The goal of this article is to provide a thorough literature review of available noninvasive and alternative treatment options for chronic low back pain. In particular, the efficacy of each therapy is evaluated and pertinent outcomes are described. ⋯ There are a wide variety of noninvasive and alternative therapies for the treatment of chronic low back pain. Those with the strongest evidence in the literature for good efficacy and outcomes include exercise therapy with supervised physical therapy, multidisciplinary biopsychosocial rehabilitation, and acupuncture. Therapies with fair evidence or moderately supported by literature include yoga, back schools, thermal modalities, acupressure, and cognitive-behavioral therapy. Those therapies with poor evidence or little to no literature support include manipulation, transcutaneous electrical nerve stimulation, low-level laser therapy, reflexology, biofeedback, progressive relaxation, hypnosis, and aromatherapy. Providers delivering care for patients with chronic low back pain must carefully evaluate these available treatment options related to their efficacy or lack thereof as well as relevant outcomes.

Electrical peripheral nerve stimulation (PNS) is discussed as an effective neuromodulatory treatment in chronic pain. This human experimental study hypothesized a rightward shift of stimulus-response function as a marker of antinociceptive and analgesic PNS effects. ⋯ Modulation of laser pain threshold, perceptual ratings, and LEP indicates a rightward shift of stimulus-response function under PNS. These data emphasize antinociceptive and analgesic effects of PNS in an experimental human model and support its clinical neuromodulative relevance.

Low back pain (LBP) is a highly prevalent condition and one of the leading causes of lost productivity and health-care costs. The objective of this review is to discuss the role of interventional pain procedures and evidence of their effectiveness in treatment of chronic LBP. ⋯ Implementation of interventional pain procedures in the treatment framework of LBP has resulted in improvement of pain intensity in at least the short and medium terms, but equivocal results have been observed in functional improvement.
