A 2-group experimental design. ⋯ A higher postural sway and high correlation between pelvis and trunk displacements was found in the LBP group compared with healthy controls.

We conducted an observational study using mailed questionnaires to 3 random samples of general practitioners from Victoria and New South Wales, Australia in 1997, 2000, and 2004. ⋯ A special interest in back pain is associated with back pain management beliefs contrary to the best available evidence. This has serious implications for management of back pain in the community.

Randomized Controlled Trial
A randomized trial comparing acupuncture, simulated acupuncture, and usual care for chronic low back pain.
Acupuncture is a popular complementary and alternative treatment for chronic back pain. Recent European trials suggest similar short-term benefits from real and sham acupuncture needling. This trial addresses the importance of needle placement and skin penetration in eliciting acupuncture effects for patients with chronic low back pain. ⋯ Although acupuncture was found effective for chronic low back pain, tailoring needling sites to each patient and penetration of the skin appear to be unimportant in eliciting therapeutic benefits. These findings raise questions about acupuncture's purported mechanisms of action. It remains unclear whether acupuncture or our simulated method of acupuncture provide physiologically important stimulation or represent placebo or nonspecific effects.

Randomized Controlled Trial
The ability of multi-site, multi-depth sacral lateral branch blocks to anesthetize the sacroiliac joint complex.
To determine the physiologic effectiveness of multi-site, multi-depth sacral lateral branch injections. ⋯ Multi-site, multi-depth lateral branch blocks are physiologically effective at a rate of 70%. Multi-site, multi-depth lateral branch blocks do not effectively block the intra-articular portion of the SIJ. There is physiological evidence that the intra-articular portion of the SIJ is innervated from both ventral and dorsal sources. Comparative multi-site, multi-depth lateral branch blocks should be considered a potentially valuable tool to diagnose extra-articular SIJ pain and determine if lateral branch radiofrequency neurotomy may assist one with SIJ pain.

Review Meta Analysis
Analgesic effects of treatments for non-specific low back pain: a meta-analysis of placebo-controlled randomized trials.
Estimates of treatment effects reported in placebo-controlled randomized trials are less subject to bias than those estimates provided by other study designs. The objective of this meta-analysis was to estimate the analgesic effects of treatments for non-specific low back pain reported in placebo-controlled randomized trials. ⋯ This meta-analysis revealed that the analgesic effects of many treatments for non-specific low back pain are small and that they do not differ in populations with acute or chronic symptoms.
