Background ContextAcute back pain and sciatica are major sources of disability. Many medical interventions are available, including manipulations, with conflicting results.PurposeTo assess the short- and long-term effects of spinal manipulations on acute back pain and sciatica with disc protrusion.Study Design/SettingRandomized double-blind trial comparing active and simulated manipulations in rehabilitation medical centers in Rome and suburbs.Patient Sample102 ambulatory patients with at least moderate pain on a visual analog scale for local pain (VAS1) and/or radiating pain (VAS2).Outcome MeasuresPain-free patients at end of treatment; treatment failure (proportion of patients stopping the assigned treatment for lack of effect on pain); number of days with no, mild, moderate, or severe pain; quality of life; number of days on nonsteroidal anti-inflammatory drugs; number of drug prescriptions; VAS1 and VAS2 scores; quality of life and psychosocial findings; and reduction of disc protrusion on magnetic resonance imaging.MethodsManipulations or simulated manipulations were done 5 days per week by experienced chiropractors, with a number of sessions which depended on pain relief or up to a maximum of 20, using a rapid thrust technique. Patients were assessed at admission and at 15, 30, 45, 90, and 180 days. At each visit, all indicators of pain relief were used.ResultsA total of 64 men and 38 women aged 19-63 years were randomized to manipulations (53) or simulated manipulations (49). Manipulations appeared more effective on the basis of the percentage of pain-free cases (local pain 28 vs. 6%; p<.005; radiating pain 55 vs. 20%; p<.0001), number of days with pain (23.6 vs. 27.4; p<.005), and number of days with moderate or severe pain (13.9 vs. 17.9; p<.05). Patients receiving manipulations had lower mean VAS1 (p<.0001) and VAS2 scores (p<.001). A significant interaction was found between therapeutic arm and time. There were no significant differences in quality of life and psychosocial scores. There were only two treatment failures (manipulation 1; simulated manipulation 1) and no adverse events.ConclusionsActive manipulations have more effect than simulated manipulations on pain relief for acute back pain and sciatica with disc protrusion.
