Chiropractic manipulation is mostly used for spinal problems but, in an increasing number of cases, also for non-spinal conditions. This systematic review is aimed at critically evaluating the evidence for or against the effectiveness of this approach. ⋯ Only very few randomised clinical trials of chiropractic manipulation as a treatment of non-spinal conditions exist. The claim that this approach is effective for such conditions is not based on data from rigorous clinical trials.
