Abstract
Objective. To evaluate the results of chronic electrical stimulation of the spinal cord (SCS) in patients with pain syndromes following various operations in the spine.
Material and Methods. Implantation of chronic SCS systems was performed in 100 patients during 2001-2012. Average pain syndrome duration before application of neurostimulation was 5.5 years. In 12 patients, SCS was combined with peripheral nerve stimulation due to individual pain features. The indications for surgery were persistent pain of neurogenic nature in the back and limbs, and positive results of test stimulation. Pain severity, its influence on the quality of life, and needs for analgesics were assessed using the modified ten-point VAS. The Multivariate Verbal-Color Pain Test was used to assess a proportion of neuropathic, somatogenic and psychogenic components of pain syndrome. Results were assessed in the early postoperative period, at 6 and 12 months, and then once a year.
Results. In the early postoperative period 45 patients reported excellent, 37 - good, and 18 - satisfactory results. In the follow-up period results remained excellent in 28, good in 37, and satisfactory in 15 patients.
Conclusions. Epidural spinal cord stimulation is a highly effective method, which allows managing pain syndrome in the long-term follow-up. Chronic stimulation effects are completely reversible and safe.
