| Popis: | A treatment option in a selected group of patients with chronic non-specific low back pain is percutaneous radiofrequency denervation of lumbar zygapophyseal joints (RDLZJ). These joints and the lumbar paravertebral musculature are innervated by the dorsal rami of the lumbar spinal nerves. It has been stated that the effectiveness of the procedure can be deduced from the finding of electromyographic signs of denervation in the paraspinal muscles. This study was designed to test the following: Does RDLZJ cause spontaneous muscle fibre activity of the paraspinal muscles? Is pain relief after a RDLZJ correlated with the presence of spontaneous activity in the paraspinal muscles?In a prospective observer-blind study, twenty-eight patients with a history of at least one year of chronic low back pain were selected on the basis of a positive response to a diagnostic nerve blockade and subsequently randomly assigned to one of two treatment groups. Each patient in the RF treatment-group (14 patients) recei... |
