A 2007 American College of Physicians guideline addressed nonpharmacologic treatment options for low back pain. New evidence is now available.
To systematically review the current evidence on nonpharmacologic therapies for acute or chronic nonradicular or radicular low back pain.
Ovid MEDLINE (January 2008 through February 2016), Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and reference lists.
Randomized trials of 9 nonpharmacologic options versus sham treatment, wait list, or usual care, or of 1 nonpharmacologic option versus another.
One investigator abstracted data, and a second checked abstractions for accuracy; 2 investigators independently assessed study quality.
The number of trials evaluating nonpharmacologic therapies ranged from 2 (tai chi) to 121 (exercise). New evidence indicates that tai chi (strength of evidence [SOE], low) and mindfulness-based stress reduction (SOE, moderate) are effective for chronic low back pain and strengthens previous findings regarding the effectiveness of yoga (SOE, moderate). Evidence continues to support the effectiveness of exercise, psychological therapies, multidisciplinary rehabilitation, spinal manipulation, massage, and acupuncture for chronic low back pain (SOE, low to moderate). Limited evidence shows that acupuncture is modestly effective for acute low back pain (SOE, low). The magnitude of pain benefits was small to moderate and generally short term; effects on function generally were smaller than effects on pain.
Qualitatively synthesized new trials with prior meta-analyses, restricted to English-language studies; heterogeneity in treatment techniques; and inability to exclude placebo effects.
Several nonpharmacologic therapies for primarily chronic low back pain are associated with small to moderate, usually short-term effects on pain; findings include new evidence on mind–body interventions.

Spinal Manipulation for Patients with Chronic Low Back Pain
We read with interest the review by Chou and colleagues1 for the American College of Physicians (ACP) Clinical Practice Guideline for low back pain. We were quite disappointed that the OSTEOPATHIC Trial was excluded, as it assessed spinal manipulation in adult patients with non-specific chronic low back pain during 12 weeks of follow-up.2 Our trial results were not reported until 2013 and did not appear in systematic reviews published through the search end-date.1(Supplement Table 1) However, it is unclear why the trial was not identified in searches conducted by the authors through November 2016.1(Supplement Table 2) The exclusion of the OSTEOPATHIC Trial is important for two reasons. First, with 455 patients randomized to either active or sham treatment arms, the study is larger than any other spinal manipulation trial included in Supplement Table 2. Second, our trial initially reported a medium effect size (RR, 1.41; 95% CI, 1.13-1.76) in achieving substantial improvement (50% reduction) in pain with spinal manipulation. Identifying such risk estimates for successful pain outcomes was one of the objectives of the authors’ review. Indeed, the NIH Task Force on research standards for chronic low back pain now advocates using responder analysis, such as performed in our trial, to identify the percentage of patients achieving clinically important change.3 Interestingly, the authors cited a secondary report from our trial4 in their Discussion to note that the magnitude of treatment effects may vary according to baseline severity of pain or functional deficits. During the search period, we used other analytical methods recommended by the NIH Task Force (e.g., composite outcome measures and cumulative distribution functions) to assess spinal manipulation, including subgroup results according to baseline severity. An important finding was that spinal manipulation was associated with a large effect size (RR, 2.36; 95% CI, 1.31-4.24) in achieving recovery from chronic low back pain at 12 weeks, as defined by the composite measure of pain intensity ≤10mm/100mm and Roland-Morris Disability score ≤2/24.5 Cumulative distribution functions demonstrated better response in patients with moderate to severe baseline levels of pain and functional deficits. Readers need to be aware that our trial results indicate that spinal manipulation may be more effective in treating chronic low back pain than reported by Chou and colleagues (and, by extension, in the new ACP Guideline). Possible explanations for our positive findings include using physicians to provide spinal manipulation and adopting analytical approaches recommended by the NIH Task Force.References1.

The OSTEOPATHIC Trial (1) was identified in searches and excluded because it evaluated a multicomponent osteopathic intervention that included manipulation as well as a massage-like component (“soft tissue stretching, kneading, and pressure), myofascial stretching and release, positional treatment of myofascial tender points, and muscle energy techniques; the techniques were aimed at the back as well as the the iliac and pubic regions. According to the methods for our review (2), we excluded comparisons involving multicomponent therapy that did not meet our definition for multidisciplinary rehabilitation (a coordinated program with both physical and biopsychosocial treatment components provided by professionals from at least two different specialties) and did not compare the effects of multicomponent therapy versus individual components for assessing, because it is not possible to determine the incremental benefits of multicomponent therapy over its individual components. The OSTEOPATHIC trial was relevant for evaluating effects of baseline pain on treatment benefits, since the factor of primary interest was the severity of baseline pain rather than the specific intervention being studied, and few other trials evaluated this association. In addition to mean improvements, the proportion of patients experiencing clinically relevant improvement was an outcome evaluated in our review. However, as noted in the review, few trials reported such outcomes. Therefore, it is difficult to gauge how the OSTEOPATHIC trial findings highlighted by Licciardone and colleague compare to the studies in our review. However, the median difference reported in the OSTEOPATHIC Trial for improvement in pain scores between the osteopathic intervention and sham (9 points on a 0 to 100 pain scale) is in line with differences reported in trials of (single component) manipulation, meeting the criteria for “small” effects as defined in our methods. The OSTEOPATHIC Trial found little difference between the osteopathic intervention and sham in median scores on the Roland Morris Disability Questionnaire, a measure of back-specific function.References:1.
