Management of acute and chronic low back and leg pain often includes the use of acupuncture. The effectiveness of this form of therapy is dependent upon compliance, which in turn is dependent on availability, response, treatment of proper acupoints, and the placebo effect. We hypothesized that classical acupuncture would be more effective than placebo acupuncture. One hundred and thirty-two patients with acute and chronic low back and leg pain were examined before and after surgery for lumbar disc protrusion. Diagnosis was based on CT and MRT findings. Patients received acupuncture drug-free throughout the study period. The visual analogue scale was used to assess pain intensity before and after (i.e. 30 min. 60 min. 2 h and 6 h) acupuncture. Classical acupuncture resulted in a significant reduction in pain that become increasingly stronger during the 6h study period. Placebo acupuncture lead to same early pain relief that did not reach statistic significant and then declined thereafter.
