The authors of this article use self-citation almost exclusively to substantiate statements inaccurately depicted as being representative of the general scientific literature. Three examples highlight this practice: (1) Imaging of the spine is an essential element of modern chiropractic and manual therapy; (2) Several clinical studies have demonstrated that spine rehabilitation programs, customized for the specific patients spinal misalignment, provide better patient outcomes versus traditional standardized approaches of the past (and present); and (3) Similarly, randomized clinical studies, on patients with lumbar spine hypolordosis (but not hyperlordosis) using extension traction methods to restore lordosis, have shown long-term relief from low-back pain . . . Each of these statements references the authors’ own work. Self-citation is not necessarily inappropriate but can be a surrogate marker of distortions of the scientific literature toward specific opinions and biases. Second, the scientific literature is inconsistent regarding a causal association between alterations in spinal sagittal curvature and spinal pathology. A 2008 systematic review concludes there is “no strong evidence for any association between sagittal spinal curves and any health outcome, including spinal pain.” A 2017 systematic review and metaanalysis concluded there was a strong relationship between low-back pain and decreased lumbar lordotic curvature, while a 2018 cross-sectional study determined no significant correlation existed between lumbar lordosis and pain levels for people with chronic low-back pain. Lastly, the authors fail to discuss the significant problem of false-positive findings in spinal imaging studies, the result of which is overutilization of health-care services. A 2015 systematic review found that between 37% and 96% of asymptomatic individuals had disk degeneration, between 4% and 83% of asymptomatic patients had facet degeneration, and between 2% and 50% of asymptomatic patients had spondylolisthesis (increasing prevalence with age). Of 26 interventions classified as “low value care,” imaging for nonspecific low-back pain was the most utilized, accounting for between $82 million and $226 million per year.
