Low-back pain is a common condition and a substantial economic burden in industrialized societies. A large proportion of patients with chronic low-back pain use complementary and alternative medicine (CAM), visit CAM practitioners, or both. Several herbal medicines have been purported for use in low-back pain. ⋯ Harpagophytum Procumbens, Salix Alba and Capsicum Frutescens seem to reduce pain more than placebo. Additional trials testing these herbal medicines against standard treatments are needed. The quality of reporting in these trials was generally poor. Trialists should refer to the CONSORT statement extension for reporting trials of herbal medicine interventions.

Randomized Controlled Trial Comparative Study
The effect of sedation on diagnostic validity of facet joint nerve blocks: an evaluation to assess similarities in population with involvement in cervical and lumbar regions (ISRCTNo: 76376497).
Zygapophysial or facet joint pain in patients suffering with chronic spinal pain without disc herniation or radiculopathy may be diagnosed with certainty by the use of controlled diagnostic blocks. But, in patients suffering with either lumbar or cervical facet joint pain, even this diagnostic approach may be confounded by false-positives when using a single diagnostic block. It may also be confounded by the administration of anxiolytics and narcotics prior to, or during, the controlled diagnostic facet joint blocks. The effect of sedation on the validity and potential differential results in patients suffering with combined cervical and lumbar facet joint pain has not been evaluated. ⋯ Perioperative administration of sodium chloride, midazolam, or fentanyl can confound results in the diagnosis of combined cervical and lumbar facet joint pain. False-positive results with placebo or sedation may be seen in a small proportion of patients.

Effects of chronic low back pain on trunk coordination and back muscle activity during walking: changes in motor control.
Low back pain (LBP) is often accompanied by changes in gait, such as a decreased (preferred) walking velocity. Previous studies have shown that LBP diminishes the normal velocity-induced transverse counter-rotation between thorax and pelvis, and that it globally affects mean erector spinae (ES) activity. The exact nature and causation of these effects, however, are not well understood. ⋯ The gait of the LBP participants was characterized by a more rigid and less variable kinematic coordination in the transverse plane, and a less tight and more variable coordination in the frontal plane, accompanied by poorly coordinated activity of the lumbar ES. Pain intensity, fear of movement and disability were all unrelated to the observed changes in coordination, suggesting that the observed changes in trunk coordination and ES activity were a direct consequence of LBP per se. Clinically, the results imply that conservative therapy should consider gait training as well as exercises aimed at improving both intersegmental and muscle coordination.

The sacroiliac joint (SIJ) is a putative source of low back pain. The objective of this article is to provide clinicians with a concise review of SIJ structure and function, diagnostic indicators of SIJ-mediated pain, and therapeutic considerations. The SIJ is a true diarthrodial joint with unique characteristics not typically found in other diarthrodial joints. ⋯ Conservative management includes manual medicine techniques, pelvic stabilization exercises to allow dynamic postural control, and muscle balancing of the trunk and lower extremities. Interventional treatments include sacroiliac joint, intra-articular joint injections, radiofrequency neurotomy, prolotherapy, cryotherapy, and surgical treatment. The evidence for intra-articular injections and radiofrequency neurotomy has been shown to be limited in managing sacroiliac joint pain.

Comparative Study
Development of a German version of the Oswestry Disability Index. Part 1: cross-cultural adaptation, reliability, and validity.
Patient-orientated assessment methods are of paramount importance in the evaluation of treatment outcome. The Oswestry Disability Index (ODI) is one of the condition-specific questionnaires recommended for use with back pain patients. To date, no German version has been published in the peer-reviewed literature. ⋯ The mean baseline ODI scores differed significantly between the surgical and conservative patients (P < 0.001), and between the different categories of the Likert scales for disability, medication use and pain frequency (in each case P < 0.001). Our German version of the Oswestry questionnaire is reliable and valid, and shows psychometric characteristics as good as, if not better than, the original English version. It should represent a valuable tool for use in future patient-orientated outcome studies in German-speaking lands.
