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.

Randomized Controlled Trial Comparative Study
Impact of chronic musculoskeletal pathology on older adults: a study of differences between knee OA and low back pain.
The study aimed to compare the psychological and physical characteristics of older adults with knee osteoarthritis (OA) vs those of adults with chronic low back pain (CLBP) and to identify psychological and physical predictors of function as measured by gait speed. ⋯ Older adults with chronic pain may have distinct psychological and physical profiles that differentially impact gait speed. These findings suggest that not all pain conditions are the same in their psychological and physical characteristics and may need to be taken into consideration when developing treatment plans.

Randomized Controlled Trial
Low-frequency transcranial magnetic stimulation in patients with fibromyalgia and major depression.
To study the efficacy of low-frequency transcranial magnetic stimulation in patients with fibromyalgia and major depression. ⋯ With the methodology used in this study, patients with fibromyalgia and major depression who received real magnetic stimulation did not present significant differences in symptoms with respect to those who received sham magnetic stimulation.

Randomized Controlled Trial Multicenter Study Comparative Study
N-of-1 randomized trials to assess the efficacy of gabapentin for chronic neuropathic pain.
The objective of this study was to compare the efficacy of gabapentin with placebo for neuropathic pain at the individual and population levels. ⋯ The response rate and mean reduction in symptoms with gabapentin were small. Gabapentin prescribing posttrial was significantly influenced by the trial results.

Randomized Controlled Trial
Brain functional changes and duloxetine treatment response in fibromyalgia: a pilot study.
Serotonin-norepinephrine reuptake inhibitor (SNRI) antidepressant medications may have efficacy in relieving pain associated with fibromyalgia syndrome (FMS), even in the absence of major depressive disorder (MDD). Current practice is to use a trial-and-error treatment strategy, often requiring 8-12 weeks to determine the effectiveness of a given pharmacological intervention. The ability to predict response to antidepressant medications would facilitate clinical management of FMS. Prior work in MDD has shown that the quantitative electroencephalographic (QEEG) cordance biomarker of brain functional changes early in the course of antidepressant treatment is related to later clinical response. We hypothesized that cordance might also predict response to antidepressant medications for symptoms of FMS. ⋯ This pilot study suggests that QEEG biomarkers may prove useful for predicting improvement in painful symptoms during SNRI treatment in FMS. Larger studies are needed to confirm this finding.
