Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA prospective crossover comparison study of the single-needle and multiple-needle techniques for facet-joint medial branch block.
Medial branch blocks have been widely described in the literature as a diagnostic tool for facet joint pain. Recently, a new "single-needle' technique was described that is purported to be equally accurate, and in some respects, superior to the standard multiple-needle technique. To date, no studies have been performed that compared these 2 techniques. ⋯ Our results indicate that the single-needle technique takes less time to perform and causes less patient discomfort than does the standard technique but provides the same degree of accuracy. More studies with larger sample sizes are needed to corroborate these results and explore the effect the single-needle approach has on the rate of false-positive medial branch blocks.

Prolotherapy, an injection-based treatment of chronic musculoskeletal pain, has grown in popularity and has received significant recent attention. The objective of this review is to determine the effectiveness of prolotherapy for treatment of chronic musculoskeletal pain. ⋯ There are limited high-quality data supporting the use of prolotherapy in the treatment of musculoskeletal pain or sport-related soft tissue injuries. Positive results compared with controls have been reported in nonrandomized and randomized controlled trials. Further investigation with high-quality randomized controlled trials with noninjection control arms in studies specific to sport-related and musculoskeletal conditions is necessary to determine the efficacy of prolotherapy.

Sacroiliac joint dysfunction is believed to be a significant source of low back and posterior pelvic pain. ⋯ A reliable examination technique to identify the sacroiliac joint as a source of low back pain seems to be pain relief following a radiologically guided injection of a local anaesthetic into the sacroiliac joint. Most patients respond to non-operative treatment. Patients who do not respond to non-operative treatment should be considered for operative sacroiliac joint stabilization.

Randomized Controlled Trial Comparative Study Clinical TrialLumbar spine segmental mobility assessment: an examination of validity for determining intervention strategies in patients with low back pain.
To examine the predictive validity of posterior-anterior (PA) mobility testing in a group of patients with low back pain (LBP). ⋯ Patients with LBP judged to have lumbar hypomobility experienced greater benefit from an intervention including manipulation; those judged to have hypermobility were more likely to benefit from a stabilization exercise program.

Comparative Study
A longitudinal study on the predictive validity of the fear-avoidance model in low back pain.
Recently, fear-avoidance models have been quite influential in understanding the transition from acute to chronic low back pain (LBP). Not only has pain-related fear been found to be associated with disability and increased pain severity, but also treatment focused at reducing pain-related fear has shown to successfully reduce disability levels. In spite of these developments, there is still a lack in well-designed prospective studies examining the role of pain-related fear in acute back pain. ⋯ A backward ordinal regression analysis showed previous LBP history and pain intensity to be the most important predictors of end of study GCPS. Of the fear-avoidance model variables, only negative affect added to this model. Our results do not really support the longitudinal validity of the fear-avoidance model, but they do feed the discussion on the role of pain-related fear in early stages of LBP.
