Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Radiofrequency denervation of lumbar facet joints in the treatment of chronic low back pain: a randomized, double-blind, sham lesion-controlled trial.
Radiofrequency facet joint denervation procedures have been common practice for 2 decades in treatment of chronic low back pain. We designed this multicenter, randomized, double-blind, sham treatment controlled trial to determine the efficacy of radiofrequency facet joint denervation, as it is routinely performed. ⋯ The combined outcome measure and VAS showed no difference between radiofrequency and sham, though in both groups, significant VAS improvement occurred. The global perceived effect was in favor of radiofrequency. In selected patients, radiofrequency facet joint denervation appears to be more effective than sham treatment.

To summarize and to analyze the available literature on the efficacy of intra-articular injections of corticosteroids for low back pain. ⋯ The apparent efficacy of lumbar intra-articular steroids is no greater than that of a sham injection. There is no justification for the continued use of this intervention. Better outcomes can be achieved with deliberate placebo therapy.

Randomized Controlled Trial Clinical TrialRandomized, controlled trial of breath therapy for patients with chronic low-back pain.
Patients suffering from chronic low back pain (cLBP) are often unsatisfied with conventional medical care and seek alternative therapies. Many mind-body techniques are said to help patients with low back pain by enhancing body awareness, which includes proprioception deficit in cLBP, but have not been rigorously studied in cLBP. Breath therapy is a western mind-body therapy integrating body awareness, breathing, meditation, and movement. Preliminary data suggest benefits from breath therapy for proprioception and low back pain. ⋯ Patients suffering from cLBP improved significantly with breath therapy. Changes in standard low back pain measures of pain and disability were comparable to those resulting from high-quality, extended physical therapy. Breath therapy was safe. Qualitative data suggested improved coping skills and new insight into the effect of stress on the body as a result of breath therapy. Balance measures did not seem to be valid measures of clinical change in patients' cLBP.

Prospective cohort study of randomly selected Veterans Affairs out-patients without baseline low back pain (LBP). ⋯ Depression is an important predictor of new LBP, with MRI findings likely less important. New imaging findings have a low incidence; disc extrusions and nerve root contact may be the most important of these findings.

Morphologic analysis of bipolar radiofrequency lesions: implications for treatment of the sacroiliac joint.
Sacroiliac (SI) joint dysfunction is an important cause of mechanical low-back pain. Bipolar radiofrequency ablation has been proposed as a long-lasting treatment for pain in patients with SI dysfunction who report temporary pain relief with local-anesthetic injection into the joint. No data are available to guide the technical aspects of bipolar radiofrequency lesion creation. This study documents the optimal spacing of cannulae and time required to produce bipolar lesions by use of radiofrequency technology. ⋯ Bipolar radiofrequency treatment creates continuous "strip" lesions proportional in size to the distance between the probes when the distance between cannulae is 6 mm or less. Spacing the cannulae 4 to 6 mm apart and treating at 90 degrees C for 120 to 150 seconds maximizes the surface area of the lesion.
