To determine the proportion of chronic low back pain patients who achieve a clinically meaningful response from different pharmacologic and nonpharmacologic treatments. ⋯ Exercise, oral NSAIDs, and SNRIs (duloxetine) provide a clinically meaningful reduction in pain, with exercise being the only intervention that demonstrated sustained benefit after the intervention ended. Future high-quality trials that report responder analyses are required to provide a better understanding of the benefits and harms of interventions for patients with chronic low back pain.

Epidural injections have been extensively used since their description in 1901, and steroids since their first utilization in 1952. Multiple randomized controlled trials and systematic reviews have reached discordant conclusions regarding the effectiveness of sodium chloride solution and steroids in managing spinal pain. True placebo-controlled trials with the injection of an inactive substance to unrelated structures have been nonexistent. Consequently, the discussions continue to escalate, seemingly without proper discourse. In this review, we sought to assess the true placebo nature of saline and the effectiveness of steroids. ⋯ The findings of this systematic review and meta-analysis show that epidurally administered sodium chloride solution and sodium chloride solution with steroids may be effective in managing low back and lower extremity pain. Consequently, the findings of this review provide information that epidurally administered sodium chloride solution is not a true placebo.

Review Case ReportsEvaluating and Managing the Patient with Back Pain.
A review of the literature, including recent guidelines and original studies, has informed this detailed description of best clinic practices used to evaluate, diagnose, treat, and manage adult patients who present to the outpatient clinic with complaints of low back pain. A case-based format helps guide the reader through clinical decision making and the key learning objectives.

Chronic low back pain (CLBP) is often treated with opioid analgesics (OA), a class of medications associated with a significant risk of misuse. However, little is known about how treatment with OA affect the brain in chronic pain patients. Gaining this knowledge is a necessary first step towards understanding OA associated analgesia and elucidating long-term risk of OA misuse. ⋯ CLBP patients medicated with OA showed loss of volume in the nucleus accumbens and thalamus, and an overall significant decrease in signal to noise ratio in their sub-cortical areas. Power spectral density analysis (PSD) of frequency content in the accumbens' resting state activity revealed that both medicated and unmedicated patients showed loss of PSD within the slow-5 frequency band (0.01-0.027 Hz) while only CLBP patients on OA showed additional density loss within the slow-4 frequency band (0.027-0.073 Hz). We conclude that chronic treatment with OA is associated with altered brain structure and function within sensory limbic areas.

Observational Study
Visit Frequency and Outcomes for Patients Using Ongoing Chiropractic Care for Chronic Low-Back and Neck Pain: An Observational Longitudinal Study.
Chronic spinal pain is prevalent and long-lasting. Although provider-based nonpharmacologic therapies, such as chiropractic care, have been recommended, healthcare and coverage policies provide little guidance or evidence regarding long-term use of this care. ⋯ This 3-month window on chiropractic patients with CLBP and/or CNP revealed that they were improving, although slowly; may have reached maximum therapeutic improvement; and are possibly successfully managing their chronic pain using a variety of chiropractic visit frequencies. These results may inform payers when building coverage policies for ongoing chiropractic care for patients with chronic pain.
