The clinical efficacy of Shi-style lumbar manipulations for symptomatic degenerative lumbar spondylolisthesis: protocol for a randomized, blinded, controlled trial

BackgroundSymptomatic degenerative lumbar spondylolisthesis (DLS) presents spinal problems in daily life. Shi-style lumbar manipulation (SLM), as an alternative treatment for DLS, is popular in China. SLM is based on the channels and collaterals theory of the traditional Chinese medicine, in which the symptoms are believed to result from channel blockage and joint displacement. However, there is no solid evidence to show the effect of the SLM on the management of symptomatic DLS.Methods/designWe conduct a prospective randomized, blinded, controlled trial to compare the effectiveness of SLM with mechanical lumbar traction and explore whether it could be a potential therapy for symptomatic DLS. A total of 60 patients with symptomatic DLS will be enrolled and treated with the SLM or mechanical lumbar traction for 2weeks. VAS score and SF-36 questionnaire were assessed at baseline and at 2, 4, 12, and 24weeks. Any signs of acute adverse reactions, such as lower limb paralysis or syndrome of cauda equina, will be recorded at each visit during treatment.DiscussionAlthough the SLM has been used in China for many years to treat symptomatic DLS, there is a lack of consensus about its effectiveness. This trial will provide convincing evidence about the effect of SLM on symptomatic DLS.Trial registrationRegistered on 6 January 2019; the trial number is ChiCTR1900020519.
