[Treatment of chronic lumbosacral pain by transcutaneous electrical stimulation in laminectomized patients: preliminary results (author's transl)].

The authors have tried transcutaneous electrical stimulation for the treatment of chronic lumbosacral pain in 27 patients already treated by laminectomy without benefit. Six patients experienced a 55% mean reduction of pain; another six had a 35% reduction; and the remaining 15 a 16% reduction of pain severity. From these results and a review of published data the authors conclude that the method is of limited value in alleviating chronic lumbosacral pain in laminectomized patients.
