncertain of its benefit. It thus appears that SCS was of benefit in 50% of our carefully selected patients with chronic pain syndromes. (C) 2000 Harcourt Publishers Ltd.
