models have been proposed.8 Although a number of
systematic reviews have investigated spinal manipulative
therapy for LBP, a firm conclusion on its
effectiveness has not been reached.2,9,10 Due to the
poor methodological quality of the reviewed studies,
the reviewers have been unable to conclusively
support or reject the claim that spinal manipulative
therapy is an effective treatment for patients with
LBP. More recently, nine randomised controlled
trials investigating spinal manipulative therapy for
LBP have reported statistically significant results. To
evaluate the results of these trials and to present the
most current information regarding this issue, an
updated systematic review is required. To this end,
the current systematic review aimed to investigate
recent evidence for the efficacy of spinal manipulative
therapy in patients with LBP.
