40 patients with lumbar pain and lower limb pain who visited the Watanabe Hospital, were randomly divided into 2 groups and nerve-root blocks were performed: Group (+) : Received concomitant administration of steroid with local anesthetic at the time of nerve-root block ; Group (-) : Received administration of local anesthetic alone at the time of nerve-root block. The Visual Analog Scale (VAS) and Present Pain Intensity (PPI) scales were used when compairing outcomes between the groups : (1) before nerve-root block, (2) 1 hour post nerve-root block, and (3) 1 week after the nerve-root block. There was no statistically significant difference in VAS and PPI between the Group (+) and Group (-) at any of the studied intervals. The efficacy of nerve-root block is assumed to be attributable to the pharmacological action of local anesthetic that interrups the pain cycle, induces remission from pain and recovers the spontaneous healing power, thereby achieving persistent therapeutic effect.
